Where exposed electrical conductors are present and, where practicable, clearances no smaller than those given in table 12 shall be provided, between the electrical conductors and all parts of the system that may be approached during maintenance. All nozzles require the installation of a dirt trap comprising 1 side tee, 2 nipples, and 1 pipe cap. Install the nozzle to the nipple on the dirt trap and check the nozzle orifice to ensure proper orientation. Dirt trap lengths should be no more than 10 times nominal pipe diameter.
A false ceiling comprising loose tiles must have the tiles retained within a 6. Nozzles should be a maximum of 12 in. Actuation Installation The method of actuation depends on the system configuration and any specific contract requirements and can be broken down as follows: Single Tank Actuation Multiple Tank Actuation. This will allow removal in the field if necessary. The actuator cannot be removed or tested on site unless fitted with solenoid adaptor part no. Ensure that solenoid is installed between off vertical.
If no other actuators are to be installed, ensure that the actuation cap on the valve is left on. Removable Solenoid Actuator The removable electrical actuator is fitted to the top of the valve assembly as follows: Check the actuator mechanism to ensure that it is in the non-fired position, i.
Remove the actuator cap from the top of the valve assembly see Figure Carefully screw the actuator to the valve assembly see Figure Note: The actuator must be hand tight only. If no other actuators are to be installed ensure that the protective cap on the actuator is retained in position. The Solenoid Actuator is installed with a suppression diode in parallel to the coil as indicated.
End of line monitoring device if required to be installed on site. Before this system is put into operation, the removable solenoid can be checked by firing the system. With power to the actuator, the pin should be firmly in the down position. Before making electrical connection to the actuator, remove from the valve to prevent accidental discharge. Manual Actuator The manual strike knob actuator can be fitted to the top of the electrical actuator or directly onto the valve, after first removing the protective cap.
Before attaching the strike knob to the electrical actuator or valve, ensure that the firing pin is retracted and the safety pin is in place see Figure Pin must be pushed up manually. The strike knob must be hand-tight only. Multiple Tank Actuation Where several tanks comprise one system and are discharged simultaneously, one tank is designated as the master tank, and the others are slave tanks. The master tank can be actuated electrically or manually. The slave tanks are actuated pneumatically by the action of the master tank discharging.
Pneumatic Actuator Check that the actuating plungers are in the raised position see Figure Remove the actuation cap from the top of the valve assembly see Figure 27 and carefully screw the pneumatic actuator to the valve on each slave tank. The actuator must be hand-tight only. Slave Actuation Pilot Line For slave tanks, the pneumatic connection is made using flexible pilot hoses. NPT street elbow Part No. Install the pilot line tee Part No. Connect one end of the pilot hose Part No.
Connect pilot hoses between pilot line tees on all pneumatic actuators see Figure The maximum number of slave actuated tanks is 9 10 tank system in total. Ancillary Equipment Discharge Pressure Switch Single Tank Systems On single tank installations, the pressure switch should be located close to the valve assembly and connected with a pilot hose from the pressure port outlet on the valve to the connector on the pressure switch see Figure Multiple Tank Systems On multi-tank installations, the pressure switch should be located close to the last slave tank and connected by pilot hose to the tee connector on the pneumatic actuator see Figure To wire the discharge pressure switch to the control panel, unscrew and remove the switch cover plate.
Connect to the appropriate terminals on the microswitch or if supplied with wires, to the colored wires which are labeled as follows: Common C Normally Open NO violet blue. Low Pressure Switch All tank valves are 'Factory fitted' with low pressure warning switches. Voltage input can be applied to either terminal. When the device is connected to a standard supervisory input circuit, there will be no distinction between a wiring fault and device actuation.
This device is to only be utilized when accepted by the authority having jurisdiction. Note: In the normal position, the switch contacts are closed. This will indicate a tank pressure above psi If the switch contacts are open, the switch may have been subjected to low temperatures during shipping or storage. To close the switch contacts, the tank must be warmed to a temperature above 70 F 21 C.
This will allow the tank pressure to close the switch contacts. See Figure 46 for field wiring requirements. Accessories Door Signs Warning signs are required at all exits and entrances to protected area, ideally mounted on the door. Plates may be drilled and screw mounted or attached using suitable adhesive. Manual Release Signs Manual release signs are required at all manual actuators, remote manual actuators and call points.
Completion Procedures For ease of reference, completion procedures may be subdivided into the following sections: Pre-Checks and Visual Inspections. Final Connections. Hand over Procedures. In the event of delay between handover and the hazard area being available for protection, then the system must be left in a 'safe' condition to avoid accidental discharge. The system must only be made operative once the area for protection has been completed and is operational.
Pre-checks and Visual Inspections General When the installation is complete, and before making the final connections, the following checks should be made: Mechanical Checks Inspect protected area closely for conformance to original risk specifications and for enclosable openings or sources of agent loss which may have been overlooked in the original specification.
Hazard areas should be thoroughly checked to ensure that enclosures have been properly constructed and that voids in floors and above suspended ceilings have been sealed. Pre-checks and Visual Inspections continued Mechanical Checks continued All manifolds should be secured firmly to the wall or bulk head. Tanks should be securely held within brackets. Piping should be securely mounted within hangers. All pipe connections must be tight. Nozzles to be the proper type, correctly placed, and properly orientated.
Check model and weight markings on tank nameplates to verify that correct tanks and charges have been installed as required. Verify that all warning and instruction signs are mounted where required. Electrical Checks The electrical systems may include interfaces with many other systems for alarm, indication, actuation, shutdown, etc.
For complex electrical systems, the scope and operating requirements will be described in other documents. Electrical checks are given below for a basic system using electrical actuation of the tank valve; Remove top mounted or side mounted solenoid if connected via solenoid adaptor from valve.
Check that solenoid is activated when system is triggered. If the solenoid adaptor is not present, remove electrical connections from side mounted solenoid and check wiring voltage is correct for actuation when system is operated. During detection system actuation, verify the following functions operate; All apertures in hazard enclosure are closed by dampers or other suitable methods.
Electrical equipment in the protected area is tripped and isolated. Pneumatic Checks The slave actuators on manifolded systems are fired by agent discharge. Pneumatic checks are detailed below; Remove pneumatic actuator s from tank valve. Disconnect pilot hose from the master tank valve adaptor see Figure Provide 58 psi 4 bar pressure to the master tank valve pilot hose. Verify all pneumatic actuator pistons are in the fired position. Before replacing the pneumatic actuators, ensure that all pistons are fully reset see Figure After reinstalling the pneumatic actuators, reconnect the pilot hose to the master tank valve adaptor see Figure Final Connections Discharge Piping The final connection of the discharge piping occurs at the tank valve assembly.
For single tank systems, the valve safety outlet cap can be removed and the discharge pipe connected to the tank outlet. For multi-tank systems, the valve safety caps can be removed and all discharge hoses fitted. Handover Procedures The entire system shall be thoroughly inspected to make sure that it is complete and that all tests required during installation have been properly carried out. In addition, the following items are particularly important. Operating pressure of unit at psi 25 bar at 70 F 21 C.
Refer to Appendix B for pressures at other container temperatures. Check tank weight information label against system requirement. If there is any doubt or if there has been a loss of pressure, the tank must be weighed. Make sure the system is armed and the actuating systems are operational.
Ensure adequate escape routes with directional signs are provided. Issue of the appropriate documentation shall constitute completion of the handover procedure. Introduction The hazard integrity is the ability to retain the discharged FM For a total flooding suppression system to be effective, the design concentration must be achieved and then maintained for at least ten minutes.
The only method of testing the agent retention within the protected area is to verify the integrity of the enclosure by applying proven test procedures. The enclosure integrity test has been developed to locate the source of leaks and, from the data collected, predict the retention time, proving system performance and removing the need for actual FM discharge.
In order to determine with any degree of confidence that the hazard area will hold the gas for the required time period, where necessary an Enclosure Integrity Test in accordance with NFPA Appendix C must be conducted.
Like water leaking from the holes in the bottom of a swimming pool, FM tends to escape from leaks in the lower part of the enclosure due to the weight of the mixture above it. The rate at which FM is lost is therefore primarily governed by the leakage below the floor, and walls beneath the ceiling.
This is called the Below Ceiling Leakage Area. Principle The test is conducted with a device known as a door fan, which has been used in the energy conservation field for over 25 years. It has three basic components as follows: An adjustable panel that fits in the doorway of the protected area A calibrated fixed speed fan A variable speed fan The pressure created by the door fan causes the air to move through leaks in the enclosure at high speed making it easy to pinpoint where leaks exist.
A cool chemical smoke or other air current indicator is used to detect the approximate size and location of leaks. Slab to Slab Walls The only major limitation is that it cannot be used to accurately predict a retention time if the perimeter walls do not extend from slab to slab.
The enclosure will almost invariably fail due to extensive leakage through the ceiling tiles. Coordination and Planning It should only be necessary to conduct one integrity test, therefore it is essential to ensure that the enclosure is ready, and that the relevant people have been informed.
Having established that any outstanding works are completed prior to the test date, advise all interested parties in writing, if necessary, outlining the testing method and principles involved. Equivalent Leakage Area ELA The test to measure the ELA is conducted by blowing air into or out of the enclosure to develop the same pressure differential as would be created by the discharging FM By measuring the air flow required, it becomes possible to calculate the ELA, which is the total of all cracks, gaps and holes in the enclosure.
The leakage measurement achieved by taking air out of the enclosure depressurization , and then blowing air into the enclosure pressurization , is then averaged. Integrity Test Procedure Evaluation. The enclosure and immediate surrounding area is initially examined visually to assess the readiness for testing, the existence of any attached spaces that could affect the results, and that there is an adequate relief area and return air path.
The volume of the enclosure is confirmed and the highest equipment measured to ascertain the required level for retention time. All doors outside the area that are required to be open for the test are wedged open with suitable signs posted to advise personnel.
Where voids are protected by FM, tiles are removed to ensure a uniform air flow. The enclosure is put in the state it would be in prior to a discharge, e.
Equipment within the enclosure that does not affect the integrity may be left running to prevent unnecessary disruption and inconvenience.
Self-contained air conditioning unit A self-contained unit conditions the air within the enclosure and does not rely on a fresh air supply, or draw air from other parts of the building.
The concentration will be depleted due to leakage. Therefore the enclosure should be over-gassed to obtain the required ten minute retention time at minimum concentration. The duct volume between the hazard and the damper must be added to the overall volume. Door Fan Installation. A door fan unit is installed in the designated test door in accordance with the manufacturers instructions. The gauges are zeroed by taking them to full scale deflection and holding for approximately ten seconds, after which the gauges are gently tapped and zeroed.
Enclosure Evaluation Static Pressure Measurements. With the door fan equipment fully installed and set up, but with all openings closed, a measurement of any pressure difference between the enclosure and the relief area is made.
If the measurement is unduly high its causes are ascertained and if possible permanently reduced or eliminated. Total Enclosure Leakage Method. The pressure difference, and the air flow required to generate this, is then recorded.
This is carried out for both pressurization and depressurization modes. The total equivalent leakage area and the predicted retention time is calculated. Suspended Ceiling Leakage Neutralization Method. This procedure is used to improve the accuracy of the predicted retention time where a reasonable air-tight ceiling exists, whether or not the ceiling is protected with FM Leak paths through the ceiling may be temporarily sealed.
The volumes above and below the false ceiling are depressurized to the same extent but using separate fans. This is confirmed by using cool chemical smoke to check that no air is flowing through the false ceiling. Readings of the pressure difference between the enclosure, relief area, and the air flow through the fan s used to depressurize the room and false ceiling are made, and then the procedure is repeated in the pressurization mode.
The below ceiling leakage area is then calculated and used in conjunction with the ELA to predict a revised retention time. Calculation A portable computer is used to collate the data and calculate the values. The associated printer provides a detailed hard copy of the data on site. Leakage Location If the enclosure fails the test, or if the client requests, an inspection of the enclosure with the door fan running can be made. This makes it possible to locate the source of any leakage by using cool chemical smoke.
This procedure also tests the efficiency of any dampers, etc. General Comments Personnel required to work in the protected area should be familiar with the detection and suppression equipment installed, and trained in fire procedures. All life-saving equipment must be properly maintained.
The method of system operation is chosen at the design stage to suit the protection required for the hazard area and the environmental factors appropriate to that area. This part of the document provides information relevant to ALL the standard operational systems to cover the eventuality of changes to, or expansion of the original design. Fully Automatic System Where a sensitive fire detection system is included for the automatic release of extinguishing agent, the system shall only be capable of automatic release once two or more sensors detect the fire.
The number of detectors and their spacing is designed to ensure a satisfactory response time. To ensure personnel may safely evacuate the risk area, an adjustable time delay should be fitted such that sufficient time may elapse prior to system discharge.
Ideally, the delay period shall not exceed 30 seconds. Prior to system discharge and at the commencement of any time delay period a clearly audible alarm different from any other used shall sound and continue until the complete system is reset.
In areas of high ambient noise level, a visual indication may also be required, in addition to the audible warning. The design of a system for automatic detection, signal distribution, alarms, etc. Therefore, details appertaining to fire detection and alarm operation and maintenance are not included in this document. The arrangement of systems is large but from an operational point of view, the systems are best grouped as: Manual. Fully Automatic.
Automatic with Manual Intervention. Manual System Manual systems depend on human detection of a fire in the hazard area and prompt action to actuate the local or remote strike knob for the FM system to discharge and flood the protected area and suppress the fire.
All other instructions associated with manual operation form part of the users procedures on safety precautions and fire drill. If required, Pyro-Chem can assist the user to prepare the procedures for safety and fire precautions. Fully Automatic System with Manual Intervention Manual intervention of an automatic system may be included for the following condition: Where personnel are required to work within the protected area.
In protected areas where personnel are present and the concentration is greater than NOAEL, it is recommended that the automatic feature of the system is isolated during occupation. This may be achieved either by an electrically contacted lock assembly or by a clearly marked key switch at a suitable location outside the risk area.
Conditions During a Fire The users fire and safety instructions to personnel should include advice on the conditions prevailing during the discharge of an FM system. This advice is intended to prepare the personnel for the situations likely to arise and therefore minimize the risks of panic. Three major conditions prevail during FM discharge of which personnel should be made aware:.
Actions Following a Fire General These notes are only applicable to the hazard area s protected by a FM fire suppression system. Where such a system may form part of, or combine with other forms of fire protection systems, then composite instructions for all systems are necessary to ensure the safety of personnel and property following a fire.
Pyro-Chem is available to assist in preparing composite instructions. A normally occupied area is designed as an area intended for occupancy. Any area protected by FM should be evacuated prior to start of system discharge.
Actions Immediately Following a Fire These actions should, at a minimum, include the following: Advise the emergency services, Fire, Accident, Police, if appropriate. Organize a roll-call of employees and any visitors. Prevent unauthorized personnel from entering the hazard area.
In the case of deep seated fires, the hazard space should be kept tightly closed for at least 60 minutes after discharge of the FM extinguishing agent. It is essential that the fire be completely suppressed before ventilating the space. Before permitting anyone to enter the space, ventilate thoroughly or ensure self-contained breathing equipment is used. Do not enter the hazard area in which fire has been suppressed with an open flame or lighted cigarette as the possible presence of flammable vapors may cause re-ignition or explosion.
Should it be necessary to enter a space containing FM or decomposition products, the following precautions should be taken: Use a fresh air mask or self-contained breathing equipment. Do Not use a filter mask or canister-type mask. Do Not enter space unless you are under observation from outside the space, or tethered by a lifeline.
Ensure that all pressurized equipment is isolated or safe from release. FM decomposes when exposed to temperatures exceeding F C , such as flames, hot metal surfaces, etc.
The rate of this decomposition is dependent upon the size of the area where extreme temperatures are found, and also upon the length of FM exposure time. To avoid decomposition, Pyro-Chem systems are designed to discharge and suppress the fire quickly. The average duration of discharge for these systems at 68 F 20 C is less than 10 seconds, so the minimum amount of decomposition occurs.
Hydrogen Fluoride is the most toxic decomposition product. This material generates a sharp acrid odor, which is easily detected and acts as a warning and a good safeguard to personnel. FM Discharge Conditions FM has low boiling point, consequently the discharge is very cold at the point where it leaves the nozzle.
Care should be taken to avoid working within 3 ft. The velocity of discharge of FM from a discharge nozzle is very high. Care should be taken to insure that objects which may become dangerous projectiles are secured or removed from the hazard area. Introduction This section provides user inspection and maintenance guidance for FM Engineered Systems. A log book will be provided to record all inspections, maintenance, measurements and actions taken. The continued capability for effective performance of an FM Total Flooding Fire Suppression System depends on fully adequate maintenance procedures, with periodic testing.
Reference NFPA section to Weekly Check of System Components Make a visual inspection of the system components, distribution piping and nozzles. Check the immediate vicinity of all equipment to ensure that no accidental damage or tampering has occurred. Weekly General Check Inspect the hazard area, access routes, tank storage area, floor voids and areas above suspended ceilings to ensure housekeeping is good and that no refuse has accumulated.
Ensure that access to the system tank assemblies and local remote controls is unobstructed. Monthly Check of Signs Inspect system and protected spaces to ensure that warning signs, safety precautions and operating instructions are posted and clearly visible. Monthly Personnel Training Check Check that all personnel who may have to operate the equipment or system are properly trained and are authorized to do so, and in particular that new employees have been instructed in its use.
User's Program of Inspection The installer should provide the user with an inspection program for the system and components. The program shall include instructions on the action to be taken in respect of faults. The user's inspection program is intended to detect faults at an early stage to allow rectification before the system may have to operate.
A suitable program is as follows: Weekly Check of Hazard Area Inspect the hazard area against the original layout to ensure that there have been no changes that might affect the proper performance of the fire protection system. Changes might include: Contents of area. Use of area. Air Handling equipment in area. Openings in area. Weekly Check of Tanks Check storage tank pressure gauges and ambient temperature, compare these pressures to the Temperature Correction Chart to determine temperature corrected pressure.
All measurements and actions shall be recorded in the log book. Before any checks are carried out, ensure the extinguishing system is isolated electrically and mechanically and remove all solenoid and pneumatic actuators. No maintenance work should be carried out without obtaining approval from the Fire Safety Director and advising any personnel within the hazard area.
The following Program should be carried out in addition to the User's Program of Inspection. The user shall be provided with a signed and dated report of the inspection advising any rectification carried out or needed. Test and service all actuating mechanisms. Check tank labels are securely fixed and legible. Check tank brackets and fittings. Verification of the content of FM in the tanks may be achieved through either liquid level detection or tank weighing.
Tank Weighing Where a Client does not wish to use a Pyro-Chem maintenance contract or the specialized liquid level detection equipment, then tanks must be weighed to establish the FM content. The weighing procedure is as follows: Remove all manual controls, pressure actuators and pressure actuation pipe or tubing and flexible electrical connectors.
Install Safety Outlet Caps onto tank valves. Remove tanks from bracketing and weigh tanks. Any tank showing more than the maximum allowable weight loss must be recharged by a qualified recharge agent. Record weight of tank on record tag. Replace tanks in bracketing and remove Safety Outlet Caps. Operation To measure the liquid FM level: 1. Remove the protective cap from the measuring device housing.
Lift the measuring tape to the end or approximately 3 in. Slowly lower the tape until a magnetic interlock is felt see Figure Read the measurement on the tape directly at the top of the plastic sleeve in the measuring device housing see Figure Record this measurement and note the temperature of the tank module. The tank module temperature can be determined by measuring the ambient temperature at the tank location.
The tank must be stored at this temperature for at least 24 hours to obtain an accurate liquid level reading. Using the Liquid Level Measuring Device The Pyro-Chem liquid level measuring device is used to determine the liquid FM level in , , and liter storage tank assemblies. During a maintenance examination, the measuring device will enable a service representative to convert a linear measurement to agent weight in order to determine if the tank has any weight loss.
This measurement is accomplished without removing the FM tank from the fire suppression system. To reinstall tape, quickly pull on the tape to disengage the magnetic interlock. Then slide the tape into the housing and replace the protective cap.
Find the liquid level reading along the left hand vertical line of the table. From that point, follow the horizontal line to the point where it intersects with the temperature column using the FM tank temperature noted in Step 3. Compare the weight from the table to the weight of charge stamped on the tank nameplate. The temperature of the tank is 60 F 16 C. Replace whole unit where appropriate. Check all control valves for correct manual function and automatic valves additionally, for correct automatic function.
Replace or pressure test and repair as necessary pipework showing corrosion or mechanical damage. If drawings are not available and this is the first visit, then dimensions should be taken and passed to the engineering department together with the quantity of agent to enable a calculation to be carried out to ensure the correct quantity of gas has been used.
If visual examination shows any deficiency, the hose shall be replaced. Personnel Training All persons who may be expected to inspect, test, maintain or operate the fire suppression system shall be kept adequately trained in the functions they are expected to perform. Personnel working in an enclosure protected by a gaseous extinguishant shall receive training in the operation, use of the system and safety issues.
Mechanical Servicing Procedure a. Remove valve actuator s where possible from the tank valve s and replace actuation cap s.
Disconnect pneumatic valve actuators from the slave tank valves and install actuation caps. Disconnect the pilot loop from the master tank valve and install the appropriate plug. Introduce 58 psi 4 bar pressure into the pilot actuation line to the pneumatic actuators. Check that the pistons in the pneumatic valve actuators have fully fired. Before installing the pneumatic actuator onto the tank valve, ensure that the piston is reset. This section only applies if: 1 Pyro-Chem distributor is performing the maintenance on the detection system.
When this test is performed, the release circuit of the detection system must operate the electric actuators causing the plungers to be firmly extended. If Pressure switch es have operated, check that connected devices have activated or shut down as required and reset. Finally Perform a final visual inspection of the system and the protected area to ensure that all equipment has been reinstalled and reconnected properly.
Complete the site log book, recording work completed and parts used. Inform the responsible person that the work is complete and that the system is back on-line. Recharging This section describes the procedures required to enable the refilling of a tank that has been discharged and will require recharging.

Also, remove the schrader valve from the top cap 3 in. Remove the O-Ring below the top cap. Replace with new O-Ring in a later step. Remove the shuttle from the valve body. The shuttle contains two O-Rings. First, remove the upper O-Ring and replace with a new, lubricated O-Ring.
Remove bottom cap from shuttle and replace O-Ring with lubricated O-Ring. Clean inside surfaces of valve body. Be careful not to scratch surface. Spray a small quantity of PTFE silicone grease into the bore of the valve body. Install bottom cap to shuttle, using Loctite , and return shuttle to inside of valve body not required for 3 in valve.
Install new lubricated O-Ring into valve body groove for top cap seating surface or unto top cap for 1 in. Valve Teardown After a discharge, the valve assembly must be disassembled, cleaned, O-Rings replaced, burst disc replaced, if necessary, and tested.
See Figure 1 or Figure 2 for component description. Check to make certain the tank contains no pressure. Do this by weighing the tank and comparing the weight with the stamped weight; Visually determining the pressure gauge reads zero; and also carefully look into the valve outlet. If the shuttle is above the top of the outlet, the cylinder is empty and contains no pressure. If the shuttle is below the outlet, the tank still contains pressure and must be properly bled down before proceeding.
Remove valve from tank. Loosen set screw on valve and remove siphon tube. Siphon tube for L tank stays in the tank collar. Install new schrader valve, torque to 5. Pyro-Chem Wet Chemical Solution.
