Kidde Nighthawk combo smoke and CO alarm recall: Here’s what you need to know


In what can be deemed as one of the largest recalls for smoke and CO alarms, Kidde has recalled two of its combo smoke and CO alarms – KN-COSM-IBCA and KN-COSM-ICA – across Canada.

According to the company as many as 1.5 million of these combo alarms manufactured between June 2004 and March 2011 have been sold across Canada and users have been asked to stop using them immediately and contact Kidde directly.

Both the smoke/CO combo alarm fail to continue to chirp when they reaches the seven year end of life if the batteries are replaced or, for the model without a battery backup, if power is removed and then restored to the alarm, the company revealed in a press note. According to Kidde this could lead consumers to believe it is still working, which poses a risk to consumers not being alerted to a fire or carbon monoxide incident in their home.

According to Kidde, people in Canada should check their alarms and see whether it is either of the two models affected by the recall. If that’s the case, customers should stop using them immediately and have them replaced at the earliest to avoid any risk of any untoward incident. Kidde will either replace them or offer a discount on new alarms.

Kidde has acknowledged that it is aware of eight incidents related to failures of these alarms, no injuries or fatalities have been reported.

Thunder Bay Fire Rescue has also issued a warning of its own wherein it has asked homeowners and tenants to check the devices in their homes and if they find either of these two installed, they should contact Kidde Canada directly and have them replaced. The combination alarms are hard-wired into the home’s electrical power and have a compartment on the back where homeowners can install a replaceable 9V backup battery.
