Supervisory Switches

The nerve centers of a fire sprinkler system are the switches and valves that control the entire system. System Sensor offers a variety of choices for supervising system control valves. Regardless of valve type (outside screw valve monitoring and yoke, post indicator, butterfly, or non-rising stem gate valve), our OSY2, PIBV2, and PSP1 models provide you with the peace of mind that comes from knowing that your system’s control valves are being monitored.
