Take control of a safer home.

The advanced capabilities you need to manage your home safety with confidence. This smart alarm provides double the detection of smoke and carbon monoxide (CO), combining additional sensing capability with the convenience of a device that handles two important jobs instead of just one. It’s also equipped with the reliability of a 10-year,* sealed-in lithium backup battery, so you can count on smoke and carbon monoxide detection – even if the power goes out.
