FFA.WOSY OS&Y Valve Supervisory Switch – Fire Protection Valve Monitoring Device
The FFA.WOSY OS&Y Valve Supervisory Switch is a reliable monitoring device designed to detect and report the open or closed position of Outside Screw & Yoke (OS&Y) gate valves used in fire protection systems. It helps ensure that critical isolation valves remain in the correct operating position by providing a supervisory signal when unauthorized valve movement occurs.
Designed for direct installation on compatible OS&Y valves, the FFA.WOSY supervisory switch uses a mechanical position-sensing mechanism to monitor valve stem movement. Its durable, corrosion-resistant housing supports dependable operation in commercial and industrial fire protection environments.
The switch can be integrated with compatible fire alarm and building monitoring systems to provide valve position supervision and improve system readiness.
