Acronym for Aqueous Film Forming Foam. A synthetic foam
concentrate containing detergent and fluorocarbon surfactant
that forms a foam capable of producing a vapor-suppressing
aqueous film on the surface of some hydrocarbon fuels. It
provides rapid flame knockdown on short preburn, shallow spill
fires (e.g. aircraft crash fires), but is not suited for use on long
preburn, deep-seated fires (e.g. storage tank fires).
An alarm indicator (sound, light, bell, etc.) that signals the alarm
status of alarm devices in the security system.
Activating or enabling the alarm system. See Disarm.
A sound generating alarm device such as a siren, bell, or horn
used to indicate an alarm condition.
Disabling or deactivating a zone of a security system.
Deactivating or disabling the alarm system.
A high decibel alarm signaling device that uses a spring driven
striking mechanism upon an outer bell (as compared to a siren
or electronic alarm signal).
Fire Alarm Pull Station
A device that permits crewmembers to manually actuate the
fire alarm system.
A system containing either or both a smoke detector and heat
detector (see Smoke Detector, Heat Detector).
A hand held device containing an agent capable of extinguish-
ing small fires.
A device used to direct firefighting water to extinguish fires that
might not be accessible with portable hoses and nozzles.
Fixed-Temperature Heat Detectors
A fire detection device that triggers an alarm when the tem-
perature at the detector reaches a pre-set limit.
Chemically known as heptafluoropropane, FM-200 is a clean
agent alternative to Halon 1301 which NFPA 2001 accepts for
use in total flooding situations where human exposure is ex-
pected. FM-200 contains no ozone depleting chlorine or bro-
A fire detection device that detects the heat from a fire and
triggers an alarm and/or a water sprinkler system.
Acronym for hydrogen fluoride gas. This poisonous gas is
formed when FM-200 fire suppression agent contacts hot flame
