2027 Update
standpipe system - correct-answer -an arrangement of piping, valves, hose
connections and allied equipment installed in a building or structure with the hose
connections located in such a manner that water can be discharged in streams or
spray patterns through attached hose and nozzles, for the purpose of
extinguishing a fire, thereby protecting a building or structure and its contents in
addition to protecting the occupants. this piping is is installed in a building or
structure that serves to transfer water from a water supply to hose connections at
one or more locations in a building or structure used for firefighting purposes.
combination standpipe and sprinkler system - correct-answer -a system where the
fire protection piping services 2 1/2 in. outlets for fire department use and outlets
for automatic sprinklers
Multi-zone standpipe - correct-answer -a standpipe system that is subdivided as
required by the construction codes, including the building code, into zones to limit
,2|Page
the maximum operating pressure in the system. each zone will have its own
individual automatic water supply
Static Pressure - correct-answer -the measurement of system pressure under non
flow conditions
strainer - correct-answer -a device capable of removing from the water all solids
of sufficient size that are obstructing water spray nozzles
supervisory signal - correct-answer -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 feature of related systems
Supervisory signal-initiating device - correct-answer -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.
Testing - correct-answer -a procedure used to determine the status of a system as
intended by conducting periodic physical checks on water based fire protection
systems such as water flow tests, fire pump tests, alarm tests, and trip tests of dry
, 3|Page
pipe or deluge valves. these tests follow the requirements for acceptance testing
at intervals specified in the appropriate chapter of NFPA #25, 2002 edition
Water Hammer - correct-answer -the surge in pressure when a high-velocity flow
of water is abruptly shut off. the pressure exerted by the flowing water against a
closed system can be seven or more times that of the static pressure.
water spray - correct-answer -water in a from having a predetermined pattern,
particle size, velocity, and density discharge from specially designed nozzles or
devices
water supply - correct-answer -a source of water that provides the flows [gal/min
(L/min)] and pressures [psi(bar)] required by the water based fire protection
system
water tank - correct-answer -a tank supply water for water based fire protection
systems
wet standpipe system - correct-answer -A standpipe system having piping
containing water at all times.
