Dry Systems
Dry Systems are a mechanical type of fire protection
system that maintains air pressure in in the pipes of the
system. These systems are used when there is an issue with
the potential of the pipes freezing such as in a parking
garage. On Dry systems there is a dry valve in a heated area
that controls the system. This valve holds back the water
until the system loses enough air pressure where the valve
can no longer hold back the water pressure. The valve will
then trip sending water flowing through the pipes. The water
will fill the system and flow water through whichever
sprinkler head(s) have fused. These systems are to be tested
regularly by simulating an air loss on the system which will
then trip the dry valve.
A Dry system needs to be constantly maintained and all
low points in the system need to be drained regularly to
assure that there is no water in the pipes that could
freeze.
