Abstract
A combination appliance door ajar, occupant emergency and abnormal temperature condition alarm system, in a single unit utilizing three visual indicators, one for each of the emergency conditions, and an audio alarm with multi-tone operation, for each of the emergency conditions. The alarm system incorporates a first light indicator and audio alarm that are triggered in response to a door ajar condition. The time period before the alarm is triggered may be adjusted by means of timer circuitry. The alarm system also incorporates a manually operated switch installed on the interior of the appliance that allows an occupant of the appliance to indicate an emergency condition that requires outside assistance. The occupant emergency system uses a visual indicator and an audible alarm signal that are distinctive from those used for the door ajar system. The alarm system further incorporates a temperature sensor installed on the interior of the appliance for conveying the existence of an emergency temperature condition. The temperature alarm system uses a visual indicator and an audible alarm signal that are distinct from those used for the door ajar and occupant help systems.
