The UNITED Fire Systems CMA-1 is a device for monitoring the possible corrosion inside of a wet or dry sprinkler system piping. The assembly consists of a corrosion probe in a chamber, a pressure switch, an isolation valve, and a drain valve. The corrosion probe keeps pressure from reaching the pressure switch. When corrosion perforates the probe, pressure reaches the pressure switch, actuating a signal and providing early warning of possible corrosion inside the piping. The isolation valve allows replacement of the corrosion probe without depressurizing the entire system, and the drain valve safely vents pressure from the probe chamber.
Inlet Connection = 1/2” NPT female
Pressure Switch Setting Range = 4 to 8 PSIG
Switch Contact Ratings = 10 A @ 125 / 250 VAC and 2 A @ 30 VDC
Maximum Recommended Inlet Pressure = 300 PSIG
