Kidde Carbon Monoxide & Smoke Detector

The Kidde P3010K-CO is a 10-year, sealed battery, smoke alarm and carbon monoxide alarm the features photoelectric and electrochemical sensing technology and Smart Hush feature. This combination alarm combines the detection capabilities of a photoelectric sensor with that of an electrochemical sensor, which is used 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 one. This constant communication enhances the alarm's overall performance and significantly reduces the potential for a nuisance alarm. At the end of the alarm life, the unit will chirp, indicating the alarm is in need of replacement. The sealed-in lithium battery will power the unit for the entirety of its 10 year life, eliminating the need for battery replacement and ends worry of unauthorized battery removal.
