Name of product:
CO 1224T Carbon Monoxide (CO) detectors
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.
