Pressure Supervisory Switch

Description

The switch is used to monitor the pressure within the Clean Agent cylinder. If a cylinder leaks occurs, and it’s pressure drops to below 291±10 psig, the switch contacts will be activated, providing a signal to the Release Control Panel to indicate loss of pressure and/ or leakages. The Pressure Supervisory Switch is wired into a supervised circuit to give a trouble signal upon activation.
