The System Sensor OSY2 Outside Screw and Yoke (OSY-Y) Valve Supervisory Switch is a critical monitoring device designed for comprehensive fire protection systems in commercial and industrial environments. This precision-engineered sensor provides critical valve position monitoring for wet, dry, and pre-action sprinkler systems, ensuring continuous supervision of critical fire suppression infrastructure.
Engineered to meet the stringent requirements of NFPA 72 National Fire Alarm and Signaling Code, the OSY2 offers reliable mechanical and electrical detection of valve status. When installed on fire protection system valves, this supervisory switch immediately communicates any unauthorized or accidental valve position changes to the main fire alarm control panel, enabling rapid response and maintaining system integrity.
Professionals typically install the OSY2 on gate valves in commercial facilities including office complexes, healthcare facilities, educational institutions, manufacturing plants, and high-rise buildings where comprehensive fire protection monitoring is essential. Its robust design ensures consistent performance in diverse environmental conditions.
