CITYWIDE SPRINKLER SYSTEMS
PRACTICE EXAM Questions and
Answers Latest Update 2025 TOP
RATED A+
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.
Spray Sprinkler - ANSWER✔✔-A type of sprinkler listed for its capability to
provide fire control for a wide range of fire hazards. The most commonly
used sprinkler since 1953.
Standard Response Sprinkler Head - ANSWER✔✔-A sprinkler having a
fusible link with a response time index (RTI) of 80 or more.
Supervisory signal-initiating device - ANSWER✔✔-An initiating device, such
as a valve 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.
Water Spray Fixed System - ANSWER✔✔-A special fixed pipe system
connected to a reliable fire protection water supply and equipped with
water spray nozzles for specific water discharge and distribution over the
surface or area to be protected.
PREACTION SPRINKLER SYSTEMS - ANSWER✔✔-designed for situations
where there is danger of serious water damage. Water damage is usually
caused by damaged sprinklers or broken piping. Under normal conditions
there is no water in the piping. The air in the piping may or may not be is
under pressure. A preaction valve prevents the water from entering the

,system. The valve is automatically opened when a fire detection system
discovers that there is a fire or smoke condition. The preaction valve is
tripped by the fire detection system before any of the sprinkler heads open.
A supervisory device signals when the valve is opened. The preaction valve
can also be operated manually.
