Kidde Recalls More Than 5 Million Combination Smoke, Carbon Monoxide Alarms
Name of Product: KN-COSM-IBCA Hardwired Combination Smoke/Carbon Monoxide Alarm with battery backup, KN-COSM-ICA Hardwired Combination Smoke/Carbon Monoxide Alarm (without battery backup)
Concern: 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 (or, if you have a model without a battery backup, if power is removed and then restored to the alarm), and the test button is pressed within 10 seconds thereafter, the unit will no longer issue an end of life chirp. Instructions on what to do if you have one of these units are contained within the full recall notice linked below.
