PREACTION SPRINKLER

SYSTEM

With the Model G-2000, G-3000, or G-4000 Valve: When the detector operates, the solenoid valve

opens (Figure 10d). Prime water is drained from the prime chamber, causing the G series valve to

open, filling the sprinkler piping with water. Water from the intermediate chamber of the G series valve

pressurizes the sensing end of the PORV, causing the PORV to open, which continually vents

prime water pressure (Figure 10d).
