Sprinkler system Questions and Correct
Answers
Sprinkler system Ans: — An arrangement of pipes, valves,
sprinkler heads and alarms intended for fire fighting operations.
Has its own separate water supply.
Fire department connection Ans: — This is the external connection
point where firefighters can connect their hoses and pump water
into the sprinkler system.
GREEN caps
Sprinkler riser Ans: — Vertical pipe that delivers water to sprinkler
heads.
Includes various devices like pressure gauges, drains & alarms.
Sprinkler head Ans: — Activates when temperture exceeds it's
designated heat
tolerence.
Fire pump Ans: — Maintains sprinkler water pressure
Waterflow switch Ans: — Waterflow's monitor the movement of
water in a sprinkler system. Upon water flowing inside a sprinkler
system, a water flow signal will activate at the fire alarm panel.
OS&Y Ans: — Outside stem and yoke. An indicating valve that
regulates the flow of water.
Tamper switch Ans: — This device is attached to the main control
valve.
Movement from the valves normal position, sends a supervisory
alarm to the fire panel.
Pressure gauge Ans: — A device that measures and displays
pressure readings.

Inspectors test valve Ans: — Utilised to create the same pressure
drop as a fused sprinkler head. Tests a systems water flow device
activation.
Fire command panel Ans: — Monitors all building fire alarm
devices
Combination system Ans: — A system that combines standpipe
and sprinkler systems into one system that shares a water supply.
YELLOW caps
Auto. Wet sprinkler system Ans: — Always loaded with water, 40
degrees or higher, monitored by fire alarm system
Auto. Dry sprinkler system Ans: — Designed for cold
environments, below 40 degrees, pressurised air in piping, activate
because of pressure drops
Dry pipe valve Ans: — Contains clapper that prevents water from
entering piping system
Accelerator/Exhauster Ans: — Quick opening device. Activate with
2 psi drop in pressure causing water to enter a dry system faster
Pre-action Ans: — Sprinkler system with no water or pressurised
air in piping.
Pre-action valve prevents water from entering piping until fire
detectors (smoke detector, pull-station) are activated.
Water will remain at sprinkler head until heat fuses the head.
Pre-action prevents accidental water release from damaged
sprinklers.
Dry pipe/Pre-action combination Ans: — Piping is loaded with
pressurised air. Heat detecting devises (smoke detector, pull
station) activate and open water valve allowing water into system.
Deluge system Ans: — Equipped with open sprinkler heads.
Intended for hazardous areas that require rapid wet down (several
sprinkler heads fuse simultaneously)
