First Alert 10-Year Back-Up Hard-Wired Smoke & CO Alarm with Ionization Sensor

First Alert 10-Year Back-Up Hard-Wired Smoke and CO Alarm with Ionization Sensor

Meet a thoughtful balance of constant protection and user-friendly installation. The First Alert 10-Year Back-Up Hard-Wired Smoke and Carbon Monoxide Alarm combines hard-wired power with a long lasting 10-year battery backup to keep your home protected even during outages. The design emphasizes a crisp, reliable alarm that can wake you with a steady chirp and a bright indicator when needed, without overwhelming you during routine activities.

With Precision Detection technology, this unit adheres to updated industry standards to reduce nuisance alarms from cooking vapors and steam, while still delivering early warning in the event of a real home fire emergency. The ionization smoke sensing and CO detection are tuned to respond quickly to real threats, helping you react with calm, practical plans rather than panic.

How Precision Detection and Interconnect Work

During normal operation, the device runs on hard-wired power. If the lights go out, the built-in 10-year battery maintains operation, so you do not lose essential alerts. When one alarm detects smoke or CO, interconnected alarms will alert all compatible devices, providing a coordinated warning across the home.
