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 slightly more sensitive than Photoelectric Sensing Technology at detecting these sorts of flaming fires.
This is a battery powered alarm – powered by a sealed, ten year lithium battery 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. (Meets California 10 Year Smoke Alarm Requirements.)

Item was just as described and arrived quickly.

Great price, quick shipping. Unit seems as described, but we will have to see if the battery does last 10 years. One annoying thing is the absurdly tiny font in which instructions were printed.

Very good price and fast shipping
These Dual Sensor 10 year Alarms can be pricey but found the best price here. The shopping experience was easy and delivered direct to my door. Now I hope I never use them.

I was going to buy this from Amazon, but was really confused by all the models and descriptions. When I found the SmokeAlert website, it was FAR easier to use. As a long-ago volunteer fireman, I was elighted to see the business was firefighter-owned. The alarm I selected was very well-packed and shipped quickly. WIll be back for more!

I just purchased a home with the original detectors in place. Being 13 yrs old, I wanted to replace them and did some research on which model I wanted. This fit the bill… detects both smoke and flames and has a 10yr sealed battery. No more middle of the night beeps! I had 6 installed in my home and my neighbor had 7 replaced in hers. So far, so good!
Harrell Perlman –
Alarms were shipped quickly and packaged very well. The price was good enough to allow purchase of 2 alarms versus just one, which is a lot safer. Overall an A+ experience.

This is my second time ordering smoke detectors from Smoke Alert. I ordered two more First Alert smoke and fire alarms, and just like the first order, the price of the alarms was the best I could find on the internet. Also, shipping was very fast; it only took three days from the east coast. I couldn’t be happier.

Fast response to inquiry and fast delivery. Best price around.

The Customer Service Rep answered all my questions and was very helpful. I purchased 2-dual sensor smoke alarms with 10-yr batteries and am very happy with the product.
Paul Whitman –
Smoke alarms were back-ordered and noted on website. I called and SmokeAlert said they were back in stock. Ordered, received and installed. Perfect!
Mark Javorski –
Best deal and decent ship speed
I wanted the dual sensor smoke alarm. Installing was very easy and hope it never makes a sound!
Very pleased with the product and prompt, excellent service.
I ordered on 11/28/2020 and it is now 12/12/2020 and I haven’t received my order.
***REPLY: The shipping services are having an extremely difficult time due to COVID and now a massive increase in holiday shipping (I was told the amount of packages being shipped 400 times what it was last year!). We definitely apologize for the delay in shipping – I wish we could make the carriers move faster, but they are now understaffed and overwhelmed.
Best price out there, fast shipping
Just the protection I need and don’t have to worry about remembering to change the battery every year. Feel very confident about this product and hope I never have to review it’s performance. Purchased this unit from this company because it is owned and operated by firefighters. Who better to trust? Thank you. Keep saving lives.

You are asking for a review for items that have not even been shipped out from the US. I have been writing in to enquire but have been given vague answers. I paid for the items on 21 April 2021 but in tracking, USPS says label has been created but items from Smoke Alert have not been received to start the delivery process. I am totally appalled by the way Smoke Alert has handled my purchase and I am being charged almost a month’s salary (Malaysia) for items that has not even been sent to USPS and non-existent delivery. Kindly investigate and get my purchases out to me asap.
