Tamper Switch for Butterfly Valves and Post Indicator Valves features a flexible design that installs easily post-indicator valves, butterfly valves, recessed wall post valves, and pressure-reducing valves in water-based systems. Safe Signal's PIBV2 Supervisory Switch prevents valve tampering and unwanted valve closure by activating a nearby alarm or fire alarm control panel when the valve reaches 1/5 of its travel distance or two full turns. Mounts with a 1/2 in. (6.35 mm) NPT nipple.
Featuring weatherproof die-cast metal housing and approvals from UL, ULC, FM, MEA, and California Office of the State Fire Marshal, this rugged Tamper Switch for Butterfly Valves and Post Indicator Valves is designed for indoor or outdoor use. Safe Signal's PIBV2 Supervisory Switch is suitable for service in accordance with NFPA 13, NFPA 13D, NFPA 13R, and NFPA 72 when properly installed.
Each Tamper Switch for Butterfly Valves and Post Indicator Valves includes tamper-resistant screws, a security wrench, and a bi-directional actuator that allows the unit to be installed in either rising or falling flag installations. Safe Signal's PIBV2 Supervisory Switch simultaneously activates connected signaling and monitoring devices with 100 percent synchronization.
This Tamper Switch for Butterfly Valves and Post Indicator Valves installs easily using a single-side conduit entrance that eliminates the need for right-angle fittings as well as an adjustable-length actuator.Additional Specifications
