Potter PS120-1 Pressure switch with one set SPDT contacts

Ensure reliable detection of abnormal pressure in fire sprinkler and water supply systems with the Potter PS120-1 Pressure Switch from Potter Electric Signal. This supervisory pressure switch is designed to monitor increases or decreases from a 120 psi normal system pressure and trips at factory-set 10 psi offsets — providing fast, repeatable alerts that help prevent unnoticed failures or nuisance alarms. The PS120-1 includes one set of SPDT contacts for straightforward connection to fire alarm control panels, security monitoring platforms and building automation systems.

Installers benefit from two 1/2" conduit entrances, isolated wiring chambers and a non-conductive enclosure that simplify wiring and improve safety. The durable die-cast body and non-corrosive pressure fitting stand up to typical wet pipe, standpipe, pressure tank and regulator applications. Compact (3.8" W x 3.2" D x 4.2" H) and US-made, the PS120-1 supports code-compliant supervisory monitoring for fire protection and security systems.
