The detectors can fail to alert consumers to the presence of smoke. Smoke sensitivity testing by CPSC found that they fail UL 217, the voluntary safety standard for smoke alarms, and may not alert consumers in the event of a house fire.

Washington, D.C. -- The U.S. Consumer Product Safety Commission (CPSC) is warning consumers about the risk of serious injury or death associated with defective smoke and carbon monoxide detectors manufactured by Shenzhen Lidingfeng Tech. and sold under multiple brand names, including PetUlove, ORIKLON, SENCKIT, Kingebai, Gaoducash, LDASEC, and AMS. The defective detectors have model number JSN-JY-909COM.

Smoke sensitivity testing by CPSC found that they fail UL 217, the voluntary safety standard for smoke alarms, and may not alert consumers in the event of a house fire. In typical residential fire scenarios, there may be as little as three minutes to escape after a smoke alarm sounds before the conditions in the home become incapacitating or deadly. An estimated 2,440 people in the United States die every year from residential structure fires. Furthermore, the risk of dying in a fire is twice as high in homes without a working smoke alarm, as compared to homes with smoke alarms.Shenzhen Lidingfeng Tech. Co., Ltd., of China has been unresponsive to CPSC’s request to recall the products.The combination detectors are made of white plastic and measure about 4 x 1.5 x 4 inches, featuring a digital display. “CO & Smoke Alarm,” the model number, and “Shenzhen Lidingfeng Technology Co Ltd” are printed on a white sticker on the detectors. The combination detectors are advertised to detect dangerous levels of carbon monoxide and smoke, and alert with a flashing red LED and a loud alarm pattern.
