Guaranteed Success
fire department connection - ✔✔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 - ✔✔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.
tags - ✔✔on closed section valves serving affected areas: area affected, brief
description, occupancy classification, c of f number, estimated time until
operational

,Green tag - ✔✔no impairment found in entire system- main control valve
red tag - ✔✔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 - ✔✔partially out of service- on all fire department connections
water storage tank - ✔✔Collects cooled water
OS & Y valve - ✔✔indicating type of control valve used for fire sprinkler system
deluge valve - ✔✔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 - ✔✔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 - ✔✔fast 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 pump - ✔✔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 - ✔✔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 - ✔✔valve to additional hose connection
hydraulic placard - ✔✔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 - ✔✔method of sizing auto sprinkler piping
using a prescribed amount of water to be distributed over a specific area.
impairment coordinator - ✔✔in charge of safety during out of service systems

, intermediate level sprinkler - ✔✔sprinkler 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 device - ✔✔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 - ✔✔A pressure reducing valve installed to
regulate pressures in an entire fire protection system and/or standpipe system
zone.
Main Drain - ✔✔The 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.
