affected, brief description, occupancy classification, c of f number, estimated time until
operational
Green tag - Correct Answer ✔✔ no impairment found in entire system- main control
valve
red tag - Correct Answer ✔✔ place on main control valve if FULLY out of service... put
sprinkler company name, date of removal from service and anticipated time to
operational

connections
water storage tank - Correct Answer ✔✔ Collects cooled water
,OS & Y valve - Correct Answer ✔✔ indicating type of control valve used for fire sprinkler
system
deluge valve - Correct Answer ✔✔ 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 - Correct Answer ✔✔ 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.
Early suppresion fast response sprinklers - Correct Answer ✔✔ fast response sprinkler
that is listed for its capability to provide fire suppression of specific high challenge fire
hazards
extra large orifice sprinklers - Correct Answer ✔✔ = or > 1 inch less pressure to achieve
a given discharge density
extended coverage sprinkler - Correct Answer ✔✔ 400 max square feet discharge 20
foot by 20 foot spacing between sprinklers
fire pump - Correct Answer ✔✔ a provider of liquid flow and pressure dedicated to fire
protection. A fire pump is a part of a fire sprinklers system water supply and can be
powered by electric, diesel or steam. connected to public water source or tank. provides
higher pressure to sprinkler system
Glass bulb sprinkler - Correct Answer ✔✔ operated by heat breaking a glass bulb filled
with a non freezing liquid with diameters that vary form 3 mm for quick response to 5
mm for standard response
hose valve - Correct Answer ✔✔ valve to additional hose connection
hydraulic placard - Correct Answer ✔✔ 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 - Correct Answer ✔✔ method of sizing auto sprinkler
piping using a prescribed amount of water to be distributed over a specific area.
impairment coordinator - Correct Answer ✔✔ in charge of safety during out of service
systems
,intermediate level sprinkler - Correct Answer ✔✔ sprinkler equipped with integral
shields to protect the operating elemtn form discharge from sprinklers installed at higher
elevations
large orifice sprinkler - Correct Answer ✔✔ sprinkler head with orifice size equal or
greater than 3/4 and less than 1 inch
listed device - Correct 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.
Master Pressure Reducing Valve - Correct Answer ✔✔ A pressure reducing valve
installed to regulate pressures in an entire fire protection system and/or standpipe
system zone.
Main Drain - Correct Answer ✔✔ The primary drain connection located on the system
riser and also utilized as a flow test connection.
Microbiologically Influenced Corrosion (MIC) - Correct 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.
Old-Style/Conventional Sprinkler - Correct Answer ✔✔ 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 - Correct Answer ✔✔ A sprinkler designed to be installed in such a
way that the water stream is directed downward against the deflector.
Pintle Screws - Correct 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 - Correct Answer ✔✔ A method of sizing piping based upon the
number of sprinkler heads and the occupancy of the protected area.
Preaction Sprinkler System - Correct 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 - Correct 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 - Correct Answer ✔✔ A valve designed for the purpose of
reducing the downstream water pressure under both flowing (residual) and nonflowing
(static) conditions.
Pressure Relief Valve - Correct Answer ✔✔ A valve designed for the purpose of
releasing excess air or water pressure from the Fire Protection Piping System.
Pressure Tank - Correct 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 - Correct Answer ✔✔ A sprinkler having a fusible link
with a response time index (RTI) of 50 or less.
Recessed Sprinkler - Correct Answer ✔✔ A sprinkler in which all or part of the body,
other than the shank thread, is mounted above the ceiling.
Residential Sprinkler - Correct 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) - Correct Answer ✔✔ A measurement of the thermal
sensitivity of a sprinkler head expressed in (meters-seconds) 1/2.
Supervisory signal - Correct 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 - Correct Answer ✔✔ A sprinkler head with and orifice size
smaller than 1⁄2"
Solder Link Sprinkler - Correct 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.
