ABSTRACT:
An interface circuit and method for use in interconnected hazardous condition detectors is provided. This circuit and method prioritizes the various hazardous condition alarms to ensure that only the highest priority or greatest threat alarm is sounded when such a condition is detected. In this way a lower priority alarm that may be sounding will be switched to a higher priority alarm so that all interconnected detectors that have the capability will sound the higher priority alarm. This will reduce occupant confusion during a hazardous condition. The circuit and method also provides the ability to silence all interconnected detectors except for those sensing the hazardous condition to allow the occupant to locate the triggering alarm, and there for the location of the sensed hazardous condition.
