Series LF909 Small Lead Free* Reduced Pressure Zone 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 prevents the reverse flow of contaminated water caused by backsiphonage or backpressure from entering the potable water supply. Ideal for protection at health hazard cross-connections or for containment at the service line entrance. Its compact modular design facilitates maintenance and assembly access. Check with local water authorities for installation requirements.
