Keep your family safe with this First Alert SM310 smoke alarm. The best part? The battery is sealed inside and lasts for 10 years – no more changing batteries every year or dealing with annoying low-battery chirps in the middle of the night! It uses dual sensors (photoelectric and ionization) to detect both fast-flaming fires and slow, smoldering fires, giving you early warning either way. It also has advanced technology to reduce false alarms from cooking (so maybe your toast won't set it off every time). There's a test/silence button for easy checking, and when the alarm reaches the end of its life after 10 years, it'll let you know it's time for a replacement. Easy to install on your ceiling or wall. Every home needs working smoke alarms, and this one offers reliable, hassle-free protection for a decade. A must-have for bedrooms, hallways, and kitchens.
