The LTE-X Series Communicator connects to a security system's control panel and sends alarms and messages to AlarmNet for transfer to a central monitoring station. It can be mounted directly on the control panel or remotely. The communicator reports fire, burg, and status messages, and uses 2-way ECP communication. It supports remote control of the alarm system and allows uploading/downloading of control panel data. For new installations, an AlarmNet 360 account is required. Programming can be done via the AlarmNet 360 website or the 7720P Programming Tool. The device uses LTE network for communication and attempts SMS if a data connection cannot be established. Supervision and fault detection features are included to monitor communication status. Registration with AlarmNet is necessary for the communicator to activate and send reports. Diagnostic commands and status displays are available for troubleshooting and monitoring.
