Siterwell GS886F-H02 Hardwired Interconnected Smoke & CO Detector with 10-Year Backup Battery

Received in good condition. Straightforward installation. Small printed instructions a bit of a challenge. Routine setup.

After installing the detectors and only for one day, one of the detectors had problems. It started to chirp every10 seconds. The lights indicated everything was good.

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.
