Products Description

CA-FIRE Gate Valve Monitoring Switch
The GSS01 OS&Y Supervisory Switch is a fire-specific monitoring device exclusively designed for Outside Screw and Yoke (OS&Y) type gate valves. Primarily used in fire sprinkler and water supply pipeline systems, it provides real-time monitoring of gate valve open/close status, delivers precise electrical signals, and triggers abnormal alarms, eliminating the risk of fire pipeline valve failure at the source. It is a core component for fire engineering acceptance and safe system operation.
Core Functions
✅ Precise Monitoring: Real-time feedback of OS&Y gate valve full open/full close status with stable, delay-free signal output
✅ Signal Compatibility: Supports 10A 125/250VAC and 2.0A 24VDC electrical parameters, compatible with mainstream fire monitoring panels
✅ Abnormal Alarm: Instantly triggers alarm signals for accidental valve closure or malfunction, preventing "faulty operation" of fire systems
✅ Exclusive Adaptation: 100% matches OS&Y (Outside Screw and Yoke) type gate valves, installable without modification
✅ Compliance Certification: Certified to NSF 401, meeting safety and acceptance standards for fire protection systems
