NASHVILLE, Tenn. (WTNH) — Check your smoke and carbon monoxide alarms. Kidde NightHawk has recalled about 3.5 million combination alarms due to alarm failure.

According to the U.S. Consumer Product Safety Commission, the alarms with the model number KN-COSM-IB and manufacture dates between June 1, 2004 and Dec. 31, 2010 are involved in the recall.

Once the alarm reaches its seven year end of life, it may not chirp, even if the batteries have been replaced, leading homeowners to think it is still working. This may not alert consumers if there is a fire or carbon monoxide in the home.

Kidde NightHawk has received eight reported incidents with the recalled alarms, none of which resulted in injuries.

If you have this alarm, you should stop using it immediately and contact the company for a free replacement or a discount on a new alarm.
