PS40-2
Overview
Designed to deliver dependable supervisory pressure monitoring for fire sprinkler and building protection systems, the Potter PS40-2 is a pressure switch built for reliable, real-world performance. As a Potter Electric Signal, LLC pressure switch in the PS40 series, the PS40-2 comes factory-set for 40 PSI nominal pressure and features two sets of SPDT contacts to detect both high and low pressure deviations (±10 PSI trip settings). That means faster, more accurate detection for dry-pipe, pre-action, air/nitrogen supervision, and water supply applications—reducing downtime and improving safety monitoring.
Installers and facility managers benefit from a robust zinc construction, a non-conductive enclosure, two 1/2" conduit entrances, and separate isolated wiring chambers that speed installation and reduce service calls. The independent, tool-free adjustment on two-switch models gives technicians field flexibility while supporting integration into fire alarm, security, and building monitoring systems. A VdS version is also available for projects requiring additional approvals.
For reliable sprinkler supervision and improved security and monitoring integration, specify the Potter PS40-2 supervisory pressure switch—order or consult our sales team for application guidance.
