Product Description

The Fire Supervisory Switch for OS&Y Gate Valve (MXHQ) is a critical safety component used in fire protection systems. It is specifically designed to monitor the position of an OS&Y (Outside Screw & Yoke) gate valve, which controls the flow of water to sprinkler systems or fire hydrants. The purpose of the switch is to ensure that the valve remains in the fully open position so that water can reach the system during a fire emergency.

When the OS&Y valve is closed or tampered with, the MXHQ supervisory switch detects this change in position and sends a signal to the building's fire alarm control panel. This alert allows maintenance personnel or fire safety teams to respond quickly and restore the valve to the correct position, ensuring continuous fire protection readiness. The switch typically includes a normally closed contact, which opens if the valve stem is moved from its fully open position.

The MXHQ model is built with a durable and weatherproof housing, making it suitable for both indoor and outdoor installations. It is commonly rated for environmental protection (such as NEMA 3R or IP65), ensuring reliable performance in harsh conditions. The unit is also UL listed and FM approved, meeting international fire safety standards.

Designed for ease of installation, the MXHQ fire supervisory switch can be mounted directly onto the yoke of OS&Y valves and connected to fire alarm systems using standard wiring terminals. Its use is widespread in commercial, industrial, and institutional settings where fire sprinkler systems are installed, and compliance with NFPA 13 and other fire codes is mandatory.
