Question 5

Définition Wet Pipe

Answer 5

A wet pipe sprinkler
system has a series of piping systems connected to regularly distributed sprinkler heads, fed by a main riser

Question 6

Définition Dry Pipe

Answer 6

Dry pipe sprinkler systems are installed in areas where distribution pipes are subject to freezing temperatures, such
as unheated buildings and parking garages. Unlike wet pipe sprinkler systems that contain water, dry pipe sprinkler systems contain compressed air. The compressed air is
supplied by an electric air compressor, nitrogen bottles, or other source.

Question 7

Définition Deluge Systems

Answer 7

Deluge sprinkler systems work similarly to the wet pipe sprinkler system, except the system incorporates open sprinkler heads or nozzles that do not operate individually. The
water is held back by an electric solenoid valve that is connected to a compatible releasing panel. An initiating device,
such as a smoke detector, sends a signal to the monitoring panel which energizes the release circuit which opens the solenoid valve.

Question 8

Définition Pre-action Systems

Answer 8

Pre-action sprinkler systems are installed in water sensitive
environments such as computer rooms and refrigerated warehouses. These areas require systems that will operate only in an actual fire condition to save the building and its components from severe fire damage.
The pre-action system is similar to a dry pipe system, except
that air pressure may or may not be used. It is also similar
to the deluge system, except that the valve is electronically
held closed and standard “closed” sprinkler heads are used. This design eliminates operational delays and water damage. The valve will only open if an independent detection
system installed in the same area as the sprinkler system is activated, verifying a fire condition.
