INPUT: An event monitored by the Mechanical Release Module (MRM or MRM II) or Pneumatic Release
Module, which causes a corresponding output(s). (Example: A detector senses fire [input] and the system
discharges [output] and trips the gas valve [output]).
INSPECTION: A “quick check” to give reasonable assurance that the system has not been tampered with.
LINEAR ACTUATOR (P/N 24448): The Linear Actuator is a device that, when electrically activated, extends a
metal shaft to mechanically open agent cylinder (with an electric actuation option) in the AMEREX® KP™ Fire
Suppression System. The Linear Actuator connects to the end of an actuation circuit and is color coded yellow.
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.
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.
