Abstract
A heat alarm for an electric panel cabinet that mounts a temperature sensor within the enclosed area defined by the cabinet and sounds an alarm if the temperature within the cabinet exceeds an upper temperature limit. The heat alarm includes a microprocessor that operates an audible alarm upon sensing an overheat condition. After operating the audible alarm for a continuous period of time, the microprocessor operates the audio alarm in a series of sound pulses separated by a silence interval. The silence interval increases as the continuous period during which the temperature in the electric panel exceeds the upper temperature limit increases. The heat alarm includes a manually operable alarm override device that can be depressed to deactivate the audible alarm for an override period to allow the home/business owner to address the overheat condition within the electric panel cabinet, without the distraction of the audible alarm.
