S12 SPRINKLER FINAL PAPER 2025 QUESTIONS ANSD
SOLUTIONS RATED A+
✔✔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 (ESFR) - ✔✔A type of fast response
sprinkler that is listed for its capability to provide fire suppression of a specific high
challenge fire hazards
✔✔Extra Large Orifice Sprinklers (ELO)* - ✔✔A sprinkler head with and orifice size
equal to or greater than 1". 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. (Formally known as Siamese connection.)
✔✔Fire Extinguishing System - ✔✔Approved devices, equipment and 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 connections 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
✔✔Fire Pump - ✔✔A pump that is a provider of liquid flow and pressure dedicated to
fire protection. A fire pump is a part of a fire sprinkler system's water supply and can be
, powered by electric, diesel or steam. The pump intake is either connected to the public
underground water supply piping or a static water source (eg. Tank, reservoir, lake.)
The pump provides water flow at higher pressure to the sprinkler system risers and
hose standpipes. A pump used only to fill a tank is not a fire pump. The following fire
pumps are required to be maintained in accordance with the NYC fire code: [See: Fire
Pump (NYC Accordance Fire Code)]
✔✔Fire Pump
(NYC Accordance Fire Code) - ✔✔Fire pump, automatic standpipe: a fire pump located
at or below street level that supplies the lower 300 feet of a standpipe system or a
combined standpipe and sprinkler system
Fire pump, foam: a fire pump used to boost water supply pressures in a fire protection
system where such system uses firefighting foam as an additive
Fire pump, limited service: a fire pump with a motor rating not exceeding 30 hp and
utilizing a limited service fire pump controller
Fire pump, special service: a fire pump that is located above street level and that
receives its water supply from a gravity tank or suction tank supplying water to fire
sprinkler system and/or fire department hose outlets
Fire pump, sprinkler booster pump: a fire pump that supplies sprinkler systems only
Fire pump, water mist system: a fire pump used to boost water supply pressures in a
fire protection system where such system utilizes water misting technology
✔✔Glass Bulb Sprinkler - ✔✔A sprinkler operated by heat breaking a glass bulb filled
with non-freezing liquid with diameters that vary from 3mm for quick response sprinklers
to 5mm for standard response sprinklers
✔✔Hose Valve - ✔✔The valve to an individual hose connection
✔✔Hydraulic Placard - ✔✔A sign attached to a hydraulically calculated sprinkler system
indicating the design density, required gallons per minute and pressure for the system
to operate properly
✔✔Hydraulically Calculated Systems - ✔✔A method of sizing automatic sprinkler piping
using a prescribed amount of water to be distributed over a specific area
✔✔Impairment - ✔✔A condition where a fire protection system or unit or portion thereof
is out of order, and the condition can result in the fire protection system or unit not
functioning in a fire event
