Connections

  • The NPT inlet and outlet connections are designed to be threaded onto corresponding male NPT pipes.

Flood Sensor Activation

The integrated SentryPlus Alert® flood sensor is a passive component until an add-on connection kit (sold separately) is installed. This kit is required to activate the sensor's communication capabilities, allowing it to relay alerts for potential flooding events via BMS, cellular communication, or integration with a BAS system through RS-485 Modbus or the Nexa® platform through Wi-Fi.
