Protect Your Family with patented Universal Smoke Sensing and Smart Alarm® Technology

Our patented Universal Smoke Sensing Technology is based on years of research into fast and accurate detection of threats from fast flaming and slow smoldering fires. These smoke alarms can distinguish between cooking smoke and real fire, significantly reducing nuisance alarms. Some alarms also include Carbon Monoxide detection in the same unit, and then back many of our alarms with 10-Year Permanent Power™ Sealed Battery, which never needs replacing.
