Potter PS25-2 PS25 Series Low/High Supervisory Pressure Switch for Low Differential Dry and Preaction Valves Nominal System Pressure 25 psi

Ensure continuous, code-compliant pressure supervision for dry pipe and pre-action systems with the Potter Electric Signal PS25-2 supervisory pressure switch. This pressure supervisory switch delivers reliable high/low monitoring to detect deviations from normal system pressure, helping prevent false alarms and enabling fast response in building security and fire monitoring applications. The PS25-2 features two independent switches—factory-set low at approximately 18 psi and high at approximately 28 psi around a nominal 25 psi system—so you get precise supervision out of the box. Installation is streamlined with two 1/2" conduit/cable entrances and separate isolated wiring chambers for clean integration with alarm and surveillance panels. Built with a non-conductive enclosure and non-corrosive pressure connection, the PS25-2 is engineered for durability in challenging environments. Ideal for fire sprinkler supervision, pressure tanks, and air/nitrogen supervision in pre-action/dry pipe systems, this Potter PS25 Series device supports your security, monitoring, and compliance needs. Specify the PS25-2 for your next fire protection project or contact us to integrate it into your building monitoring setup.
