This recall involves Kidde branded AC/DC powered residential smoke alarms and combination smoke/CO alarms, models KN-COSM-IBACA, i12010S-CO-CA and i12010S-CA.
These alarms are white, round, and approximately 5 to 6 inches in diameter, with an engraved Kidde logo on the front. They are AC/DC powered and capable of hardwired interconnect.
Labels indicating the model number and date code are located on the back of the device. The date code consists of the year of manufacture, the month of manufacture and the day of manufacture in the YYYY Month XX format.
Should a power outage occur at the same second that the device is performing a once-per-minute sensor health check, the device may go into a “latched” mode, causing it not to alarm in the presence of smoke and/or carbon monoxide. An affected device will sound if it receives a signal from an alarm in the same interconnected system. Once power is restored, a latched device will sound an alarm regardless of the presence of smoke and/or carbon monoxide.
Neither Kidde nor Health Canada have received any reports of consumer incidents or injuries related to the use of these products. Kidde discovered the issue during an internal quality check.
