Dual Sensor Smoke and Fire Alarm with 10-Year Sealed Battery

The First Alert SA3210 10-Year Battery Dual Sensor Alarm provides early warning of both flaming and smoldering fires. Additionally, its intelligent sensing technology is designed to cut down on nuisance alarms from cooking smoke or other common false-alarm triggers. A single button both silences and tests the smoke detector for simple operation. The built-in 10-year lithium-ion battery provides continuous power, with no need to ever worry about changing the battery over the lifetime of the smoke detector, and it can be easily installed anywhere without wires.

Dual Sensors Detect Different Types of Fires

This First Alert Smoke and Fire Alarm comes equipped with two different sensors to offer the earliest possible warning of a fire. The ionization sensor detects flaming fires, such as grease fires or wastebasket fires, while the photoelectric sensor detects smoldering fires, such as when a lit cigarette ignites clothing or upholstery. Both sensors work together to provide complete smoke and fire detection.

Intelligent Sensing Technology Minimizes False Alarms

People sometimes disable a fire detector when it goes off due to cooking smoke or steam, even though in doing so they endanger themselves and their loved ones. Intelligent Sensing Technology in the First Alert Dual-Sensor Smoke and Fire Alarm is designed to distinguish between real fires and nuisances, reducing false alarms significantly so there is never a need to disable the alarm.

Ten Years of Smoke and Fire Protection

This smoke and fire alarm is powered by ten year sealed lithium batteries. The batteries will not have to be replaced during the span of the alarm's ten year operation. Dual sensing technology and a decade's worth of protection provides an elite defense in alerting others to the presence of smoke and fire in the home.

Ionization smoke alarms are designed to identify fires that are defined by their rapid flaming qualities. These fires are characterized by their ability to generate and combust at an advanced speed (ie. kitchen grease fires or fires fueled by paper burning in a wastebasket).

Photoelectric smoke alarms specialize in detecting fires that are indicative of their slow smoldering properties. These fires are defined by their propensity to produce large smoke particles that can smolder for hours before bursting into larger flames (ie. those caused by cigarettes or candles burning on couches or bedding).

For maximum protection and full coverage from all types of fires, your best option is to use a smoke alarm that features both photoelectric and ionization sensing technologies.

Again, ordered on 26July,2019, but just installed today 6 Oct.. Went very well. Was pleasantly surprised when I found out I could use the anchors from the old Kidde dual smoke alarms. I originally purchased the First Alert ones because I wanted a dual sensor smoke alarm with a 10 year battery which Kidde did not have. Thank you First Alert for selling one. I appreciate your thoughtfulness in this matter. Again thank you very much.

I purchased this unit to replace an older model that reached its maturity date. This one has a 10 year battery so I don't have to hassle with changing batteries. So far so good. Looks like a winner!

In California, the law requires 10 year batteries on non-wired detectors, and this is one of the few with dual sensors photoelectric and ionization - you need both types of detectors, why not have both in the same unit. Customer service is very friendly and helpful, plus shipping was included. What more can you ask for?

Easy to install to replace an older, ionization only smoke alarm. The base did have to be installed as the new alarm did not fit in the older first alert base. It was not, though, expected to fit. But it would've been a plus.
