Complainant purchased newly constructed home in October 2014 and in June 2015 his 8 hardwired smoke detectors started falsely activating during the night and day. He contacted Kidde customer support and they advised him to trouble shoot them by disconnecting them from the hard wire and running them on battery power. After conducting the test, he found that 2 out of the 8 units were defective. He contacted Kidde customer support again and they sent him 2 new detectors. He asked if he needed to send them back to be examined and they told him no and instructed him to throw them away.

As a Senior Fire Investigator for the Maine State Fire Marshal's Office, I believe that 2 out of 8 detectors being defective is unacceptable, and that Kidde should be examining defective smoke detectors in order to identify the cause of the failure. It is my experience that faulty detectors can mean the difference of life and death in a fire event, and nuisance alarms cause people to not use their smoke detectors. The complainant is the Town Fire Chief and had thrown the detectors away before informing me of the issue.

Comment from UTC Fire & Security 8/14/2015
Thank you for submitting an incident report on

From the product information you submitted Kidde cannot identify the model and date of manufacture of the smoke alarms referenced in your submission.

However, please be advised that Kidde has in conjunction with the US Consumer Product Safety Commission issued a voluntary recall of Kidde residential smoke alarm model i12010S with manufacture dates between December 18, 2013 and May 13, 2014, combination smoke/CO alarm i12010SCO with manufacture dates between December 30, 2013 and May 13, 2014, and combination smoke/CO alarm model KN-COSM-IBA with manufacture date between October 22, 2013 and May 13, 2014. They are hard-wired into a home’s electric power. The i12010S and i12010SCO come with sealed 10 year batteries inside. The KN-COSM-IBA model has a compartment on the front for installation of replaceable AA backup batteries.

The safety issue identified by Kidde was the alarms could fail to alert consumers of a fire or a CO incident in the event of a power outage. While power remains out, an affected device will sound if it receives a signal from an alarm in the same interconnected system. Once power is restored, an affected device will sound an alarm regardless of the presence of smoke and/or carbon monoxide. A copy of the Recall Alert can be found by clicking the link located in the Safety Product Notice of the front page of or on the CPSC’s website. The Recall Alert will help you identify if an alarm is within the scope of this recall.

As part of its corrective action plan for the recall of these alarms, Kidde maintains a dedicated recall hot line which is available Monday through Fridays 8AM to 5PM. A dedicated recall hotline assistant can also assist with determining whether your alarm is within the scope of this recall. If you alarm is determined to be in the scope, you will be sent a replacement alarm, and instructed to dispose of the old alarm upon installation of the replacement alarm.

Consumers can call Kidde’s established recall hotline at (844) 553-9011for further assistance.
