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.

What This Panel Does Well
Coordinates intrusion zones, automation, user codes, and central station reporting when cell and monitoring are configured.
Before You Service or Replace One
- Exact panel model — GC2 vs GC3 vs Edge — firmware and modules differ.
- Encryption — GC2e/GC3e/Edge vs standard sensors in the field.
- Cell module SKU — Alarm.com vs ADC vs SecureNet vs Telus.
- Installer code — required for zone changes; document before service.
- Alarm.com dealer — account status, plan, and remote programming access.

Error Codes
2GIG systems report faults on the panel and keypad status screens, zone list, and Alarm.com (when interactive service is active) — not as a single universal numeric code list across all models.
How to read status
- Open panel status or installer menu → zones / troubles.
- Note zone number, trouble type (open, tamper, low battery, missing, cell fail).
- Cross-check Alarm.com device list if the account is interactive.
- For cell issues, run installer communication test before replacing sensors.
Common trouble indicators

| Sensor fault / zone open | Zone not secure or missing | Battery, gap, tamper, re-learn sensor |
| AC loss | Mains power removed | Transformer, outlet, power supply SKU |
| Low battery (panel) | Backup battery weak | Charge time; replace panel battery if aged |
| Z-Wave fault | Automation device offline | Exclude/re-include; verify within mesh range |
| Encryption fault | eSeries mismatch | Panel encryption support; sensor must match eSeries |
