Connections

  • This assembly features grooved inlet and outlet connections for straightforward installation and integral pipeline adjustment.
  • The grooved couplings facilitate easy installation and proper pipe alignment.

Flood Sensor Connectivity

  • To activate the integrated flood sensor, an add-on sensor connection kit is required.
  • Without the connection kit, the flood sensor remains a passive component and will not communicate with external devices.
  • Available connection kit options include BMS, cellular communication, or the Sensor Control Monitor, which integrates with Building Automation Systems (BAS) via RS-485 Modbus or the Nexa® platform via Wi-Fi.
