As stated by the U.S. Consumer Product Safety Commission, Walter Kidde Portable Equipment Inc. has recalled millions of combination smoke/carbon monoxide alarms as result of alarms failing to chirp after they have reached their seven-year-end-of-life, even if batteries have been replaced. Under these circumstances, the consumer could falsely believe the alarm to still be working, which poses a risk of undetected smoke or carbon monoxide.
The detector involved is called the “Kidde NightHawk Combination Smoke/CO Alarm”.
Eight reports of incidents involving the alarms have been issued; no injuries have been reported.
3.6 million detectors have been sold in addition to 1.5 million sold in Canada. Devices sold at electrical distributors and home centers nationwide as well as online on Amazon.com for $40-$65 from June 2004 to December 2010.
The devices are manufactured in China and are imported by Walter Kidde Portable Equipment Inc. of Mebane, N.C. .
Consumers have been instructed to stop using the affected detectors and can contact Kidde Inc. for a replacement or discount on a new detector.
The following information is provided by the U.S. CPSC:
The model number for the detectors involved is KN-COSM-IB. This number can be found along with the manufacture dates printed on a label on the back of the detector.
Each unit has a compartment on the back for the installation of a replaceable 9V backup battery.
The alarm is white, round, and measures about 5-6 inches in diameter.
“Kidde” is engraved on the front and back of each device.
