elevations
large orifice sprinkler - Answer -✔✔sprinkler head with orifice size equal or greater than
3/4 and less than 1 inch
listed device - 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.

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.

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.
Pressure Relief Valve - Answer -✔✔A valve designed for the purpose of releasing
excess air or water pressure from the Fire Protection Piping System.
Pressure Tank - 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 - Answer -✔✔A sprinkler having a fusible link with a
response time index (RTI) of 50 or less.
Recessed Sprinkler - Answer -✔✔A sprinkler in which all or part of the body, other than
the shank thread, is mounted above the ceiling.
Residential Sprinkler - 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) - Answer -✔✔A measurement of the thermal sensitivity of a
sprinkler head expressed in (meters-seconds) 1/2.
Supervisory signal - 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 - Answer -✔✔A sprinkler head with and orifice size smaller than
1⁄2"
Solder Link Sprinkler - 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.

supervisory switch,that triggers a supervisory signal.
Testing - Answer -✔✔A procedure used to determine the status of a system as intended
by conducting periodic physical checks on water based fire protection systems such as
waterflow tests, fire pump tests, alarm tests, and trip tests of dry pipe, deluge, or
preaction valves. These tests follow up on the original acceptance test at intervals
specified in the appropriate chapter of NFPA #25, 2002 edition.
Upright Sprinkler - Answer -✔✔A sprinkler designed to be installed in such a way that
the water spray is directed upwards against the deflector.
