FDNY Sprinkler Standpipe System
Questions and answers
Automatic Standpipe System - ✅✅A standpipe system that is attached to a water supply capable of
supplying the system demand at all times and that requires no action other than opening a hose valve to
provide water at hose connections.
Churning - ✅✅A condition in a centrifugal in which the impeller is rotating, but no water is being
discharged.
Combination Standpipe and Sprinkler System - ✅✅A system where the water piping service both 2
1/2in (65) outlet for fire Department use and oulet for automatic sprinkler
Concealed Sprinkler - ✅✅A recessed sprinkler with a cover plate
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. Suitable for HAZARDOUS
OCCUPANCIES. INTENDED USE IS MANUAL AND AUTO
Deludge Sprinkler System - ✅✅A 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 of a DETECTION
SYSTEM installed in the same area as the sprinklers
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. AUTO/NON_AUTO
Dry Standpipe - ✅✅A standpipe system designed to have piping contain water only when the system
is being utilized (NO AUTOMATIC WATER SUPPLY)
Fire Department Connection - ✅✅A connection, normally on the exterior of the building. (FORMERLY
KNOW AS SIAMESE CONNECTION)
Fire Hose - ✅✅A flexible conduit constructed of one or more reinforcements (JACKETS),
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.
Bulb Sprinkler - ✅✅A sprinkler operated by heat breaking a glass bulb filled with a non-freezing liquid
with diamiter that vary from 3mm for quick response sprinklers to 5mm for standard response
sprinklers.
, Hose Connection - ✅✅a combination of equipment provided for connection of a hose to the
standpipe system that includes a hose valve with a threaded outlet.
Hose Station - ✅✅a combination of a hose rack, hose nozzle, hose, and hose connection.
Impairment Coordinator - ✅✅Person responsible for ensuring the proper safety precautions are
taken when the fire protection system is placed out of service (designated by the owner)
In Service - ✅✅The Status of hose stored in a hose house, on a rack or reel, or on a fire apparatus that
is available and ready for immediate use at an incident.
Personal Supervision - ✅✅Supervision by the holder of a department certificate who is required to be
personally present on the premises, or other proximate location acceptable to the department, while
the duties for which the certificate is required is being performed.
Pressure Restricting Device - ✅✅A valve or device designed for the purpose of reducing of reducing
the downstream water pressure under both flowing (residual) and non-flowing (static) conditions
Pressure Reducing Valve - ✅✅A valve or device designed for the purpose of reducing of reducing the
downstream water pressure under flowing (residual) conditions only.
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.
Standpipe System - ✅✅An arrangement of piping, valves, and hose connections installed in a
structure to deliver water for fire hoses.
Combination Standpipe and Sprinkler System - ✅✅A system where the fire protection piping services
both 21⁄2 in. (65 mm) outlets for fire department use and outlets for automatic sprinklers.
Static Pressure - ✅✅The measurement of sytem pressure inder NON FLOW CONDITIONS.
Standpipe/ Multi-Zone - ✅✅A standpipe system that is vertically subdivided as required by the
construction codes, including the Building Code, into zones to limit the maximum operating pressure in
the system. Each zone will have its own individual automatic water supply.
Supervisory Signal - ✅✅A signal indicating the need for action in connection with the supervision of
guard tours, fire extinguishing systems or equipment, fire alarm systems or the maintenance features of
related systems.
Supervisory Signal-Initiating Device - ✅✅An initiating device, such as a valve supervisory switch,
water level indicator, or low-air pressure switch on a dry-pipe or pre-action sprinkler system, that
triggers a supervisory signal.
