Protege DIN Rail
Cellular Modem


The Protege DIN Rail Cellular Modem is a cellular communication device that provides a convenient wireless connection for a Protege controller. With no physical network required this is an ideal solution for remote sites and installations where network infrastructure may be unavailable, or difficult and expensive to install. Supports both Protege GX and Protege WX controllers.

  • Wireless IP alarm transmission for convenient, cost-effective monitored outbound reporting
  • Secure encrypted communication when reporting via the ArmorIP reporting service
  • Category M-1 cellular network capability with fallback to 2G GSM
  • 4G, Dual Mode LTE-M/NB-IoT cellular technology


IP alarm transmission capability allows communication of alarms from a controller to a monitoring station via cellular network transmission, delivering convenient, cost-effective monitored outbound reporting.

On supported networks the modem can receive programming updates from the Protege GX system for Protege GX controllers.

The cellular modem can upload events from the Protege GX controller to the Protege GX events database.

On supported networks the modem can receive manual control commands from the Protege GX system for Protege GX controllers, providing live control over doors, areas, outputs, inputs and more.

With no physical network required the Protege DIN Rail Cellular Modem provides a connection solution without barriers. Cellular network communication means more accessible and more cost-effective reporting to monitoring station automation software than traditional copper line solutions, and enables access in locations where physical connections are not possible.

When using ICT's ArmorIP reporting service, provides secure AES encryption on data transmissions.

The cellular modem includes continuous connection detection and automatic fail reset. If there is an error with the cellular connection the controller will automatically reset the modem to attempt to resolve the connection.

The Protege controller web interface displays the cellular network connection status and details, including signal strength, the Mobile Network Operator the cellular modem is currently connected to, and its network registration status.

The modem can provide a secondary reporting path as a backup to existing reporting connections.

With validated cellular network providers across the globe, the Protege DIN Rail Cellular Modem can perform virtually anywhere.
