Abstract
A smoke alarm system for providing interconnect supervision between detectors includes smoke detectors configured so that an interconnect line extends between each of the smoke detectors. In one embodiment using a wired connection, each of the smoke detectors includes an interconnect input and an interconnect output for connecting the smoke detectors into a loop configuration. Similarly, the system may also operate to provide interconnect supervision in a wireless manner such that each of the smoke detectors is polled on a periodic basis. Thus, the smoke alarm system uses interconnect supervision for alerting other detectors of a smoke and/or carbon monoxide alarm as well as altering other detectors to a fault condition.
