Help Me Connect

This backflow preventer's flood sensor requires an add-on sensor connection kit for activation to detect excessive water discharges. Without this kit, the flood sensor acts as a passive component and will not communicate with other devices. Connection kit options include Building Management System (BMS) integration, cellular communication, or the Sensor Control Monitor.

The Sensor Control Monitor enables integration with a Building Automation System (BAS) via RS-485 Modbus or with the Nexa® platform through Wi-Fi.
