Potter PS120-2 Pressure Switch with Two Sets SPDT Contacts

Ensure constant, reliable pressure monitoring for your fire protection and water-flow systems with the Potter Electric Signal, LLC PS120-2 supervisory pressure switch. Designed for wet pipe systems, pressure tanks, air supplies and water supplies, the PS120-2 actively detects both increases and decreases from normal system pressure—helping protect equipment and reduce false alarms that can interrupt operations. The PS120-2 comes factory-set to 120 PSI and features a 10 PSI actuation differential (operates low at 110 PSI and high at 130 PSI), giving consistent, repeatable supervisory signals. Two independent SPDT contacts let you route separate supervisory and alarm circuits or parallel monitoring for security and building surveillance systems. Installers benefit from tool-free adjustments, two 1/2" conduit entrances and isolated wiring chambers that speed wiring and improve safety. The non-corrosive pressure connection and non-conductive enclosure extend service life in humid or corrosive environments. Compact (3.78" W x 3.2" D x 4.22" H) and rugged, the PS120-2 integrates easily into fire alarm, security monitoring and water-flow control setups. Add the PS120-2 to your fire protection monitoring or contact us to specify it for your next project.
