Kidde has initiated a recall of their NightHawk combination smoke/carbon monoxide detectors on November 10th. The problem is the unit can fail to chirp when it reaches its 7-year end of life if the batteries are replaced, and lead users to believe it is still working properly. This obviously poses a risk of occupants not being alerted in case of a fire or CO incident in their home.
These units were sold by electrical distributors and home centers such as Home Depot, as well as online at Amazon.com from June, 2004 until December, 2010 for $40 to $65. Replacement units can be provided by Kidde by contacting Kidde directly at 1 (855) 239-0490. Free replacements may be provided based on the date of manufacture, or a discount will be provided on a new alarm. The model number subject to his notice is KN-COSM-IB. The units are white in color, approximately 5 to 6 inches round.
