Figure 7 - Fire Condition

B. Fire Condition:

When the detection system operates, the normally closed solenoid valve is powered open. At this point, the prime water is still held

in the prime chamber by the closed pneumatic actuator. When a sprinkler operates, air pressure is lost on the sensing end of the

pneumatic actuator, causing the pneumatic actuator to open. With both the pneumatic actuator and solenoid valve open, prime

water is drained from the prime chamber, causing the G-3000P Valve to open, filling the sprinkler piping with water. Water from

the intermediate chamber of the G-3000P Valve pressurizes the sensing end of the PORV, causing the PORV to open. The open

PORV prevents water pressure from building in the prime chamber should the solenoid or pneumatic actuator close.
