Notes
The audio control device is intended to be installed in the sub-distribution. If this is not possible, use a common surface-mounted distributor.
This component enables door communication systems with up to 70 devices to be established (e.g. 1 x built-in loudspeaker, 5 x add-on modules for built-in loudspeakers, 68 x surface-mounted home stations).
