957RPDA
Reduced Pressure Detector Assembly Backflow Preventers with Flood Sensor, Stainless Steel – Sizes 2 1/2 - 10 IN
Series 957RPDA reduced pressure detector assemblies feature a flood sensor using SentryPlus Alert® technology to detect continuous discharge from the relief valve. When paired with an add on connection kit, the sensor is activated to relay alerts for potential flooding events. Connection kit options include BMS, cellular communication, and the Sensor Control Monitor which enables integration with BAS via RS-485 Modbus or the Nexa® platform through Wi-Fi.
This series help 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. Check with local water authorities for installation requirements.
