Installation

This 6 inch Reduced Pressure Detector Assembly is designed for horizontal N pattern installation and connects to pipelines using groove couplings for easy alignment.

Flood Sensor Connectivity

The integrated flood sensor requires an add-on connection kit to activate its alert capabilities. Without this kit, the sensor operates as a passive component and will not communicate with external devices. Connection kit options include:

  • Building Management System (BMS) integration
  • Cellular communication
  • Sensor Control Monitor for integration with BAS via RS-485 Modbus or Nexa® platform through Wi-Fi
