The Oregon State Fire Marshall Tuesday released more information about that Kiddie Smoke Detector Recall. Here's some important information about what to look for, and what to do if you have one of the units:

"Kidde issued a recall of 452,000 dual sensor (photoelectric and ionization) smoke alarms sold in the United States. The smoke alarms have the model numbers PI2010 (AC/hardwired) and PI9010 (DC/battery powered). "KIDDE" is printed on the front center of the smoke alarm. The model number and date code are printed on the back of the alarm.

Kidde states that a yellow protective cap in limited instances may have been left on one of the two smoke sensors during the manufacturing process, which could compromise the smoke alarms' ability to detect smoke.

Consumers should remove the alarm from the wall/ceiling and visually inspect it through the opening on the side of the alarm for the presence of a yellow cap. Consumers should not attempt to take apart the alarm, open the casing, or otherwise remove the cap themselves. If the yellow cap is present, the consumer should immediately contact Kidde to receive instructions and request a free replacement alarm. They should remove the recalled smoke alarm ONLY AFTER they receive and install the replacement alarm. If no yellow cap is present, consumers should reinstall the smoke alarm and no further action is needed.

Alarms were sold at Menards, The Home Depot, Walmart and other department, home, and hardware stores nationwide and online at Amazon.com, ShopKidde.com, and other websites from September 2016 through January 2018 for between $20 and $40."
