About This Product
The First Alert Hardwire Dual Photoelectric and Ionization Sensor Smoke Alarm with Battery Backup is designed to provide peace of mind. The photoelectric and ionization sensors on this fire detector alert you to both smoldering and fast-flaming fires, offering comprehensive detection and early warning. The 85-decibel fire alarm can connect to other compatible hardwired fire detectors for larger spaces.

Features
  • Dual Sensors Detect Two Kinds of Fire: The First Alert Hardwired Dual Sensor Smoke Alarm features photoelectric and ionization sensors for increased detection and safety. The photoelectric sensor detects smoldering fires from objects like cigarettes burning on furniture or in trash cans, while the ionization sensor detects fast-flaming fires like erupting kitchen grease fires or combustibles. The dual sensors on this fire detector provide you and your family with the earliest warning possible.
  • Designed for Fewer False Alarms: Smoke from cooking or even shower steam can sometimes set off a smoke alarm. The photoelectric sensor on the First Alert Dual Sensor Smoke Alarm is sensitive to smoldering fires while reducing false alarms. The photoelectric sensor is smart enough to distinguish real threats from everyday activities, resulting in fewer false alarms.
  • Battery Backup for Detection in a Power Outage: The fire detector is hardwired, but it also features a battery backup to help ensure the photoelectric and ionization smoke alarm can still function in the event of a power outage. The fire detector requires two AA batteries, and comes with a low-power indicator to alert you when they need to be replaced. A one-touch silence/test button makes it easy to test the detector monthly or silence it during a false alarm.
  • Optipath 360 and Interconnectivity for Larger Spaces: The First Alert Dual Sensor Smoke Alarm with battery backup easily connects to other compatible hardwired alarms, making it the perfect solution for larger buildings such as institutions, dormitories, hotels and other multi-family dwellings that use single station smoke detectors. The smoke and fire detector includes patented Optipath 360 technology that provides 360 degrees of access to the detector, and its 85-decibel alarm is designed to be easily heard.
