JACKSONVILLE, Fla. – Walter Kidde Portable Equipment Inc. has issued a recall for its Kidde NightHawk talking combo smoke/CO alarm.

Under normal circumstances, smoke alarms produce a chirping sound when it is time to replace the battery. Affected Kidde alarms are said to not indicate end of life or need to change battery, leaving people to believe the alarm is still functioning.

The recall includes model number KN-COSM-IB, which can be found on the back of the device, and manufactured between June 1, 2004 and December 31, 2010.

The alarms are sold at electrical distributors and home centers around the country and on Amazon. They range in price from $40 to $65.

If you find you have one of these alarms, you are advised to replace it immediately. If you have additional questions, you can call the Kidde toll-free number at 855-239-0490 Monday through Friday, 8 a.m. to 5 p.m.
