Fundamentals of Sprinkler Systems Test Solution Manual 100% Pass
Purpose: - Answers Definition: A system of pipes and attached nozzles or sprinklers carrying water or
other extinguishing fluid to the various parts of a building. The system is usually made to operate
automatically in the presence of great heat.
Purpose: - Answers Early detection of fire and effective application of the available water supply is
fundamental to minimizing most fire losses. very reliable method of obtaining this detection and
application is a properly installed and maintained automatic sprinkler system.
Definition: - Answers A system of pipes and attached nozzles or sprinklers carrying water or other

fires are extinguished or held in check by sprinkler systems. - Answers 96% of all fires
Types: - Answers Wet Pipe: Dry Pipe: Pre-Action: Deluge System: Combined System: Looped System:
Junior System: Dorothy Mae Ordinance:
Wet Pipe: - Answers Most common type - Water is under pressure at all times. Individual sprinklers are
attached. Some have retarding devices that collects water during pressure surges to prevent false
alarms.
Dry Pipe: - Answers Found in locations subject to freezing. - Air under pressure replacing water (15-50
psi.) Air escapes as water is discharged.
Pre-Action: - Answers Used to prevent water damage. - Activated by heat and smoke detectors. Heads
have fusible links
Deluge System: - Answers Used to protect high hazard occupancies. Activation results from fire, heat,
smoke or manual devices. Heads are fully open and water flows through all heads at the same time.
Combined System: - Answers Found in buildings from 1974 to present. - Over 75 feet in height. Sprinkler
system and 2%" standpipe are on the same riser.
Looped System: - Answers 1983-1988 Has two points of connection to the sprinkler system. Water is fed
to a sprinkler head from two or more risers.
Junior System: - Answers Simple inexpensive systems for light hazard occupancies were 3 or 4 heads are
likely to operate. System is fed through domestic water supply via 1" brass or copper pipe. Utilizes an
electric water flow alarm. No FDC or drain valve. Uses %" to 3/8" sprinkler heads. This is 1/2 by the
pintle extending from defector. Discharges half as much water as a 1/4" head. Uses 20 heads or less and
located in buildings 3 stories or less.
