The Potter RBVS Universal Ball Valve Switch is the only patented product designed to monitor the full open position on any new or previously installed ¼ turn ball valve in a sprinkler system.

The RBVS complies with NFPA 72, 2007 6.8.5.10.4 and building codes requiring the monitoring of ball valves installed in the alarm lines of dry pipe, pre-action, and wet systems with alarm valves.  The RBVS is US patented (#6,945,509), UL/cUL listed, as well as FM approved.  It comes manufactured with a 1/2” opening for conduit and screw terminals for easy wire connections, as well as a NEMA 4 gasketed enclosure with single screw cover design.  Versatile mounting hardware on the RBVS allows for easy installation on ball valves and back flow preventers from ½” - 2”.
