1.2 SYSTEM DESCRIPTIONS
A. Wet-Pipe Sprinkler System: Automatic sprinklers are attached to piping containing
water and that is connected to water supply. Water discharges immediately from
sprinklers when they are opened. Sprinklers open when heat melts fusible link or
destroys frangible device. Hose connections are included if indicated.
B. Dry-Pipe Sprinkler System: Automatic sprinklers are attached to piping containing air
that is connected to a dry valve and water supply. Water discharges from sprinklers
once a sprinkler solders and air discharges from the system. Sprinklers open when
heat melts fusible link or destroys frangible device.
