When one of the doors is opened, the indicator light of the other door does not light, notifying that the door cannot be opened. Electromagnetic lock action realizes interlocking. When the door is closed, the electromagnetic lock of the other door starts to work, and the indicator light will illuminate, indicating that the other door can be opened.
