S-12 CITYWIDE SPRINKLER SYSTEMS 2023
VERIFIED PRACTICE TEST BANK 2026
TESTED QUESTIONS WITH ANSWERS
GRADED A+
⩥ Master Pressure Reducing Valve. Answer: A pressure reducing valve
installed to regulate pressures in an entire fire protection system and/or
standpipe system zone.
⩥ Main Drain. Answer: The primary drain connection located on the
system riser and also utilized as a flow test connection.
⩥ Microbiologically Influenced Corrosion (MIC). 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. 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. Answer: A sprinkler designed to be installed in
such a way that the water stream is directed downward against the
deflector.
⩥ Pintle Screws. 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. Answer: A method of sizing piping based
upon the number of sprinkler heads and the occupancy of the protected
area.
⩥ Preaction Sprinkler System. 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. 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. Answer: A valve designed for the purpose
of reducing the downstream water pressure under both flowing (residual)
and nonflowing (static) conditions.
