SPRINKLER SYSTEMS
Fire department connection - answers -normally 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 - answers -valve controlling flow to water-based fire protection
systems.
Fire command center - answers -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. - answers -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.
Tags - answers -on closed section valves serving affected areas: area affected, brief
description, occupancy classification, c of f number, estimated time until operational
Green tag - answers -no impairment found in entire system- main control valve
Red tag - answers -place on main control valve if fully out of service... Put sprinkler
company name, date of removal from service and anticipated time to operational
Blue disk - answers -partially out of service- on all fire department connections
Water storage tank - answers -collects cooled water
Os & y valve - answers -indicating type of control valve used for fire sprinkler system
Deluge valve - answers -water 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 system - answers -employing 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 sprinklers - answers -fast response sprinkler that is
listed for its capability to provide fire suppression of specific high challenge fire hazards
,Extra large orifice sprinklers - answers -= or > 1 inch less pressure to achieve a given
discharge density
Extended coverage sprinkler - answers -400 max square feet discharge 20 foot by 20
foot spacing between sprinklers
Fire pump - answers -a 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 sprinkler - answers -operated 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
Hose valve - answers -valve to additional hose connection
Hydraulic placard - answers -sign 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 systems - answers -method of sizing auto sprinkler piping using
a prescribed amount of water to be distributed over a specific area.
Impairment coordinator - answers -in charge of safety during out of service systems
Intermediate level sprinkler - answers -sprinkler equipped with integral shields to protect
the operating elemtn form discharge from sprinklers installed at higher elevations
Large orifice sprinkler - answers -sprinkler head with orifice size equal or greater than
3/4 and less than 1 inch
Listed device - answers -a 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 valve - answers -a pressure reducing valve installed to
regulate pressures in an entire fire protection system and/or standpipe system zone.
Main drain - answers -the primary drain connection located on the system riser and also
utilized as a flow test connection.
Microbiologically influenced corrosion (mic) - answers -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 - answers -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 sprinkler - answers -a sprinkler designed to be installed in such a way that the
water stream is directed downward against the deflector.
Pintle screws - answers -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 systems - answers -a method of sizing piping based upon the number of
sprinkler heads and the occupancy of the protected area.
Preaction sprinkler system - answers -a 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 valve - answers -a 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 valve - answers -a valve designed for the purpose of reducing the
downstream water pressure under both flowing (residual) and nonflowing (static)
conditions.
Pressure relief valve - answers -a valve designed for the purpose of releasing excess
air or water pressure from the fire protection piping system.
Pressure tank - answers -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 head - answers -a sprinkler having a fusible link with a
response time index (rti) of 50 or less.
Recessed sprinkler - answers -a sprinkler in which all or part of the body, other than the
shank thread, is mounted above the ceiling.
Residential sprinkler - answers -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) - answers -a measurement of the thermal sensitivity of a
sprinkler head expressed in (meters-seconds) 1/2.
