A recall has been issued by a major smoke and carbon monoxide manufacturer that affects over a million consumers in the U.S. and Canada.  Kidde, which has been a pioneer in the industry since 1917, has issued a recall for three models of hardwired smoke and carbon monoxide detectors.

Smoke alarm model i12010S and combination smoke/carbon monoxide (CO) alarms models KN-COSM-IBA and i12010SCO were recalled because they could fail to alert consumers of a fire or carbon monoxide leak if there is a power outage.  The recalled alarms were sold at CED, City Electric Supply, HD Supply, Home Depot, Menards, Amazon.com and other electronics retailers.

During a power failure, the devices will go off if it receives a trigger signal from another interconnected alarm.  Upon power restoration, affected detectors will sound an alarm whether or not smoke or carbon monoxide is detected.

The Kidde website is instructing consumers to keep their existing warning systems in place until a replacement can be obtained and installed.  This recall does not include alarms purchased prior to December 2013, and battery powered Kidde smoke and carbon monoxide detectors.
