ADT Recalls Carbon Monoxide Detectors Due to Failure to Properly Indicate End of Useful Life

Lead / chemical

The hazard

When the CO detectors reach the end of their useful life, they should send a signal to make a sound in the home alarm panel alerting consumers it is time to replace them and a signal to ADT's alarm monitoring center. Some of the detectors were not wired properly to the ADT alarm system, resulting in the sound not going off in the home alarm panel and no signal to the ADT alarm monitoring center at the end of its useful life. Not replacing a CO detector at the end its useful life poses a CO poisoning hazard to consumers.

Incidents reported: None reported.

Consumers should contact ADT immediately for a free inspection of the recalled detectors and, if necessary, a free repair. Consumers should not attempt to disable the recalled detectors. ADT has contacted all customers.
