Fire Suppression Release Panel Technical Information

Addressable Release Control Panel: A Release Control Panel (RCP) that utilizes addressable devices that are assigned an address (name) which is identified by the RCP. When an alarm or trouble condition occurs, the assigned address and associated custom message is displayed. Devices connected to an addressable RCP must be approved for use with that panel. A non-addressable device will not work on an addressable RCP unless connected to a compatible addressable contact monitor module.

Conventional Release Control Panel: A Release Control Panel (RCP) that does not display the name of the device that has been activated or “trouble” condition but only displays the zone that the device is connected to. Lights (LED’s) on the RCP are illuminated for zones in alarm or trouble.

Non-volatile History Buffer: Memory of previous activities will not be lost upon loss of all electrical power sources i.e., AC or battery. All U. L. Listed addressable RCP acceptable to Chrysler LLC have a non-volatile history buffer that records all events including alarm and trouble conditions.

Approved Chrysler LLC panels listed under section 4.3.1 are addressable RCP’s with a non-volatile history buffer. Conventional RCP’s are not acceptable.

There are dry relay contacts within the RCP that are connected to various interlocks. Before a gaseous agent is discharged equipment/processes are shut-down/e-stopped. Exhaust and supply air must be shutdown. Where applicable, dampers within ductwork will be interlocked to close.

A smoke detector is not required over the release control panel as Chrysler has determined that this panel is not part of the building fire alarm system. However, if the AHJ requires this detector, then it shall be wired (separate address) to the building fire alarm system, and not the release control panel.

SINGLE HAZARD PANELS (SHP)

SHP’s are normally not acceptable for any Chrysler LLC installation. Written permission must be obtained in advance from the Chrysler LLC Corporate Fire Prevention Engineer. A contractor shall not automatically bid using a SHP unless the Chrysler LLC specifications specifically state that a SHP can be used.

Fire Release Panels

The following is a basic description of Release Control Panels (RCP) acceptable for use at Chrysler LLC facilities for the release of a fire suppression agent such as HFC-227ea (FM-200), HFC-125 (ECARO), carbon dioxide, dry chemical, high-speed deluge, etc. These panels can be used as a building fire alarm control panel (FACP). At a given facility, several RCPs may be connected to one FACP.

It takes several devices/components to makeup a fixed fire suppression system. Systems include devices as manual pulls, smoke detectors, heat detectors, flame detector, strobes, horns, speakers, modules, relays, cable, conduit, extinguishing agent, cylinders, tanks, batteries, etc.

Release Control Panel’s are to be located within a lockable NEMA-12 enclosure that also contains various relays, modules, switches, batteries, power supply, battery charger, wiring, etc. This panel must be located outside the protected space or room. Panel shall accept Chrysler LLC Padlock.

Release Control Panels contains relays and terminal blocks used to attach wires connected to the power supply, Notification Alarm Circuits (NAC), Initiating Device Circuits (IDC), and Signaling Line Circuit(s), etc. The RCP contains and executes all control-by-event programs for specific action due to detection of a fire. It stores all the system’s operational parameters (programmed) in non-volatile memory (different from the history memory (buffer)). The RCP contains the real clock for the date and time used for the history memory to display and print “alarm” and “trouble” events.

The following are two sections from Chrysler LLC - Corporate Fire Protection Standard #101.

The releasing control panel shall be UL listed and Factory Mutual approved, per panels listed in Section 4.4 or Chrysler approved equal. The control panel shall provide power for all fire sensors with twenty-four (24) hour battery backup. The control panel shall have the following features:

- The control panel shall be capable of linking up to a minimum of one hundred twenty-seven (127) addressable devices per circuits.

- The control panel shall provide a separate custom thirty-two (32) character message for each addressable device.

- The control panel shall provide a non-volatile memory that retains all alarms or trouble conditions in the event both primary and secondary power is lost. Memory shall be accessible through use of an IBM Compatible Personal Computer.

The control panel shall be field programmable using a laptop computer without reprogramming of computer proms or by other means.

The release control panels must not be located within the protected hazard (room or space)

Electrical conduits shall enter from side of enclosure or cabinet unless prior approval from Chrysler LLC Corporate Fire Prevention Engineer.

6.1 Wiring Requirements

Wiring requirements for the complete system shall be per manufacturer specifications. By-pass switches must be located inside control cabinets and shall be accessible only to the local Wackenhut Security Dept.

All electrical conduit/penetrations shall enter fire release control enclosures from the side of enclosure only.

All penetrations and terminations made to the fire release control enclosure shall be made or supervised by the supplier of the fire release panel and enclosure.

Solid wires shall not be permitted regardless of gauge size.

Control modules, Releasing modules, Relay modules, Monitoring modules, batteries, purge fan switches, etc. must be located within lockable Control Panel enclosure unless approved by Corporate Fire Prevention Engineer. Modules shall not be located within equipment cabinets or enclosures.

9.0 Intermediate Bulk Containers

Intermediate Bulk Containers (IBC’s)

Intermediate Bulk Containers (IBC’s) are defined by DOT and NFPA No. 30 as rigid or composite plastic containers containing >119-gallons up to 793-gallons. Most common unit size is 275-gallons. NFPA 30 has fire protection requirements for UL 2368 listed IBC’s

Composite plastic intermediate bulk containers that contain liquids are “metal cage” or “bag-in-the-box” types. “Composite” refers to multiple materials of construction, typically polyethylene (inner container) and steel (outer system).

In some codes, IBC’s are also known as “Rigid non-metallic IBC’s”.

Most Fire Codes limit use of composite IBC’s to store Class II and III liquids only. Current fire codes do not allow Class I flammable liquids in composite IBC’s

IBC’s by themselves do not typically “start” a fire but large leaks of flammable and/or combustible liquids serve as a significant fuel sources. An unprotected IBC could fail rapidly during a fire exposure and rush 275-gallons (or more) of fuel into an existing fire.

Besides adequate ceiling automatic sprinkler protection, adequate containment must be provided for any anticipated spill.

15.0 Carbon Dioxide Systems

Carbon Dioxide Fire Protection System Minimum Requirements

Scope:

This section contains minimum requirements for carbon dioxide fire protection systems. It includes only the basic essentials to make the standard workable in the hands of those trained & skilled in this field. Only those with the proper training and experience shall design, install, inspect, and maintain this equipment. Examples of proper training would be factory certification by a particular system manufacturer.

The entire system shall comply with the most current edition of NFPA #12 and this document.

Systems:

Two major type carbon dioxide systems used at Chrysler LLC facilities – Total Flooding systems and Local Application systems.

Total Flooding System – consists of a fixed supply of carbon dioxide normally connected to fixed piping with nozzles arranged to discharge carbon dioxide into an enclosed space or enclosed space around the hazard.

Local Application System - consists of a fixed supply of carbon dioxide normally connected to fixed piping with nozzles arranged to discharge carbon dioxide directly on the burning materials.

Agent Storage Containers:

Carbon dioxide extinguishing systems use either high-pressure storage units (cylinders at room temperature usually in 75 or 100 lb. capacity for industrial applications) or low pressure storage units (large refrigerated tanks – ¾ ton or larger). Ansul’s Mini-bulk low-pressure system range from 500-lb. to 1,500-lb. Capacity and are considered low- pressure systems.

System storage container selection is primarily based upon economics that is strongly influenced by hardware requirements. Typically, selecting a low-pressure storage container becomes more favorable as system carbon dioxide requirement increase. Multiple timed discharges are also possible with low-pressure storage containers.

High Pressure – Indicates that the carbon dioxide is stored in pressure containers at atmospheric temperatures. At 70 F, the pressure in this type storage is 850 psi.

Low Pressure - Indicates that the carbon dioxide is stored in pressure containers at controlled temperatures, at 0 F. At 0 F, the pressure in this type storage is 300 psi.

Extinguishing Mechanism:

Carbon dioxide extinguishes a fire by oxygen depletion and reducing the oxygen content from the normal 21% in air to 15%. This will extinguish most fires. The cooling effect created by a carbon dioxide discharge is of little significance. Since it is a gas, it will penetrate and spread to all parts of a hazard. Carbon dioxide does have a density about 50% greater than the density of air.

Applications:

Based upon property insurance requirements and Chrysler LLC Corporate Standards, carbon dioxide shall not be a replacement for providing automatic sprinkler protection, unless approved by the Chrysler LLC Corporate Fire Prevention engineer. A carbon dioxide fire suppression system can be used to provide supplemental fire protection in the following areas:

Standard 10736

Within machine enclosures, associated ductwork and oil mist collector(s) using combustible cutting oil.

NOTE: Carbon dioxide protection can be omitted within horizontal ductwork and oil mist collector if all three of the following conditions are met and approved by local AHJ:1). There is a damper on all vertical ductwork interlocked to close automatically prior to discharge of the carbon dioxide system.2). All horizontal ductwork and oil mist collector(s) have automatic sprinkler protection. Also, the ductwork must be designed to hold the additional weight of the sprinkler water discharge.3). Carbon dioxide system is designed to protect the entire machine enclosure and vertical ductwork. Within unmanned pits such as caster/camber, roll test, BSR pits, etc. (if manned pits, HFC-227ea

(FM-200) shall be used) Within normally unmanned rooms, if approved by the Corporate Fire Prevention engineer. An

Standard 10740

16.0 Fire Alarm Systems

16.1 System Types

Fire protection signaling systems are classified according to the function they are expected to perform. Types of systems are as follows:

16.1.1 Local System

The purpose of a local protective signaling system is to sound local alarm signals for evacuation of the protected building.

The basic features of a local protective signaling system are:- A control panel.- A primary (main) power supply that usually is the local power service.- A secondary (stand-by) power supply (batteries).- Initiating devices such as detectors, manual fire alarm boxes, water-flow alarm devices, and

other alarm initiating devices.- Signaling devices such as bells, horns, speakers or central station annunciation.

A local alarm system may not relay a signal automatically to a central station or fire department. Therefore, when a local alarm “sounds” and the system is not connected to a central station or fire department (typically in office buildings) personnel must notify the fire department.

16.1.2 Auxiliary Systems

An auxiliary protective signaling system has circuitry connecting alarm initiating devices to the municipal fire alarm system (fire department) either through a master fire alarm box or through a dedicated telephone line connected directly to the municipal communication central switchboard. The signal received by the fire department is the same received when someone manually activates any municipal fire alarm box.

16.1.3 Remote (Central) Station Systems

A remote station signaling system has an alarm signal that is received at a remote location that is attended by trained personnel 24 hours a day (constantly attended). The receiving equipment is located at a facility other than the fire department, such as a police station or telephone answering service. The signal is transmitted over a leased telephone line, and is indicated audibly and visually at the remote station. Remote station personnel notify the fire department of the alarm.

16.1.4 Proprietary Systems

The proprietary system is a widely used type of control unit in large commercial and industrial occupancies.

Proprietary and central station systems are similar in operation. The main difference is as follows:

The station (location) receiving the fire alarm signal in a proprietary system is operated by personnel with a proprietary interest in the protected buildings (on-site).

Central station system is staffed by operators who perform the service for a fee and have no proprietary interest in the protected buildings.

The proprietary system receiving station is a security office within or near the building (or group of buildings) protected by the system.

Standard 10741

Many existing proprietary systems have separate initiating device circuits for each building zone or subsection, similar to the local, auxiliary, and remote station systems. With the increasing use of electronics, proprietary systems for larger buildings have signals multiplexing and built-in computer systems. These systems receive all signals from the building over one or more pairs of wires and determine the exact location of a fire by use of different frequencies or digitally coded information transmitted over the multiplex system.

16.2 Points to Alarm

Points to alarm include the following:

- Water flow switches (vane type and pressure switch)The alarm contractor shall make the initial setting on the water flow alarms. The maximum time for the water flow to received alarm at the proprietary or central station shall be no longer than 90 seconds.

- All water flow alarms must be able to be tested. This is accomplished by piping the alarm line to a fixed drain or into the water wash in a paint shop. If the above is not accessible then a 5/8” quick disconnect to accept a 5/8 inch garden type hose shall be provided.

- Valves (exterior valves, SCV, PIV, Wall valves do not require tamper switches. A means to lock the valves shall be supplied. Lock NPN code 35-610-0864

- Detectors (smoke, heat, flame)- Manual pull stations- Special Suppression Systems

- Discharge of Agent- System trouble

Fire alarm systems provide several distinct types of audible signals as follows:

- Trouble Signal - A “trouble signal” is given when a fault occurs in a supervised (monitored) device or circuit of a protective signaling system. Circuits that are normally supervised included main power, alarm initiating and alarm signaling circuits. Trouble signals for remote station auxiliary systems are received at a central supervisory station. In local and proprietary systems, trouble signals are “sounded” in areas where personnel are normally present.

- Supervisory Signal - In sprinkled occupancies, a sprinkler “supervisory signal” is given when a critical component in the sprinkler system is in an abnormal condition. These conditions include such factors as low water service pressure, loss of power to a fire pump, closing of a water supply valve, low water level of a water supply tank, or near freezing temperature in an outdoor water supply tank. Local and proprietary system supervisory signals are usually “sounded” in areas where personnel are normally present. Remote station and auxiliary system supervisory signals are received at the receiving station.

- Alarm Signal - When a fire is detected, an alarm signal is transmitted upon operation of either a manual or automatic initiating device (manual pull station, suppression system, or detector).

Although alarm signals generally involve the sounding of audible signals throughout a building, signals may be “sounded” only in the vicinity of the immediate fire area of large buildings. The alarm signal may be a taped or live voice message broadcast over a fire alarm speaker system.

These signals are either coded or un-coded as follows:

- Non-coded Signal - Alarm signals produced by a fire alarm system may be continuous sounding throughout the protected area. When these devices are “sounded” continuously, the system is “non-coded”.

- Coded Signal - When devices are sounded intermittently in a prescribed pattern, the system is referred to as a “coded” system. Coded signal systems vary in size, depending upon the size and needs of the alarm system.

Signals can be audible or audible/visible.

Standard 10742

Because public buildings must be accessible to handicapped people, fire alarm system must include visual alarm signals to alert occupants with impaired hearing and in high noise areas by use of a combination horn/light unit. (Refer to American with Disabilities Act guidelines)

The fire alarm system shall comply with requirements of the latest edition of NFPA Standard #72 for Protected Premises Signaling Systems. The system shall be electrically supervised Class ‘A’ Style 6 and monitor the integrity of all conductors.

The system contractor/supplier is responsible for programming (reprogramming) all points at the head end. The point descriptor shall be obtained from the local Wakenhut (G4S) Site Security Manager.

Special suppression systems shall send a signal to the head end on the 1st alarm signal. This signal shall be received as an “alarm” point and not a “trouble” signal.

16.2 Evacuation Systems

Evacuations tomes shall have a sound level at least 15 dB above the ambient sound level or 5 dB above the maximum sound level having a duration of at least 60 seconds whichever is greater, measured 5 feet above the floor. The sound level shall not exceed 115 dB.

Emergency evacuation systems shall be capable of producing three distinct tones:

Fire/evacuation – Provide three (3) 0.5 seconds tones spaced 0.5 seconds apart followed by a 1.5 second pause. This pattern must be repeated for at least three (3) minutes.

Take Cover/Seek Shelter – Provide a continuous bi-tone (high/low) oscillation for at least three (3) minutes.

All Clear/Recall – Provide a continuous signal-tone for at least one (1) minute.

All tones must be manually selectable form the head end. These tones must be distinct and not used for any other plant signaling systems.

The evacuation system's software shall be programmed such that if communication between a field panel and the head end is lost, the field panel while going into the "degrade" mode does not activate the evacuation alarm if a signal is received at the "degraded" panel.

In response to this loss of communication, local Plant Security is required to send a person to monitor the "degraded" panel until repairs have been made and or communications is reestablished with the head end.

This procedure shall be followed when working with a "Class B" system. If the system is a style 6 (or 7) or "Class A" system, then the loss of communication is recorded, but the network panels will continue to function. Alarms can still be received and acknowledged from the panel in the security console room. Repairs shall be made as soon as possible to the system as required.

Exposed wiring for horns and speakers as well as any amplifier boxes must be run in rigid conduit from the device up to the bottom chord of ceiling truss. Wiring may then run in bridle rings or cable trays such that there is nor sagging below the bottom cord of the truss. The distance between bridle rings shall not exceed 10 feet. In office area exposed wire shall be run in IMT up to the suspended ceiling.

Testing of the completed system shall be done with representatives from Plant Engineering, local Plant Security and Corporate. The local authority having jurisdiction (AHJ) involvement shall be determined on a plant by plant basis by local Plant Management. A sound meter shall be utilized for all speaker testing.

Standard 10746

20.0 Hydraulic Fluid Systems

20.1 Hydraulic Fluid Systems - New Installations:

Use an FM approved less flammable hydraulic fluid where possible.

Before purchasing new hydraulic equipment, the manufacturer of the equipment should be consulted to determine if an FM approved less flammable hydraulic fluid could be used in their equipment. Ensure pumps, seals, gaskets, packing and other system components are checked to ensure they are suitable for the approved less flammable fluid to be used.

20.2 Petroleum Based Hydraulic Fluid Systems:

1). Emergency shutoff switches should be provided for shutting down hydraulic pumps in the event of a pipe failure or fire. Switches shall be well marked and readily accessible under any anticipated fire conditions.

2). Flexible hose used for connections should be steel reinforced, designed for the hydraulic fluid being used and capable of withstanding four times the maximum working pressure. Hoses should not rub against other objects as a result of machine movement, vibration, or pressure surges.

3). Avoid using threaded pipe. However, if used, weld joints using a qualified welder following American Welding Society (AWS) or ANSI/ASME procedures. A safety factor of eight over maximum working pressures should be used.

4). Secure/anchor all pipe and tubing to minimize failure due to vibration.

20.3 Fire Protection for Petroleum Based Hydraulic Oil Systems:

Sprinkler protection shall be provided over all hydraulic oil equipment unless written permission is obtained from the Chrysler LLC Corporate Fire Prevention Engineer or GRC. NOTE: Normally this will only occur over a single small hydraulic system associated with a detached operation located in a non-combustible structure and located adjacent to non-combustible occupancy (ignition sources normally not present) and the business interruption potential is low i.e., lost production can be readily made up by other existing equipment and damaged equipment can be readily replaced. A provision for prompt manual shutdown of the system must be provided.

Besides automatic sprinkler protection, the additional degree of protection will depend on two issues – 1). The total quantity of petroleum based hydraulic oil that can be released from hydraulic equipment, assuming that the pumps are not shutoff and 2) the normal presence of ignition sources during operating the equipment such as molten metal, heaters, or other hot surfaces above the auto-ignition temperature of the oil being used, open flames or spark producing equipment, such as welding machines.

As a minimum, provide automatic sprinklers over the hydraulic equipment and at least 20 feet beyond in all directions. Also, provide sprinkler protection for all shielded areas, such as pits beneath equipment or platforms.

Sprinkler protection may be dictated by the surrounding occupancy. Based upon Chrysler LLC Standards, minimum sprinkler design shall be 0.30-gpm per sq. ft. over the most remote 4,000 sq. ft. plus 500-gpm hose stream allowance using 286°F sprinklers.

Portable fire extinguishers (Class ‘B-C’) suitable for flammable liquids fires shall be provided. Provide a minimum of a 10# CO2 or Dry Chemical unit for the area

Standard 10747

For any petroleum based hydraulic oil system(s) with individual reservoirs/tanks containing more than 100-gallons of petroleum-based hydraulic oil or aggregate 100-gallon within 20-feet of individual tanks, an automatic actuated means for shutting down the oil pump(s) and shutting off the flow from accumulators for hydraulic systems may be required.

If required by the Chrysler LLC Corporate Fire Prevention engineer:

Automatic shutdown of the hydraulic system(s) can be best accomplished by using a thermally actuated fire detection system (such as linear heat detection wire) located directly above the hydraulic operated equipment and at least 20 feet beyond in all directions. Interlock the thermally actuated fire detection system with the emergency stop switch or power supply to the oil pump. The thermal detection device should be rated at least 50ºF above the highest anticipated operating environment temperature.

The use of using a sprinkler water flow switch as a method to automatically shutoff the hydraulic system should be discouraged. Same is true for oil reservoir liquid level switches unless it can be proven to activate the power interlock before 25-gallons or less of hydraulic oil are released.

Large Capacity Systems:

Very large (1,000 gallons or greater capacity) petroleum-base hydraulic oil systems should be located in minimum one-hour rated cutoff rooms protected by automatic sprinklers.

20.4 FM Approved Less Hazardous Fluids:

FM approved less hazardous fluids are either of the high water base (oil-in-water emulsion), water-in-oil emulsion, water-glycol, or synthetic types. These are referred to internationally as HF-A, HF-B, HF-C and HF-D fluids respectively.

HF-A fluids contain 90% or more water. They are usually used in light-duty applications –pressure below 1,000 psi using special pumps. Recommended temperature limits are 40ºF to 120ºF.

HF-B fluids consist of 35% to 40% water in mineral oil, with a small amount of emulsifying agent, rust inhibitors and anti-wear additives. Recommended temperature limits are 15ºF to 150ºF.

HF-C fluids consist of 35% to 50% water for fire resistance, ethylene or propylene glycol to improve low temperature properties, and additives for proper viscosity and resistance to corrosion, wear and bacteria. Recommended temperature limits are 0ºF to 150ºF with normal operations at 120ºF to 150ºF.

Most synthetic fluids (HF-D fluids) are one of four types: phosphate esters, chlorinated hydrocarbons, blends of phosphate esters and chlorinated hydrocarbons, and fluids containing other compositions. Recommended temperature limits are 20ºF to 200ºF.

Synthetic fluids are not compatible with natural rubber, Buna, or neoprene seals or hoses. Synthetic fluids also may attack metal protective paints, lacquers and electrical wiring insulation.
