Potter PS40-EX Series Supervisory Pressure Actuated Switches are designed primarily to detect an increase and/or decrease from normal system pressure in automatic fire sprinkler systems located in hazardous locations. Typical applications are: air/nitrogen supervision in dry pipe and pre-action systems, pressure tanks, air supplies, and water supplies. The PS40-EX has two switches. The Low switch is factory set to activate at approximately 30 psi (2,1 BAR) on a decrease in pressure. The High switch is factory set to activate at approximately 50 psi (3,5 BAR) on an increase in pressure. NFPA 72 requires a supervisory signal if the pressure increases or decreases by 10 psi from normal. The PS40 is factory set for a normal air pressure of 40 psi
