Kidde Recalls More Than 5 Million Combination Smoke, Carbon Monoxide Alarms

Kidde is recalling 3.6 million smoke alarms in the United States, and another 1.5 mllion in Canada, the company and the U.S. Consumer Product Safety Commission said on Thursday.

The recall involves the Kidde NightHawk talking combo smoke/carbon monoxide alarm with model number KN-COSM-IB and manufacture dates between June 1, 2004 and Dec. 31, 2010. 

The alarm can fail to continue to chirp when it reaches its seven year end-of-life, even if the batteries are replaced, leading consumers to believe it is still working. Kidde has received eight reports of incidents with the recalled alarms; no injuries have been reported.

Consumers should immediately stop using the recalled alarms and contact Kidde   for a free replacement alarm.
