What the CPSC says
The CPSC issued a product safety warning on August 20, 2026 covering TJTFJS 2-in-1 carbon monoxide and smoke detectors. According to the agency, the detectors can fail to provide an alert during hazardous smoke and fire conditions.
Recommended consumer action
The CPSC advises consumers to stop using the affected detectors immediately, dispose of them, and install working smoke alarms and carbon monoxide detectors. The agency also says not to sell or give away the affected products.
Why this belongs on a fire-alarm industry site
These are consumer smoke/CO products rather than a commercial addressable fire alarm panel, but life-safety product warnings are worth tracking. Service technicians and inspectors regularly encounter standalone alarms in residential, mixed-use, lodging, and accessory spaces, and customers often ask whether a device seen online is acceptable.
If you encounter an affected product, use the official CPSC notice for identification and consumer instructions. Do not substitute a visual guess for the agency's product information.
