Flood Sensor Connectivity

The integrated flood sensor with SentryPlus Alert technology can be enhanced with an add-on connection kit. This allows the sensor to relay alerts for potential flooding events via various communication methods. Options include direct integration with Building Automation Systems (BAS) via RS-485 Modbus or through the Nexa platform by Wi-Fi connectivity using the Sensor Control Monitor. Cellular communication and other BMS options are also available.
