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.

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.

Official Sources

Use official 2GIG PDFs and install guides for exact wiring, enrollment, and firmware — specifications vary by SKU and region.

Installation Notes

Follow 2GIG GC2/GC2e user guide and install/programming documentation and the official resource links in this product folder for mounting, wiring, and enrollment.

Pre-install checklist

  • Confirm panel model (GC2/GC3/Edge) and encryption requirements.
  • Verify dealer cell account and module SKU before cell install.
  • Document installer code and existing zone map for takeover jobs.
  • Plan antenna routing (ANT5XL) when panel location has poor cell RSSI.
  • Have listed batteries and tools for sensor mounts before enrollment.

Typical install sequence

  1. Mount and power panel; apply firmware updates per dealer bulletin.
  2. Install cell module and run communication test / Alarm.com activation.
  3. Enroll wireless sensors via installer Learn mode; label zones.
  4. Include Z-Wave devices after excluding from any prior hub.
  5. Install transceiver/repeater hardware before distant ePlus or fringe sensors.
  6. Run walk test, user code training, and central station test if monitored.
