Product description
The First Alert BRK SC-9120B Hardwired Combination Smoke and Carbon Monoxide Alarm uses electrochemical CO sensing technology and Ionization sensor for smoke detection. This hardwired dual CO smoke alarm can be connected to other compatible BRK or First Alert hardwired CO smoke detectors within a single-family residence. The latching alarm indicator automatically identifies which unit initiated the alarm--even after the conditions that set off the alarm have subsided. Using a 9-volt backup battery, the smoke and carbon monoxide detector can function even in the event of a power outage. Additionally, the CO smoke alarm features a single test and silence button, as well as indicator lights that let you know whether the danger is smoke or carbon monoxide. The tamper-resistant locking brackets and universal mounting brackets make installation easy.

- Reviewed in Canada on July 6, 2023Size: 1 PackVerified PurchaseOur older model of these were about 8 years old and didn’t have the replaceable battery so when they started beeping randomly here and there, we had no options but to change it up. It is nice how easy these are to replace for a hardwired option when the mounts are the same. This was the best place to buy them cost wise.

- Reviewed in Canada on August 19, 2022Size: 1 PackVerified PurchaseOrderd this one to replace my order version alarm system.
Item arrived on time, and takes me 2 mins to install it.
Working well, and I like it.
- Reviewed in Canada on November 30, 2021Size: 1 PackVerified PurchaseWe used the new alarm where we previously had a smoke detector, as they were both First Alert products, the existing collar fit the new alarm which made installation easy.
Our previous carbon monoxide alarm expired so having the double alarm in one unit is great. We haven't had it go off yet, and hopefully it never will, but it is there if needed.

4.0 out of 5 stars Easy to replace
Size: 1 PackVerified PurchaseThese things are apparently programmed from the factory to go off only in the middle of the night. The beeping is just loud enough that you can't just sleep through it. And the darn beeping occurs with too much of a delay so that when you do get up to find it, it takes way too long in the middle of the night to triangulate and figure out which one you have to take down so that you can go back to sleep and deal with it in the morning. It's like some torture game of hide and seek. By the time you figure out which one is malfunctioning, you've been awake and annoyed long enough that you're pretty much now wide awake. Is it some kind of North Korean/Russian plot to destroy the lives of normal mundane US citizens through intermittent sleep deprivation? First the election, now this.
One chirp every 3-4 minutes means that the 9V back up battery is dead. Three chirps that go off every 3-4 minutes indicates that the detector as a whole is malfunctioning. Replacing the battery doesn't do anything. I've tried dusting them out with an air gun but usually doesn't work. Most authorities recommend replacing these things about ever 5-10 yrs or so. So far, about 5 years is about how long these have lasted in my house, and over the past several months I've been replacing one after the other. I've lost enough sleep on random nights over the past several weeks that I'm just going to replace all the rest of the ones in my house and just move on with my life.
As a bonus annoying factor, the 9V battery lasts about 4 yrs. I just went through and replaced all the batteries less than 9 months ago, and now I'm going around replacing the whole darn thing. So that was a nice waste of money, especially since the new detectors come with new 9V batteries and now I have a small stockpile of partially used 9V batteries.
The only good thing is that they are easy to replace, and much cheaper on Amazon than the local brick and mortar stores. And thankfully, I haven't had one go off because of a house fire or carbon monoxide buildup, so I can't comment on their effectiveness, but I guess it's one of those things you just have to assume will work when it needs to... like the airbag in your car.
