This \u003cstrong\u003edual SPDT contact switch\u003c\/strong\u003e ensures precise signaling if the valve is moved from the fully open position, facilitating seamless integration with fire alarm control panels or local notification devices. The NEMA 3R-rated enclosure features a rugged, weather-resistant design with a synchronized activation mechanism, preventing false alarms by requiring the valve stem to travel a specific distance before triggering the \u003cstrong\u003esupervisory signal\u003c\/strong\u003e. Designed for \u003cstrong\u003etamper resistance\u003c\/strong\u003e, the \u003cstrong\u003eOSY2 valve switch\u003c\/strong\u003e includes a cover screw with a specialized security wrench. Its adjustable mounting bracket accommodates a wide variety of valve sizes, ranging from 1 inch to 12 inches, making it a versatile field-replaceable component. The \u003cstrong\u003edry contact switch\u003c\/strong\u003e configuration allows for simultaneous monitoring of the valve state and local status indication without cross-interference, meeting NFPA 72 requirements for \u003cstrong\u003egate valve supervision\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual SPDT Contacts:\u003c\/strong\u003e Provides two sets of Form C contacts for versatile wiring of \u003cstrong\u003esupervisory circuits\u003c\/strong\u003e and auxiliary equipment.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eField-Adjustable Trip Point:\u003c\/strong\u003e Allows for precise calibration to the valve yoke, ensuring the \u003cstrong\u003eOS\u0026amp;Y monitor\u003c\/strong\u003e activates exactly when needed.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNEMA 3R Protection:\u003c\/strong\u003e Built to withstand harsh environments, protecting internal \u003cstrong\u003eterminal connections\u003c\/strong\u003e from moisture and dust.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Mounting:\u003c\/strong\u003e The slotted bracket design simplifies installation on various \u003cstrong\u003efire sprinkler gate valve\u003c\/strong\u003e configurations.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTamper-Proof Design:\u003c\/strong\u003e Features a specialized housing to prevent unauthorized access or adjustment after commissioning.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\n\u003cp\u003e\u003cstrong\u003eHow do you wire an OSY2 switch for a fire alarm panel?\u003c\/strong\u003e\u003cbr\u003e\nThe OSY2 utilizes \u003cstrong\u003eSPDT switch contacts\u003c\/strong\u003e.
