Connections

  • This backflow preventer assembly features union connections for straightforward installation into existing piping systems.
  • The flood sensor, which detects excessive water discharge, can be activated using an add-on connection kit (sold separately).
  • Connection kit options include BMS, cellular communication, or the Sensor Control Monitor for integration with BAS (via RS-485 Modbus) or the Nexa® platform (via Wi-Fi).

Drainage

Installation of a drain line is recommended, and an air gap is necessary when installing a drain line for the relief valve discharge. Proper drainage is required regardless of the flood sensor.
