Smarten up your home's smoke detection with the FirstAlert Smoke Detector, AC Power with Battery Backup. This full-featured smoke detector incorporates smart technology to reduce "nuisance alarms" and increase true alarm performance. It's cost-effective and reliable, keeping you safe around the clock. SMART TECHNOLOGY: The FirstAlert Smoke Detector includes multiple features that increase reliability and decrease the hassle that typical smoke detectors comprise. The dual ionization sensing chamber is more effective at detecting small particles produced by flaming fires. Sources may include paper or kitchen grease. The Smoke Detector is also interconnectable with up to 18 devices (12 can be smoke alarms), allowing you to protect your home with a detection system rather than individually operating units. LATCHING ALARM INDICATOR: As part of the Smart Technology system, the Latching Alarm feature remembers which detector in your home initiated an alarm. When interconnected in a series of detectors, the unit that triggered the alarm rapidly flashes its red LED indicator.
