美国消费品安全委员会（CPSC）发出警告，要求消费者立即停用 GuardianSense 与 KLTseanife 品牌的烟雾与一氧化碳组合探测器，型号为 YHW-542COM-R。这款探测器在有危险烟雾与火焰时不能发出警报，可能造成严重伤害或死亡。
委员会已收到两起这款报警器失灵的报告，两起都是在有烟雾或火焰在场时报警器没有报警。这款产品为白色塑料外壳、带数字显示屏，型号 YHW-542COM-R 与制造商名称印在产品背面。
这款探测器以单只装或多只装在亚马逊（Amazon）与 eBay 上销售，销售期为 2025 年 9 月至 2026 年 6 月，售价约 18 至 168 美元，产品由中国制造。制造商 ShenZhen YuFangWeiShi Technology Co LTD. 与销售商 Shenzhen Lixiang Xiancai Co., Ltd. 对消费品安全委员会（CPSC）的召回要求均没有回应。
委员会敦促消费者立即停用这款探测器、将其丢弃，并换装能正常工作的烟雾报警器与一氧化碳探测器；这款危险产品不得转卖、也不得赠送他人。
委员会同时提醒，住家每一层楼以及每个独立睡眠区之外都应安装烟雾报警器与一氧化碳探测器，并只选购符合 UL 2034 与 UL 217 安全标准的产品。消费者可查阅消费品安全委员会（CPSC）这条警告的原文，按产品背面的型号核对自家探测器。
CPSC Warns Consumers to Stop Using GuardianSense and KLTseanife Combination Detectors Immediately: Two Reports of Alarms Failing in Smoke and Fire
The U.S. Consumer Product Safety Commission (CPSC) is warning consumers to stop using GuardianSense and KLTseanife brand combination smoke and carbon monoxide detectors, model YHW-542COM-R, immediately. The detectors fail to alarm in the presence of hazardous smoke and fire, posing a risk of serious injury or death from smoke and fire hazards.
CPSC is aware of two reports of the alarms failing to alert in the presence of smoke or fire. The detectors are white plastic with a digital display, and the model number YHW-542COM-R and the manufacturer are listed on the back of the product.
The detectors were sold on Amazon.com and eBay.com from September 2025 through June 2026, in single units and multipacks, for between $18 and $168, and were manufactured in China. The manufacturer, ShenZhen YuFangWeiShi Technology Co LTD., and the seller, Shenzhen Lixiang Xiancai Co., Ltd., have both been unresponsive to CPSC's request to recall the detectors.
CPSC urges consumers to stop using the detectors immediately, dispose of them and install working smoke alarms and carbon monoxide detectors. The hazardous detectors should not be sold or given away.
CPSC also advises installing smoke alarms and CO detectors on each level of the home and outside separate sleeping areas, and buying only alarms that meet the UL 2034 and UL 217 safety standards. Consumers can check the model details in the CPSC warning notice.
