How Does Dual Path Monitoring Work on a 2GIG GC3?

When Dual Path communication is enabled on the 2GIG GC3, all signals meant for the monitoring station are sent via both paths at once. Alarm.com acknowledges and forwards whichever signal is received first, and ignores the other. This ensures that signals always use the fastest route.

The GC3 system already includes a built in WIFI communicator, and must be on firmware version 3.1.0 or higher to utilize it. A separate cellular module is needed for cellular communication, which is required for monitoring and use with Alarm.com remote services. There are three available cellular communicators for the system. You should select the communicator that provides you with the strongest signal strength for your area. There are two Verizon communicators and one AT&T communicator.

In order to use cellular communication with your GC3 system, you will need to activate the cellular module with your alarm monitoring company. After installing the module into your GC3 panel, contact your alarm monitoring company and tell them that you would like to activate your account. Your monitoring company will need to know the Serial Number for the communicator before this process can be completed. Once installed, you can find the serial number by pressing the 2GIG logo in the upper right of the home screen, entering the Installer Code (default is 1561) then pressing "Radio Status". The Serial Number will be displayed on this screen.

Dual path monitoring is not required, and the GC3 system can be fully supported using cellular only, but can not use WIFI only. The serial number of the cellular communicator is required in order to create an Alarm.com account, and the system will always be identified by this serial number.
