Overview

2GIG outdoor wireless contact — weather-rated magnetic contact for gates, sheds, and exterior openings (including encrypted DW30 / ePlus outdoor SKUs).

On 2GIG systems, wireless devices are supervised zones on the panel — tamper, low battery, and missing signals appear as trouble conditions that may block arming depending on panel programming.

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

  • Sensor SKU — standard 345 MHz vs eSeries encrypted vs ePlus 900 MHz.
  • Panel online — resolve panel AC/cell trouble before blaming sensor.
  • Range — repeaters (RPTR1) or transceivers (XCVR2) for distant zones.
  • Battery type — use listed cell; replace all batteries in multi-cell devices.
  • Tamper — cover fully closed before declaring hardware fault.

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 outdoor contact install guide 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.

How do I replace a sensor?

Delete old zone in installer programming, enroll replacement using Learn mode, and test walk test at final location.

Will Alarm.com show this device?

When the panel has active interactive service, enrolled zones appear in the Alarm.com app with status matching the panel.

Where is official documentation?

How do I test after installation?

Use panel walk test, zone status, and (if monitored) central station test per dealer procedure.

Can I mix 345 MHz and ePlus sensors?

ePlus 900 MHz sensors require XCVR2 transceiver hardware — they do not enroll on the standard 345 MHz receiver alone.
