The Door interlock device is a system that stops the vehicle when the driver’s door opens.
The system inserts an electrovalve in the parking brake, activating an accoustic alarm and shutting the air supply to the brakes, blocking them, when the driver´s door is opened.
To release the brakes of the vehicle, the door must be closed and the driver must press the button on the panel.
A coded magnetic sensor is used to do the opening detection.
The interlock system also has an input signal to override it in case of emergency.
