S12 SPRINKLER EVALUATION EXAM 2025 QUESTIONS
ANSD SOLUTIONS RATED A+
✔✔Control Valve - ✔✔A valve controlling flow to water-based fire protection systems.
Control valves do not include hose valves, inspector's test valves, drain valves, trim
valves for dry pipe, pre-action and deluge valves, check valves, or relief valves.
✔✔OS&Y Valve - ✔✔indicating type of control valve used for fire sprinkler system
✔✔Curb valve - ✔✔a non indicating gate valve equipped with a cast iron extension box
flushed with a sidewalk with an operating nut of 1 1/4 inch, this valve is operated using a
special curb key wrench. This valve controls municipal water supply serving the
standpipe system.
✔✔Corrosion-resistant sprinkler - ✔✔A sprinkler fabricated with corrosion resistant
materials, or special coatings to be used in an atmosphere that would corrode standard
sprinklers.
✔✔Deficiency - ✔✔A condition in which the application of the component is not within
its designed limits or specifications.
✔✔Critical deficiency - ✔✔A deficiency that, if not corrected can have an effect on the
performance of the fire protection system
✔✔Non critical deficiency - ✔✔A deficiency that does not have an effect on the
performance of the fire protection system, but correction is needed for proper
inspection,testing, and maintenance of the systems.
✔✔Deluge Valve - ✔✔water supply control valve intended to be operated by actuation
of an automatic detection system that is installed in the same area as the discharge
devices. INTENDED USE IS MANUAL AND AUTO
✔✔Deluge Sprinkler System - ✔✔employing open sprinklers that are attached to a
piping system that is connected to a water supply through a valve that is opened by the
operation of a detection system installed in the same areas as the sprinklers. WHEN IT
OPENS, water flows into the piping system and discharges from all sprinklers attached.
✔✔Dry Pipe Sprinkler System - ✔✔A sprinkler system employing automatic sprinklers
that are attached to a piping system containing air or nitrogen under pressure. The
release of the air or nitrogen,(as from the opening of a sprinkler) results in the water
pressure opening a valve known as a dry pipe valve, resulting in the flow of water into
the piping system and out of the fused sprinklers heads.
, ✔✔Dry Sprinkler - ✔✔A sprinkler secured in an extension nipple that has a seal at the
inlet to prevent water from entering the nipple until the sprinkler operates. May be
configured with an upright, pendent or sidewall sprinkler.
✔✔Discharge Device - ✔✔A device designed to discharge water or foam-water solution
in a predetermined, fixed, or adjustable pattern. Examples include, but are not limited to,
sprinklers, spray nozzles, and hose nozzles.
✔✔early suppression fast response sprinkler - ✔✔A type of fast response sprinkler that
is listed for its capability to provide fire suppression of specific high challenge fire
hazards.
✔✔extra large orifice sprinklers - ✔✔A sprinkler head with an orifice size equal to or
greater than 1 inch. this sprinkler is used for protection of high piled storage in
warehouses and less pressure is required to achieve a given discharge density
✔✔Extended coverage sprinklers - ✔✔A type of spray sprinkler with a maximum area of
coverage of 400 square feet (20 foot by 20 foot spacing between sprinklers) for light
hazard occupancies to a maximum of 144 square feet (12 foot by 12 foot spacing
between sprinklers) for extra hazard occupancies.
✔✔Fire alarm system - ✔✔Any system, including any interconnected fire alarm sub-
system, of components and circuits arranged to monitor and annunciate the status of
fire alarm or supervisory signal-initiating devices.
✔✔Fire Department Connection - ✔✔A connection , normally on the exterior of the
building, through which the fire department can pump supplemental water into the
sprinkler system, standpipe, or other system furnishing water for fire extinguishment to
supplement existing water supplies.
(Formerly know as Siamese connection.)
✔✔Fire extinguishing system - ✔✔An approved system of devices and equipment which
detects a fire and discharges an approved fire extinguishing agent onto or in the area of
a fire. Such term includes automatic systems and, where such systems are authorized
by this code or the Building Code, manually activated systems.
✔✔fire hydrant - ✔✔A valve connection on a water supply system having one or more
outlets and that is used to supply hose and fire department pumps with water.
✔✔Fire Protection System - ✔✔Approved devices, equipment and systems or
combinations of systems used to detect a fire, activate an alarm, extinguish or control a
fire, control or manage smoke and products of a fire or any combination thereof,
including fire extinguishing systems, fire alarm systems, sprinkler systems and
standpipe systems.
