INTERCOMMUNICATION MODE – SW3.1
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 apartments (different addresses).
On installations where there are more than one intercom/videophone in the same apartment and intercommunication between dif-
ferent apartments is required, only one intercom/videophone may be set with this function (SW3.1=ON, SW3.2=OFF, SW3.3=OFF).
The other intercom/videophones in the apartment must be set for local intercommunication with extension addresses “2-4” (slaves).
From the intercom/videophone set for intercommunication with other apartments it will not be possible to intercommunicate with-
in the apartment but slave extensions 2-4 will be able to intercommunicate with each other within the apartment.
EXTENSION NO – SW.2..3
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 inter-
communication is between the same apartment (switch 1 of SW3 = OFF), set the
extension addresses starting always from 1. During the external call, all video monitors in the same
flat will ring but the video will be shown only from the videophone with extension address 1.
SLAVE MODE - SW3.4
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 teVAUX and BUS- to terminal GND on the connection terminals (the local power
supply is required for each black & white slave videophone or starting from the third slave videophone when they are all colour videophones).
If you set for one slave videophone, you must set ON the same switch also for the relevant master videophone.
BUS LINE TERMINATION
The factory pre-set is termination enabled. In case of more units (in-
tercoms, videophones or video monitors) in a parallel connection (bus
wires are connected to the terminals of the first unit then from this to
the second and so on up to 4 units max) Termination must be enabled
only for the last unit in the chain while on all other units must be dis-
abled. In case of units of different type, videophones, video monitor,
hands free or standard intercoms etc. remains fixed the rule that the bus termination must be enabled only on the last unit in order of connection.
