Customer Reviews For The BRK Hardwired Combo Smoke and Carbon Monoxide Alarm with 10-Year Battery Backup
No need to climb ladders again to change batteries every 6 months. Product fitted perfectly on replacement smoke detector brackets.
The exact product that I was looking for. Replaces 10 year old smoke alarm only devices. This time with with 10-year life batteries. A score for being forward thinking and safety conscious by not having to climb up and down ladders twice a a year to replace batteries. These are all 120V devices and interconnected with other First Alert/BRK devices. Installation was a breeze since the wiring is exactly the same as the previous devices.
These alarms installed very easily to replace the similar FirstAlert alarms I had that had 9-volt battery backup electric adapter was the same, twisted right into the existing space. But now, no more battery changes until I have to replace them 10 years from now very happy!
House came with 9120B AC powered smoke detectors. Ordered replacements since its been over 10years and decided to upgrade 2 locations to a CO combo unit. So glad that I was able to use existing cabling for the SC9120LBL, as well as the smoke only model. Install for all 7 locations was under 30minutes.

I'm replacing my old hard wire battery operated smoke detectors with new detectors that are guaranteed for 10 years with no climbing up and down ladders every 6 month. Well worth the investment for a 10 room townhouse. It took no time to replace and install them.
Good company, good product good service.
Nice that they fit in the older model template
One of the top and best Choice in the market. So proud and happy
First time I bought from this manufacturer the pricing was good, selection was good and the product was delivered quickly.
These work great and the best part is they are still manufactured and available - A VERY good thing for a wired detector!
Love the hard-wire + 10-year battery combo.
Replaced very old First Alert Smoke Alarms with new Smoke and Carbon Monoxide Alarms with 10 year battery backup. I was told it would be easy - I replaced 5 units in 30 minutes and everything worked perfectly. No problems - great new units!
Easy to order, quick delivery, easy to switch out prior hardwired/battery back-up detectors to new hardwired/10yr battery backup detectors. Very happy with this product.
These are easy to install to replace the 9-volt units that are not to code any longer.
Easy Install, no maintenance, what's not to love!
It easily replaced the First Alert smoke detector previously installed.
Easy to install
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.
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.
10-Year Lithium Battery Backup
The First Alert SC9120LBL Hardwired Combo Smoke and CO Alarm features a built-in 10-year lithium battery backup that provides continuous power for the life of the detector. An end-of-life timer lets you know when the device should be replaced.
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.
