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.
First Alert Photoelectric/Ionization Smoke and Fire Alarm SA3210
* Meets California, New York and New Jersey 10 Year Smoke Alarm Requirements
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.
