The KIDDE Worry Free Smoke and Carbon Monoxide Alarm features a voice warning system and is powered by a sealed lithium battery. Its voice warning system features photoelectric and electrochemical sensing technology with a Smart Hush feature. This combination alarm combines the detection capabilities of a photoelectric sensor with an electrochemical sensor in order to detect CO. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false alarm.
