The dead-man system is designed to caution and alert the locomotive drivers .It is equipped with a caution and alert the locomotive drivers. This system has two timers which operate at 74-volt locomotive voltages. When the locomotive moves, the driver must push the pedal repetitively in one minute intervals to inform the system that he is not incapacitated and it is safe to proceed. Otherwise an alarm sounds and after passing 5 seconds the train stops.In the new models, the event recorder has been assimilated with the dead-man system, and the extractable information is saved in memory. It has several inputs and outputs that communicate with various parts of the locomotive, such as the dynamic lever and regulators. According to this information, signals are sent to other parts such as automatic train stop, alarms, etc.
