The Consumer Product Safety Commission (CPSC) warned families about GuardianSense and KLTseanife combination smoke and carbon monoxide alarms that fail to sound during a fire.
The CPSC issued the warning on October 29 for model YHW-542COM-R, which was sold on Amazon and eBay. Per the report, the manufacturer and seller have not responded to its request for a recall. Since there is no recall, the notice does not offer a refund or replacement.
What the CPSC Reported
The CPSC lists two reports of the alarms failing to alert people to smoke or fire. As the agency noted, the alarms failed to sound when hazardous smoke and fire were present. This puts people at risk of serious injury or death.
The detectors are electronic combination units that are meant to detect both smoke and carbon monoxide. They are made of white plastic and feature a digital display.
How the Detectors Can Be Identified
Families can check the back of each alarm, where the model number and manufacturer are listed.
- Brand: GuardianSense/KLTseanife
- Model: YHW-542COM-R
- Where sold: Amazon.com and eBay.com
- When sold: September 2025 through June 2026
- Price: Between $18 and $168 for single units and multipacks
- Manufacturer: ShenZhen YuFangWeiShi Technology Co., Ltd., of China
- Seller: Shenzhen Lixiang Xiancai Co., Ltd.
What Families Should Know
The CPSC urged families to stop using the detectors immediately and dispose of them. In earlier warnings about similar alarms, the agency also advised removing the batteries before disposal.
It said to replace them with working smoke alarms and carbon monoxide detectors. Families should not sell or give away the detectors. Anyone who had a safety incident with the product can report it on SaferProducts.gov.
A Second Set of Alarms Was Also Flagged
The CPSC issued a separate warning that same day about JuzhiAnn, Yfwsrecinoe and JAEHSKA combination smoke and carbon monoxide alarms.
The warning covered about 51,825 units of the JZA-540COM model. Those white plastic alarms also have a digital display and were sold as single units or in multipacks. The CPSC said they carry the same hazard.
The seller listed is Shenzhen Laijinhe Trading Co., Ltd., which does business as Yfwsrecinoe US. Both products were made in China.
CPSC’s Reminder for Parents
The agency included general guidance for protecting a home:
- Place smoke alarms and carbon monoxide detectors on each level of the home and outside separate sleeping areas.
- Choose alarms that are battery-operated or have battery backup.
- Test alarms frequently and replace batteries as needed.
- Buy only alarms that meet the UL 2034 and UL 217 safety standards.
These steps apply to any smoke alarm, not only the ones named in the warnings.
Checking a detector’s model number against the agency’s notices can help families spot a problem early. Parents who bought a multipack online in the past year may want to start with the back of each alarm.
