First Alert provided samples to facilitate this review; however, all opinions are my own.

My husband has been in the fire service for 35 years, so we’ve got quite a collection of smoke detectors. When a new type hits the market, he checks it out so that he’s up on what’s available and how they work.

First Alert 10-Year Detector SA3210 - First Alert 10-Year Alarm: Give the Gift of Peace of Mind @FirstAlert ad

This new First Alert 10-Year Alarm is a smoke and fire alarm that has both photoelectric and ionization detectors. Having both is crucial because photoelectric detects a slow smoldering fire while the ionization detector relies on a rise in temperature to trigger it. This dual alarm takes care of both, and that’s two of the three types of alarms every family needs to protect them. The third is a carbon monoxide detector.

First Alert Dual Sensor Smoke & Fire Alarm: Home Coverage

Now that you know the three types of alarms you should have, it’s essential that you have adequate coverage in your home. Alarms like this First Alert Dual Sensor Smoke & Fire Alarm provide diagrams like the one below which shows the proper placement of and the reasons for multiple units. My husband would also tell you to put them in your crawlspaces because, without an alarm, a fire has a chance to take hold before breaking through to a location where a detector is present.

What makes this dual alarm special that it’s powered by a 10-year lithium power cell that never needs replacing. At the end of its life, the unit is disposed of. The battery can’t be removed so you’ll never have to worry that someone took the batteries out to silence the alarm or borrowed them to power something else. Nor will you have to worry about the batteries being dead.  My husband has had many homeowners who’ve experienced a house fire tell him that these are reasons why their smoke detectors failed to work – it boils down to human error.

This detector is easy to install, and since it doesn’t need biannual battery replacements, it’s perfect for my inlaws home. Their house has very high ceilings that make maintaining a detector a job no one looks forward too.

My husband installed the detectors with the included mounting hardware in just a few minutes. They have been protecting his parents for a few weeks now, and they’re working great, and there have been no false alarms to report. My husband will visit them once a year to clean and test them to be sure they continue to work well.

Now they’re installed, we feel good knowing that their alarms are powered and ready to alert them should a fire break out. We’re trusting their safety and my husband’s childhood home to the First Alert SA3210 Dual Sensor Smoke and Fire Alarm with 10-Year Sealed Battery.
