Excess Pressure Pump Supervisory Switch
The Potter PS100 Pressure Actuated Switches are designed primarily to detect a decrease from normal system pressure in automatic fire sprinkler systems. A typical application is for an alarm initiating device that is used on a wet system with excess pressure. The PS100-2 has two SPDT switches factory set to operate on a pressure drop at 90 PSI (6,2 BAR).
