FULL REVIEW GRADED A+
◉ system control valve. Answer: valve controlling flow to water-
based fire protection systems.
◉ fire command center. Answer: 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.. Answer: 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. Answer: on closed section valves serving affected areas: area
affected, brief description, occupancy classification, c of f number,
estimated time until operational
◉ Green tag. Answer: no impairment found in entire system- main
control valve
,◉ red tag. Answer: 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. Answer: partially out of service- on all fire department
connections
◉ water storage tank. Answer: Collects cooled water
◉ OS & Y valve. Answer: indicating type of control valve used for fire
sprinkler system
◉ deluge valve. Answer: 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. Answer: 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. Answer: fast response
sprinkler that is listed for its capability to provide fire suppression
of specific high challenge fire hazards
◉ extra large orifice sprinklers. Answer: = or > 1 inch less pressure
to achieve a given discharge density
◉ extended coverage sprinkler. Answer: 400 max square feet
discharge 20 foot by 20 foot spacing between sprinklers
◉ fire pump. Answer: 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. Answer: 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. Answer: valve to additional hose connection
◉ hydraulic placard. Answer: 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. Answer: method of sizing auto
sprinkler piping using a prescribed amount of water to be
distributed over a specific area.
◉ impairment coordinator. Answer: in charge of safety during out of
service systems
◉ intermediate level sprinkler. Answer: sprinkler equipped with
integral shields to protect the operating elemtn form discharge from
sprinklers installed at higher elevations
◉ large orifice sprinkler. Answer: sprinkler head with orifice size
equal or greater than 3/4 and less than 1 inch
◉ listed device. Answer: 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. Answer: A pressure reducing
valve installed to regulate pressures in an entire fire protection
system and/or standpipe system zone.
