The fist alert Sa3210 dual sensor ten year alarm makes use of both ionization and photoelectric sensors to offer the earliest possible warning-regardlesss of the type of fire. Sometimes a fire can smolder for hours before erupting into flames. Photoelectric sensing technology is more sensitive than ionization sensing technology at detecting these sorts of smoldering fires, like those caused by cigarettes burning in couches or bedding. Other fires erupt into flames quickly, like kitchen grease fires or fires fueled by paper burning in a wastebasket. Ionization sensing technology is generally more sensitive than photoelectric sensing technology at detecting these sorts of flaming fires. This alarm is powered by sealed, ten year lithium batteries to provide continuous protection for ten year without battery replacement. Single test/silence button mutes unnecessary alarms and tests function. End of life timer sounds when it's time to replace your alarm. First Alert Sa3210 meets UL217 standards and complies with legislative requirements for 10-year battery operated smoke alarms. This product includes mounting hardware and is backed by a 10 year limited . ## Features - The front cover design of the alarm may vary but product function remains the same - Complies with all current 10 year legislation in U.S. states cities where required - The 10 year lithium ion battery offers continuous power for the life of the alarm and provides continued monitoring even if there's a power failure - Loud 85 decibel siren sounds to alert you to danger, Hardwired alarm includes battery backup for power outages - To ensure complete protection make sure to place one on each level of your home and in each bedroom - Meets UL217 standards and complies with legislative requirements for 10 year battery operated smoke alarms - Equipped with a dual photoelectric and ionization smoke sensor to quickly detect both fast burning and smoldering fires - First Alert has been the most trusted brand in home safety since launching the first residential smoke alarm in 1958 (Based on a First Alert Brand Trust Survey in February 2018) - First Alert warranty extends ten years from the date of purchase with proof of the original sales receipt and the product should be free from defect in material and workmanship ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B011O2WVCW | | Alarm | Audible | | Best Sellers Rank | #510,293 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #393 in Smoke Detectors & Fire Alarms | | Brand | First Alert | | Built-In Media | smoke alarm, batteries | | Color | White | | Customer Reviews | 4.1 out of 5 stars 867 Reviews | | Global Trade Identification Number | 00029054015518 | | Item Dimensions D x W x H | 2"D x 5"W x 5"H | | Item Type Name | Smoke and Fire Alarm | | Item Weight | 10.4 ounces | | Manufacturer | First Alert | | Manufacturer Warranty Description | 10 Year Limited Warranty | | Mfr Part Number | SA3210 | | Model Number | SA3210 | | Number of Items | 1 | | Power Source | Battery Powered | | Product Dimensions | 2"D x 5"W x 5"H | | Product Style | Standard Detection | | Sensor Type | Photoelectric | | Style | Standard Detection | | UPC | 029054015518 | | Unit Count | 1 Count | ## Product Details - **Alarm:** Smoke Alarm - **Brand:** First Alert - **Color:** White - **Item Weight:** 11.2 ounces - **Operating Humidity:** 10-95% RH - **Power Source:** Battery Powered - **Product Dimensions:** 5.4"D x 5.4"W x 1.9"H - **Sensor Type:** Ionization - **Style:** Precision Detection - **Unit Count:** 1 Count ## Images ![FIRST ALERT Dual Sensor Smoke and Fire Alarm, SA3210 , White - Image 1](https://m.media-amazon.com/images/I/71MnTI0sgPL.jpg) ![FIRST ALERT Dual Sensor Smoke and Fire Alarm, SA3210 , White - Image 2](https://m.media-amazon.com/images/I/81WxlVsQYRL.jpg) ![FIRST ALERT Dual Sensor Smoke and Fire Alarm, SA3210 , White - Image 3](https://m.media-amazon.com/images/I/51ZOJ2WEkTL.jpg) ## Questions & Answers **Q: I recently purchased three of these smoke alarms from Amazon. Can you tell me how high up on the wall the alarm should be installed as I do not want to install on ceiling. I specifically purchased these as they can be ceiling or wall mounted. Thanks.** A: The instructions that come with the unit duplicate what I have read from several Fire Department sources: you can place your unit on the ceiling, but AT LEAST 4 inches (10cm) from the wall. If you want to mount it on the wall, mount it MORE THAN 4 inches (10cm) BELOW the ceiling, but NO LOWER than12 inches (30cm) below the ceiling. It has to be high enough up the wall to "smell" the smoke, but that 4 x 4 inch (10cm x 10cm) area where the wall meets the ceiling can sometimes harbor a "dead zone" of still air where the smoke would NOT reach the detector quickly enough during a fire to warn you in time. Thus, do NOT mount your detectors too close to where the wall meets the ceiling. **Q: Is this detector a photoelectric or ionization type?** A: Please check with your local authority having jurisdiction. Also you can check with NFPA online. Ionization smoke alarms are generally more responsive to flaming fires. How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm. Download this chart on ionization smoke alarms (PDF, 943 KB). Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”). How they work: Photoelectric-type alarms aim a light source into a sensing chamber at an angle away from the sensor. Smoke enters the chamber, reflecting light onto the light sensor; triggering the alarm.

It always seems to start in the middle of the night. I twist the unit off the ceiling and do a battery swap and have it back on the ceiling in less than a minute, craw back into bed before really waking up. It's not a pain to replace the batteries, it's very easy. Simply slide the tray out and pop new ones in. The batteries fit snuggly in the compartment and there are tabs that allow you to push the batteries out by applying pressure with your thumbs from the back side. There is an optional screw hole to make the battery compartment tamper resistant. This prevents people from easily taking the batteries to power their remote controls or whatever. When fire marshals inspect fire related deaths it's not uncommon to find the smoke and fire detectors had no batteries installed. This simple, optional, screw might seem like "a pain" to some people, but it's an easy way to save your life. This is a great unit. I have 6 in my house and I highly recommend them to everyone. **Q: 5 or 10 year warranty? Picture & Description say 10, Features says 5.** A: Package says 10 year limited warranty. It's cheap, easy to install. This is my second one. Had first one for 8 years. ## Frequently Bought Together - FIRST ALERT Dual Sensor Smoke and Fire Alarm, SA3210 , White - First Alert CO605 Plug-In Carbon Monoxide Detector with Battery Backup , White - First Alert CO710 Carbon Monoxide Detector with 10-Year Battery and Digital Temperature Display , White --- ## 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.ph/products/24187174-first-alert-dual-sensor-smoke-and-fire-alarm-sa3210-white](https://www.desertcart.ph/products/24187174-first-alert-dual-sensor-smoke-and-fire-alarm-sa3210-white) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-11-13*
