Model RPS-M Remote Mechanical Pull Station _/ General Paint spray booths/rooms are areas designed to confine or limit the escape of spray, vapor, and residue. A power ventilation sys- tern dedicated to these areas ensures the appropriate exhaust of residual material. Pyro-Chem's dry chemical extinguishing agents are appropriate for Class A, B, or C fires. A caI9fuI hazard survey should be conducted to properly define the type of fire to be extin- guished. In addition to flammabIeIcombustibIe liquids, the material composition of the object to be painted must be considered as well as resident material in the protected area. Total flooding and local application fire extinguishing techniques as defined by NFPA 17 are utilized by Pyro-Chem's Monarch TN fire suppression systems to protect the entire hazard which includes the work area, exhaust plenum area, pits, under fIoor's and exhaust ducts. The National Fire Protection Association Standard No. 33 .Spray Application Using Flammable and Combustible Materials. and No. 17 .Dry Chemical Extinguishing Systems. are primary reference sources and provide guidelines for the proper application and design of Pyro-Chem's Monarch TN Industrial Fire Suppression Systems in the specialized protection of paint spray booths and rooms. Underwriters Laboratories testing provides pre-engineered system application parameters allowing the flexibility to protect a variety of paint spray booth/room layouts to Underwriter's Standard Ul1254, effective September 1998, with confidence.

It pro- vides a highly reliable response with the versatirlty of automatic or manual activation. A modular concept of protection is used. A nozzJe with a prescribed area of protection and positioned according to pre-engineered placement parameters protects a modular area of hazard. Sets of nozzles supplied by a dedicated cylinder containing dry chemical extinguishing agent and piped in an approved pattem consistent with the application coverage are utilized. Mechanical or electrical fixed temperature thermal detectors are positioned strategically within the protected area to monitor ambient temperature and ini- tiate an output should the rated temperature be exceeded. The detector input is .sensed" at the control head. The control head responds by discharging the system by pneumaticalJy depressing the stored agent cylinder valve. The system is provided with a time delay device to allow for fan shut down before agent discharge. A manual means of activating the system is also provided. Expanded capability is available to provide remote manual activa- tion, auxiliary electrical outputs and/or audible a1anns. This option_ al equipment will enhance the basic system functions and be applicable when designing custom configurations to suit a particu- lar custornets needs and/or comply with local codes.
