消费品安全委员会警告：两款在亚马逊和eBay出售的烟雾一氧化碳复合报警器可能失灵，应立即停用丢弃
美国消费品安全委员会（CPSC）10月29日连发两则警告，提醒消费者立即停用两款在亚马逊（Amazon）和eBay上出售的烟雾与一氧化碳复合报警器：这两款产品在有烟雾和火焰时可能根本不报警，存在严重伤亡风险。
第一款是型号JZA-540COM的复合报警器，以JuzhiAnn、Yfwsrecinoe和JAEHSKA三个品牌名出售，2023年11月至2026年10月间共售出约51,825只，售价11至107美元，生产方为中国深圳市莱瑾合贸易有限公司（以Yfwsrecinoe US名义经营）。CPSC已收到7起该报警器在烟火面前没有报警的报告。第二款是GuardianSense和KLTseanife品牌的YHW-542COM-R型，2025年9月至2026年6月出售，售价18至168美元，CPSC收到2起失灵报告。两款都是白色塑料外壳、带数字显示屏的复合报警器，有单只装和多只装。
CPSC说，两家销售方对委员会的召回要求都没有回应，因此这次发布的是安全警告而非正式召回，也没有退款或更换安排。委员会要求消费者立即停用并丢弃这些报警器，不要转卖或送人，并马上换装能正常工作的烟雾和一氧化碳报警器。
CPSC提醒，选购报警器时只认符合UL 217（烟雾报警）和UL 2034（一氧化碳报警）安全标准的产品；报警器应装在住宅每一层和每个卧室区域外，并使用电池或带电池备电。家中报警器若曾失灵，可到SaferProducts.gov报告。
CPSC Warns: Two Combination Smoke and CO Alarms Sold on Amazon and eBay May Fail to Sound
The U.S. Consumer Product Safety Commission (CPSC) issued two warnings on October 29 urging consumers to immediately stop using two combination smoke and carbon monoxide alarms sold on Amazon and eBay, saying the devices can fail to sound in the presence of smoke and fire and pose a risk of serious injury or death.
The first warning covers model JZA-540COM alarms sold under the JuzhiAnn, Yfwsrecinoe and JAEHSKA brand names. About 51,825 units were sold from November 2023 through October 2026 for $11 to $107. The alarms were made by Shenzhen Laijinhe Trading Co., Ltd. of China, doing business as Yfwsrecinoe US, and CPSC is aware of seven reports of the alarms failing to alert in the presence of smoke or fire. The second warning covers GuardianSense and KLTseanife model YHW-542COM-R alarms sold from September 2025 through June 2026 for $18 to $168, with two failure reports. Both models are white plastic combination alarms with digital displays, sold singly and in multipacks.
CPSC said the sellers have been unresponsive to its requests to recall the products, so the agency issued warnings rather than recalls, and there is no refund or replacement program. Consumers should stop using the alarms immediately, dispose of them, and not sell or give them away, then install working smoke alarms and carbon monoxide detectors.
When buying replacements, CPSC says to choose only alarms that meet the UL 217 standard for smoke alarms and the UL 2034 standard for carbon monoxide alarms. Alarms should be installed on every level of the home and outside separate sleeping areas, and should be battery operated or have battery backup. Consumers who have experienced an alarm failure can report it at SaferProducts.gov.
