4. Jumpers to defi ne the type of power supply
to the device.
Power from Bus line
(DEFAULT)
Power from local external power
supply
5. +/- 24V terminals: external local power supply
terminals.
In one-household systems with
only one video door phone, the Call
Forwarding Device can be powered
directly off the bus line. In two-
household systems ref. 1722/86 it
is necessary to use an adapter ref.
1083/24.
6. Jumper Z: line termination setting.
Line termination must be activated on a
device connected at the end of a line without
a new section restarting from the LINE OUT
terminals.
Termination on
(DEFAULT)
Termination off
7. LINE IN, LINE OUT terminals: connection to
the system BUS.
