Smart Shield Systems

Wireless Door/Window Contact

An extended-range, encrypted contact made for larger homes and light commercial sites. The 2GIG-DW10E-900 (E+ series) communicates on the 900 MHz spectrum with two-way encryption, delivers up to ~1.2 miles rated range (open air), and includes a pre-installed spacer for clean alignment on tricky frames. It can also monitor an external NO/NC dry contact in addition to its internal reed.

Why Choose This with Smart Shield Systems


  • RF survey & placement: we test signal paths and place the sensor for the strongest 900 MHz link—critical on large properties.

  • Clean install on narrow trim: the included spacer and our alignment checks reduce nuisance openings/closings.

  • Smart programming: we enroll/labeled zones (internal reed and optional external NO/NC input) and verify supervision and tampers.

  • Lifecycle support: we document the CR2450 battery and set reminders; expected life is up to ~8 years.


Key Features


  • E+ Extended Range: up to ~1.2 miles (open air; materials affect range).

  • Two-way encrypted communication for enhanced security and reliability.

  • Included spacer and installer-friendly housing for accurate alignment.

  • External input support: accepts Normally Open or Normally Closed dry contacts.

  • Long battery life: up to ~8 years typical.

Compatibility Notes


  • Purpose-built for the 2GIG EDGE platform (FW 1.3+). If you’re on a GC2e/GC3e/EDGE system using 345 MHz eSeries sensors today, we’ll confirm whether E+ 900 MHz is appropriate for the zones you want extended.

  • Indoor use sensor; for exterior gates/doors, see the DW30E-900 Outdoor contact.


Popular Use Cases


  • Far-end doors or windows in large homes where standard RF is marginal

  • Add-on zones that need an auxiliary wired contact (e.g., a hidden plunger or screen contact)

  • Light commercial runs across long corridors or between suites


Frequently Asked Questions


How far will it reach in the real world?


The E+ spec lists up to ~1.2 miles (open air). Actual range depends on construction and layout—we place and test to ensure reliable supervision.


Can it monitor a second switch?


Yes. The DW10E-900 supports an external NO or NC dry contact input in addition to its internal reed. We’ll wire and enroll it appropriately.


What battery does it use and how long does it last?


A CR2450 coin cell, with up to ~8 years typical life per datasheet. Your panel/app will alert on low battery.


Which panel does it work with?


The datasheet calls out the 2GIG EDGE panel with firmware 1.3 or later. We’ll confirm your firmware and complete an RF survey during installation.


Is it encrypted?


Yes—two-way encrypted communication is part of the E+ line for added security.


Ready for Extended-Range Perimeter Protection?


Smart Shield Systems will specify, mount, and enroll your 2GIG-DW10E-900, verify 900 MHz coverage, and set up notifications—so even the farthest doors and windows report perfectly.
