Kidde has announced a recall of 452,000 smoke alarms after finding that they may not go off when there is a fire. A yellow cap was left on during manufacturing and can cover one of the two sensors, making it harder for the alarm to detect smoke.

The recall involves Kidde dual sensor smoke alarms that were sold between September 2016 and January 2018 at The Home Depot, Walmart, Amazon, and more. The Consumer Product Safety Commission has received one report of a yellow protective cap being present, but no incidents or injuries have been reported to date.

The following model numbers and date codes are affected by the recall:

• Model Number: PI2010 (AC/hardwired) Date Code: 2016 Sep. 10 through 2017 Oct. 13

Consumers who own one of these models should remove the alarm from the wall or ceiling and look through the opening on the side of the device for the presence of a yellow cap. It is important that owners do not attempt to take apart the alarm, open the casing, or remove the yellow cap themselves.
