First Alert Hardwired Smoke and Carbon Monoxide Alarm with Battery Backup

First Alert’s hardwired 2-in-1 smoke and carbon monoxide alarm is designed to provide early warning, with Precision Detection technology and an interconnect feature for compatible alarms.

• Precision Detection sensing — reduces nuisance alarms from cooking and delivers early warning.
• Interconnection with most First Alert and BRK alarms — compatible units sound together when one alarm activates.
• Battery backup — keeps the alarm powered during an outage.
• Perfect Mount bracket with a wide rotation range — helps secure and align the alarm during installation.
• Latching Alarm Indicator — shows which unit initiated an alarm or low-battery warning.

Smoke and carbon monoxide require different detection, and this combination alarm brings both functions into one hardwired unit. It is made for home alarm setups where compatible interconnected alarms can provide alerts across the home. Its battery backup also addresses power outages, while the installation bracket and visual indicator offer practical details for setup and identifying an alert source.

How does First Alert’s alarm help reduce cooking-related nuisance alarms?

Its Precision Detection advanced sensing technology is designed to reduce nuisance alarms caused by cooking while delivering early warning. The alarm combines smoke and carbon monoxide detection in one unit, so it provides both functions as part of a home alarm setup. It also meets new industry standards.

• One hardwired alarm combines smoke and carbon monoxide detection.
• Precision Detection is the sensing technology used in the alarm.

Can it connect with other smoke and carbon monoxide alarms?

Yes, it interconnects with most First Alert and BRK alarms. When one compatible alarm sounds, the other compatible interconnected alarms sound as well, helping create an alarm system throughout the home.

• Compatibility is with most First Alert and BRK alarms.
• The interconnected response is for compatible alarms in the system.

What helps with installation and power interruptions?

The alarm is hardwired and includes battery backup for continued protection during power outages. Its Perfect Mount bracket is designed to hold the alarm securely and allows a wide range of rotation to help with alignment and installation. The Latching Alarm Indicator visually identifies the unit that initiated an alarm or a low-battery warning, making it easier to locate the source within an interconnected setup.

• The bracket supports rotation for alignment.
• The indicator identifies an alarm or low-battery source unit.

The date printed on the product is its manufacture date, which identifies when it was produced. This is useful when reading the date on the unit and is distinct from an alarm event or low-battery indication.

This alarm suits households looking for hardwired smoke and carbon monoxide detection, battery backup, and the option to connect compatible First Alert or BRK alarms. Its combination detection, interconnection capability, and installation-focused bracket bring those functions together in one unit.
