First Alert CO Detector with Battery Backup for Homes

The BRK CO5120BN Hardwired Carbon Monoxide Alarm with Battery Backup is designed to provide reliable detection of dangerous carbon monoxide (CO) levels in your home. This alarm features an advanced electrochemical sensor that accurately detects elevated CO levels, while a microprocessor helps minimize the occurrence of false alarms.

Installation is made quick and easy thanks to the convenient plug-in power connector, and the tamper-resistant mounting bracket lock ensures the alarm remains securely in place. In the event of a power outage, the 9-volt battery backup ensures continuous detection, giving you peace of mind.

Boasting an 85-decibel horn, the alarm will sound if CO levels become too high, and a warning chirp will notify you when the battery needs to be replaced. This alarm can be interconnected with up to 12 other First Alert or BRK hardwired alarms, as well as up to six compatible devices such as bells, horns, and repeaters, making it ideal for comprehensive coverage in large households or facilities.

The latching alarm indicator automatically identifies which unit in the series triggered the alarm, while the test/silence button allows you to easily check the alarm's functionality and mute false alarms. Backed by a 5-year limited warranty, the BRK CO5120BN is designed to provide reliable and long-lasting protection against the threat of carbon monoxide.

Carbon monoxide is a colorless, odorless, and deadly gas that can be emitted from various household sources, including furnaces, water heaters, fireplaces, and gas ranges. According to the Consumer Product Safety Commission (CPSC), at least one CO alarm should be installed near a home's sleeping area, and the BRK CO5120BN is well-suited for use in bedrooms, hallways, and basements.

The alarm's microprocessor-controlled design helps minimize the occurrence of nuisance alarms, while the single test/silence button allows for easy functionality testing and muting of non-threatening alarms. The battery drawer lock and mounting bracket lock also provide tamper resistance, ensuring the alarm remains secure and functional.

In addition to the carbon monoxide alarm, the package includes a 9-volt backup battery and a user's manual, making it a complete solution for protecting your home and family from the dangers of carbon monoxide. With its comprehensive features and reliable performance, the BRK CO5120BN Hardwired Carbon Monoxide Alarm with Battery Backup is an essential safety device for any household.
