Recall Information Record – Reclia Database

Recall Summary
This recall involves the DeNova Detect brand combination natural gas and carbon monoxide alarms. The recall was initiated by New Cosmos USA Inc., of Lisle, Illinois, and was published on November 14, 2024. The recall number is 25045. The recall was issued due to a failure of the alarms to properly alert consumers to the presence of natural gas and to the risk of carbon monoxide poisoning. No injuries have been reported in connection with this recall.

Affected Products
The recalled product is the DeNova Detect brand combination natural gas and carbon monoxide alarm, model number DD622NCV. The words “DeNova Detect, Natural Gas + Carbon Monoxide” are printed on the front of the alarm. The model number is located on the top side of the alarm. The serial number is on the right side of the alarm. Approximately 26,360 units are affected. The alarms were manufactured in Japan. They were sold at Lowe’s stores nationwide and online at Amazon.com, Lowes.com, and Denovadetect.com from December 2023 through July 2024, with a price range between $90 and $102.

Hazard Information
The hazard associated with this product is that after the alarm has alerted consumers to the presence of natural gas or carbon monoxide, the recalled alarm can go into sleep mode when the alert lasts less than four minutes. During this sleep mode period, the alarms can fail to detect and alert consumers to a new incidence of natural gas or carbon monoxide. This failure to detect and alert poses a risk of carbon monoxide poisoning. No injuries have been reported as of the date of the recall notice.
