Features

The First Alert SC9120LBLA 10-Year Battery Backup Hardwired Smoke and CO Alarm is designed to help promote household safety. This hardwired smoke and CO detector uses an ionization smoke sensor to reliably detect smoke from hot, fast-flaming fires, and an electrochemical sensor to detect carbon monoxide. When smoke or carbon monoxide is detected, a loud 85-decibel alarm alerts you to the threat.

    • Built-In 10-Year Battery
    • Electrochemical Sensor Monitors CO Levels
    • Ionization Sensor Reliably Detects Flaming Fires
    • Works in Tandem with Other First Alert Alarms

  • Built-In 10-Year Battery

The First Alert SC9120LBLA 10-Year Battery Backup Hardwired Smoke and Carbon Monoxide Alarm features a built-in 10-year lithium battery that provides continuous power for the life of the detector. An end-of-life timer lets you know when the device should be replaced.

  • Electrochemical Sensor Monitors CO Levels

The alarm also features an advanced electrochemical sensor that detects carbon monoxide leaks from a variety of sources, such as faulty fuel-burning appliances, blocked chimneys, and cars left running in the garage. Carbon monoxide can’t be seen, smelled, or tasted in the air, and it is the leading cause of accidental poisoning deaths in America. By placing carbon monoxide detectors on every floor of the home and in each sleeping room, you can help protect your family from the danger of carbon monoxide.

  • Ionization Sensor Reliably Detects Flaming Fires

The First Alert 10-Year Battery Backup Hardwired Smoke and CO Alarm comes equipped with an ionization sensor to provide the earliest possible warning of a fast-flaming fire. The sensor is optimized to detect flaming fires, such as those caused by paper, kitchen grease, and other fast-combusting materials.

  • Works in Tandem with Other First Alert Alarms

In addition to functioning independently, this smoke and CO alarm can also integrate with up to 12 other First Alert or BRK hardwired alarms for coverage of larger spaces. This detector also integrates with up to six other compatible devices, such as bells, horns, and repeaters. If one alarm in the series is triggered, they will all sound. The alarm features a latching indicator to identify which unit triggered the alarm, alerting you to the area of danger.
