Bpt VA-01 Installation Manual page 26

VA/01 allows a single intercom group.
If you need to add other intercom groups, it is necessary to install a VSE/310 selector downstream from the video distributor for each group. It is not possible
to configure one intercom group with VA/01 and others with VSE/301 at the same time.
