Kidde is recalling the NightHawk talking combo smoke/CO Alarm – Model Numbers – KN-COSM-IBCA and KN-COSM-ICA with manufacture dates between June 1, 2004 and March 2011. The alarms are hard-wired into a home’s electric power.
The alarm can fail to continue to chirp when it reaches its seven year end of life if the batteries are replaced, or for the model without a battery backup, if power is removed and then restored to the alarm. This could lead consumers to believe it is still working, which poses a risk to consumers not being alerted to a fire or carbon monoxide incident in their home.
Consumers should immediately stop using the recalled alarms and contact Kidde directly for a free replacement alarm based on date of manufacture or a discount on a new alarm.
