Series LF957RPDA Lead Free* 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 provide protection to the potable water system from contamination in accordance with national plumbing codes. Used in health hazard applications to protect against backsiphonage and backpressure and to monitor unauthorized use of water from the fire protection system.
