Happy to assist! The 2GIG GC3 alarm panel is compatible with our service. However, due to the impending 3G sunset, Alarm.com will no longer allow new accounts to be created using 3G. Going forward 4G LTE modules are required.
The 4G LTE module for the 2GIG GC3 can be purchased here.
In order to be compatible with the module, your panel would need to be at firmware version Requires 3.1.3 firmware or later. Firmware files and patch notes can be found here.
Alternatively, if you were interested in switching to the Qolsys IQ Panel 2+ you would want the version with the 345MHz radio installed, which is compatible with 2GIG and Honeywell wireless sensors.
While that version is not available directly through our storefront, we oiffer the Qolsys IQ Panel 2+ (2GIG & Honeywell 345MHz) here.
The Qolsys IQ PAnel 2+ w/ 345MHz radio also includes a PowerG radio for compatibility with DSC PowerG encrypted sensors. IT has built in wi-fi for dual path communication and a Z-Wave Plus radio for home automation control.
The Qolsys panel would not be compatible with any existing secondary panels for the GC3, such as the SP1 or SP2. It is also not compatible with any of the 2GIG brand Image Sensors.
