Overview
The 2GIG GC3 (and GC3e encrypted variant) is a touchscreen all-in-one wireless security panel with built-in Z-Wave home automation, 345 MHz wireless sensor support, optional LTE cell modules, and Alarm.com interactive services when paired with a compatible communicator.
The panel is the brain of the 2GIG system: it supervises wireless zones, drives local sirens, manages Z-Wave automation, and reports to Alarm.com (or your dealer monitoring platform) when a compatible cell module is installed and activated. Installers program zones, user codes, and dialer options in the installer menu; end users arm/disarm from the touchscreen, keyfobs, or Alarm.com app.
