Utilizes both ionization and photoelectric smoke sensors for optimal performance Intelligent sensing technology reduces non-emergency or nuisance alarms Operates on 2 AA batteries (included) Optimized sensor performance for the most nuisance-resistant dual sensor alarm on the market First Alert SA320CN Dual Sensor Smoke Alarm; Utilizes Ionization & Photoelectric Smoke Sensors; Intelligent Sensing Technology Reduces Non-emergency Or Nuisance Alarms; 10-Year Limited Warranty. When alarm is in “normal operation”, there is a flashing Green LED once a minute and there is no audible alarm. No one wants to think about a fire in their home, but being prepared and recognizing signs of danger early can help keep you and your family alive and safe. The First Alert SA320CN Double Sensor Battery-Powered Smoke and Fire Alarm is equipped to detect smoke particles caused by both flaming and smoldering fires.
The First Alert Double Sensor Smoke and Fire Alarm: Detects both flaming and smoldering fires with dual sensors. Emits a loud 85 dB alarm for ample warning. Minimizes false alarms by detecting differences between real emergencies and non-threatening conditions.
Dual Sensor Technology For Maximum ProtectionWhile all smoke alarms are designed to detect smoke, different sensing technologies react differently to certain types of fires. This 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. Loud Alarm and Reliable Construction for Peace of MindThe loud, 85 dB alarm gets your attention quickly, so you can get out quickly or contain a minor fire before it spreads. Plus the smart dual sensor helps the detector recognize the difference between non-threatening conditions and real emergencies, so false alarms are minimized. This smoke detector meets the UL 217 standard for dual-sensor home smoke detectors, which means that it has passed tough quality-assurance tests and can be depended on to offer reliable protection. Mute and Easy Battery Access for Safety and ConvenienceThe mute button can be used to test the alarm function, helping you ensure that your home and family are always protected. This smoke detector is powered by two standard AA batteries (included). And, because a smoke detector is only effective if it is properly maintained, you'll appreciate that the EZ access battery door means there's no need to remove the alarm from your ceiling when it's time to change the battery. This smoke detector's neutral, white finish blends in with your décor, and the unit measures just 5.7 x 5.7 x 2.8 inches. It is backed by a limited 10 year warranty. Enhanced Performance With optimized sensor performance, this smoke detector is the most nuisance-resistant dual sensor alarm on the market.

As a professsional firefighter/paramedic for nearly 13 years, I see a lot of fires. I do know that most detectors out there are NOT dual sensor....they are mostly only ionization detectors that detect flame. Remember it's usually not the fire that will kill you, it's the smoke and it's deadly component carbon monoxide that will end your life. Photoelectric detectors detect these smoke particles and alert you.......ionization types rarely do if it's a slow smolder..
