EXTENSION NO – SW.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
SW3.2..3
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
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 =
SW3.4 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 supply Art. 2321 and connecting respectively BUS+ to terminal +VAUX 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
(intercoms, videophones or video monitors) in a parallel con-
nection (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 disabled. In case of units of dif-
ferent 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.
