More than 3 million smoke/carbon monoxide alarms recalled


NORTHEAST WISCONSIN (WBAY) – About 3.6 million smoke/carbon monoxide detectors are being recalled because the alarm could fail to work.

The recall involves Kidde NightHawk talking combo smoke or carbon monoxide alarms that were sold at electrical distributors, home centers nationwide and online at from June 2004 through December 2010.

The products have the model number KN-COSM-IB.



The U.S. Consumer Product Safety Commission says the alarm can fail to continue to chirp when it reaches its seven-year end of life if the batteries are replaced, leading consumers to believe it is still working. That means there’s a risk that customers would not be alerted to a fire or carbon monoxide incident in their home.

Kidde has received eight reports of incidents with the recalled alarms, but no injuries have been reported.

Anyone who owns this alarm should immediately stop using it and contact Kidde directly at 855-239-0490 or for a free replacement alarm.
