The text below is quoted from the CPSC notice word for word.
- What was recalled
- This recall involves Kidde NightHawk talking combo smoke/CO alarm with model number KN-COSM-IB and manufacture dates between June 1, 2004 and December 31, 2010. The alarms are hard-wired into a home's electric power. The unit has a compartment on the back for the installation of a replaceable 9V backup battery. The alarm is white, round and measures about 5 to 6 inches in diameter. "Kidde" is engraved on the front of the alarm. "Kidde," the model number and manufacture dates are printed on a label on the back on the alarm.
- The hazard
- The alarm can fail to continue to chirp when it reaches its 7-year end of life if the batteries are replaced, leading consumers to believe it is still working. This poses a risk of consumers not being alerted to a fire or CO incident in their home.
- Injuries
- Kidde has received eight reports of incidents with the recalled alarms. No injuries have been reported.
- The remedy
- Consumers should immediately stop using the recalled alarms and contact Kidde directly for a free replacement alarm based on date of manufacture or a discount on a new alarm.
