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.
The KIDDE Carbon Monoxide Alarm's sealed in lithium battery powers the unit for the entirety of its 10-year life, eliminating the need for battery replacement and worry about unauthorized battery removal. The alarm provides continuous protection from smoke and carbon monoxide, even during power outages. It will also automatically activate when it is attached to the mounting bracket with no pull-tabs or switches necessary.
