## Description

The First Alert SM210 10-Year Sealed Battery Smoke Alarm with Slim Profile Design is equipped with First Alert's Precision Detection advance sensing technology and meets new industry standards. This slim profile smoke alarm is easy to install, and the 10-year sealed battery means no battery replacements are required.

Review: I needed to replace one wired and one battery smoke alarm. The original First Alert unit was no longer available, so we opted for the recommended unit. It arrived in a plain cardboard box, but the device was sealed. We had to change the mounting bracket to adapt to the newer design, but the size and function remained the same. All in all, a good quality alarm that will hopefully last the same 10 years as the original.
Review: Easy to install. These are sensitive, and will detect the slightest danger of smoke. I am impressed with the quality, and how well it works! 10 year sealed battery, and it's durable.

### ⭐⭐⭐⭐ Review
*by S***U on 17 June 2025*

I've had these smoke detectors in my home for about a year now, and two of them started to malfunction. They started alarming (NOT chirping), in the middle of the night. One of them alarmed a few times and stopped after I took it down. The other alarmed every couple of hours until I took it down. The following night, it started to alarm again, but it was constant. I tried to silence, reset, and clean the detector, nothing would turn it off so I eventually deactivated it before I went insane. I called First Alert's product support to let them know what was happening, and they are sending new units to my house. I am incredibly satisfied with their customer service, but wish I didn't have to deal with the malfunctioning alarms in the first place.
