Multi machine synchronous control mode

This scheme is used for the window type with large single bolt area and heavy window. In order to ensure the sealing performance of the window sash when it is opened and closed, two or more window openers are installed to synchronously perform the opening and closing action. The built-in synchronization modules in the window opener studio detect each other's running speed and make adjustments to ensure the synchronous operation of multiple machines. Four machines can be synchronized at most without additional synchronizer. The 24V power connected to the switch is provided by the fire linkage control box or intelligent ventilation control box.
