The system (30) has a master actuator (50) cooperating with a covered door leaf (10), and slave actuator (60) cooperating with a covering door leaf (20), where a remote control device (40) controls the master actuator. A unidirectional communication unit e.g. electric cable, allows transmission of reference signals from the control device to the master actuator, or from the control device to the master and slave actuators, or from the master actuator to the slave actuator, without confirmation of reception of signals in return. An independent claim is also included for an installation for controlling opening and closing of door leaves of a gate, a main door, and a window. |
