Review: There is a NO RETURN policy on these smoke detector - 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. Review: 1-star reviewers NOT FOLLOWING INSTRUCTIONS! - Some of the people giving 1-star are not reading the instructions. The smoke detector will not activate until: 1. You pull and remove the yellow tab, AND 2. You twist and install it into the mount assembly I think people are trying to press "test" before it's installed and assuming they don't work. I ordered 4, and all of them worked once installed. Also, they were manufactured very fresh, I think only 2 months ago from the time that I ordered which is great. Comes with the mount for the ceiling as well as the screws you will need. Don't use previous mounts because it might not be compatible, and you NEED the mount because thats also what activates the alarm. THE TEST BUTTON WILL NOT WORK BEFORE INSTALLATION! To be clear, the battery in these is non-removable. It has an internal battery and when it dies, you replace the entire unit. Modern units nowadays have an end-of-life alarm at 7-10 years anyways, so this is fine. Totally worth the couple of dollars more not to have to change 9V batteries every few years. I believe this version of the unit are NOT interconnected with each other, and they are NOT hard wired either. I dont mind because the battery lasts 10 years so I dont see why hardwiring is required. I just tucked my power wires above into the ceiling. ## 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 | |---------------|-------| | ASIN | B0CJMQH3WJ | | Alarm | Smoke | | Best Sellers Rank | #1,278 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #6 in Smoke Detectors & Fire Alarms | | Brand | First Alert | | Color | White | | Customer Reviews | 4.0 out of 5 stars 1,073 Reviews | | Item Dimensions D x W x H | 5.6"D x 5.6"W x 2"H | | Item Type Name | Smoke Alarm | | Item Weight | 8 ounces | | Manufacturer | Resideo | | Mfr Part Number | SMI110 | | Model Number | SMI110 | | Number of Items | 1 | | Operating Humidity | 10-95% RH | | Power Source | Battery Powered | | Product Dimensions | 5.6"D x 5.6"W x 2"H | | Product Style | Precision Detection | | Sensor Type | Ionization | | Style | Precision Detection | | UPC | 029054022929 | | Unit Count | 1 Count | ## Product Details - **Alarm:** Smoke - **Brand:** First Alert - **Color:** White - **Item Weight:** 8 ounces - **Operating Humidity:** 10-95% RH - **Power Source:** Battery Powered - **Product Dimensions:** 5.6"D x 5.6"W x 2"H - **Sensor Type:** Ionization - **Style:** Precision Detection - **Unit Count:** 1.0 Count ## Images ![First Alert 10-Year Battery Smoke Alarm - Image 1](https://m.media-amazon.com/images/I/71UD83zU2SL.jpg) ## Available Options This product comes in different **Pattern, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 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.

Unfortunately, it failed immediately. As soon as we installed it, the alarm sounded continuously and could not be silenced, despite following the manufacturer’s instructions. It was clearly defective right out of the box. What made the experience even worse was discovering that I couldn’t easily obtain a replacement or a refund. A smoke alarm isn’t a luxury item—it’s a critical life safety device. When a product arrives defective, customers should not be left without protection or forced to spend additional time and money finding another option. I had to remove the defective unit and purchase a different brand to ensure my home was protected. Based on both the product failure and the lack of customer support, I cannot recommend this smoke alarm. ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/602149046-first-alert-10-year-battery-smoke-alarm](https://www.desertcart.gr/products/602149046-first-alert-10-year-battery-smoke-alarm) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-23*
