1.1.2 System Description

General: Non-coded, addressable-analog system with manual and automaticalarm initiation; automatic sensitivity control of certain smoke detectors; and mul-tiplexed signal transmission dedicated to fire alarm service only.

Scope of Work: Provide the following:

FACP manual stations, automatic fire detectors, interface with other systems, wiring, wire-ways and all accessories to form a complete system.

1.1.3 Quality Assurance

Codes and Standards: Comply with the following:

NFPA 70, "National Electrical Code". NFPA 72, "National Fire Alarm Code". NFPA 101, "Code for Safety to Life from Fire in Buildings and Structures".

1.1.4 Functional Description System

Control of System: Fire Alarm Control Panel (FACP).

System Supervision: Automatically detect and report open circuit, short circuit,and ground fault of wiring for initiating device, signaling line, and notification-ap-pliance circuits. System shall detect ground fault by panel, loop circuit, and de-vice.

Priority of Signals: Automatic alarm response functions resulting from an alarmsignal from 1 zone or device are not altered by subsequent alarm, supervisory, or trouble signals. An alarm signal has the highest priority. Supervisory and troublesignals have second- and third-level priority. Higher-priority signals take prece-dence over signals of lower priority, even when the lower-priority condition occursfirst. Annunciate and display all alarm, supervisory, and trouble signals regard-less of priority or order received.

Noninterference: A signal on one zone shall not prevent the receipt of signalsfrom other zones.

System Reset: All zones are manually re-settable from the FACP after initiating

devices are restored to normal.


2/31

System shall continually monitor any changes in the sensitivity of individualsmoke or heat sensors due to environmental effects.

The Contractor shall provide all necessary hardware, software, and auxiliaries toensure the following functions are fulfilled:

Connection to airport network for interfacing with all other fire alarm systemsinstalled in the other buildings in the airport site.

One main Graphic User Interface (GUI) located in the Security Room shallcontrol and monitor all fire alarm system and points of the new system speci-fied herein and the other fire alarm systems installed in the different buildingswithin the airport. It shall have full control and monitoring of these new firealarm systems through 2-way communication.

The entire fire alarm system including integration arrangement detailed in (1)above shall be UL listed for life safety applications.

System Alarm Capability during Circuit Fault Conditions: System wiring and cir-

cuit arrangement prevent alarm capability reduction when an open circuit, groundor wire-to-wire short occurs, or an open circuit and a ground occur at the sametime in an initiating device circuit, signal line circuit, or notification-appliance cir-cuit.

Initiating Device Circuits (IDC) System Wiring: Class A, Style D or E. Signaling Line Circuits (SLC) System Wiring: Class A, Style 7. Notification Appliance Circuits (NAC): Class A, Style Z.

Loss of primary power at the FACP initiates a trouble signal. The FACP indicateswhen the fire alarm system is operating on the secondary power supply.

Basic Alarm Performance Requirements: Unless otherwise indicated, automaticalarm operation of a smoke or heat detector initiates the following:

Activation of presignal at FACP

a. Local alarm in the control panel for the period of a programmable time T1. b. During this delay time (T1), a local (staff) alarm (stage 1) only is to be giv-

en. If the alarm is not acknowledged before timer T1 runs out, this is toresult in notification-appliance operation (stage 2) as detailed in subpara-graph 1.1.4 below.

c. If the alarm is acknowledged while T1 is still running, T1 is to be reset anda programmable timer T2 is to be started. T2 is to delay the notification-

appliance operation (stage 2) further, and so provide time for human in-vestigation of the alarm cause.

d. If no reset action takes place before T2 runs out, notification-applianceoperation (stage 2) is to be given.

Notification-appliance operation (stage 2).a. Evacuation signal throughout the building.b. Activation of visual strobes.

Identification at the FACP of the location and the type of device originatingthe alarm.

Shutdown of fans and other air-handling equipment serving zone when alarmwas initiated.


3/31

Closing of smoke dampers in air ducts of system serving zone where alarmwas initiated.

Recording of the event in the system memory. Initiate operation of smoke management system. Recording of the event by the system printer.

All operations shall be according to the approved cause & effect matrix.

Alarm Silencing, System Reset and Indication: Controlled by switches in theFACP

Silencing switch operation halts alarm operation of notification appliances andactivates an "alarm silence" light. Display of identity of the alarm zone or de-vice is retained.

Subsequent alarm signals, from other devices or zones, shall reactivate notifi-cation appliances, until silencing switch is operated again.

When alarm initiating, do not return to normal status, and system reset switch

is operated; notification appliances operate again until alarm silence switch isreset.

When fire alarm system is reset, all auxiliary systems shall be released fromfire mode.

Remote Detector Sensitivity Adjustment: Manipulation of controls at the FACPcauses the selection of specific addressable smoke detectors for adjustment, dis-play of their current status and sensitivity settings, and control of changes inthose settings. Same controls can be used to program repetitive, scheduled, au-tomated changes in sensitivity of specific detectors. Sensitivity adjustments andsensitivity-adjustment schedule changes are recorded in system memory and areprinted out by the system printer.

Removal of an alarm-initiating device or a notification appliance initiates the fol-lowing:

A "trouble" signal indication at the FACP for the device or zone involved. Recording of the event by the system printer. Recording of the event in the system memory.

Printout of Events: On receipt of the signal, print alarm, supervisory, and troubleevents. Identify zone, device, and function. Include type of signal (alarm, super-visory, or trouble), and date and time of occurrence. Differentiate alarm signalsfrom all other printed indications. Also print system-reset event, including thesame information for device, location, date, and time. Commands initiate theprintout of a list of existing alarm, supervisory, and trouble conditions in the sys-tem and a historical log of events.

FACP Alphanumeric Display: Plain-English-language descriptions of alarm, su-pervisory, and trouble events; and addresses and locations of alarm-initiating or supervisory devices originating the report.

1.1.11 Wiring Installation

Wiring Method: Install wiring in raceway according to Division 16 Section "Race-ways and Boxes." Conceal raceway except in unfinished spaces and as indicat-ed.

Wiring within Enclosures: Separate power-limited and non-power-limited conduc-tors as recommended by the manufacturer. Install conductors parallel with or atright angles to sides and back of the enclosure. Bundle, lace, and train conduc-tors to terminal points with no excess. Connect conductors that are terminated,spliced, or interrupted in any enclosure associated with the fire alarm system toterminal blocks. Mark each terminal according to the system's wiring diagrams.Make all connections with approved crimp-on terminal spade lugs, pressure-typeterminal blocks, or plug connectors.

Cable Taps: Use numbered terminal strips in junction, pull and outlet boxes, cab-inets, or equipment enclosures where circuit connections are made.

Color-Coding: Color-code fire alarm conductors differently from the normal build-ing power wiring. Use one color-code for alarm circuit wiring and a different col-or-code for supervisory circuits. Color-code audible alarm-indicating circuits dif-ferently from alarm-initiating circuits. Use different colors for visible alarm-indicat-ing devices. Paint fire alarm system junction boxes and covers red.

Risers: Install at least 2 vertical cable risers to serve the fire alarm system. Sep-arate risers in close proximity to each other with a minimum 1-hour-rated wall, sothat the loss of one riser does not prevent the receipt or transmission of signalfrom other floors or zones.

1.1.12 Field Quality Control Verify the absence of unwanted voltages between circuit conductors and ground.

Test all conductors for short circuits using an insulation-testing device.

With each circuit pair, short circuit at the far end of the circuit and measure thecircuit resistance with an ohmmeter. Record the circuit resistance of each circuiton Record (As-Built) Drawings.

Verify that the control unit is in the normal condition as detailed in the manufac-turer's operation and maintenance manual.

Test initiating and indicating circuits for proper signal transmission under opencircuit conditions. One connection each should be opened at not less than 10


8/31

percent of initiating and indicating devices. Observe proper signal transmissionaccording to class of wiring used.

Test each initiating and indicating device for alarm operation and proper re-sponse at the control unit. Test smoke detectors with actual products of combus-tion.

Test the system for all specified functions according to the approved operationand maintenance manual. Systematically initiate specified functional perfor-mance items at each station, including making all possible alarm and monitoringinitiations and using all communications options. For each item, observe relatedperformance at all devices required to be affected by the item under all systemsequences. Observe indicating lights, displays, signal tones, and annunciator in-dications. Observe all voice audio for routing, clarity, and quality, freedom fromnoise and distortion, and proper volume level.

1.1.13 Fire AppliancesConsistent with the life safety laws provisioning for manually operated fireextinguishers has been made in accordance with the type of risks identified andevaluated for the designated areas. Rooms of spaces that are identified to haveClass A fire threat perception are provided with water extinguishers. Similarly for Electrical Fires belonging to Class B we have provisioned the Carbon DioxideExtinguishers and Foam appliances for the Class A & B types of fire.

All the fire extinguishers are well mounted and are located at or adjacent to the exitareas in line with the life safety code.

Water ExtinguishersPortable hand operated water fire extinguishers are usually available in 9 litrecapacity with a fire extinguishing rating of 2 A. The extinguisher weighsapproximately 14kg and has a solid stream range of approximately 10.7 - 12.2metres horizontally. This extinguisher can be used intermittently but under continuous use it has a discharge of 50-55 seconds.

Foam ExtinguishersThese extinguishers are commonly manufactured in 9 litre rating and are intendedfor use on Class A and Class B fire(s). On flammable liquid fires of appreciabledepth, best results are obtained when the discharge from the extinguisher is playedagainst the inside of the back wall of the vat or tank just above the burning surfaceto permit the natural spread of the foam back over the burning liquid. Theextinguishing agent is a solution of aqueous film forming (AFFF) surfactant in water that forms mechanical foam when discharged through the aspirating nozzle. On

Class A fires the agent acts as both coolant and penetration to reducetemperatures below the ignition level. On Class B fires it acts as a barrier toexclude air or oxygen from the fuel surface.

Carbon Dioxide ExtinguishersPortable Carbon Dioxide extinguishers are designated with a discharge horn.These extinguishers require a two hand operation. The Carbon Dioxide is retainedunder its own pressure in fluid form at room temperature. The agent is self expelling and is discharged by an operation of the cylinder valve that causes theCarbon Dioxide to be expelled through a horn in its vapour and solid phase.Carbon Dioxide Extinguishers are specifically effective on Electrical Fire conditions.
