System Sensor's line of pressure switches includes the EPS10 Series for use in wet, dry, deluge, and pre-action automatic sprinkler systems to indicate a discharge from a sprinkler. The EPS40 and EPS120 Series supervisory pressure switches are intended for dry pipe systems or pressure tanks and water supplies of automatic water control valves. These models offer a choice of initiating low or high/low pressure monitoring alarms, in a variety of pressure ranges. And should your system involve a potentially hazardous location, System Sensor offers a complete line of explosion-proof alarm and supervisory pressure switches.

The WFDN Series waterflow detectors provide a mechanical time delay that is adjusted via an adjustment wheel. This retard mechanism is field replaceable, as is the terminal block.
The WFDTN is a T-Tap waterflow detector for use with a 1" NPT connection.
System Sensor WFDNFS & WFDNFT waterflow detectors are designed for primary signaling in systems that use CPVC fittings
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.
The OSY2 is used to monitor the open position of an outside screw and yoke (OS&Y) type gate valve.
The PIBV2 monitors the open position of post indicator and butterfly control valves
The PSP1 plug-in switch is designed for applications where no other type of listed valve supervisory switch can be used.
