The fire suppression system shall include and not be limited to gas release control panel, CCE approved seamless cylinders, discharge valve (with solenoid or pneuma -tic actuator) as the case may be, discharge pipe, non-return valve and all other accessories required to provide a complete operation system meeting applicable requirements of NFPA 2001 or ISO standards and installed in compliance with all applicable requirements of the local codes and standards. The system design should be based on the specifications contained herein, NFPA 2001 & in accordance with the requirements specified in the design manual of the agent. The bidder shall confirm compliance to the above along with their bid.

2.3.1.6.2.3 Design and Engineering:

FM 200 systems shall be designed taking the minimum design concentration of 6.25% (0.485 gm/m3) as applicable to class ‗A‘ & ‗C‘ risks. The system design must consider the limitations caused by the void height. It should also consider temperature in the void. The qualifying bidder should clearly indicate the qty. of the gas in Kgs. to be used for the system. All voids within each hazard shall be discharged simultaneously. Each hazard shall have an independent system, unless otherwise specifically stated, when a centralized system with directional valves can be used. FM 200 systems shall have a working pressure of 25 bar. A fill density between 0.56 Kg / lt. to 0.85 Kg/lt. should be considered for the agent to be discharged within the specified time of 10 seconds maximum. The system engineering company should carry out the piping Isometric design and validate the same with a hydraulic flow calculation generated by using the agent's design software. The appropriate fill density shall be arrived based on the same. The design & calculation shall be checked & certified by Manufacturer. The calculation is the only guarantee that the system will work, provided the system is installed exactly as per the design. The contractor has to take into consideration the routing available while designing the pipe network. A certification (from the manufacturer of the agent or their direct distributor) on the authenticity with gas chromatography and quality of the agent filled in the system procured should be submitted by the system engineering company.

2.3.1.6.2.4 Refilling and Maintenance:

In case of any leakage or accidental discharge of the agent, it should be possible to refill the cylinders in India itself. The contractor should

indicate the source of refilling and time that will be taken for refilling and replacement. 2.3.1.6.2.5 Discharge Time:

As gas has to be fully discharged within 10 seconds for effective quenching of fire as per the relevant standards, the contractor has to ensure that the design meets this requirement. Once the discharge takes place there should be warning signs restricting personal from entering the protected area until the gas has been cleared from the area.

2.3.1.6.2.6 Materials and Equipments:

All materials and equipments shall be from approved manufacturers and shall be suitable for the performance of their respective functions. The cylinders should be complete with all accessories. The contractor shall indicate the dimensions of the cylinders required for each area while quoting.

2.3.1.6.2.7 Cylinder:

The cylinder shall be high pressure, seamless steel gas cylinder, flat type, concave bottom as per IS 7285 complete with neck ring welded and cylinders without CCE approval shall not be accepted. The maximum fill density of FM 200 in a cylinder shall not be less than 0.56 kg/lt. and not exceed 0.85 Kg/lt. of internal volume. Appropriate fill density shall be chosen based on the cylinder location and piping retrofit. The hydraulic calculations should prove that the fill density is appropriate and total discharge will take place within 10 seconds. The cylinders shall be super-pressurized with dry nitrogen to 25 bar at 20°C. The cylinder shall be capable of withstanding any temperature between -30° C and 70°C. Cylinder shall be mounted according to manufacturer recommendations. The cylinder shall withstand Hydrostatic test pressure up to 250 bar and maximum working pressure at 15°C shall be 150 bar. The discharge valve shall be approved or listed for use with FM 200. All the gaskets, O-ring, sealant and other valve component shall be constructed of materials compatible with the clean agent. The system should be engineered using hardware approved for use with FM 200 systems. This would include main discharge valve, solenoid, check valve / non-return valve and pneumatic actuators.

2.3.1.6.2.8 Pipes & Fittings:

All Pipes shall be of ASTM - A-106, Gr: B, schedule - 40 seamless mild steel pipes and fittings shall be as per ASTM-A-105 standard.

2.3.1.6.2.9 Discharge Nozzle:

Nozzle shall control the flow of FM 200 to ensure high velocity, proper mixing in the surrounding air and uniform distribution of the agent throughout the enclosure. The number of nozzles and their positions must be chosen so that the design concentration is maintained everywhere in the enclosure. Nozzle shall be located where they can be adequately supported on walls, ceiling or structural members. Software generated calculation supporting the nozzle design shall be submitted by the successful bidder before signing of contract.

2.3.1.6.2.10 Documentation:

The system engineering company should prepare & submit along with the bid documents, the piping Isometric drawing and support the same with a hydraulic flow calculation generated by using the agent's design software. The calculations shall validate the fill density assumed by the bidder. The bidder shall submit copies of the datasheets of the hardware used in the system. The bidder shall also submit copy of CCE approval letter for the cylinder proposed to be used. These documents shall be attached to the bid. The bidder shall also submit calculations to evidence the qty of agent considered for the system. The qualifying bidder must submit, along with the supply invoice, a certificate of authenticity, for the agent from the system engineering company duly checked and verified by distributor.
