Overview
The 2GIG GC2 (and GC2e encrypted variant) is a compact touchscreen wireless panel supervising 345 MHz sensors, Z-Wave devices, and optional LTE communicators for Alarm.com or dealer monitoring platforms.
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.
At a Glance
| Specification | Details |
|---|---|
| Role | Compact touchscreen alarm panel |
| Wireless sensors | 345 MHz 2GIG sensors; GC2e supports eSeries encrypted |
| Automation | Z-Wave devices |
| Cellular | GC2 LTE CAT1 modules — verify ADC vs Alarm.com vs SecureNet SKU |
| Programming | Installer code on panel |
| Form factor | Smaller footprint vs GC3 — plan sensor count and range |
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
| Panel / keypad display | Meaning | First checks |
|---|---|---|
| COMM FAIL / Cell failure | Cellular path down | Antenna, SIM, carrier, module SKU vs account |
| 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 |
