form of dry pipe system that uses larger pipes and
therefore delivers a significantly larger volume of water.
wet pipe system
dry pipe system
deluge system
preaction system
deluge system
a combination dry pipe/wet pipe system. The system exists as a dry pipe until the initial stages of a fire (smoke, heat, and so on) are detected, and
then the pipes are filled with water. The water is released only after the sprinkler head activation triggers are melted by sufficient heat.
wet pipe system
dry pipe system
deluge system
preaction system
preaction system
is always full of water. Water discharges immediately when suppression is triggered. wet pipe system dry pipe system deluge system preaction system
wet pipe system
contains compressed air. Once suppression is triggered, the air escapes, opening a water valve that in turn causes the pipes to fill and discharge
water into the environment.
