Kidde KN-COSM-XTR-BA Intelligent Alarm, Battery Operated Combination Smoke & Carbon Monoxide Alarm

The Kidde KN-COSM-XTR-BA uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you from carbon monoxide and dramatically reduce the chance of nuisance alarms. In addition, the Intelligent Alarm contains a voice warning that clearly states the present danger - smoke or carbon monoxide - and announces "FIRE!" or "WARNING! CARBON MONOXIDE!" The Intelligent Alarm combines the detection capabilities of an ionization smoke sensor - which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires - with that of an electrochemical sensor, which is used to detect CO.

Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. 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 in all fires, and significantly reduces the potential for a nuisance alarm.
