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.
Certain 2Voice system confi gurations allow the
Call Forwarding Device to be powered directly
from the BUS line of the system without using
a local power supply ref. 1083/24; a few limit
examples are listed in the following table:

(*) Any excess devices must be powered off local
power supplies ref. 1083/24
It is possible, however, to calculate the exact
number of Call Forwarding Devices (without
power supply) that can be arranged within the
system, knowing the type and the number of
indoor stations that you wish to use:
1. In the case of a system with 2Voice
cable or HVV05-F cable 1 mm
or single wire, 1 mm

2. In the case of a system with Cat5 cable
or telephone wire pair with Ø 0.6 mm
(AWG22)
CFSAmax = [127 – PI1 – (2*PI2) – CF] / 30
Where:
CFSA: is the result that expresses the
maximum number (rounded down) of
Call Forwarding Devices without power
supply that can be powered off the
system BUS.
PI1: number of indoor stations (video door
phones/door phones) mod. Miro or
video door phones mod. Aiko/Folio
present in the system.
PI2:
number of indoor stations (video door
phones mod. Modo or PABX interfaces)
present in the system.
CF: Number of Call Forwarding Devices
present in the system.
6. LINE IN, LINE OUT terminals: connection to
the system bus.
7. 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
8. Dip switch CODE: they defi ne the number of
the apartment in the column:
no. 1: do not move, it should remain set
•
to OFF (if set to ON and then back to OFF, it
will return the column address to its default
value);
• no. 2 to 8: they defi ne the apartment number
in the column
For no. 2 to 8 dip-switch settings, refer
to the System 2Voice manual.
