Overview

Pressure Switch with Two Sets SPDT Contacts

The Potter PS40 Series Supervisory Pressure Actuated Switches are designed primarily to detect an increase and/or decrease from normal system pressure in automatic fire sprinkler systems. Typical applications are: air/nitrogen supervision in dry pipe and pre-action systems, pressure tanks, air supplies, and water supplies. The PS40-2 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.

Features:

Two switch model
Independent switch adjustment on two switch models, no tools needed
Two 1/2" conduit/cable entrances
Separate isolated wiring chambers
Non-corrosive pressure connection
Non-Conductive Enclosure
Vds version available
