Overview

2GIG LTE or 3G cell radio module — adds cellular alarm reporting and Alarm.com (or dealer ADC / SecureNet / Telus) interactive services to a compatible GC2, GC3, or Edge panel.

Without reliable cellular reporting, remote arm/disarm and central station signals stop when phone lines or broadband fail. Match the exact module SKU to your panel model and dealer platform before truck roll.

What This Device Does Well

Provides reliable supervised status at the panel and Alarm.com when installed, enrolled, and range-tested correctly.

Before You Service or Replace One

  • ICCID and carrier — verify active SIM on correct network.
  • Module-to-panel pairing — GC2 vs GC3 vs Edge slot compatibility.
  • Antenna path — internal vs ANT5XL external routing.
  • Dealer platform — Alarm.com activation tied to specific module SKU.

Official Sources

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

Installation Notes

Follow Cell module install guide; Alarm.com activation checklist 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.

Cell module install

  • Match module to panel model and dealer platform (Alarm.com vs ADC vs SecureNet vs Telus).
  • Install antenna before powering module for first time when manual requires it.
  • Run communication test and document ICCID for dealer activation.
