Hardwired Combo Smoke & Carbon Monoxide Alarm w/ Battery Backup

The First Alert SC9120LBL Hardwired Combination Smoke/CO Alarm connects directly to your home electrical system. In the event of a power outage, the smoke/CO alarm is equipped with a 10 year lithium battery-backup. Integrating a Smart Technology system will reduce the likelihood of nuisance alarms triggering. A Latching Alarm Indication will remember which unit initiated an alarm. The perfect mount system features a gasketless base and a mounting bracket that keeps the alarm secure over a wide rotation range to allow for true alignment. Under normal conditions, you should not have to replace the battery for the life of the alarm.

Detects Smoke and Carbon Monoxide

Designed to meet the latest construction requirements, the First Alert Combination Smoke and Carbon Monoxide Alarm detects two threats: smoke and carbon monoxide. Lights on the face of the alarm will tell you what the threat is, and false alarms can be silenced with a single button.

Intelligent Sensing Technology Minimizes False Alarms

People sometimes disable a fire detector when it goes off due to cooking smoke or steam, even though in doing so they endanger themselves and their loved ones. Intelligent Sensing Technology is designed to distinguish between real fires and nuisances. This reduces the likelihood of false alarms significantly.

Sealed Battery Backup for Detection During a Power Outage

This smoke and carbon monoxide alarm is designed for hardwired installation, but it also features a ten year sealed battery backup that helps ensure continued functionality in the event of a power outage. The unit comes with a 10 year lithium powered battery backup and features a pivoting, easy-to-access battery drawer that allows you to replaces the battery without dismounting the alarm.

Connect to Other Alarms for Greater Coverage

This hardwired combination smoke and carbon monoxide detector can be connected to other compatible BRK or First Alert CO smoke detectors within a single-family residence. Once one alarm is triggered, all connected CO smoke alarms will sound. The latching alarm indicator on the CO smoke alarm automatically identifies which unit initiated the alarm–even after the conditions that set off the alarm have subsided.

Easy to Install and Maintain

The First Alert Combination Smoke and Carbon Monoxide Alarm integrates with existing wiring and features a universal mounting bracket that makes installing the unit quick and easy. Connection to AC power is simple with a Quick Connect wiring harness.

They are easy to install and switching the mounting brackets is very easy as long as you have an adequate ladder. The ladder part is the catch for most folks As soon as the house caches fire or we start grilling inside I will be certain to let you know how your alarms functioned

Perfect for apartments. Interconnected hardware and no batteries to change. Its been my experience tenants just rip them down when they start beeping.

Reviewer: Matthew Scott
The supplied wiring pigtail made swapping my old Firex detectors out for these a very simple task. I replaced two detectors in my home with these and am satisfied with their performance thus far. If your legislation requires the sealed, 10-year battery, then this will suit your needs perfectly.

Combo Smoke and Carbon Monoxide Alarm easy to install if you have any experience with electrical installation. Instructions helpful. Product is worth the extra money over the regular battery model. Now I don't have to worry about changing a battery or unit for 10 years.
