The PETRICOR and WJZTEK models feature a label on the back which lists the model number. The PETRICOR and VARWANEO models feature a digital display. The combination detectors are made of white plastic, with approximate dimensions of 4 x 1.5 x 4 inches. Smoke sensitivity tests performed on the PETRICOR, VARWANEO, and WJZTEK detectors by CPSC found that they failed to alert when exposed to pre-determined concentrations of smoke, in violation of UL 217, a voluntary safety standard. If a combination smoke and CO detector that does not alert to the presence of an elevated level of carbon monoxide or smoke is installed in a home, and carbon monoxide or smoke enters the home, the consumer will not be warned of these harmful conditions, making injury or death very likely. Furthermore, the risk of dying in a fire is twice as high in homes without a working smoke alarm (1.18 per 1,000), as compared to homes with smoke alarms (0.53 per 1,000).” More than 2,390 people in the United States die every year from residential structure fires. In typical residential fire scenarios, there may be as little as one or two minutes to escape after the smoke alarm sounds before the conditions in the home become incapacitating or deadly. Most fatalities in residential fires are due to smoke inhalation, rather than heat and flames. ![]() The detectors can fail to alert consumers to the presence of hazardous smoke. ![]() Consumer Product Safety Commission (CPSC) is warning consumers about the risk of smoke inhalation associated with the use of PETRICOR, VARWANEO, and WJZTEK combination smoke and carbon monoxide (CO) detectors. ![]()
