Abstract
This invention provides fire prevention and detection for heavy-duty and medium-duty commercial and military vehicles by ensuring the engine is automatically and immediately shut down upon the occurrence of a catastrophic event that may lead to a fire. The shutdown is achieved through the isolation of the vehicle batteries and alternator and the disconnecting of those devices from all electrical circuits. Anomalies that cause the shutdown and disconnect include battery and vehicle load currents that are outside a preset range, excessive temperatures, detection of smoke in the drive compartment or sleeper, or detection of a frontal impact accident or vehicle rollover. Once disconnected, the battery contactor must be manually reset in order to restore electrical power to the vehicle.
