CERTIFICATE OF FITNESS S-12 DEFINITIONS
EXAM QUESTIONS AND ANSWERS |
GRADED A
Intermediate Level Sprinkler/Rack Storage Sprinkler - ANS -A sprinkler equipped with integral
shields to protect the operating element from discharge from sprinklers installed at higher
elevations.
Large orifice sprinkler - ANS -A sprinkler head with and orifice size equal to or greater than ¾"
and less than 1".
Listed Device - ANS -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 - ANS -A pressure reducing valve installed to regulate pressures
in an entire fire protection system and/or standpipe system zone.
Main Drain - ANS -The primary drain connection located on the system riser and also utilized as
a flow test connection.
Microbiologically Influenced Corrosion (MIC) - ANS -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.
Out of service system - ANS -A fire protection system that is not fully functional; or whose
operation is impaired or is otherwise not in good working order.
, Old-Style/Conventional Sprinkler - ANS -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 - ANS -A sprinkler designed to be installed in such a way that the water
stream is directed downward against the deflector.
Pintle Screws - ANS -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 - ANS -A method of sizing piping based upon the number of sprinkler
heads and the occupancy of the protected area.
Preaction Sprinkler System - ANS -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.
Personal Supervision - ANS -Supervision by the holder of a FDNY Certificate of Fitness who is
required to personally present on the premises, or other proximate location acceptable to the
department, while performing the duties for which the certificate is required.
Pressure Control Valve - ANS -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 - ANS -A valve designed for the purpose of reducing the downstream
water pressure under both flowing (residual) and nonflowing (static) conditions.
