Combination smoke and carbon monoxide detectors sold on Amazon, through home-security provider Vivint, and on the HSN shopping network have all been recalled by the U.S. Consumer Product Safety Commission after testing revealed the devices can fail to sound an alarm during a fire. The recalls span multiple brands, hundreds of thousands of units, and sales windows stretching from mid-2024 into spring 2026, raising questions about how so many defective detectors reached consumers through different retail channels.
Repeated failures across brands and retailers
The most recent action targets Treatlife Technology combination smoke and CO detectors, which were sold exclusively on Amazon for approximately $40 between November 2025 and April 2026. The CPSC recall notice warns of a risk of serious injury or death because the units can fail to alert occupants to a fire, undermining the core safety purpose of the devices.
That action follows a pattern. Earlier, Apollo America recalled roughly 50,000 model 51000-600 detectors distributed by Vivint between June and October 2024 for the same hazard: failure to alert consumers to a fire or carbon monoxide leak. According to the CPSC, the Vivint-supplied units could remain silent in conditions where they should alarm, prompting a safety recall that offered free replacements.
Separately, Three61 recalled about 328,000 Samurai Mini Smoke Alarms, model SM1, sold exclusively by HSN. In that case, eight reports of failure to activate had already been filed, though no injuries were reported at the time of the recall. The units, marketed as compact and easy to install, were supposed to provide basic smoke detection but instead introduced uncertainty about whether they would respond in an emergency.
The CPSC also issued a distinct product safety warning, rather than a cooperative recall, directing consumers to immediately stop using detectors manufactured by Shenzhen Lidingfeng Tech. The agency’s own smoke-sensitivity testing found that the model JSN-JY-909COM failed to detect smoke at levels required by industry benchmarks. That warning covered alarms sold under multiple brand names on Amazon and emphasized that the Shenzhen-made detectors did not meet UL 217 sensitivity thresholds.
Common certification gaps or isolated defects
The fact that four separate product lines from unrelated manufacturers all failed the same basic function-detecting smoke and sounding an alarm-invites a harder question: whether the problem sits upstream, in the way these devices are tested and certified before they reach store shelves.
UL 217 is the standard that smoke alarms are generally expected to meet. It specifies how sensitive a detector must be to different types of smoke, how quickly it must respond, and how it should perform under various environmental conditions. Manufacturers typically rely on third-party laboratories to verify that their products conform to this benchmark before applying certification marks and marketing the devices as compliant.
When the CPSC ran its own smoke-chamber tests on the Shenzhen Lidingfeng devices, the agency reported that the JSN-JY-909COM units failed to respond to smoke levels that should have triggered an alarm under UL 217 criteria. In the Treatlife and Apollo America cases, the recalls similarly cited failures to alert consumers to fire or carbon monoxide, suggesting that whatever certification processes were used did not reliably catch performance problems before the products were widely sold.
It remains unclear from the public notices whether the affected devices were ever properly certified to UL 217 or related standards, or whether they bore marks that were used incorrectly. The CPSC documents focus on the hazard and the corrective action-stop using the products, obtain a refund or replacement-rather than detailing the full chain of testing and approval. That lack of transparency makes it difficult for consumers to know whether the breakdown occurred in manufacturing quality control, in third-party testing, or in how retailers vetted the products they chose to stock.
What consumers should do now
For households, the immediate concern is practical: determining whether any of the recalled or warned-about models are installed and, if so, replacing them quickly. The CPSC advises consumers to check the model numbers printed on the back or inside the battery compartment of their alarms and compare them against current recall and warning lists. If a detector matches a recalled Treatlife, Apollo America, Samurai Mini, or Shenzhen Lidingfeng model, it should be removed from service and the manufacturer’s recall instructions followed.
Safety experts also recommend using the test button on each alarm monthly, but they caution that a successful button test does not guarantee full compliance with sensitivity standards. The recent recalls show that a device can power on and beep when prompted yet still fail to detect smoke or carbon monoxide at dangerous levels. As a result, many fire departments and building inspectors encourage consumers to favor well-established brands, ensure that alarms carry recognized certification marks, and replace units every 10 years or sooner if a manufacturer specifies a shorter service life.
For regulators and retailers, the clustering of failures across multiple brands raises pressure to scrutinize smoke and carbon monoxide detectors more closely before they reach customers. That could mean more frequent government spot-testing, tighter documentation requirements for certification, or updated standards that better reflect modern home environments. Until those systemic questions are addressed, the burden remains on consumers to verify their alarms and act quickly when a recall or safety warning is issued.
