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

,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.
