Pressure Supervisory Switch (N/C) – UL Listed

The Pressure Supervisory Switch part CP50138-1 is used to monitor the pressure within the Clean Agent cylinder. If a cylinder leak occurs, and its pressure drops to below 291±10 psig, the switch contacts will be activated, providing a signal to the Release Control Panel to indicate lost of pressure and/or leakages. The pressure supervisory switch is wired into a supervised circuit to give a trouble signal upon activation.
