      Intelligent combination alarm offers you and your family protection from fire and carbon monoxide. The intelligent combination alarm uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you and your family from carbon monoxide. Voice warning alerts you to the type of danger present. 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 electro-chemical sensor, which is used to detect CO. 10 Year Warranty.

      First Installed this Kiddie M/N# KN-COSM-B combo smoke/CO alarm in October of 2004. It worked fine the entire time it was installed. it uses (3) AA batteries not the typical 9V. The voice prompts (when testing and low battery) are clear and loud enough to hear easily. On the negative side, It hit it's built in expiration date the night before last at 3AM. (7 years and 1 month after the initial installation) Would be nice if they could build it to last 10 years - but then i guess they'd sell less of them because I plan to buy another.. Excerpt from the owners manual about built-in end-of-life countdown timer included below... (from page 5) ? After seven (7) years of cumulative power up, this unit will ?chirp? every 30 seconds. This is an "operational end of life" feature which will indicate that it is time to replace the alarm.
