About this product

The First Alert® SMI100 Battery-Operated Smoke Alarm is equipped with our Precision Detection advanced-sensing technology and meets the latest industry standards. The result is fewer cooking nuisance alarms and better smoke detection from synthetic materials which burn hotter and faster. That early detection allows you and your loved ones more time to escape safely. The battery-operated basic smoke alarm is easy to install, features a single test/silence button for simple operation, and the front access battery compartment makes for easy battery replacements.
