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.
Early suppresion fast response sprinklers

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
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
valve to additional hose connection
hydraulic placard
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
method of sizing auto sprinkler piping using a prescribed amount of water to be
distributed over a specific area.
impairment coordinator
in charge of safety during out of service systems
intermediate level sprinkler
sprinkler equipped with integral shields to protect the operating elemtn form discharge
from sprinklers installed at higher elevations
large orifice sprinkler
sprinkler head with orifice size equal or greater than 3/4 and less than 1 inch
listed device
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
A pressure reducing valve installed to regulate pressures in an entire fire protection
system and/or standpipe system zone.
Main Drain
The primary drain connection located on the system riser and also utilized as a flow test
connection.
Microbiologically Influenced Corrosion (MIC)
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
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
A sprinkler designed to be installed in such a way that the water stream is directed
downward against the deflector.
Pintle Screws
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
A method of sizing piping based upon the number of sprinkler heads and the occupancy
of the protected area.
Preaction Sprinkler System
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
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
A valve designed for the purpose of reducing the downstream water pressure under
both flowing (residual) and nonflowing (static) conditions.
Pressure Relief Valve
A valve designed for the purpose of releasing excess air or water pressure from the Fire
Protection Piping System.
Pressure Tank
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
A sprinkler having a fusible link with a response time index (RTI) of 50 or less.
Recessed Sprinkler
A sprinkler in which all or part of the body, other than the shank thread, is mounted
above the ceiling.
Residential Sprinkler
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)
A measurement of the thermal sensitivity of a sprinkler head expressed in (meters-
seconds) 1/2.
Supervisory signal
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
A sprinkler head with and orifice size smaller than 1⁄2"
Solder Link Sprinkler
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
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
A sprinkler having a fusible link with a response time index (RTI) of 80 or more.
