Sprinkler systems that allow large volumes of water to be released in a short period of time are called:

A.
Wet pipe

B.
Deluge

C.
Preaction

D.
Dry pipe

Explanation:
Deluge systems are much like dry pipe systems, however their sprinkler
heads are open to allow for more water to be released more quickly. Dry pipes do not
hold water in the pipes, but in a water storage area. When a fire detection
mechanism sounds an alarm the water is released into the pipe. Deluge systems should
not be used in data processing environments. Preaction systems should be used
instead, because they provide a delayed reaction.
