(NBC) — More than 3.5 million combination smoke and carbon monoxide alarms are being recalled in the United States and they may be in your home. The recall involves Kidde Nighthawk talking combo smoke/carbon monoxide alarms manufactured from June 2004 through December 2010.
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. The problem poses a risk of consumers not being alerted to a fire or carbon monoxide incident in their home.
Kidde has received eight reports of incidents. No injuries have been reported. Consumers should contact Kidde directly for a free replacement alarm.
An additional 1.5 million units were sold in Canada.
