2GIG-SMKT-900 Smoke Heat Freeze Detector

The 2GIG-SMKT-900 is an E+ extended-range, two-way encrypted life-safety sensor for the 2GIG EDGE platform. It uses an optical (photoelectric) smoke chamber, adds fixed heat + rate-of-rise and freeze monitoring, and supports One Go/All Go so all E+ smokes sound together. Rated up to ~1.2 miles (open air) on 900 MHz, with a built-in ≥85 dB sounder.

Why Choose This with Smart Shield Systems


  • Edge-ready setup: We verify your 2GIG EDGE firmware (v1.3+), enroll the detector, and test alarm/restore, tamper, and supervision events.

  • Whole-home alerting: We enable and verify One Go/All Go, so all installed E+ smokes will sound in unison during an alarm.

  • Best-practice placement: We follow manufacturer guidance for room coverage and perform sounder/communication tests.

  • Lifecycle tracking: We document batteries and set maintenance reminders for cleaning and periodic testing.


Key Features


  • Extended range: up to ~1.2 miles (open air) on the 900 MHz E+ platform.
