fire department connectionnormally on exterior of building... FDNY can pump supplemental water into the sprinkler system, standpipe, or other system furnishing water for fire extinguishment to supplement existing water supplies.
system control valve valve controlling flow to water-based fire protection systems.
fire command center Designated room or area in a structure where the status of the fire detection, alarm, and protection systems is displayed and the systems can be manually controlled.
Fire pump, automatic standpipe. A fire pump located at or below street level that supplies the lower 300 feet (91.4 m) of a standpipe system or a combined standpipe and sprinkler system.

OS & Y valve indicating type of control valve used for fire sprinkler system
deluge valvewater supply control valve intended to be operated by actuation of an automatic detection system that is installed in the same area as the discharge devices. INTENDED USE IS MANUAL AND AUTO
deluge sprinkler systememploying open sprinklers that are attached to a piping system that is connected to a water supply through a valve that is opened by the operation of a detection
system installed in the same areas as the sprinklers. WHEN IT OPENS, water flows into the piping system and discharges from all sprinklers attached. Early suppresion fast response sprinklersfast response sprinkler that is listed for its capability
to provide fire suppression of specific high challenge fire hazards
extra large orifice sprinklers = or > 1 inch less pressure to achieve a given discharge density
extended coverage sprinkler 400 max square feet discharge 20 foot by 20 foot spacing between sprinklers
fire pumpa provider of liquid flow and pressure dedicated to fire protection. A fire pump is
a part of a fire sprinklers system water supply and can be powered by electric, diesel or steam. connected to public water source or tank. provides higher pressure to sprinkler system
Glass bulb sprinkleroperated by heat breaking a glass bulb filled with a non freezing liquid with diameters that vary form 3 mm for quick response to 5 mm for standard response

hydraulic placardsign attached to a hydraulically calculated sprinkler system indicating the design density, required gallons per minute and pressure for the system to operate properly
hydraulically calculated systemsmethod of sizing auto sprinkler piping using a prescribed
amount of water to be distributed over a specific area.
impairment coordinatorin charge of safety during out of service systems
intermediate level sprinklersprinkler equipped with integral shields to protect the operating
elemtn form discharge from sprinklers installed at higher elevations
large orifice sprinkler sprinkler head with orifice size equal or greater than 3/4 and less than 1
inch
listed deviceA fire protection component that has been tested to perform under parameters specified for its use by a nationally recognized testing agency. Underwriter's Laboratory (UL) and Factory Mutual (FM) are the two most common.
Master Pressure Reducing ValveA pressure reducing valve installed to regulate pressures in
an entire fire protection system and/or standpipe system zone.
Main DrainThe primary drain connection located on the system riser and also utilized as a flow test connection.
Microbiologically Influenced Corrosion (MIC)Corrosion caused by the presence of microbes in the water supply that over time attack the interior of metallic piping and cause leaks, pitting, and blockages. Old-Style/Conventional Sprinkler A sprinkler that directs 40% to 60% of the water initially in a downward direction and is designed to be installed with the deflector in either the upright or
pendent position.
Pendent SprinklerA sprinkler designed to be installed in such a way that the water stream is directed downward against the deflector.
Pintle Screws A visual indicating device required for sprinklers manufactured prior to 1999 identifying small orifice sprinklers and large orifice sprinklers where orifice size is different than the nominal thread size of the sprinkler head.
Pipe Schedule SystemsA method of sizing piping based upon the number of sprinkler
heads and the occupancy of the protected area.
Preaction Sprinkler SystemA sprinkler system employing automatic sprinklers that are attached to a piping system that contains air that may or may not be under pressure, with a supplemental detection system installed in the same areas as the sprinklers.
Pressure Control ValveA pilot operated pressure reducing valve that may be used with a fire or booster pump designed for the purpose of preventing the incoming water supply pressure from dropping below a set pressure.
Pressure-Reducing ValveA valve designed for the purpose of reducing the downstream
water pressure under both flowing (residual) and nonflowing (static) conditions.
Pressure Relief Valve A valve designed for the purpose of releasing excess air or water pressure
from the Fire Protection Piping System.
Pressure Tank A tank using air pressure to supplying water for water-based fire protection
systems. Tank contents to be maintained at one third air to two thirds water.
Quick Response Sprinkler HeadA sprinkler having a fusible link with a response time index
(RTI) of 50 or less.
Recessed SprinklerA sprinkler in which all or part of the body, other than the shank thread, is
mounted above the ceiling.
Residential Sprinkler A type of fast response sprinkler that has been specifically tested to enhance survivability in the room of fire origin and listed for use in dwelling units.
Response Time Index (RTI) A measurement of the thermal sensitivity of a sprinkler head expressed in (meters-seconds) 1/2.
Supervisory signalA signal indicating the need for action or the use of such device in connection with the supervision of fire alarm systems or the maintenance features of related systems.
