,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

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.
, Pressure Control Valve - Correct Answer 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.
Pressure-Reducing Valve - Correct Answer A valve designed for the purpose of reducing
the downstream water pressure under both flowing (residual) and nonflowing (static)
conditions.
Pressure Relief Valve - Correct Answer A valve designed for the purpose of releasing
excess air or water pressure from the Fire Protection Piping System.
Pressure Tank - Correct Answer 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 - Correct Answer A sprinkler having a fusible link with a
response time index (RTI) of 50 or less.
Recessed Sprinkler - Correct Answer A sprinkler in which all or part of the body, other than
the shank thread, is mounted above the ceiling.
Residential Sprinkler - Correct Answer A type of fast response sprinkler that has been
specifically tested to enhance survivability in the room of fire origin and listed for use in
dwelling units.
Response Time Index (RTI) - Correct Answer A measurement of the thermal sensitivity of
a sprinkler head expressed in (meters-seconds) 1/2.
Supervisory signal - Correct Answer A signal indicating the need for action or the use of
such device in connection with the supervision of fire alarm systems or the maintenance
features of related systems.
Small orifice sprinklers - Correct Answer A sprinkler head with and orifice size smaller than
1⁄2"
Solder Link Sprinkler - Correct Answer A sprinkler operated by the melting of a metal link,
they vary in size and configuration for quick response and standard response sprinklers.
The smaller the size of the link, the faster the sprinkler operates.
