SPRINKLERS SEGMENT 5, S-12 CITYWIDE
SPRINKLER SYSTEMS QUESTIONS AND
ANSWERS
fire department connection - CORRECT ANSWER- 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 - CORRECT ANSWER- valve controlling flow to water-based fire
protection systems.
fire command center - CORRECT 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. - CORRECT 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 - CORRECT ANSWER- on closed section valves serving affected areas: area
affected, brief description, occupancy classification, c of f number, estimated time until
operational
Green tag - CORRECT ANSWER- no impairment found in entire system- main control
valve
red tag - CORRECT 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 - CORRECT ANSWER- partially out of service- on all fire department
connections
water storage tank - CORRECT ANSWER- Collects cooled water
OS & Y valve - CORRECT ANSWER- indicating type of control valve used for fire
sprinkler system
deluge valve - CORRECT 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 - CORRECT 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 - CORRECT ANSWER- fast response
sprinkler that is listed for its capability to provide fire suppression of specific high
challenge fire hazards
extra large orifice sprinklers - CORRECT ANSWER- = or > 1 inch less pressure to
achieve a given discharge density
extended coverage sprinkler - CORRECT ANSWER- 400 max square feet discharge 20
foot by 20 foot spacing between sprinklers
fire pump - CORRECT 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 - CORRECT 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 - CORRECT ANSWER- valve to additional hose connection
hydraulic placard - CORRECT 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 - CORRECT ANSWER- method of sizing auto sprinkler
piping using a prescribed amount of water to be distributed over a specific area.
impairment coordinator - CORRECT ANSWER- in charge of safety during out of service
systems
intermediate level sprinkler - CORRECT ANSWER- sprinkler equipped with integral
shields to protect the operating elemtn form discharge from sprinklers installed at higher
elevations
large orifice sprinkler - CORRECT ANSWER- sprinkler head with orifice size equal or
greater than 3/4 and less than 1 inch
listed device - CORRECT 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 - CORRECT ANSWER- A pressure reducing valve
installed to regulate pressures in an entire fire protection system and/or standpipe
system zone.
Main Drain - CORRECT ANSWER- The primary drain connection located on the system
riser and also utilized as a flow test connection.
Microbiologically Influenced Corrosion (MIC) - CORRECT ANSWER- 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 - CORRECT ANSWER- 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 - CORRECT ANSWER- A sprinkler designed to be installed in such a
way that the water stream is directed downward against the deflector.
Pintle Screws - CORRECT ANSWER- 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 - CORRECT ANSWER- A method of sizing piping based upon
the number of sprinkler heads and the occupancy of the protected area.
Preaction Sprinkler System - CORRECT ANSWER- 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.
