Stainless Steel Reduced Pressure Detector Assembly Backflow Preventers with Flood Sensor, 2 1/2 - 10 Inch Sizes - C500-FS

Series C500 reduced pressure detector assemblies feature a flood sensor with SentryPlus Alert® technology to detect excessive water discharges from the relief valve. Activated through an add-on connection kit, the sensor can trigger the alert system sending notification of flood detection to facility personnel. Connection kits are available for BMS and cellular communication.

This series helps stop the reverse flow of fire protection system substances being pumped or siphoned into the potable water supply. A meter incorporated to detect ground leaks and unauthorized illegal taps greatly reduces annual water expenses. It is 70% lighter than traditional designs and is ideal for health hazard cross-connections, such as on fire sprinkler systems. Check with local water authorities for installation requirements.

The TS-OSY model is equipped with a factory installed, durable, and robust supervisory switch (UL Certified, Safety Signaling, Control No. 3L38) for tamper detection. The alert sounds when attempts are made to remove the switch from the gate valve or to close the valve. Wiring of the supervisory switch to a fire alarm control panel is required.
