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

Your dry-pipe or preaction fire sprinkler system can be infected! That’s right – microbes can be lurking inside your sprinkler pipes and causing damage. Microbiologically influenced corrosion (MIC) occurs when the right combination of moisture and microbial organisms produces rapid corrosion of steel piping from the inside out. MIC is not the only cause of steel pipe corrosion, but it is important to know about and mitigate this problem BEFORE it causes pitting, pinholes, and thinning of pipe walls. Take steps to prevent both rust and MIC by using NITROGEN-PAC™.
