Kidde 2101017 Worry-Free Sealed Lithium Kitchen Smoke/Co Combo Alarm (Dc)

The Kidde Worry-Free Kitchen Smoke/Carbon Monoxide Alarm offers protection against fire and CO, all in one unit. Alarm comes with a sealed lithium battery for 10 years of continuous protection. That means no batteries to buy. It also comes with both an advanced photoelectric sensor for smoke and an electrochemical sensor for CO. These two features communicate, too, automatically adjusting the sensitivity to better identify real hazards, reducing nuisance alarms when cooking. The alarm is self-activating and comes standard with a Test/Hush button and LED indicator.
