INTERCOMMUNICATION MODE – SW3.1
This switch establishes the intercommunication mode: in OFF position (default) intercommunication is between units in the same
apartment (same addresses but different extension); in ON position the intercommunication is between units in different apart-
ments (different addresses).
On installations where there are more than one intercom/videophone in the same apartment and intercommunication between different
apartments is required, only one intercom/videophone may be set with this function (SW3.1=ON, SW3.2=OFF, SW3.3=OFF). The other inter-
com/videophones in the apartment must be set for local intercommunication with extension addresses “2-4” (slaves). From the inter-
com/videophone set for intercommunication with other apartments it will be not possible to intercommunicate within the apartment but slave
extensions 2-4 will be able to intercommunicate with each other.
EXTENSION NO – SW3.2..3
If the intercommunication between apartments is enabled (switch 1 of SW3 = ON) leave these two switches in default position (both to OFF). Otherwise,
if the intercommunication is between the same apartment (switch 1 of SW3 = OFF), set the extension addresses starting always from 1. During the ex-
ternal call, all video monitors in the same flat will ring but the video will be shown only from the videmononitor with extension address 1.

SLAVE MODE - SW3.4
This set up concerns the answering mode of the video monitor when there is more than one unit (max 4) in the same apartment.
OFF (default) = during a call, only the video monitor with extension 1 (master) will show the video. ON = the video monitor will be
switched on independently of the extension address: in this case the video monitor must be supplied locally using a power sup-
ply Art.2321 and connecting respectively BUS+ to terminal 14 and BUS- to terminal 11 of the pcb connection board provided
with the Art.5980 (the local power supply is required for each black & white slave videophone or starting from the third slave vid-
eophone when are used all colour videophones). If you set ON this switch for one slave videophone, you must set ON the same switch also for
the relevant master videophone.
