TOSY OS&Y Valve Supervisory Switch – Fire Valve Position Monitoring Device
The TOSY OS&Y Valve Supervisory Switch is a reliable monitoring device designed to supervise the open and closed position of Outside Screw & Yoke (OS&Y) gate valves used in fire protection systems. It provides a supervisory signal to the fire alarm control panel when the valve position changes from its normal operating condition, helping maintain system readiness and safety.
Designed for integration with fire sprinkler and fire protection networks, the TOSY supervisory switch features a durable, corrosion-resistant enclosure and a mechanical valve position sensing mechanism for dependable operation in commercial, industrial, and utility applications.
The switch mounts directly onto compatible OS&Y valves and uses electrical contacts to transmit valve status information to monitoring systems. Its compact design supports easy installation, reliable operation, and effective supervision of critical fire protection isolation valves.
