Applications of the transmitter


This contact/status change transmitter is specifically designed for smart building, security and industrial applications.

It meets all types of ON/OFF status change monitoring needs thanks to its two TOR inputs (binary output signal).

The main uses of contact transmitter monitoring are :

  • Presence, break-in and access control :
    –> Monitoring of door openings and closures in office environments, or security gates in industrial areas (warehouses, machine access, etc.).
  • Monitoring of machines and systems :
    –> Detection of system failures, monitoring of machine operating timeslevel alerts, etc.

The robustness of our transmitter – IP 65 enclosure – and its high environmental tolerance (-20°C / +55°C) allow it to withstand any type of environment.

Real-time alerts from the Enless Wireless contact/status change transmitter via its two dry contact interfaces will allow you to implement quick actions in response to the received messages.

> You can remotely change your transmitter configuration from the Sigfox Backend without manual intervention or the need to restart the transmitter to take its new configuration.
