Fire-Lite OSY2

Description

System Sensor’s OSY2 and OSY2A supervisory switches monitor the open position of an Outside Screw and Yoke (OS&Y) type gate valve. Robust construction. The OSY2(A) consists of a rugged housing, intended for indoor and outdoor use. When installed with the actuator in the vertical position, the OSY2(A) is NEMA 3R rated per UL. Application flexibility. The OSY2(A) features a user-friendly mounting bracket and adjustable shaft to permit mounting to most OS&Y valves, ranging in size from 1″ to 12″ (2.54 to 30.48 cm). Its right-angle design and wide bracket span provides maximum clearance for valve components, accommodating troublesome valves. Removing OSY2(A)’s gate valve bracket allows the unit to monitor side-bracket-style pressure reducing valves. Simplified operation. Installation is made easier with the OSY2(A)’s single-side conduit entrance. By providing a direct conduit pathway to the electrical source, right angle fittings are not required. Installation is further simplified by the OSY2(A)’s adjustable-length actuator, which eliminates the need for cutting the shaft. Reliable performance. The OSY2(A) is equipped with tamper resistant cover screws to prevent unauthorized entry. Inside, two sets of SPDT (Form-C) synchronized switches are enclosed in a durable terminal block to assure reliable performance.
