Carbon Monoxide Alarm

Keep your home safe from the “silent killer” with our encrypted carbon monoxide alarm. Using an electrochemical sensor and a built-in 85 dB Temporal-4 sounder, it alerts locally and sends secure signals to your panel. The eSeries (CO8e-345) version adds AES-128 encryption for tamper-resistant, authenticated wireless communication—ideal for modern 2GIG systems.

Why Choose This with Smart Shield Systems


  • Right model, right panel: we match CO8e-345 (encrypted) to GC2e/GC3e/EDGE, or CO8-345 (classic) to legacy 345-MHz panels—then enroll and test.

  • Code-aware placement: we mount near sleeping areas and fuel-burning appliances per best practices, then verify alarm reporting and monitoring.

  • Lifecycle tracking: we document the detector’s 10-year sensor/battery life and schedule reminders so you’re never unprotected.


Key Features


  • Enhanced security: AES-128 encrypted wireless (eSeries) helps prevent spoofing/replay.

  • Loud local alert: integrated 85 dB sounder with Temporal-4 CO pattern.

  • Long life design: 10-year sensor life and projected 10-year batteries (2× AAA).

  • Strong RF performance: up to ~350 ft open-air range; full supervision, tamper, and low-battery reporting.

Frequently Asked Questions


What makes this “enhanced security”?


The eSeries (CO8e-345) model uses AES-128 encryption so the panel can authenticate signals, reducing the risk of spoofing or interference.


How long does it last?


The sell sheet lists ~10 years for both sensor and battery life; the unit signals end-of-life when it’s time to replace.


How loud is the alarm?


It uses an 85 dB Temporal-4 tone designed specifically for CO events, and it also reports to your panel for app alerts and monitoring.


Will it reach my panel?


Open-air spec is about 350 ft; we test signal quality on site and position the detector for reliable supervision and alarm signaling.


Which panels does it support?


CO8e-345 pairs with GC2e, GC3e, and EDGE; the CO8-345 pairs with legacy 2GIG 345-MHz systems. We’ll choose and enroll the right version for your setup.
