While all smoke alarms are designed to detect smoke, different sensing technologies react differently to certain types of fires. The Fist Alert SA3210 Dual Sensor Ten Year Alarm makes use of both ionization and photoelectric sensors to offer the earliest possible warning--regardless 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 years 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 warranty.

Reviewer: MK
I ordered a three-pack of these, and they were very easy to install. I like the idea of not having to worry about changing the battery every six months and that these are dual sensor alarms capable of sensing both smoldering and quick burning fires.

I bought three of these and the delivery came as expected. Installation was very easy and so far there have been no false alarms. Just what I had hoped for.

Reviewer: Ann Lucas
I have owned several rental properties the last 20 years, and I have not found one tenant who will replace the batteries when they start chirping. I even provide the batteries, and they just are too busy or lazy to do the responsible thing. I was so pleased to find the smoke/fire alarms that do not require the batteries to be changed. It makes me feel so much better as a landlord. I hope the alarms are good for 10 years as advertised, but even five or six years would make me happy at this point.

Reviewer: Gordon  Arnold
Has all the features I want. Dual fire sensing capability and ten-year life. I have separate CO2 detectors but wanted a single device to cover fire threats. This is it.

Best smoke alarm out there. Best in class detection with dual sensors and no maintenance with the 10-year Lithium battery. Easy to install and highly recommended!
