"Fixed fire extinguishing system" means any fire-fighting system employing a suppression agent, which shall be a currently recognized agent or water additive, with the purpose of controlling, suppressing or extinguishing a fire in a specific hazard and that falls within the scope of the following National Fire Protection Association (NFPA) standards:
(a) NFPA 12, Standard for Carbon Dioxide Extinguishing Systems;(b) NFPA 12A, Standard for Halon 1301 Fire Extinguishing Systems;(c) NFPA 17, Standard for Dry Chemical Extinguishing Systems;(d) NFPA 17A, Standard for Wet Chemical Extinguishing Systems;(e) NFPA 750, Standard on Water mist Fire Protection Systems; and(f) NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems.The term includes engineered and pre-engineered fire suppression systems as defined below:
(a) "Engineered fire suppression system" means any fire suppression system having pipe lengths, number of fittings, numbers and types of nozzles, type and quantity of suppression agent, suppression agent flow rates and nozzle pressures as determined by calculations derived from the applicable standards of the National Fire Protection Association (NFPA), whether those calculations are performed by hand, by a computer program or by another method of calculation. These systems may consist of other components, including detection devices, alarm devices and control devices as tested and approved by a nationally recognized testing laboratory and shall be listed as compatible with the fire suppression system involved; or(b) "Pre-engineered fire suppression system" means any fire suppression system having predetermined flow rates, nozzle pressures and quantities of a suppression agent and having the specific pipe size, maximum and minimum pipe lengths, flexible hose specifications, number of fittings and number and types of nozzles prescribed by a nationally recognized testing laboratory. The hazards protected by these systems are specifically limited as to the type and size by the testing laboratory based upon actual fire tests. Limitations on hazards that can be protected by these systems are contained in the manufacturer's installation manual, which is referred as part of the listing.N.H. Admin. Code § Saf-C 1202.04
