supplemental water into the sprinkler system, standpipe, or other system furnishing water for fire
extinguishment to supplement existing water supplies.
system control valve - ANS valve controlling flow to water-based fire protection systems.
U
fire command center - ANS 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
LA
controlled.
Fire pump, automatic standpipe. - ANS 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.
C
tags - ANS on closed section valves serving affected areas: area affected, brief description,
occupancy classification, c of f number, estimated time until operational
Green tag - ANS no impairment found in entire system- main control valve
O
red tag - ANS place on main control valve if FULLY out of service... put sprinkler company
name, date of removal from service and anticipated time to operational
D
blue disk - ANS partially out of service- on all fire department connections
water storage tank - ANS Collects cooled water
OS & Y valve - ANS indicating type of control valve used for fire sprinkler system
deluge valve - ANS 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 - ANS 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 - ANS fast response sprinkler that is listed for its
capability to provide fire suppression of specific high challenge fire hazards
extra large orifice sprinklers - ANS = or > 1 inch less pressure to achieve a given discharge
density
A
extended coverage sprinkler - ANS 400 max square feet discharge 20 foot by 20 foot
spacing between sprinklers
R
fire pump - ANS 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
U
Glass bulb sprinkler - ANS 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
LA
hose valve - ANS valve to additional hose connection
hydraulic placard - ANS sign attached to a hydraulically calculated sprinkler system
indicating the design density, required gallons per minute and pressure for the system to
operate properly
C
hydraulically calculated systems - ANS method of sizing auto sprinkler piping using a
prescribed amount of water to be distributed over a specific area.
O
impairment coordinator - ANS in charge of safety during out of service systems
intermediate level sprinkler - ANS sprinkler equipped with integral shields to protect the
D
operating elemtn form discharge from sprinklers installed at higher elevations
large orifice sprinkler - ANS sprinkler head with orifice size equal or greater than 3/4 and
less than 1 inch
listed device - ANS 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 - ANS A pressure reducing valve installed to regulate
pressures in an entire fire protection system and/or standpipe system zone.
Main Drain - ANS The primary drain connection located on the system riser and also
utilized as a flow test connection.
Microbiologically Influenced Corrosion (MIC) - ANS 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 - ANS A sprinkler that directs 40% to 60% of the water
A
initially in a downward direction and is designed to be installed with the deflector in either the
upright or pendent position.
R
Pendent Sprinkler - ANS A sprinkler designed to be installed in such a way that the water
stream is directed downward against the deflector.
Pintle Screws - ANS A visual indicating device required for sprinklers manufactured prior to
U
1999 identifying small orifice sprinklers and large orifice sprinklers where orifice size is different
than the nominal thread size of the sprinkler head.
LA
Pipe Schedule Systems - ANS A method of sizing piping based upon the number of
sprinkler heads and the occupancy of the protected area.
Preaction Sprinkler System - ANS 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.
C
Pressure Control Valve - ANS 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.
O
Pressure-Reducing Valve - ANS A valve designed for the purpose of reducing the
downstream water pressure under both flowing (residual) and nonflowing (static) conditions.
D
Pressure Relief Valve - ANS A valve designed for the purpose of releasing excess air or
water pressure from the Fire Protection Piping System.
Pressure Tank - ANS 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 - ANS A sprinkler having a fusible link with a response
time index (RTI) of 50 or less.
