ESVK/6388 Series - Installation handbook
SLAVE MODE - SW2.4
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 sup-
plied 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.
