Antifreeze Sprinkler System - ANSWERSA wet pipe sprinkler system employing automatic sprinklers that
are attached to a piping system that contains an antifreeze solution and is connected to a water supply.
The antifreeze solution is discharged, followed by water, immediately upon operation of sprinklers
opened by heat from a fire.
Combination Standpipe and Sprinkler System - ANSWERSA system where the water piping services both
2½ in. (65 mm) outlets for fire department use and outlets for automatic sprinklers.
Concealed Sprinkler - ANSWERSA recessed sprinkler with a cover plate
Control Valve - ANSWERSA valve controlling flow to water-based fire protection systems. Control valves
do not include hose valves, inspector's test valves, drain valves, trim valves for dry pipe, preaction and
deluge valves, check valves, or relief valves.
OS & Y valve (Outside Stem and Yoke valve) is an indicating type of control valve used for fire sprinkler
system.
Corrosion-Resistant Sprinkler - ANSWERSA sprinkler fabricated with corrosion resistant materials, or
special coatings to be used in an atmosphere that would corrode standard sprinklers.
Deficiency - ANSWERSA condition in which the application of the component or system(s) is not within
its designed limits or specifications.
Dry Pipe Sprinkler System - ANSWERSA sprinkler system employing automatic sprinklers that are
attached to a piping system containing air or nitrogen under pressure. The release of the air or nitrogen,
(as from the opening of a sprinkler) results in the water pressure opening a valve known as a dry pipe
valve, resulting in the flow of water into the piping system and out of the fused sprinklers heads.
, Dry Sprinkler - ANSWERSA sprinkler secured in an extension nipple that has a seal at the inlet to prevent
water from entering the nipple until the sprinkler operates. May be configured with an upright, pendent
or sidewall sprinkler.
Discharge Device - ANSWERSA device designed to discharge water or foam-water solution in a
predetermined, fixed, or adjustable pattern. Examples include, but are not limited to, sprinklers, spray
nozzles, and hose nozzles.
Early Suppression Fast Response Sprinkler (ESFR) - ANSWERSA type of fast response sprinkler that is
listed for its capability to provide fire suppression of specific high challenge fire hazards.
Fire Department Connection - ANSWERSA connection , normally on the exterior of the building, through
which the fire department can pump supplemental water into the sprinkler system, standpipe, or other
system furnishing water for fire extinguishment to supplement existing water supplies. (Formerly know
as Siamese connection.)
Glass Bulb Sprinkler - ANSWERSA sprinkler operated by heat breaking a glass bulb filled with a non
freezing liquid with diameters that vary from 3mm for quick response sprinklers to 5mm for standard
response sprinklers.
Hose Valve - ANSWERSThe valve to an individual hose connection.
Extra Large Orifice Sprinklers (ELO) - ANSWERSA sprinkler head with and orifice size equal to or greater
than 1". Pparticularly for protection of high piled storage in warehouses and less pressure is required to
achieve a given discharge density.
Extended Coverage Sprinklers - ANSWERSA type of spray sprinkler with a maximum area of coverage of
400 square feet (20 foot by 20 foot spacing between sprinklers) for light hazard occupancies to a
maximum of 144 square feet (12 foot by 12 foot spacing between sprinklers) for extra hazard
occupancies.
Hydraulic Placard - ANSWERSA sign attached to a hydraulically calculated sprinkler system indicating the
design density, required gallons per minute and pressure for the system to operate properly.
