Kidde is recalling 3.6 million smoke alarms in the United States.
The recall involves the Kidde NightHawk talking combo smoke/carbon monoxide alarm with model number KN-COSM-IB and manufacture dates between June 1, 2004 and Dec. 31, 2010.
According to the company, when the alarm reaches the end of its useful life, it issues an end of life chirp every thirty seconds. If the battery is replaced when the unit is at its end of life, and the test button is pressed within 10 seconds thereafter, the unit will no longer issue an end of life chirp.
