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.

Consumers have been instructed to stop using the affected detectors and can contact Kidde Inc. for a replacement or discount on a new detector.
