[F] AUTOMATIC FIRE-EXTINGUISHING SYSTEMAn approved system of devices and equipment which automat-ically detects a fire and discharges an approved fire-extinguish-ing agent onto or in the area of a fire

[F] AUTOMATIC SPRINKLER SYSTEM A sprinkler sys-tem for fire protection purposes is an integrated system of un-derground and overhead piping designed in accordance withfire protection engineering standards The system includes asuitable water supply The portion of the system above theground is a network of specially sized or hydraulically de-signed piping installed in a structure or area generally over-head and to which automatic sprinklers are connected in asystematic pattern The system is usually activated by heatfrom a fire and discharges water over the fire area

[F] AVERAGE AMBIENT SOUND LEVEL The root meansquare A-weighted sound pressure level measured over a24-hour period

[F] CARBON DIOXIDE EXTINGUISHING SYSTEMSA system supplying carbon dioxide (CO2) from a pressurizedvessel through fixed pipes and nozzles The system includes amanual- or automatic-actuating mechanism

[F] CEILING LIMIT The maximum concentration of anair-borne contaminant to which one may be exposed as pub-lished in DOL 29 CFR Part 19101000

[F] CLEAN AGENT Electrically nonconducting volatile orgaseous fire extinguishant that does not leave a residue uponevaporation

[F] CONSTANTLY ATTENDED LOCATION A desig-nated location at a facility staffed by trained personnel on acontinuous basis where alarm or supervisory signals are moni-tored and facilities are provided for notification of the fire de-partment or other emergency services

[F] DELUGE SYSTEM A sprinkler system employing opensprinklers attached to a piping system connected to a water sup-ply through a valve that is opened by the operation of a detec-tion system installed in the same areas as the sprinklers Whenthis valve opens water flows into the piping system and dis-charges from all sprinklers attached thereto

[F] DETECTOR HEAT A fire detector that senses heat pro-duced by burning substances Heat is the energy produced bycombustion that causes substances to rise in temperature

[F] DRY-CHEMICAL EXTINGUISHING AGENT Apowder composed of small particles usually of sodium bicar-bonate potassium bicarbonate urea-potassium-based bicar-bonate potassium chloride or monoammonium phosphatewith added particulate material supplemented by special treat-ment to provide resistance to packing resistance to moistureabsorption (caking) and the proper flow capabilities

[F] EMERGENCY ALARM SYSTEM A system to provideindication and warning of emergency situations involving haz-ardous materials

[F] EMERGENCY VOICEALARM COMMUNICA-TIONS Dedicated manual or automatic facilities for originat-ing and distributing voice instructions as well as alert andevacuation signals pertaining to a fire emergency to the occu-pants of a building

[F] EXPLOSION An effect produced by the sudden violentexpansion of gases that is accompanied by a shock wave or dis-ruption of enclosing materials or structures or both

[F] FIRE ALARM BOX MANUAL See ldquoManual FireAlarm Boxrdquo

[F] FIRE ALARM CONTROL UNIT A system componentthat receives inputs from automatic and manual fire alarm de-vices and is capable of supplying power to detection devicesand transponder(s) or off-premises transmitter(s) The controlunit is capable of providing a transfer of power to the notifica-tion appliances and transfer of condition to relays or devices

[F] FIRE ALARM SIGNAL A signal initiated by a firealarm-initiating device such as a manual fire alarm box auto-matic fire detector water flow switch or other device whoseactivation is indicative of the presence of a fire or fire signature

[F] FIRE ALARM SYSTEM A system or portion of a com-bination system consisting of components and circuits ar-ranged to monitor and annunciate the status of fire alarm orsupervisory signal-initiating devices and to initiate the appro-priate response to those signals

[F] FIRE COMMAND CENTER The principal attended orunattended location where the status of detection alarm com-munications and control systems is displayed and from whichthe system(s) can be manually controlled

[F] FIRE DETECTOR AUTOMATIC A device designedto detect the presence of a fire signature and to initiate action

[F] FIRE PROTECTION SYSTEM Approved devicesequipment and systems or combinations of systems used to de-tect a fire activate an alarm extinguish or control a fire controlor manage smoke and products of a fire or any combinationthereof

[F] FIRE SAFETY FUNCTIONS Building and fire controlfunctions that are intended to increase the level of life safety foroccupants or to control the spread of harmful effects of fire

[F] FOAM-EXTINGUISHING SYSTEM A special systemdischarging a foam made from concentrates either mechani-cally or chemically over the area to be protected

[F] HALOGENATED EXTINGUISHING SYSTEM Afire-extinguishing system using one or more atoms of an ele-ment from the halogen chemical series fluorine chlorine bro-mine and iodine

[F] INITIATING DEVICE A system component that origi-nates transmission of a change-of-state condition such as in asmoke detector manual fire alarm box or supervisory switch

LISTED Equipment materials or services included in a listpublished by an organization acceptable to the building officialand concerned with evaluation of products or services thatmaintains periodic inspection of production of listed equip-ment or materials or periodic evaluation of services and whoselisting states either that the equipment material or servicemeets identified standards or has been tested and found suitablefor a specified purpose
