Description

The First Alert Hard-Wired Smoke and Carbon Monoxide Detector with Battery Backup is an essential dual-protection safety device designed to keep your home and family safe from two of the most dangerous household threats: smoke from fast-flaming fires and carbon monoxide exposure. Combining ionization smoke sensing technology with an advanced electrochemical CO sensor, this detector ensures quick and reliable detection of emergencies, giving you critical time to respond.

The hard-wired design means the detector is powered by your home’s electrical system, ensuring continuous operation, while the built-in battery backup keeps the alarm functioning even during a power outage—making it ideal for critical areas such as hallways, bedrooms, basements, and living spaces.

Designed with user convenience in mind, it features a loud 85-decibel alarm that alerts you immediately to danger, and a single test/silence button that simplifies maintenance and false alarm management. It also includes an end-of-life alert, notifying you when the unit needs replacement rather than leaving you unprotected. Installation is straightforward with the included mounting hardware and universal wiring compatibility.

Whether you’re upgrading home safety or complying with building codes that require interconnected alarms, this unit can be linked with other compatible First Alert alarms to create a home-wide alert system—when one alarm sounds, all connected units alert.
