Super easy to install and peace of mind that you won't have to worry for 10 years about replacing the battery. I ended up ordering several of them for my home. The functionality test is easy to perform and sound volume is very high. Hope I never have to find out how effective they actually perform in case of a fire. Review: Great 10 yr smoke detector - I was looking for a 10-year smoke detector that had a lithium battery since I am tired of changing out the 9 volt batteries every year. My other smoke detectors are also carbon monoxide combos and they are good for 10 years so everything will expire in 2035. It was easy to install. I could use the previous screws from my other first alert smoke detector but you have to use the new circular frame that comes with it or you won't be able to activate it properly. ## Features - First Alert's Precision Detection advanced sensing technology complies with new industry standards to reduce cooking nuisance alarms and provides early warning in the event of a home fire emergency. - 10-Year sealed battery eliminates battery replacements and low battery chirps for the life of the alarm - End-of-life warning lets you know when it’s time to replace the alarm - Test/silence button for efficient testing to ensure alarm is working properly ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | First Alert | | Style | Precision Detection | | Power Source | Battery Powered | | Color | White | | Product Dimensions | 5.6"D x 5.6"W x 2"H | | Alarm | Smoke | | Operating Humidity | 10-95% RH | | Sensor Type | Ionization | | Number of Items | 1 | | Manufacturer | Resideo | | UPC | 029054022929 | | Part Number | SMI110 | | Item Weight | 7.8 ounces | | Item model number | SMI110 | | Batteries | 1 Product Specific batteries required.

My other smoke detectors are also carbon monoxide combos and they are good for 10 years so everything will expire in 2035. It was easy to install. I could use the previous screws from my other first alert smoke detector but you have to use the new circular frame that comes with it or you won't be able to activate it properly. ### ⭐⭐⭐⭐⭐ There is a NO RETURN policy on these smoke detector *by M***. on January 29, 2026* 1 of the 5 I purchased didn't work. I found out the hard way that there is a NO RETURN policy on these smoke detectors. There is a yellow tab that you have to pull on and remove to activate these smoke detectors. After fooling around with it for awhile, I discovered that the mechanism associated with this pull tab did not activate the detector. I pushed and tapped on the mechanism, and finally got the satisfying CHIRP. It now works. So if you find that one of your smoke detectors does not activate, play around with those plastic pieces where the yellow tab was located. ## Frequently Bought Together - First Alert Smoke Alarm, 10-Year Sealed Battery Detector with Test & Silence Button, SMI110, 1-Pack - First Alert SMCO210, 10-Year Sealed Battery Combination Smoke & Carbon Monoxide Alarm with Slim Profile Design, 1-Pack - Kidde Carbon Monoxide Detector, Plug In Wall with AA Battery Backup, Test-Hush Button --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/602149046-smoke-alarm-10-year-sealed-battery-detector-with-test-silence](https://www.desertcart.jp/products/602149046-smoke-alarm-10-year-sealed-battery-detector-with-test-silence) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-24*
