First Alert Battery Smart Smoke Alarm

The First Alert® SM210V 10-Year Sealed Battery Smoke Alarm with Voice and Location Alerts helps guide your escape to safety. It utilizes First Alert's Precision Detection advanced sensing technology that complies with the latest industry standards to reduce nuisance alarms and detect smoke from synthetic materials. Early warning is critical because today’s materials burn hotter and faster and may result in less time for a safe evacuation. It also features a sleek, contemporary design that is half the depth of a standard alarm - helping the device seamlessly blend into the wall or ceiling. The SM210V detector provides reliable and convenient protection with its built-in 10-year sealed battery, eliminating low battery chirps and the cost of battery replacements for a decade. The end-of-life warning will alert you when it is time to replace the detector.
