S-12 CITYWIDE SPRINKLER SYSTEMS EVALUATION EXAM
2025/2026 QUESTIONS WITH ANSWERS RATED A+
✔✔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.
, ✔✔Old-Style/Conventional Sprinkler - ✔✔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 - ✔✔A sprinkler designed to be installed in such a way that the
water stream is directed downward against the deflector.
✔✔Pintle Screws - ✔✔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 - ✔✔A method of sizing piping based upon the number of
sprinkler heads and the occupancy of the protected area.
✔✔Preaction Sprinkler System - ✔✔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 - ✔✔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 - ✔✔A valve designed for the purpose of reducing the
downstream water pressure under both flowing (residual) and nonflowing (static)
conditions.
✔✔Pressure Relief Valve - ✔✔A valve designed for the purpose of releasing excess air
or water pressure from the Fire Protection Piping System.
✔✔Pressure Tank - ✔✔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 - ✔✔A sprinkler having a fusible link with a
response time index (RTI) of 50 or less.
✔✔Recessed Sprinkler - ✔✔A sprinkler in which all or part of the body, other than the
shank thread, is mounted above the ceiling.
✔✔Residential Sprinkler - ✔✔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.
