The system is designed to generate an alarm with a micom according to the signal of a sensor for sensing the flow of electrons dischaged with the electric device on during locking a door by connecting a door locking device with a battery main switch. The door locking device includes the sensor for sensing discharge of the current from the battery during locking the door and the micom for indicating generation of the alarm upon receiving the signal of the sensor.
