• • • • December 2008 Section 1 General Information Page 1 —5 • Amerex Restaurant Fire Suppression System (EX 4658) • LISTED: Equipment, materials, components and parts included in a list published by an organization • acceptable to the AHJ (Authority Having Jurisdiction) and concerned with product evaluation, which maintains • periodic inspection of production of listed equipment or materials and whose listing states either that the equipment or material meets appropriate standards or has been tested and found suitable for its use in the • specified manner. The listing may not be considered valid unless so labeled. • MAINTENANCE: A"thorough check" to give maximum assurance that the extinguishing system will operate • as intended. Design parameters should be closely examined for hazard changes since the last inspection, • parts and components should be closely examined and tested or replaced if necessary. • MAKE-UP AIR: Air that is brought into the hazard from outside of the area, using a dedicated fan, to aid in • the exhaust of grease-laden vapors. • MANUAL PULL STATION: The device that allows the system to be manually discharged either at the hazard • or from a remote location. MECHANICAL RELEASE MODULE (MRM /MRM II): An assembly that connects and controls the actuation • cartridge, the detectors, the manual pull station(s), the gas valve, the micro-switch(es) and the agent cylinder/discharge valve(s). It receives inputs and activates appropriate outputs — including agent release, auxiliary signals and power or gas shut-off. • SNAP ACTION SWITCHES: A set of dry (unpowered) electrical contacts arranged in various configurations • for initiating appropriate output functions such as signal to the building fire alarm, audible/visual remote signal, electrical power shut-off, electric gas valve shut-off. • NOZZLE: The device used to deliver a specific quantity, flow and discharge pattern of fire suppression agent • to a specific appliance, duct size or plenum size. • NOZZLE BRANCH LINE: All pipe and fittings leading from the supply branch tee to a system nozzle. • OUTPUT: An action that is initiated by the mechanical release module in responding to a pre-determined input. (Examples: Agent release, power shut-off, remote signal, gas valve closure) • PERIMETER INCHES: The sum of the measurement of each side of a rectangular duct opening. (Example: • Duct opening measuring 18"x 9"would have 54 perimeter inches[18 + 18+ 9+ 9=54]) • PLENUM: The space defined by the filters and the portion of the hood behind the filters. 41 • PNEUMATIC RELEASE MODULE (PRM): This single hazard control mechanism supervises and controls one Fire Suppression System. Proven, rugged mechanical components are reliably set into motion with a simple linear pneumatic detection interface. The control mechanism interfaces with mechanical manual pull station(s), actuation networks, mechanical gas valves, and offers electrical contacts for shutdown functions. • Refer to the Design and Installation Manual, P/N 16546 for further details. • PRE-ENGINEERED SYSTEM: Those systems having pre-determined flow rates, nozzle pressures and • quantities of agent These systems have the specific pipe size, maximum and minimum pipe lengths, flexible • hose specifications, number or fittings and number of types of nozzles prescribed by a testing laboratory. The hazards protected by pre-engineered systems are specifically limited as to type and size by a testing • laboratory based on actual fire tests. Limitations on hazards that can be protected by these systems are • contained in the manufacturer's installation manual, which is referenced as part of the listing. • "PUFF TEST" (or"AIR TEST"): A test to determine that the distribution network piping is clear. The test is • conducted by running nitrogen through the piping and confirming that all nozzles are clear. • PULLEY TEE: A device similar to a corner pulley except there is a change in direction on the cable from two • manual pull stations or two mechanical gas valves. It unites either two gas valves or two manual pull stations to a single control point. •
