Apollo America is recalling approximately 50,000 combination smoke and carbon monoxide detectors that may malfunction and not alert consumers to fires or carbon monoxide leaks, as announced by the Consumer Product Safety Commission.

The recalled model 51000-600 detectors from Apollo America present risks of smoke inhalation, carbon monoxide poisoning, or death if the alarms do not sound during emergencies, according to the CPSC.

These white detectors were sold solely by Vivint online and through door-to-door and telephone sales from June to October 2024, priced between $50 to $100. The affected units have “Replace by” dates ranging from June 2034 to October 2034 on the front and feature “Apollo” along with the model number on the back.

No injuries have been reported in connection with the defective detectors.

Vivint is providing free replacement detectors to all known customers. The company advises consumers to continue using the recalled units until replacements arrive, then install the new detectors immediately upon receipt.

After installing replacements, consumers should write “recalled” on the original detector, remove its batteries and dispose of the unit in household garbage. The lithium batteries require special disposal at municipal household hazardous waste collection centers or battery recycling boxes at retail stores, as they can pose fire risks in regular trash.

Consumers can contact Vivint to verify if their detector is included in the recall or check replacement status. Detailed installation instructions are available through the company’s replacement guide.

The CPSC recommends consumers review carbon monoxide poisoning prevention information on the agency’s website.

This recall was announced June 5, 2025.
