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.

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
- Mount and power panel; apply firmware updates per dealer bulletin.
- Install cell module and run communication test / Alarm.com activation.
- Enroll wireless sensors via installer Learn mode; label zones.
- Include Z-Wave devices after excluding from any prior hub.
- Install transceiver/repeater hardware before distant ePlus or fringe sensors.
- Run walk test, user code training, and central station test if monitored.
GC3 placement
- Mount panel central to wireless sensor layout — not buried in basement corner if sensors are upstairs.
- Route LTE antenna per module guide — attic ANT5XL when internal RSSI is weak.
- Connect AC power before enrolling many sensors; verify battery charges.
- Complete installer programming (zone definitions, dialer, cell module) before user handoff.
