Siterwell GS886F-H02 10-year Battery Hardwired Interconnected Smoke & Carbon Monoxide Combo Detector

It took me a bit to get this installed, it didn’t want to attach to the wall plate properly but I was able to finally get it. The alarm is loud, I have no doubt that it’ll wake us up if we happen to be asleep or anything else. I like the simple design and the voice feature is a nice addition compared to previous ones that I’ve had. I haven’t had to actually see it in action yet (I hope I never do), but I have done the test on it and there was no issues.

This SITERWELL hardwired smoke and carbon monoxide detector packs a serious punch when it comes to safety and convenience. The built-in 10-year battery backup means you’re protected even during power outages without the hassle of battery replacements. It uses both photoelectric and electrochemical sensors for accurate detection and meets the newest UL standards, which is reassuring. I especially like the reduced nuisance alerts—it won’t scream at you every time you cook a steak. The bilingual voice alerts are a thoughtful touch, especially for households with French speakers, and the ability to interconnect up to 18 units ensures whole-home coverage. Installation is straightforward, and the build feels solid. For a single pack, it’s an impressive value with long-term peace of mind built in.

I started upgrading all my smoke detectors to dual alarms for carbon monoxide.I like the fact that it was super easy to switch them out. The wiring was straightforward and the included 10 year battery means I don’t have to worry about this thing for a long time.I didn’t fully test it with carbon monoxide and I hope I never really have to but the smoke sensors tested well.You never know you need to until it’s too late.

My husband had no problem installing this hardwired smoke detector (I must say, he does have professional electrical knowledge). I feel like the instructions were written well enough a novice could install it. The fact that we won't have to worry about changing the battery for 10 years is amazing! Before getting this smoke detector I'd actually removed our old smoke detector because the battery kept dying after a couple of months. I'm so glad we have detectors back up, but also don't have to worry about the battery beeping in the middle of the night. The smoke detector works well. I love the voice alert. I think the peace of mind and battery life on this smoke detector make it an excellent value at this price.

It was time to change my smoke/co detectors. I saw this one on Amazon and like the idea that you don't have to change the batteries cuz I hate when those things start beeping and saying low battery in the middle of the night. This detector is a little bigger than my Kidde detectors and it seems to be well made. I had two issues with installing this one. Unlike other smoke/co detectors that I've installed, you can't just twist this onto the bracket from at any position when you place it on the bracket. The proper slots have to line up exactly with the matching brackets on the plate. I knew that would be an issue, blindly stabbing the detectors onto the bracket and trying to get things to line up so I made a little red sharpie mark that I could use to line up and that made it easier to match up and twist on. The other issue I had with it was that the wiring pigtail that snaps into the back of the detector. The locking tab would not grab the slot as if it wasn't being pushed in far enough. I eventually got I got it to stick. There was another part of the mounting bracket that I was confused about so I just read the instructions...duh...There is a feature to twist the detector onto the bracket so it cannot be removed easily, tamper proof... an example of a rental or such. There's a little tab that has a little scissors icon next to it and you have to basically break this little tab off so it is easy to remove if you ever have to remove it. I'm glad I realized that before I put it up and locked it on there. Other than the problems mentioned, the detector tested well and works fine... just hopefully I'll never need to have it go off for real. I gave it four stars due to the problems I mentioned.
