IMPORTANT Be sure to read and understand the entire

instruction manual before installing or operating the Eagle Quantum System. Only qualified personnel should install, maintain or operate the Eagle

Quantum System.

WARNING The hazardous area must be de-classified prior to

removing a junction box cover or opening a detector assembly with power applied.

CAUTION 1. The wir ing procedures in this manual are

intended to ensure proper functioning of the devices under normal conditions. However,

because of the many variations in wiring codes and regulations, total compliance to these

ordinances cannot be guaranteed. Be certain that all wiring complies with the NEC as well as all local ordinances. If in doubt, consult a

qualified official before wiring the system.

2. Some Eagle Quantum devices contain semiconductor devices that are susceptible to

damage by electrostat ic discharge. An electrostatic charge can build up on the skin and discharge when an object is touched. Always

observe the normal precautions for handling electrostatic sensitive devices, i.e. use of a wrist

strap (if available) and proper grounding.

3. To prevent unwanted actuation, alarms and extinguishing devices must be secured prior to performing system tests.

Section ISystem Overview

SYSTEM DESCRIPTION

The Eagle Quantum System serves multiple roles in the

monitoring and protection of hazardous areas. It is a“fire detection and extinguishing agent release system”

combined with a “hazardous gas monitoring system,”integrated on a fault tolerant digital communication

network. The Eagle Quantum system utilizes anadvanced distributed architecture that is equally adeptat monitoring analog process signals like combustible

or toxic gas concentrations, and discrete “contactclosure” type devices such as manual fire alarm “call

boxes” and heat detectors, as well as Det-Tronicsoptical flame detection. This sensor information is then

transmitted to the control unit to execute the firesuppression logic, to control agent release, signaling,

and annunciation outputs, and to communicate withexternal operator interface systems for configurationand monitoring.

MAJOR COMPONENT DESCRIPTIONS

The system consists of three basic components (seeFigure I-1):

INTELLIGENT FIELD DEVICES ON LOCAL OPERATINGNETWORK/SIGNALING LINE CIRCUIT (LON™/SLC)

The LON/SLC is a fault tolerant, two wire, digitalcommunication network, arranged in a loop starting andending at the Local Control Unit. The LON/SLC

supports up to 244 intelligent field devices spread overa distance of up to 32,500 feet (10,000 meters). The

LON/SLC serves as the Signaling Line Circuit (SLC) for

the fire detection/suppression aspects of the system.

that perform all the communication, command, andcontrol functions for the system. It includes all the

required operator interface controls for a fire alarmsystem (silence, acknowledge, reset, isolate),annunciation relays, a local information display, and

communication interfaces for computer basedconfiguration and monitoring of the system.

LOCAL OUTPUT UNIT (LIOU)

The LIOU consists of a rack controlled by the LCU thatcan hold up to six FenwalNet 2000 modules. These

modules allow the control of Notification ApplianceCircuits (NACs), fire suppression agent release (CO2,

Halon, FM200) using supervised relays, as well asunsupervised relays for other needs.

THEORY OF OPERATION

During normal operation, each node on the networkmonitors its attached sensor or other input, determines if

it has an alarm condition, analyzes its own health,

checks network integrity, and then packages up thisinformation for transmission to the communicationgateway, located in the LCU. This Standard Periodic

Report (SPR) contains 16 pieces of “discrete”information on the status of the node and, whereapplicable, also contains the analog value of its sensor.

At the time of node configuration, the report rate of theSPR can be set to anywhere between 1 and 10

seconds.

In the LCU the Communication Gateway collects all ofthe incoming SPRs from the field devices and puts theinformation into “datatables.” Datatables are organized

areas of memory in the gateway that can be “read” byexternal “host devices” using one of the gateway’s serial

ports. If any of the SPRs indicate an out of tolerancecondition, the gateway will display this information on its

integrated faceplate display. The gateway also has fourprogrammable relays whose action can beprogrammed to events in the SPRs of the monitored

nodes.

In addition to SPRs, nodes used as a part of the firedetection and suppression system, such as fire

detectors or Initiating Device Circuits (IDCs) interfacedwith heat detectors, manual call points, etc. send aseparate Standard Supervisory Report (SSR) to the

Logic Controller, located in the Local Control Unit. TheLogic Controller, which manages the fire suppression

logic, uses these SSR messages to verify that the nodesused in the fire alarm and suppression logic are active

and able to communicate. If the Logic Controller doesnot receive SSRs from a required node, it willannunciate a “trouble” condition.

If a “Fire Alarm” is detected by a Flame Detector orInitiating Device Circuit (IDC), the affected node will

send a special Acknowledged Exception Report (AER)directly to the Logic Controller. The AER is transmittedas soon as an alarm is detected to maximize system

performance. When the Logic Controller receives theAER, it sends the originating node a message

acknowledging its receipt. If the node originating theAER does not receive an acknowledgement, it will re-

transmit the AER until it receives an acknowledgement.This exchange of messages is used to ensure thatcritical messages are received at all appropriate

registers throughout the system.

Once the Logic Controller receives a Fire Alarmmessage from a field device, “fixed logic” will activate

built-in annunciation circuits, which consist of both avisible and audible alarm. The “programmable logic”will execute any specified voting, timing, and/or zone

logic and subsequently activate the appropriate outputcircuits for Notification Appliance Circuits (NACs), agent

release circuits, and unsupervised relay outputs.

The faceplate of the Logic Controller has twopushbuttons. “ACKNOWLEDGE” will silence the built in

audible alarm and illuminate the “Acknowledge LED”located on the faceplate next to the “Acknowledge”pushbutton. “SILENCE” will silence selected NACs in

the field and illuminate the “Silence LED” located on thefaceplate next to the “Silence” pushbutton. The Logic

Controller also features a keyswitch to reset the systemafter the event is over.

NETWORK OPERATION DURING AFAULT CONDITION

The Eagle Quantum system utilizes a unique patented

technique for detecting problems in the communicationnetwork wiring. This state-of-the-art feature minimizes

the possibility of a communication breakdown in theevent of a wiring fault in the communication loop andcan also serve as an aid in troubleshooting.

The communication network is constructed as a loop

that starts and ends at a pair of communication portslocated at the LCU. The nodes communicate with the

LCU over the LON/SLC as shown in Figure I-2.

Each field device node contains both the hardware and

software necessary to isolate and re-routecommunication in the event of a network wiring fault.

When a problem occurs somewhere within the networkwiring, the communication gateway located in the LCU

annunciates the fault, while the fault isolation circuitry inthe affected nodes isolates the section of the networkwhere the fault has occurred. Communication is

I – 3 95-8470



thereby ensured and will continue over the network.See Figure I-3.

A single open or short on the LON/SLC will not affectsystem communication between the field devices and

the gateway. System communication will continue untilthe wiring problem can be repaired.

MULTIPLE WIRING FAULTS

In the event of multiple wiring faults on the LON/SLC,the nodes between the faults will continue to function,

but the faults will prevent them from communicating withthe gateway. See Figure I-4. In this example, nodes 1

to 4 communicate using one gateway port (path A) andnodes 7 and 8 use the other gateway port (path B).

Nodes 5 and 6 are unable to report to the gatewaybecause they are isolated by the two wiring faults.

LON/SLC GROUND FAULT DETECTION AND LCUPROTECTION

The LCU contains an isolation module that checks theLON/SLC for ground faults. Should a ground fault bedetected, it is indicated by an LED on the isolation

module’s faceplate. The isolation module also ensurescommunication with the field devices even if there is aLON/SLC short circuit directly adjacent to the LCU.

FIELD DEVICES WITHOUT POWER

All Eagle Quantum field devices are designed so that a

“pass-through” circuit is created for the network wiringon a loss of power to the node. This ensures networkintegrity even when a node is down for service or has

been damaged. The Communication Gateway in theLCU will report powered-down nodes as “not-

communicating.”

IMPORTANT

Since it is impossible to predict where a network fault might occur or exactly what effect it will have

on actual system operation, it is important to diagnose and repair any fault as soon as possible after it is detected to ensure reliable system

operation.

Section IILocal Control Unit (LCU) and

Power Supplies

OVERVIEW

The Local Control Unit (LCU) is the “heart” of the Eagle

Quantum system. External host devices such as PLC’s

or DCS’s interface through the LCU, the fire detectionand releasing logic resides in the LCU, control of thereleasing, signaling, and annunciation outputs are

handled by the LCU, and the Local OperatingNetwork/Signaling Line Circuit (LON/SLC), through

which all field devices communicate, starts and ends itsloop at the LCU. Physically, the LCU consists of a threeslot rack style enclosure that houses the Communication

Gateway, Logic Controller, and Isolation Module. Thesethree modules plug into the backplane and are secured

with thumb screws. All external wiring is routed throughconduit entries at the bottom and sides of the unit. The

wiring terminals are protected by a removable cover.

The LCU can be installed in Class I, Division 2hazardous locations. Refer to Appendix A (FMRC) and

Appendix B (CSA) for details.

LOGIC CONTROLLER

The Eagle Quantum Logic Controller uses sevenmicroprocessors and parallel processing techniques toexecute the logic used for fire suppression. Its wealth

of logical operators allow for the easy development ofnearly any imaginable type of cross-zone monitoring,

voting, and timed operations that might be needed in afire suppression system. The Logic Controller supports

ANSI/NFPA 72 Class A, Style 7 communication with fielddevices.

COMMUNICATION GATEWAY

The Eagle Quantum Communication Gatewaycommunicates through two serial links for configuration

and monitoring. This allows for device configurationusing a comprehensive set of Det-Tronics authoredsoftware tools. The monitoring is provided to the

Operator Interface Station(s) (OIS) through Modbus orAllen-Bradley compatible protocols. The gateway also

provides four programmable relays that can be used toannunciate conditions being monitored by the devices

on the LON/SLC.

ISOLATION MODULE

The Isolation Module protects the integrity of the

LON/SLC wiring by isolating shorts and monitoring forground faults. It also provides electrical isolation for the

two serial communication ports between the gatewayand host devices.

OPTIONAL LCU VERSIONS

An optional EQ2101LCU is available with provisions for

two 24 vdc power inputs. Two reliable and independent24 vdc supplies, in accordance with ANSI/NFPA 72

section 1-5.2, must be supplied. If either of the suppliesis missing or a wiring problem occurs, a troublecondition will be annunciated.

Logic controllers can be added to the communicationnetwork to segment it into logical groups. Up to fourlogic controllers can be used on each network.

Auxiliary gateways can be added to provide additionalrelays or serial port connections to PLCs or DCSs. Up to

three auxiliary gateways can be added to the Quantumnetwork. Gateways located outside the LCU can be

turned off without disrupting LON/SLC communicationwith the LCU.

FEATURES

• Utilizes Modbus or Allen Bradley protocols

• Transformer isolation of network ports

• Four programmable relay outputs

• Three digit display and bar graph

• LEDs indicate relay status

• EMI/RFI hardened

DESCRIPTION

The Eagle Quantum Communication Gateway is used inconjunction with Det-Tronics software to configure the

system as well as to provide information on an ongoingbasis to external systems such as PLCs and DCSs. It

also provides local display and four programmablerelay outputs. In addition, the gateway provides a

heartbeat signal used to test for LON/SLC integrity, toprovide time and date information to field devices, andto monitor for the continued presence of all configured

field devices.

The gateway receives and stores the current status andprocess variable information from all devices on the

“Local Operating Network/Signaling Line Circuit”(LON/SLC) communication loop. It services all validrequests by Modbus RTU masters and/or Allen-Bradley

DF1 masters that are received through its two hostinterface serial ports. When acting as a Modbus RTU

master, the gateway will automatically transfer keyprocess variable and status information to a default or

user selected Modbus RTU slave address and registeroffset.



II–2

During normal operation the gateway produces aperiodic (250 millisecond) “heartbeat” signal on the

network, which is used by all field devices as a part oftheir network fault isolation routine. Every fourth“heartbeat” (1 second intervals) also includes a time

and date message that is used by the field devices forlogging calibration, alarm, and other events.

The gateway has sufficient non-volatile memory to store

configuration data for all networked field devices, whichis downloaded to the gateway from the OIS.

Faceplate Description

The faceplate provides four relay LEDs and one faultLED, a digital display, a bar graph, and a reset

pushbutton. See Figure II-1.

DIGITAL DISPLAY

The digital display is a three digit “seven segment”

display. During normal operating conditions, thedisplay indicates “000.” When a system event occurs

(alarm, fault or calibration) the display sequentially

shows the device address, followed by deviceidentification code, followed by device percent fullscale/fault code/calibrate signal.

Each indication is shown for 3/4 second, followed by a1/4 second delay before going to the next indication.

If more than one event should occur, the entire display

(digital display and bar graph) will track the status ofeach address where activity is occurring by sequencingthrough each event by order of address.

DEVICE ADDRESS

All three digits are on and the decimal point for each

digit is also on. Up to 250 addresses are available(displayed 0.0.1. to 2.5.0.).

DEVICE IDENTIFICATION CODE

See Table II-1 for device identification codes.

DEVICE PERCENT FULL SCALE/FAULT

CODE/CALIBRATE

The display follows the sensor input in percent of fullscale up to 100% full scale. A negative sign is used to

indicate a negative zero drift condition. See Table II-2for the status codes used by the gateway display.

A fault condition is indicated as “FXX,” with F indicating

that a fault has occurred and XX identifying the type offault that is detected.

If a detector is being calibrated, the display will show“CAL.”

BAR GRAPH

The 20 segment bar graph tracks the input signal fromthe sensor, providing a 0 to 100% full scale reading of

sensor input.

appropriate output(s) in response to the inputconditions. The logic controller supports ANSI/NFPA 72Class A, Style 7 communication with the field devices.

The logic controller uses fixed logic to control the

faceplate display and onboard alarm, trouble andsupervisory outputs per ANSI/NFPA 72.

The logic controller also has programmable logic, whichallows it to be customized to perform complex logic

operations including voting and timing. It alsocommunicates with the output modules located in the

LIOU, controlling system functions such as alarmsignaling, agent release and relay actuation.

The logic controller receives configuration informationthrough the gateway by means of its serial connection

to the operator interface system.

Faceplate Description

The faceplate has a key switch, two pushbutton

switches, and nine LEDs. See Figure II-2.

KEY SWITCH

The key switch on the front panel of the logic controller

is used to select from four operating modes — Normal,Acknowledge & Silence Enable, Reset or Isolate. The

key may be removed in the Normal or Isolate position.

NOTE Always rotate the key switch slowly when selecting operating modes.

Normal

In the normal mode, the controller’s program is runningand the outputs are enabled.

Acknowledge & Silence Enable

This mode enables the Acknowledge and Silence

pushbuttons.

NOTE

The Acknowledge and Silence pushbuttons are inhibited when the key switch is in the Normal

position.

Reset

In the reset mode, normal operation is inhibited and areset signal is sent to the LIOU and field output devices.

This mode is also used for programming. In theprogram mode, normal operation is inhibited. This is

the only mode that allows configuration information tobe downloaded to the logic controller from the gateway.

When the program mode is exited, configurationinformation is sent to the LIOU.

NOTE If the key switch is left in the RESET position for

more than a second or if the logic controller is in the Program mode, a Trouble condition will be indicated.

Section IIIEQ2100LIOU

Local Output Unit

OVERVIEW

The Local Output Unit (LIOU) consists of a six position

card rack. Available modules include:

Relay Module — four independently programmableunsupervised relay contacts.

Release Module — one release circuit and threesignaling circuits.

Signal Audible Module — four independentlyprogrammable signaling circuits.

These modules can be installed in the rack in anyposition. The Local Control Unit (LCU) automatically

reads the output module’s type and address on power-up. It is recommended that modules performing like

functions be inserted adjacent to each other to facilitateidentification and field wiring runs.

The assembly is controlled and supervised by the localcontrol unit (using an RS-485 serial communication link)

and must be mounted nearby (less than 20 feet). Up tofour LIOUs can be controlled by the LCU, adding a

maximum of 24 output modules to the system. Whenmultiple LIOUs are used, the last one in the chain must

be no more than 20 cable feet from the LCU.

NOTE

Input modules are not currently available for the

LIOU.

ENCLOSURE

The LIOU must be located in a controlled non-

hazardous area and must be mounted in a suitablemetallic nationally recognized test laboratory (NRTL)labeled NEMA rated enclosure.

FAULT LED AND RESET SWITCH

Each card in the LIOU is furnished with a yellow fault

LED and a Reset switch. During Normal operation, the

LED is off. The yellow LED turns on when the Resetbutton is pressed or a fault occurs. Pressing the Reset

button resets the microprocessor on the card, causing itto re-initialize. At this time, the Trouble light on the LCU

is also turned on.

If the Reset button is pressed with an output energized,the output is de-energized until the event that triggeredthe output re-occurs. (Outputs are “event driven.”)

The yellow LED also turns on if:

– An output fault occurs (signal audible and agent

release modules only). The LED is reset automaticallywhen the fault clears.

– A microprocessor fault occurs.

– The card is not configured.

– A loss of communication with the LCU occurs (RS-

485). If an output is on during a loss ofcommunication, the output will remain in the currentstate and can only be reset using the reset switch on

the Logic Controller.

trouble condition. It is intended for use with a third partypower supply.

The EQ2200IDCSC Initiating Device Circuit Short Circuit(IDCSC) provides two supervised digital inputs formonitoring the system for shorts circuits. The IDCSC

supports ANSI/NFPA 72 Class B Style C (3 state,open/short circuit) supervised input circuits.

Inputs

Each IDC accepts two dry contact inputs for use withdevices such as relays, pushbuttons, key switches, etc.

The IDC supports ANSI/NFPA 72 Class B Style Bsupervised input circuits (Class B Style C for IDCSC).

Each circuit requires its own end of line (EOL) resistorfor monitoring circuit continuity. Nominal resistance of

the resistor is 10 k ohms.

Inputs are software selectable in EagleVision NT toactuate the alarm, trouble, or supervisory relays on theLCU.

The output of the device is a status message that is sent

to the gateway and logic controller in the Local ControlUnit along the LON/SLC. System response to the

message is determined at the time of configuration. TheIDC supports ANSI/NFPA 72 Class A, Style 7communication with the LCU.

A Standard Periodic Report (SPR) is sent to the gateway

at the rate determined at the time of configuration.When programmed for response to a fire alarmcondition, a special Acknowledged Exception Report

(AER) is immediately sent to the Logic Controller.

Addressability

Device identification is accomplished by setting

switches on an eight position DIP switch (valid addressrange is 5 to 250).

Status LEDs

Three LEDs are located at the center of the

communication module circuit board and are visiblewhen the cover is removed.

The green LED serves as a power-on indicator and isthe only LED illuminated during normal operation (nofaults or alarms occurring).

The red LED is used to indicate an alarm or fault

condition. The flashing rate of the red LED indicates thefollowing conditions:

On steady = one of the inputs is activeBlinking = fault condition such as an open input

circuit or not configured.

The amber LED is provided for factory diagnosticpurposes and is not used by the customer. Illumination

of the amber LED normally indicates a failure in thecommunication chip. Replacement of the communicationmodule circuit board is required.

capability.

Detector status is indicated by red LEDs visible throughthe detector’s viewing window. Table IV-1 indicates the

condition of the LEDs for each detector status.



IV-2

Output

The output of the device is a status message that is sent

to the gateway and logic controller in the Local ControlUnit along the communication loop. System response

to the message is determined at the time ofconfiguration. The UV detector supports ANSI/NFPA 72Class A, Style 7 communication with the LCU.

A Standard Periodic Report (SPR) is sent to the gateway

at the rate determined at the time of configuration.When programmed for response to a fire alarm

condition, a special Acknowledged Exception Report(AER) is immediately sent to the Logic Controller.

Addressability

Device identification is accomplished by settingswitches on an eight position DIP switch (valid address

range is 5 to 250).

Alarm Log

Each detector maintains an alarm log in non-volatile

memory. The time and date for the last eight alarms arelogged.

Terminal Wiring Board

All external wiring is connected to screw terminalconnectors on the terminal wiring board located inside

the detector housing.

Enclosure

The explosion-proof NEMA/Type 4X enclosure isdesigned for use in a variety of hazardous locations.

SOFTWARE SELECTABLE OPTIONS

The following software selectable options are availablethrough a PC running Det-Tronics configuration

software.

Operating Mode

The operating mode determines the type of logic that

the UV flame detector will use for processing fire signals(either standard or arc rejection).

ARC REJECTION MODE

The arc rejection mode (recommended) enables thedetector to prevent nuisance fire alarms caused by UV

from short-duration electrical arcs or electrostaticdischarge, while maintaining the ability to reliably detect

the UV given off by a flame. The arc rejection mode isnot recommended unless these false alarm sources arepresent within the application to be protected. Typical

applications that benefit from arc rejection logic includeelectrostatic coating processes and uncontrolled

environments where transient UV sources can bepresent, such as many typical outdoor applications.

STANDARD MODE

In the standard processing mode, the detector output(measured in counts per second) is compared to the

fire threshold (the “sensitivity” setting as describedbelow). If the radiant energy level from the fire exceeds

the selected alarm threshold level, the time delaybegins (if a time delay is selected). If the radiant energy

level from the fire remains above the selected sensitivitylevel for the duration of the time delay, the fire alarmoutput is activated. In every application, it is crucial to

ensure that the radiant ultraviolet energy level from theexpected fire at the required distance from the detector

will exceed the selected sensitivity level.

Standard signal processing is recommended forcontrolled indoor applications only.

The arc rejection algorithm examines the radiant energylevel detected within a specified unit of time (timed

gate). Detector output is determined by three variables:— sensitivity level

— gate length— number of consecutive gates required.

Table IV–1—EQ2200UV Detector Status/Indications



IV-3 95-8470

Different combinations of these variables allow forvarious levels of transient arc rejection capability. There

are four arc rejection levels (very high, high, medium,and low) that are selectable for each detector throughthe PC. Refer to Table IV-2.

The proper arc rejection setting for a given application

must be determined through testing. For indoorapplications with known electrostatic energy fields

within 15 feet of the detector, an arc rejection setting of“very high” or “high” is typical. For outdoorapplications, “medium” or “low” arc rejection settings

are typical.

It is recommended that each detector be thoroughlytested at the programmed arc rejection setting within

the ambient conditions that will be present duringnormal operation. This will help to ensure that theselected arc rejection setting is proper for the

application.

Sensitivity

Whether the Standard or Arc Rejection mode isselected, the sensitivity setting must always be

programmed. The selected sensitivity level determinesthe fire alarm threshold setpoint. The higher thesensitivity level, the greater the detection range, but the

possibility of false alarms will be increased. Foursensitivity levels are selectable. Refer to Table IV-3.

The sensitivity setting must be appropriate for the

anticipated fire size at the required distance from thedetector.

Time Delay

Arc rejection mode — If the fire signal meets the

programmed arc rejection requirements, the time delaybegins. A fire output is generated if the fire signal

continues for the duration of the time delay.

Standard mode — A fire output is generated only if the

fire signal exceeds the sensitivity setting for the entire

duration of the programmed time delay.

Automatic or Manual oi

The oi system uses an internally generated UV testsignal to determine the relative condition of the detector

and its optical surfaces.

If automatic oi testing is selected, the oi test isautomatically performed once every minute. The

automatic oi test does not generate an alarm output orinterfere with normal detector operation.

The manual oi test is initiated using a button on thepoint display screen at the PC. The manual oi test can

be used in addition to automatic oi to verify correctsystem operation.

Fire Output Latching

When latching operation is selected, the fire alarmsignal is cleared by removing input power for a

minimum of 0.1 second.

Fault Latching

If the fault output is set for latching, the fault will not

clear until it is corrected and the unit is reset. If a fireoccurs, the unit will indicate a fire, over-riding the fault

condition, i.e., the fault signal will clear if not latched. Ifa fault is stil l present after the fire has beenextinguished, the unit will again indicate a fault until the

problem has been corrected and the unit is reset.

EQ2200UVHT HIGH TEMPERATUREUV FLAME DETECTOR

DESCRIPTION

The EQ2200UVHT UV Flame Detector provides UV

flame protection in continuous duty high temperatureapplications, such as turbine compartments,

enclosures, generator rooms, etc. where ambienttemperatures can continuously exceed +75°C (+167°F).

The EQ2200UVHT is an electronic module assemblythat is used in conjunction with a high temperature rated

C7050B UV detector (with DE1888K3 high temperaturerated UV sensor tube). The two devices are mounted in

separate explosion-proof, watertight enclosures.

The UV detector is rated for continuous duty in

environments up to +125°C (+257°F). The electronic

module is rated up to +75°C (+167°F).

NOTE

The electronic module cannot be located in the high temperature area.

The UV detector and electronic module assembly canbe separated up to 165 feet (50 meters) using high

temperature rated 4 core shielded cable.

NOTE In accordance with NFPA 72, the maximum separation distance is 20 feet (6 meters) using

conduit or equivalent protection against mechanical damage.

LED

Detector status is indicated by a red LED that is visible

through the viewing window on the cover of theelectronic module junction box.

Refer to the “EQ2200UV UV Flame Detector” sectionabove for a description of features, operating

characteristics and software selectable options of Det-Tronics Eagle Quantum UV detectors.

EQ2200UVIR FLAME DETECTOR

DESCRIPTION

The EQ2200UVIR Series Flame Detector is designed toprovide reliable fire protection in applications where the

use of either ultraviolet (UV) or infrared (IR) detectorsalone can result in false alarms. When used alone, a UV

detector can respond to sources of ultraviolet radiation

besides fire, such as lightning, x-rays or arc welding.Likewise, an IR detector can respond to various hotobjects, such as flickering or chopped radiation from

electric heaters or exhaust manifolds. Themicroprocessor based EQ2200UVIR combines both aUV and a single frequency IR sensor in a single

detector and requires simultaneous response of bothsensors to generate a fire alarm. These two detecting

elements monitor different portions of the radiationspectrum and have virtually no common sources of

false alarms. This enables the detector to respond to areal fire while ignoring potential false alarm sourcessuch as arc welding, x-rays, or hot vibrating objects.

Microprocessor based circuitry located inside the

detector junction box continuously monitors the twosensors, evaluating the signal(s) with fire and fault

algorithms to determine the current status of thedetector. When both sensors simultaneously detect thepresence of fire, the microprocessor generates a fire

signal, which is immediately sent over the LON/SLC tothe logic controller in the Local Control Unit (LCU). The

LEDs, visible through the UV sensor viewing window,are also immediately il luminated. In addition, a

watchdog timer assures that the detector’s operatingprogram is running properly.

Detector Output

The output of the device is a status message that is sentto the gateway and logic controller in the LCU along thecommunication loop. System response to the message

is determined at the time of configuration. The detectorsupports ANSI/NFPA 72 Class A, Style 7 communication

with the LCU.

Status Conditions

Detector status conditions include normal operation,fire, fault, UV only, and IR only. A fire alarm signal isgenerated when both UV and IR sensors are active.

The fire alarm status has the highest priority and willoverride a fault condition.

Automatic Diagnostics

The microprocessor based detector is equipped withadvanced fault detection and diagnostic capabilities.

The LED indicators on the UV sensor module providethe user with visual annunciation of the problem area.

In addition, the point display screen at the OIS providesa variety of information regarding detector status as well

as the actual UV and IR signal levels present at thedetector. Refer to Table IV-5 for a list of statusconditions.

SOFTWARE SELECTABLE OPTIONS

The following options are selectable through a PC

running Det-Tronics configuration software:

Processing Mode

The UV portion of the detector offers a choice of two

different types of logic that can be used for processing

fire signals — either standard or arc rejection.

ARC REJECTION MODE

The arc rejection mode (recommended) enables thedetector to prevent nuisance fire alarms caused by

short-duration electrical arcs or electrostatic discharge,while maintaining the ability to reliably detect a flame.

The arc rejection mode is not recommended unlessthese false alarm sources are present within the

application to be protected. Typical applications thatbenefit from arc rejection logic include any uncontrolledenvironments where transient radiation sources can be

present, such as many typical outdoor applications.

The arc rejection algorithm examines the radiant energylevel detected within a specified unit of time (timed

gate). The output of the detector is determined by threevariables:— sensitivity level

— gate length— number of consecutive gates required.

Different combinations of these variables allow for

various levels of transient arc rejection capability. Thereare two arc rejection levels (medium and high) that are

selectable for the detector through the OIS. The properarc rejection setting for a given application must bedetermined through testing.

Table IV–5—Status Conditions of UV/IR Detector



It is recommended that each detector be thoroughlytested at the programmed arc rejection setting within

the ambient conditions that will be present duringnormal operation. This will help to ensure that theselected arc rejection setting is proper for the

application.

STANDARD MODE

In the standard processing mode, the UV sensor output(measured in counts per second) is compared to thefire threshold (the “sensitivity” setting as described

below). If the radiant energy level from the fire exceedsthe selected alarm threshold level, the time delay

begins (if a time delay is selected). If the radiant energylevel from the fire remains above the selected sensitivity

level for the duration of the time delay, a fire alarmsignal is generated. In every application, it is crucial toensure that the radiant energy level from the expected

fire at the required distance from the detector willexceed the selected sensitivity level.

Standard signal processing is recommended forcontrolled indoor applications only.

Sensitivity

Whether Arc Rejection or Standard mode is selected,

the sensitivity setting must always be programmed. Theselected sensitivity level determines the fire alarm

threshold setpoint. The higher the sensitivity level, thegreater the detection range, but the possibility of false

alarms will be increased. Four sensitivity levels areselectable. (Sensitivity levels for UV and IR are selectedseparately.)

The sensitivity setting must be appropriate for the

anticipated fire size at the required distance from thedetector. Refer to the “Specifications” section of this

manual for additional information.

Time Delay

A time delay from 0 to 7 seconds is selectable.

STANDARD MODE

A fire output is generated only if the fire signal exceedsthe sensitivity setting for the entire duration of the

programmed time delay.

ARC REJECTION MODE

If the fire signal meets the programmed arc rejectionrequirements, the time delay begins. A fire output isgenerated if the fire signal continues for the duration of

the time delay.

Automatic or Manual oi

The EQ2200UVIR is equipped with the Optical Integrity(oi) feature. The oi test is performed on both the UV

and IR sensors to check the cleanliness of the detectoroptics, as well as the proper functioning of the sensors

and electronic components of the detector. If aproblem should occur, it is quickly detected.

The detector is user programmable (from a PC runningDet-Tronics configuration software) for automatic oi

testing. If automatic testing is selected, the oi test isautomatically performed on each sensor. The rate for

the UV sensor test is once per minute. The rate for theIR sensor is field selectable from once a minute to onceevery four hours. If a fault is detected, a trouble signal

is sent to the LCU over the LON/SLC. A fault conditionis indicated at the logic controller and the gateway and

also by the LEDs on the detector’s UV sensor. Theautomatic oi test does not generate an alarm output or

interfere with normal detector operation.

The manual oi test is initiated using a button on thepoint display screen at the OIS. A successful test issignaled by the OIS. The manual oi test can be used in

addition to automatic oi to verify correct detectoroperation.

NOTE The manual oi test does not generate an alarm

output or actuate any system outputs.

Fire Output Latching

When latching operation is selected, the fire alarm

signal is present until cleared by a reset command fromthe PC.

EQ2200DCU AND EQ2200DCUEX

DIGITAL COMMUNICATION UNIT

DESCRIPTION

The EQ2200 Series Digital Communication Unit (DCU)digitizes a 4 to 20 ma analog signal and transmits the

value as the process variable portion of its Standard

Periodic Report (SPR) to the Communication Gatewaylocated in the LCU. All circuitry is housed in a single

explosion-proof/watertight enclosure for use in the areaof detection.

Designed for use with the Eagle Quantum system, the

DCU provides a unique technique for detecting andisolating opens or shorts in the Local OperatingNetwork/Signaling Line Circuit (LON/SLC) wiring. This

IV-7 95-8470



fault isolation method allows for communication integrityin the event of a single wiring fault in the LON/SLC

wiring.

The DCU is approved for use with a variety of Detector

Electronics sensors including catalytic combustible gassensors, the PointWatch IR gas detector, as well as

electrochemical sensors (hydrogen sulfide, carbonmonoxide, chlorine, sulfur dioxide, and nitrogen

dioxide). It will also accept any sensor with a linear 4 to20 ma output signal and allows for one person non-intrusive calibration.

Inputs

The DCU features one 4 to 20 ma non-isolated input,

with an input impedance of 200 ohms in series with aprotection diode. (When used with a Det-Tronicscatalytic combustible gas sensor, a separate transmitter

board converts the millivolt output to a 4 to 20 masignal.) The DCU also monitors its 24 vdc supply

voltage and reports to the PC when requested.

Output

The Standard Periodic Report (SPR) is sent to thegateway at the rate determined at the time ofconfiguration (from one to ten seconds).

Calibration

A magnetic reed switch, located on the terminal board,

enables calibration of the sensor without opening theenclosure. The switch is activated by placing acalibration magnet at a specified location on the side of

the enclosure. Once the calibration mode has beenentered, the DCU steps the user through the process.

For details, refer to the “Calibration” section of thismanual.

Addressability

Device identification is accomplished by settingswitches on an eight position DIP switch (valid address

range is 5 to 250).

Status LEDs

Three LEDs are located at the center of the

communication module circuit board and are visiblethrough the window on the enclosure cover.

The green LED serves as a power-on indicator and is

illuminated whenever power is applied. During normaloperation, only the green LED is illuminated.

The red LED is used to indicate a calibration, power-up,fault or alarm condition. The flashing rate of the red

LED indicates the following conditions:

Power-up = Pulsed at a 0.5 Hz rateCalibration = Pulsed at a 1 Hz rate or on steady

Fault = Pulsed at a 4 Hz rateAlarm = Illuminated continuously.

NOTE If the communication module has not been configured, the red LED blinks at the 4 Hz rate.

The amber LED is provided for factory diagnosticpurposes and is not used in the system. Illumination ofthe amber LED normally indicates a failure in the

communication chip. Replacement of thecommunication module circuit board is required.

Calibration Log

The DCU keeps a calibration log in non-volatile memory

that can be used by the operator to evaluate theremaining life of some sensors. This log includes thezero, span, date and time for each successful

calibration. An aborted calibration is indicated by zerosin the zero and span values. The calibration log iscleared when the sensor replacement switch is pressed

and the calibration is successfully completed.

The initial calibration is logged in position one, where itremains for the life of the sensor. If more than 8

calibrations are performed without the sensorreplacement switch being pressed, the newest

calibration data will replace the second oldest so thatthe initial calibration data can be saved. The oldcalibration data will be lost. This feature enables sensor

sensitivity trending to aid in maintenance ortroubleshooting.

The analog value for the sensor is represented in raw

analog to digital counts 0 to 4095, where 0 represents 0ma and 4095 represents 24 ma.

Alarm Log

A log of low and high alarms is stored in each DCU.

Time, date and alarm type are logged for each alarmevent. A maximum of eight events can be stored. Ifmore than eight events are logged, the oldest event willbe overwritten.

IV-8



Enclosure

The explosion-proof, watertight NEMA/Type 4X

enclosure is designed for use in a variety of hazardouslocations. The cover is furnished with a window to allow

the operator to view the three status indicator LEDs onthe communication module PC board.


All external wiring is connected to screw terminalconnectors on the terminal wiring board located inside

the junction box.

EQ2500ARM AGENT RELEASEMODULE

DESCRIPTION

The EQ2500ARM Series Agent Release Module (ARM)is located on the LON/SLC and provides agent releasecapability for the Eagle Quantum system. The device is

controlled by programmable logic in the LogicController and can be programmed for “Single,” “Cross”

or “Counting” Zone Style initiation. Optional time delay,abort and manual release sequences allow the output to

be programmed for use in unique applications.

The Agent Release Module can monitor and control two

output devices (rated for 24 vdc), which areprogrammed and energized together. The release

circuits are compatible with a variety of solenoid orinitiator (squib) based suppression systems.

EQ2400NE NETWORK EXTENDER

DESCRIPTION

The EQ2400NE Series Network Extender expands the

capabilities of the Eagle Quantum system by allowingadditional nodes as well as additional wiring to beadded to the LON/SLC (communication loop). Without a

network extender, the communication network is limitedto 60 nodes on a 2000 meter loop. Each networkextender, however, increases the capacity of the loop

by up to 40 nodes and 2000 meters of wiring, up to amaximum of 244 field nodes and 10,000 meters of

wiring.

Network extender circuitry supports communication inboth directions. If a network wiring fault should occur,

uninterrupted communication can continue in theopposite direction.

LEDs

The network extender’s electronic module is furnishedwith three LEDs (one green and two yellow) for

indicating device status.

IV-10



The green LED indicates that power is applied andflashes to indicate that messages are being transferred

over the network.

The two yellow LEDs correspond to the two

communication transceivers and are illuminated toindicate that an internal fault has been detected.

Enclosure

The network extender’s electronic circuitry is mountedinside an explosion-proof, water-tight enclosure for

installation in hazardous locations. The enclosure isavailable with up to six 3/4 inch NPT or 25 mm conduit

entries.

GENERAL APPLICATION INFORMATION

System Capacity

The basic Eagle Quantum system supports a

communication loop consisting of up to 60 detection

nodes and up to 2000 meters of connecting wiring.Adding a network extender to the loop allows it to beexpanded by up to 40 nodes with an additional 2000meters of wiring. Up to 6 network extenders can be

utilized in a single system, supporting up to 244 fieldnodes and up to 10,000 meters of wiring.

To ensure optimum performance, it is important to

distribute the network extenders along the loop so thatthere are no more than 40 detection nodes or 2000

meters of wiring on either side of a network extender.See Figure IV-1.

Response Time vs. System Size

When designing a system, it is important to realize thatincreasing the number of nodes on the communication

loop can result in an increase in the amount of timerequired for a status change message from a detection

node to reach the host computer.

The gateway requires a finite length of time to processeach bit of information that is transferred along thecommunication network. As the number of nodes

increases, so does the amount of data that is being

processed as well as the time required for processingthe data. As a result, the update time for each nodeshould be increased to accommodate the extra traffic

for a large system (one second minimum for each 50nodes).

If the fastest possible communication response time isan important criteria for a large system, it is

recommended that the number of nodes on anindividual loop be kept as small as practical. Considerusing multiple loops with fewer nodes per loop rather

than one large loop.

Section VDetector Application

Information

UV DETECTORS

In applying any type of sensing device as a fire

detector, it is important to know of any conditions that

can prevent the device from responding to a fire, andalso to know what other sources besides fire will causethe device to respond.

WINDOWS

Glass and plexiglas windows significantly attenuate UVradiation and must not be located between the detector

and a potential flame source. If the window cannot beeliminated or the detector location changed, contact

Detector Electronics for recommendations regardingwindow materials that will not attenuate UV radiation.

OBSTRUCTIONS

For an ultraviolet detector, dust, dirt and other films, UVabsorbing gases or vapors as well as physical

obstructions must not be allowed to come between thedetector and the protected hazard (see Table V-1).

SMOKE

Smoke will absorb UV radiation, and if accumulations ofdense smoke can be expected to precede the

presence of flame, then ultraviolet detectors that areused in enclosed areas should be mounted on the wall

approximately 3 feet (1 meter) from the ceiling wherethe accumulation of smoke is reduced.

ARC WELDING

Electric arc welding is a source of intense ultravioletradiation, and care must be taken to ensure that arc

welding is not performed in the protected area withoutsecuring the fire detection system. UV radiation fromarc welding readily scatters and can deflect across

significant distances, even when direct obstructionsexist. Any open door or window can allow nuisance UV

radiation from arc welding to enter an enclosed area.

When x-rays or radioactive substances are present inthe area being protected, the UV system must bedisabled until those sources are removed.

COMMON ENVIRONMENTAL CONDITIONS

The detector is not affected by environmental conditions

such as wind, rain or extremes of temperature and

pressure. It is also insensitive to the ultravioletcomponent of solar radiation.

UV radiation generated by periodic lightning or sparksin the area can be effectively ignored by the detector

using the arc rejection feature or time delay.

UV detectors should not be positioned so that their coneof vision can scan the horizon. Rather, they should be

directed down over the designated hazardous area toreduce the likelihood of picking up UV radiation fromdistant sources.

The following is a partial list of compounds that exhibit

significant UV absorption characteristics. These are also

usually hazardous vapors. While generally of little

consequence in small amounts, these gases can restrict

UV detection if they are in the atmosphere in heavy

concentrations. It should also be determined whether or

not large amounts of these gases may be released as aresult of a fire-causing occurrence.

Acetaldehyde Methyl Methacrylate

Acetone Alpha-Methylstyrene

Acrylonitrile Naphthalene

Ethyl Acrylate Nitroethane

Methyl Acrylate Nitrobenzene

Ethanol Nitromethane

Ammonia 1-Nitropropane

Aniline 2-Nitropropane

Benzene 2-Pentanone

Butylamine PyridineChlorobenzene Hydrogen Sulfide

1-Chloro-1-Nitropropane Styrene

Chloroprene Tetrachloroethylene

Cumene Toluene

Cyclopentadiene Trichloroethylene

O-Dichlorobenzene Vinyl Toluene

P-Dichlorobenzene Xylene

If UV-absorbing gases may be a factor in a given

application, precautionary measures should be taken.

Detectors can be placed closer to the potential hazard

area, and/or the sensitivity of the detection system can be

increased. Contact the factory for further details.

Substances such as methane, propane, butane, hexane,camphor and octane are not UV absorbing.

Absorption of infrared radiation in the range of 4.2 to 4.7

microns is not a significant problem with most organic

vapors, with the exception of those compounds that have

triple bonds such as acetylene, nitriles, silane, or

isocyanates. Carbon dioxide concentrations higher than

normally present in the atmosphere can also cause

substantial loss of fire detection sensitivity.

Table V-1—UV and IR Absorbing Gases and Vapors



V-2

UV DETECTOR POSITIONING

Detectors should be positioned to provide the best

unobstructed view of the area to be protected. Thefollowing factors should be taken into consideration:

• Identify all high risk fire ignition sources.

• Be sure that enough detectors are used to adequatelycover the hazardous area.

• For fastest response time, locate the detector as closeas possible to the anticipated fire source. The central

axis of the detector’s cone of vision provides thehighest sensitivity.

• Be sure that the unit is easily accessible for cleaningand other periodic servicing.

• Particular attention should be paid to potential falsealarm sources within the cone of vision of the detector.

• For outdoor applications, the detector should beaimed downward at least 10 to 20 degrees to prevent

it from scanning the horizon. This minimizes response

to distant UV sources outside the protected area. SeeFigure 1.

• Dense fog, rain or ice will absorb UV radiation and

reduce the sensitivity of the detector.

• If smoke is expected before flame, it is recommended

that smoke or other additional detectors be used inconjunction with the UV detector.

If possible, fire tests should be conducted to verifycorrect detector positioning and coverage.

UV/IR DETECTORS

FALSE ALARM SOURCES

UV: The UV sensor is insensitive to the ultraviolet

component of solar radiation. However, it willrespond to sources of UV besides fire, such as

electric arc welding, lightning, high voltage corona,x-rays and gamma radiation.

IR: The detector has been designed to ignore steadystate infrared sources that do not have a flicker

frequency characteristic of a fire, however, it shouldbe noted that if these steady state infrared sources

are hot enough to emit adequate amounts ofinfrared radiation in the response range of the IR

sensor and if this radiation becomes interruptedfrom the view of the detector in a patterncharacteristic of a flickering flame, the IR sensor

can respond.

Any object having a temperature greater than 0°Kelvin (–273°C) emits infrared radiation. The hotter

the object, the greater the intensity of the emittedradiation. The closer the infrared source is to thedetector, the greater the potential for a false alarm.

The IR sensor can respond to IR radiation sourcesthat can meet the amplitude and flicker

requirements of the detector such as vibrating hotobjects.

Although the detector is designed to reduce false

actuations, certain combinations of ambientradiation must be avoided. For example, if IRradiation with an intensity that exceeds the fire

threshold of the IR sensor should reach the detectoras a flickering signal, and if at the same time an

electric arc welding signal also reaches thedetector, an alarm output will be generated.

NOTE Radiation generated by false alarm sources such

as periodic lightning or sparks in the area can be effectively ignored by the detector using the arc rejection feature or time delay.

Arc Welding

Electric arc welding is a source of intense ultraviolet

radiation. UV radiation from arc welding readily scattersand can deflect across significant distances, even when

direct obstructions exist. Any open door or window canallow nuisance UV radiation from arc welding to enter

an enclosed area.

B1974

Figure 1—Detector Orientation Relative to Horizon



The UV/IR detector does not respond to arc weldingbeyond 10 feet from the detector. However, a UV only

signal will be generated in response to the intense UVradiation generated by the arc welding, and atdistances closer than 10 feet the heated metal from the

welding can become a false alarm source for the IRsensor.

FACTORS INHIBITING DETECTOR RESPONSE

Windows

Glass and Plexiglas windows significantly attenuateradiation and must not be located between the detector

and a potential flame source. If the window cannot beeliminated or the detector location changed, contact

Detector Electronics for recommendations regardingwindow materials that will not attenuate radiation.

Obstructions

Radiation must be able to reach the detector in order for

it to respond. Care must be taken to keep physicalobstructions out of the line of view of the detector. Inaddition, UV or IR absorbing gases or vapors must not

be allowed to accumulate between the detector and theprotected hazard. See Table V-1 for a list of thesesubstances.

Smoke

Smoke will absorb radiation. If accumulations of dense

smoke can be expected to precede the presence of aflame, then detectors that are used in enclosed areasshould be mounted on the wall approximately 3 feet (1

meter) from the ceiling where the accumulation ofsmoke is reduced.

Detector Viewing Windows

It is important to keep the detector viewing windows asfree of contaminants as possible in order to maintain

maximum sensitivity. Commonly encounteredsubstances that can significantly attenuate UV and/or IR

radiation include, but are certainly not limited to, thefollowing:

Silicones

Oils and greasesIce buildupDust and dirt buildup

Paint overspray.

UV/IR DETECTOR POSITIONING

IMPORTANT

Detectors should not be positioned so that their cone of vision can scan the horizon. Rather, they should be directed down over the designated

hazardous area to reduce the likelihood of picking up radiation from distant sources. See Figure 1.

Detectors should be located in positions best suited forcovering the area to be protected. Whenever practical,they should be placed where they will be easily

accessible for cleaning and other periodic servicing.Particular attention should also be paid to potential false

alarm sources within the cone of vision of the detector,such as distant arc welding, or the rotating blades of a

fan or surface vibration of an IR source, which couldallow a flickering IR signal to reach the detector. Rainor ice can absorb radiation, which can reduce the

capability of the detector. For outdoor applications, aimthe detector downward to minimize the buildup of water

or ice on the detector viewing windows and to prevent

the cone of vision from scanning the horizon. Thisminimizes response to distant radiation sources outsidethe protected area.

GAS DETECTOR POSITIONING

The sensor must be properly located to enable it to

provide maximum protection. The formula fordetermining the most effective number and placementof sensors varies depending on the conditions at the job

site. The individual performing the installation must relyon experience and common sense to determine the

quantity of sensors and the best sensor locations toadequately protect the area.

The following factors should be considered for everyinstallation:

1. What kind of gas is to be detected? If it is lighter

than air (acetylene, hydrogen, methane, etc.), placethe sensor above the potential source. Place the

sensor close to the floor for gases that are heavierthan air (benzene, butane, butylene, propane,hexane, pentane, etc.) or for vapors resulting from

flammable liquid spills. However, note that aircurrents can cause a gas that is heavier than air to

rise. In addition, if the gas is hotter than ambientair, it could also rise.

2. How rapidly will the gas diffuse into the air? Selecta location for the sensor as close as practical to the

anticipated source of a gas leak.

V-3 95-8470



V-4

3. Ventilation characteristics of the immediate areamust also be considered. Movement of air will

cause gas to accumulate more heavily in one areathan another. The sensor should be placed in thearea where the most concentrated accumulation of

gas is anticipated. Also consider the fact that manyventilation systems do not operate continuously.

4. The sensor should be pointed down to prevent the

buildup of moisture or contaminants on the filter andto ensure proper operation. For PointWatch, refer toinstruction manual 95-8440.

5. The sensor must be accessible for testing and

calibration. The use of the Sensor Separation Kitwill be required in some installations.

6. Catalytic sensors should be located where they aresafe from potential sources of contamination that

can poison the sensing element.

7. Exposure to excessive heat or vibration can result in

premature failure of any electronic device andshould be avoided if possible. Shielding the devicefrom intense sunlight will reduce solar heating and

can increase the life of the unit.

For additional information on determining quantity and

placement for sensors in a specific application, refer toInstrument Society of America (ISA) Transaction Volume

20, Number 2, titled “The Use of Combustible Detectorsin Protecting Facilities from Flammable Hazards.”

CATALYTIC GAS SENSORS

CAUTION Exposure to a high level of gas can have an

adverse effect on the sensitivity of catalytic sensing elements. If the level of gas at the sensor should

reach 100% LFL, it is important that it be tested and recalibrated if required. In some cases, it may

be necessary to replace the sensor.

If an over-range condition should occur, the user

must exercise caution, since a highly explosive condition could exist. The hazardous area should

be checked with a portable detection instrument to determine the actual level of combustible gas

present.

For best calibration results, allow a new sensor tooperate for several hours to ensure a stable output

before performing calibration. For the highest degree ofaccuracy, perform a second calibration after 24 hours.

When a sensor is exposed to a different or newenvironment, calibration should be checked frequently

to determine the proper interval between periodiccalibrations.

Before performing calibration, the operator shouldexamine the sensor filter (flame arrester) to be sure that

it is not missing or damaged. If the filter is defective ormissing, it must be replaced. In some cases, an

exposed sensing element can act as an ignition source.It should also be noted that a dirty cover cansignificantly reduce the sensitivity of the sensor.

CATALYTIC SENSOR OPERATION

The sensing element used in the combustible gas

sensor consists of a pair of elements. One is an activecatalytic sensing element, and the other is inactive andacts as a temperature compensating reference element.

Both elements are composed of a wire coil encased inceramic. The active element has a catalytic coating

applied to its surface, however, the reference element is

glazed so that it does not react to the presence of acombustible gas/air mixture. The pair is computermatched to have the same electrical resistance.

In the presence of a combustible gas/air mixture, theresistance of the active sensing element increases in

proportion to the concentration of gas at the sensor.The change in resistance of the active sensing element,

relative to that of the reference element, is used todetermine the actual level of combustible gas present at

the sensor.

Both elements operate at a high temperature and are

enclosed by a porous stainless steel cup (flamearrester). See Figure V-2. This cup allows the diffusion

of gas to and from the sensing element, but preventsthe ignition of the atmosphere outside the sensor should

the combustible gas concentration exceed its LFL.

A barrier is placed between the element pair to prevent

thermal interaction and to prevent the transfer ofcatalytic material from the active element to the surface

of the reference element.

All catalytic type sensors require oxygen to detectcombustible gases. The sensor response will decreaseif enough combustible gas displaces the normal oxygen

present in air. The sensor should not be used where theoxygen level is less than 10%. See Figure V-3.

Figure V-4 shows the response of a typical sensor to

various levels of combustible gas. Note that a reading of40% LFL will be given at 2.0% methane (40% LFL) and



also at 80.0% methane, well above the upper flammablelimit of methane. Although gas levels above the upper

flammable limit will not propagate a flame, it stands toreason that somewhere between the leak and clear airthere will be a flammable mixture.

CAUTION It is possible for the display to drop to a low % LFL

reading after going into high alarm and still have an

unsafe level of combustible gas present.Therefore, precautions should be taken to ensure that the combustible gas has been cleared before

classifying the area as safe.

SENSITIVITY LOSS IN CATALYTIC COMBUSTIBLEGAS SENSORS

There are a variety of factors that can cause a decrease

in the sensitivity of catalytic type combustible gassensors. Interfering or contaminating substances that

can adversely affect the response of the sensor tocombustible gases are as follows:

A. Materials that can clog the pores of the sintered

metal flame arrestor and reduce the gas diffusionrate to the sensor are:

1. Dirt and oil.

A dust cover should be installed to protect the

flame arrester whenever these conditions exist.

The dust cover can be cleaned as part of routinemaintenance. This can be accomplished using

an organic solvent and an ultrasonic bath.

2. Corrosive products.

This occurs when substances such as Cl2(Chlorine) or HCl are present. A dust coverprovides some protection. The dust cover

should be replaced as part of routinemaintenance.

3. Flame arrester clogged as a result of paintingor house cleaning.

The routine maintenance procedure should

include covering the sensor with a plastic bagwhen painting or cleaning. The bag should be

removed as soon as possible when theprocedure is complete.

4. Polymer formation in the flame arrester.

This can occur where monomer vapors such as1-3 butadiene, styrene, isoprene, etc. are

present.

B. Substances that cover or tie up the active sites on

the catalytic surface of the active sensing element.

This occurs in the presence of volatile metalorganics, gases, or vapors of hydrides, and volatile

compounds containing phosphorous, boron,silicone, etc.

Examples:RTV silicone sealants

Silicone oils and greases

Tetraethyl leadPhosphineDiborane

SilaneTrimethyl chlorsilaneHydrogen fluoride

C. Materials that remove the catalytic metals from theactive element of the sensor.

Some substances react with the catalytic metalforming a volatile compound. This erodes the metal

from the surface. With sufficient exposure, most orall of the metal catalyst can be removed from the

surface of the active element of the sensor.

Halogens and compounds containing halogen arematerials of this nature.

Examples:Chlorine

BromineIodine

Hydrogen Chloride, Bromide or IodideOrganic halides:

Trichloroethylene

DichlorobenzeneVinyl chloride

Freons

Halon 1301(Bromotrifluoromethane).

A brief exposure to one of these materials cantemporarily increase the sensitivity of the sensor.This results because the surface of the active

element is increased due to etching. Prolongedexposure continues the etching process until the

sensitivity of the sensor is degraded, resulting inshortened sensor life.

D. Exposure to high concentrations of combustiblegases.

Exposure of the sensor to high concentrations of

combustible gases for extended periods of timecan introduce stress to the sensing element and

seriously affect its performance. After exposure toa high concentration of combustible gas,recalibration should be performed and, if

necessary, the sensor should be replaced.

The degree of damage to the sensor is determinedby a combination of the type of contaminant, its

concentration in the atmosphere, and the length oftime the sensor is exposed. When a sensor hasbeen exposed to a contaminant or a high level of

combustible gas, it should be calibrated at the time,followed by an additional calibration a few days

later to determine whether a significant shift insensitivity has occurred.

E. A combination of accessories such as rain shieldsand dust covers is not recommended and can

result in slow response to a gas leak.

CALIBRATION GAS

Before calibrating a sensor, check the label on the

calibration gas cylinder to ensure that the correct gastype and concentration are being used. If a different

gas type is being used for calibration, refer to Det-Tronics Technical Note No. GTN01 for “K-Factor”information (Det-Tronics form number 99-1068-02).

Section VIGeneral Wiring Requirements

GENERAL INFORMATION

WARNING

Do not open any junction box or device enclosure when power is applied without first de-classifying

the hazardous area.

CAUTION Any deviation from the recommended wiring practices can compromise system operation.

Consult the factory if different wire types or methods are being considered.

NOTE

All wiring must be marked per NFPA 70 Article 760.

NOTE Specific installation requirements may differ

depending on local installation practices and compliance with third party certifications. For local

installation practices, consult the local authority having jurisdiction. For compliance with third party certifications, consult the appropriate appendix in

this manual for additional specific installation requirements.

POWER WIRING

The input voltage at the field devices must be 18 vdc

minimum to ensure proper operation of the devices.Therefore, it is important to consider both the size

(gauge) of the power wiring and the wiring distancefrom the power supply. As the wiring distanceincreases, larger diameter wire is required to maintain a

minimum of 18 vdc at the device.

Refer to Table VI-1 to determine the minimum wire sizeneeded to prevent excessive voltage drop from power

supply to device for a given current load.

To use Table VI-1, first determine the total current load

for the circuit and the maximum allowable voltage drop.Then look under the appropriate Amp Load column to

determine the minimum wire size that will not allow thevoltage drop to exceed the maximum allowable.

For example:

What wire size is required to power ten DCUs at adistance of 100 feet from the power supply, assuming a

24 VDC power supply and a minimum of 18 VDCneeded to power the DCUs?

Maximum allowable voltage drop is 6 VDC.(24 – 18 = 6)

Table VI-1—Voltage Drop Per Pair in Volts DC per 100 Feet from Power Supply to Device

NOTES: This table is for reference only and does not replace good engineering practice.Use Ohms Law when designing the power distribution system.

Voltage drop and wiring distance are proportional.Consult factory for assistance with system wiring requirements.



A combustible gas DCU draws approximately 500 mAat startup, therefore, the total current load is 5 amps.

(10 units x 500 mA = 5 amps)

Refer to the 5 Amp Load column in the table. Since the

maximum allowable voltage drop is 6 volts, 16 AWG (orlarger) wire is required.

IMPORTANT

To ensure proper operation of field devices, the voltage input to the device (measured at the device) must be within the range indicated for that

device in the “Specifications” section of this manual.

NETWORK WIRING

All devices on the LON/SLC are wired in a loop that

starts and ends at the LCU. To ensure properoperation, the LON/SLC should be wired using high

speed communication grade cable. Cable meeting the

specifications listed in Table VI-2 is suitable fordistances up to 2000 meters. Any of the cable typeslisted in Table VI-3 can be used for wiring the LON/SLC

for the distances indicated. If no network extenders areused, the distances listed are for the entire loop. Ifnetwork extenders are used, the distances listed are for

the wiring length between network extenders or

between a network extender and the LCU. The use ofother cable types can degrade system operation. For

optimum fault isolation performance, the maximumLON/SLC wiring length should not exceed 1600 feet

(500 meters).

SHIELD GROUNDING

Two shield ground terminals are provided inside the

junction box of each field device and also at the LCU.Connect the shield ends to the terminals provided (not

to each other) inside the junction box.

CAUTION

Insulate the shields to prevent shorting to the device housing or to any other conductor.

Be sure that selected cable meets all job specifications.

If necessary, consult factory for further suggested cable types.



JUNCTION BOX GROUNDING

Junction boxes should be electrically connected to

earth ground.

RS-485 LINK WIRING

The RS-485 link connecting the LCU and LIOU requires

termination at both ends. The LCU provides termination

for the beginning of the RS-485 link. All other devices,except for the device at the end of the line, shall havetheir termination resistor removed. The LIOU uses a

termination resistor that must be removed if it is not atthe end of the line.

All devices sharing a common RS-485 link must have acommon power return.

PROTECTION AGAINST MOISTURE DAMAGE

Moisture can have a detrimental effect on theperformance of electronic devices. Therefore, it is

important to take proper precautions during installationto ensure that moisture will not come in contact with the

electrical connections or components of the system.

In applications where the wiring cable is installed inconduit, the use of watertight conduit seals, drains,

breathers, or equivalent is recommended to preventdamage to electrical connections caused bycondensation within the conduit.

ELECTROSTATIC DISCHARGE

Many system electronic modules contain semiconductor

devices that are susceptible to damage by electrostaticdischarge. An electrostatic charge can build up on theskin and discharge when an object is touched.

Therefore, use caution when handling, taking care not totouch the terminals or electronic components. For more

information on proper handling, refer to Service Memoform 75-1005.

UV Flame Detector

WIRING REQUIREMENTS

Wiring to the UV detector must be between 12 and 18AWG with a minimum voltage rating of 600 volts rms

and a minimum temperature rating of 125°C. The use of

shielded cable is highly recommended to providemaximum protection from RFI/EMI interference.

1. Mount the Swivel Mounting Bracket using 1/4 inch

(M6) screws with a length of at least 1 inch (25 mm).The mounting surface should be free of vibration.

Allow adequate space around the swivel to facilitate

aiming and wiring of the detector. Armored flexible

conduit should be used for the final 3 feet (onemeter) of the cable run to allow for aiming andalignment of the detector.

2. Attach the detector to the Swivel Mounting Bracket.

3. Disassemble the detector enclosure by turning the

housing cover counterclockwise. See Figure VII-28.

NOTE

If the detector is equipped with a cover locking device, it must be loosened using a hexagonal (Allen) wrench.

4. Connect the wires to the appropriate screw terminalson the detector terminal block. See Figure VII-27 forterminal identification. Do not ground the shield to

the detector housing. (Tape off the shield and leaveit disconnected.)

5. Remove the UV sensor tube module from its

shipping package. When handling the sensor tubemodule, be careful not to touch the sensor tube,since oil from the skin can attenuate UV radiation,

reducing the sensitivity of the tube.

6. Using the index pin as a guide, install the sensormodule on the detector terminal block.

Determine the best mounting locations for the detectors.

Whenever practical, detectors should be placed wherethey are easily accessible for calibration.

WARNING

Do not apply power to the system with the cover removed unless the area has been verified to be

free of combustible gases or vapors.

The DCU utilizes the following:

1. A terminal wiring board mounted at the bottom ofthe junction box.

2. A communication module mounted above the

terminal wiring board using the standoffs provided.See Figure VII-33.

Assembly and Wiring Procedure

Attach the sensor to the DCU enclosure. Do not over-tighten. If a sensor separation kit is being used, attach

the sensor to the separation kit junction box and wirethe device as described in the “Sensor Separation”section.

CAUTION

The sensor threads can be coated with an appropriate grease to ease installation. Also lubricate the cover threads. (See “Ordering

Information” for part number).

Connect the external wiring to the appropriate terminalson the DCU terminal wiring board. Refer to Figure VII-

34 for terminal identification. See Figure VII-35 for anexample of a Det-Tronics electrochemical sensor

connected to a DCU.

Attach the communication module to the standoffs asshown in Figure VII-33. Connect the ribbon cable fromthe terminal wiring board to the communication module.

Set the address for the device. Refer to “Device

Address Switch Setting” in the “Switch Setting” sectionof this manual for complete information regarding the

switch setting procedure.

Check the wiring to ensure proper connections, then

pour the conduit seals and allow them to dry (if conduitis being used).

NOTE Before placing the cover back on the enclosure

following completion of assembly and wiring,inspect the enclosure O-ring to be sure that it is in good condition and properly installed. Lubricate

the O-ring and the threads of the cover with a thin coat of an appropriate grease to ease installation.

Refer to the “Ordering Information” section for the part number of the recommended grease

(available from Detector Electronics). If the installation uses catalytic type combustible gas sensors, it is imperative that lubricants containing

sil icone NOT be used, since they will cause irreversible damage to the sensor. Place the cover

on the enclosure. Tighten only until snug. Do not over tighten.

SENSOR SEPARATION FOR DCU WITH H2S AND O2SENSORS

Since the transmitter for the electrochemical sensor isalready mounted within the sensor housing, simply

mount the entire sensor assembly to the sensorseparation kit junction box and wire it to terminals 2 and

4 inside the DCU, the same as a regular (without sensorseparation) installation. Connect the shield to the

ground terminal in the DCU junction box.

Refer to Table VII-8 for separation distance limitations

for H2S and O2 sensors.

Sensor Separation with DCUEX

If the installation requires mounting the sensor in a

different location than the DCUEX, observe the followingguidelines.

When separating a combustible gas sensor from theDCUEX, two options exist:

1. Preferred MethodMount the transmitter PC board inside the sensorseparation junction box. This assembly can be

separated from the DCUEX by up to 1000 feet usingthree conductor 18 AWG shielded cable.

(Regardless of separation distance, operatingvoltage at the transmitter MUST be at least 18 vdc

to ensure proper operation.) See Figure VII-39.

Assemble the DCUEX without the transmitter board

similar to the DCU as shown in Figure VII-33. Plugthe sensor into P2 on the transmitter board. Use athree conductor 18 AWG shielded cable to connect

P1 on the transmitter board to terminals 2, 3 and 4on the DCU terminal board (see Figure VII-39).

Connect the shield to the ground terminal in theDCUEX junction box.

2. Alternate Method.

If the transmitter board must be mounted separatefrom the sensor (high temperature applications,

etc.), separate the sensor only, leaving thetransmitter PC board inside the DCUEX enclosure.When using this installation option, see Table VII-9

for maximum wiring distances.

Mount the sensor directly to the separation kitjunction box. Use three conductor shielded cablefor the connection between the terminal block in the

separation kit junction box and P1 on the transmitterboard. A plug with screw terminals is provided for

connecting the cable to P1 on the transmitter board.Observe the wiring color code. Connect the shield

to the ground terminal in the DCUEX junction box.SENSOR

GATEWAY

The gateway contains four 8-position DIP switchassemblies that are used for:

— Selecting serial port 1 software parameters

— Setting the gateway Modbus/Allen Bradley address— Selecting gateway relay operation (latching/non-

latching)— Setting the gateway type and address.

Refer to Figure VIII-1 to identify the function of the DIP

switches. Refer to Figure VIII-2 to locate the DIP switchassemblies on the side of the gateway.

S5 — Hardware Serial Port Configuration

Verify that S5 switches are set as follows:

1 — Open

2 — Closed

3 — Closed

4 — Open

5 and 6 — Closed

7 and 8 — Open.

S6 — Software Serial Port Configuration for Port 1

1, 2, and 3 — Determine the desired baud

rate, then refer to Table VIII-1for the proper switch settings.

(19,200 is recommended andcannot be exceeded in the

LCU.)

4 — Parity enable.Open = no parity.Closed = parity enabled.

5 — Parity type.

Open = odd.Closed = even.

6 — Stop bits.

Open = 1 stop bit.Closed = 2 stop bits.

LOGIC CONTROLLER

The logic controller contains three 8-position DIP switch

assemblies that are used for:

— Serial port configuration— Communication parameters

— Setting the LON/SLC address.

S5 — Hardware Serial Port Configuration

Verify that S5 switches are set as follows:

1 — Closed

2 — Open

3 — Open

4 — Closed

5 — Open

6 — Open

7 — Closed

8 — Open.

S6 — Diagnostic Serial Port Configuration

Diagnostic serial port is

intended for factory use only.Switch settings will not affect

normal operation.

S7 — LON/SLC Address

Set switches for the LON/SLC

address. Valid addresses arefrom 5 to 247, and must be an

odd number. If an addressoutside this range is selected,the address will default to 5.

S7-1 = LSB, S7-8 = MSB.

ISOLATION MODULE

A slide switch (SW1), located on the top edge of themodule, controls the 24 volt ground fault monitor

function.

On = EnabledOff = Disabled

Determine the type of LCU being used (Refer to thelabel on the LCU mounting cage.) Set SW1 as follows:

Off — EQ2100LCUOn — EQ2101LCU

LON/SLC DEVICE ADDRESS SWITCHSETTING

Each individual device on the LON/SLC must beassigned a unique address. Addresses 1 to 4 are

reserved for gateway use. Address 1 is for the maingateway. Valid addresses for field devices are from 5 to

250. If the address is set to zero or an address above250, the communication module will ignore the switch

setting. Duplicated addresses are not automaticallydetected. All modules with the same address will reporton that address. The status word will show the latest

update, which could be from any of the reportingmodules at that address.

NOTE Logic controllers utilize two consecutive LON/SLC

addresses, the first of which must be an odd number, i. e. a Logic Controller with an address of

7 will occupy both 7 and 8 on the LON/SLC.

Selection of the node address for field devices is

accomplished by setting rocker switches on a DIPswitch assembly. (Note that only the first eight of the 12switches are used for selecting the address.) Theaddress number is binary encoded with rocker switch

No. 1 on the 8 position switch assembly being the LSB(least significant bit). Each rocker switch has a specific

binary value, as shown in Figure VIII-3. The nodeaddress is equal to the added value of all closed rocker

switches. All open switches are ignored. For example:for node No. 5, close rocker switches 1 and 3 (binaryvalues 1 + 4); for node No. 25, close rocker switches 1,

4 and 5 (binary values 1 + 8 + 16).

Power must be cycled before the new address will takeeffect.

For your convenience in setting the address switches,refer to the table “Address Switch Settings” at the back

STARTUP PROCEDURE

1. Output loads that are controlled by the systemshould be secured (remove power from all outputdevices) to prevent actuation.

2. Check all system wiring for proper connection.

3. Before installing devices in the mounting racks,

inspect them to verify that they have not beenphysically damaged in shipment. Check the rockerswitches for proper programming, then slide the

device fully into the mounting rack.

4. Apply power to the system.

NOTE

To prevent the network modules from going into a fault isolation condition, apply power to the LCU

prior to applying power to the network devices.

5. Program the system for the desired operation usingDet-Tronics configuration software. Refer to

software manual, form number 95-8479-02.Download configuration data to all devices.

NOTE After system configuration has been completed,the entire system should be tested for proper

operation to ensure that configuration was performed properly.

6. Calibrate the sensors.

7. Ensure that all trouble and alarm conditions have

been cleared and the LCU reset, then removemechanical blocking devices (if used) and restore

power to the output loads.

CALIBRATION

To ensure optimum performance, calibration must be

performed on a regularly scheduled basis. Since eachapplication is different, the length of time between

regularly scheduled recalibrations can vary from oneinstallation to the next. In general, the more frequently a

system is checked, the greater the reliability.

IMPORTANT 4 to 20 ma devices not manufactured by Det- Tronics must be pre-cal ibrated. To ensure

adequate protection, calibration must be performed on a regularly scheduled basis.

NOTE The calibration will be aborted and the detector will

revert back to the previous calibration values if the calibration is not completed within 12 minutes. The

red LED will blink. The calibration will be logged as aborted.

NOTE The “Sensor Replacement” calibration procedure

must be used for the initial calibration of a new sensor. The “Routine Calibration” procedure can

then be used for all subsequent calibrations.

NOTE

Some calibration procedures require the operator to activate the reed switch located on a circuit

board inside the junction box. See Figure IX-1 for the location of the reed switch. To activate the

reed switch, hold the calibration magnet against the side of the junction box near the switch location

approximately one inch above the mounting surface. (Do not open the junction box.) Hold the calibration magnet in place for about 4 seconds to

initiate steps of the calibration procedure.

UV DETECTOR TEST

CAUTION

To prevent unwanted actuation, alarm and extinguishing devices must be disconnected prior

to performing detection system tests.

FIRE ALARM TEST

1. Disable any ext inguishing equipment that isconnected to the system.

2. Apply input power to the system. Allow a one

second power-up delay.

3. Hold a UV source (W8066) within the cone of visionof the detector at a distance relative to the selected

detection range. Verify that an alarm condition isindicated at the LCU. Reset the alarm indicationusing the key switch on the LCU.

Lack of response may indicate reduced sensitivitydue to contamination on the viewing window, a

damaged sensor, or electronic circuitry or wiringproblems. Refer to “Troubleshooting” for additional

information.

4. Repeat this test for each fire detector in the system.

5. Verify that all detectors are properly aimed at the

area to be protected.

6. Enable extinguishing equipment when the test iscomplete.

FALSE ALARM TEST

1. Disable all alarm response equipment.

2. Allow the system to monitor the protected area for a

period of time with all the normal operations in thearea taking place. If the detector responds(indicating a fire when no fire has occurred), check

the area to see if UV sources are present. If

possible, remove the sources, or reposition thedetectors so that the sources fall outside of thedetector’s cone of vision. If problems still occur,

adjust the time delay, sensitivity or arc rejectionsettings.

The model U7656 Hand-Held UV Monitor isavailable from Detector Electronics for conveniently

scanning the protected area and pin-pointing theexact source of UV radiation.

3. Recycle power and test again as described above.

4. Once the correct settings are obtained, turn on allalarm and extinguishing equipment that is

connected to the system. Record all switch settingsfor future reference.

UV/IR DETECTOR TEST

IMPORTANT Disable any extinguishing equipment that is

connected to the system to prevent unwanted actuation.

The detector can be tested by shining a UV/IR test lamp(W867 or W8067) into the detector viewing windows orby a live fire. (Refer to the test lamp manual for specific

instructions regarding proper use of the device.) Thiswill cause the detector to go into an alarm condition —the LEDs on the UV sensor will be on steady and the

LCU will indicate an alarm condition. If latchingoperation is selected, the detector will remain in this

condition until it is reset at the OIS. If non-latchingoperation is selected, the detector will return to normal

operation as soon as the test is terminated (the testlamp or fire source is removed).

If a fire signal was not generated and the LEDs indicateresponse by only one sensor, the other sensor has

failed to respond.— Check the cleanliness of the viewing window and

repeat the test.— If the sensor fails to respond again, replace the

sensor module.

— If the sensor still does not respond, replace thedetector.

IX-7 95-8470



If a fire signal was not generated and the LEDs indicateresponse by neither sensor, both sensors have failed to

respond.— Check input power and external wiring.— Check the cleanliness of both viewing windows.

— If the detector still does not respond:— If using a test lamp, check the battery, window, etc.

to be sure that the test lamp is working properly.— If the detector still does not respond, replace the

detector.

MANUAL oi

When manual oi is selected, the automatically initiated

oi test is disabled.

Regardless of the oi selection, internal diagnosticcircuitry will respond to failures such as a loss of inputpower or to certain electronic failures. These failures

will be indicated at the LCU and also by the detector’sLEDs. If such a failure occurs, check the operation of

the power source and the continuity of the detector

wiring. If the detector appears to be “dead” with powerapplied, it must be returned to the factory for repair.

AUTOMATIC oi

The Automatic oi feature (if selected) tests the detector

at the selected interval (once per minute for UV andfrom once a minute to once every four hours for IR),

checking the cleanliness of the optical surfaces, sensorsensitivity, and proper functioning of the electronic

circuitry. If a problem is detected for three consecutiveautomatic oi tests, a fault signal is generated at theLCU (also indicated by the UV sensor LEDs). If the

detector passes three subsequent automatic oi tests,the fault signal will be cleared

UV Fault

To correct a UV oi fault, clean the viewing window and

oi ring of the UV sensor, and also check the oi ring

opening for proper orientation. If the fault does notclear (or fault reoccurs), a faulty sensor or electrical

problem is indicated. First replace the UV sensormodule. If the problem persists, replace the detector.

IR Fault

To correct an IR oi fault, clean the viewing window and

oi ring of the IR sensor, and also check the module and

oi ring opening for proper orientation. If the fault does

not clear (fault reoccurs), a faulty sensor or electricalproblem is indicated. Check the connection of theconnector plug on the IR module. Also check the

condition of the wires. Repair or replace if needed. If

the problem persists, replace the IR sensor module. Ifthe problem still persists, replace the detector.

General Fault

If a general fault is indicated, check input power to the

detector as well as continuity of system wiring. Alsocheck the detector viewing windows for contamination

such as paint overspray, snow, etc. that couldsimultaneously affect both sensors. Since simultaneous

failure of both sensor modules is unlikely, the problem ismost likely caused by loss of input power or failure ofthe detector’s electronic circuitry.

Background Radiation

Background radiation as such does not cause a

problem with the detector in most applications, unlessboth UV and flickering IR non-fire radiation sourcesoccur simultaneously. If a UV or IR background

radiation indication occurs:— Determine its cause. The presence of background

radiation could indicate a problem in the protectedarea. For example, background IR could be

caused by overheating equipment.— Determine whether or not repositioning the detector

could eliminate response to the backgroundradiation without reducing coverage of thehazardous area.

Section XISystem Maintenance

ROUTINE MAINTENANCE

To ensure reliable protection, it is important to checkand calibrate the system on a regularly scheduledbasis. The frequency of these checks is determined by

the requirements of the particular installation.

MANUAL CHECK OF OUTPUT DEVICES

It is important that response devices be checked initiallywhen the system is installed, as well as periodicallyduring the on-going maintenance program.

CAUTION

Be sure to secure all output devices that are actuated by the system to prevent unwanted activation of this equipment, and remember to

place these same output devices back into service when the checkout is complete.

O-RING MAINTENANCE



A rubber O-ring is used to ensure that the junction boxcover will seal tightly and provide protection against

water ingress. Periodically the enclosure should beopened and the O-ring should be inspected for breaks,

cracks and dryness. To test the ring, remove it from the

enclosure and stretch it slightly. If cracks are visible, itshould be replaced. If it feels dry, a thin coating oflubricant should be applied. When re-installing the ring,be sure that it is properly seated in the groove on the

housing. It is imperative that this O-ring be properlyinstalled and in good condition. Failure to properly

maintain it can allow water to enter the enclosure andcause premature failure. A coating of lubricant should

also be applied to the threads on the cover before re-assembling the enclosure. This will both lubricate thethreads and help to prevent moisture from entering the

enclosure.

CAUTION The O-rings should be lubricated with a silicone free grease. The use of other lubricants is not

recommended, since they can adversely affect the performance of some sensors. Under no

circumstances should a lubricant or compound containing silicone be used on systems using catalytic type combustible gas sensors.

FLAME DETECTOR MAINTENANCE

The flame detector requires no periodic calibration.

However, to maintain maximum sensitivity, the viewingwindow must be kept clean at all times.

To clean the optical surfaces, remove the oi ring fromthe detector by gently squeezing the tabs together and

then pulling out. Clean the viewing window and the

back side of theoi ring using a clean cloth or tissueand Det-Tronics window cleaning solution. Avoid the

use of commercial glass cleaners, since many of them

can leave a UV absorbing residue on the surface.Avoid leaving fingerprints on the reflective surface of the

oi ring. Re-install the ring so that the opening is

positioned downward.

NOTE

If corrosive contaminants in the atmosphere cause the reflective rings to deteriorate to the extent that

it is no longer possible to restore them to their original condition, they must be replaced.

To ensure the watertight integrity of the detector, the O-

rings must be maintained following the guidelinesdescribed above.

GAS SENSOR MAINTENANCE

All gas sensors must be calibrated on a regularlyscheduled basis, typically every 90 days for catalytic

and electrochemical sensors and annually forPointWatch.

Catalytic sensors have a finite lifespan. If a successful

calibration cannot be performed, replace the sensorand recalibrate following the procedure described in the“Calibration” section. Exposure of the sensor to high

concentrations of combustible gases for extendedperiods of time can introduce stress to the sensing

element and seriously affect its performance. Afterexposure to a high concentration of combustible gas,

recalibration should be performed and, if necessary, thesensor should be replaced.

Electrochemical sensors have a finite lifespan. If asuccessful calibration cannot be performed, inspect the

hydrophobic filter. If the filter is plugged, replace it andrecalibrate the sensor. If the filter is in good condition,

replace the sensor. Recalibrate following the proceduredescribed in the “Calibration” section.

If the PointWatch fails calibration, refer to thePointWatch manual.

NOTE Compare part numbers to be sure that the correct

replacement sensor is being used.



XI-2

BATTERIES

Batteries must be replaced every 48 months, or soonerif required by local codes. Only sealed batteries are to

be used.

TROUBLESHOOTING

Table XI-1 is intended to serve as an aid in locating the

cause of a system malfunction. If the problem cannot

be corrected, contact the factory for assistance.

REPLACEMENT PARTS

Eagle devices are not designed to be repaired in the

field. If a problem should develop, first carefully check

for proper wiring, programming and calibration. If it isdetermined that the problem is caused by an electronic

defect, the device must be returned to the factory forrepair.

NOTE When replacing a device, be sure that the rocker switches on the replacement are set the same as

the original. Remove power before removing or

plugging in the replacement unit. When a DCU,IDC or flame detector is replaced, the point must be re-configured. If the auto-configure feature is

enabled, configuration is done automatically.
