Potter Electric Signal PS10-1

The Potter PS10-1 is a pressure-actuated switch that detects waterflow conditions in wet-pipe fire sprinkler systems with alarm check valves, as well as dry-pipe, pre-action, and deluge configurations. Beyond flow detection, it doubles as a low-pressure supervisory switch across an adjustable 4 to 15 PSI (0.27–1.03 BAR) range, so a single device can cover both jobs on the same system. It's built into a die-cast, NEMA 4/IP55-rated enclosure with a non-corrosive 1/2" NPT nylon pressure connection, making it suitable for indoor or outdoor use with the right conduit fittings.
