INSTALLATION
INSTRUCTIONS
FLOOR
CODER/DECODER CD/204
The unit enables the C/200 hand-
set, the VM/200 - VM/203 series
monitors and VMF/200 - VMF/203
monitors to be installed in coded
call installations.
The CD/204 unit enables 4 recei-
vers to be connected and is the-
refore an excellent solution for
encoding/decoding on the floor.
Only one receiver plus an RC/200
call repeater can be connected to
a CD/204 output.
Owing to its small size, the unit
can be inserted in a regular con-
nector box (90 x 90 x 40 mm), or
can be installed on a DIN guide
(EN 50022) (fig. 3).

Programming
- Power up the unit and remove
the
SW
software programming
jumper (fig. 1).
- Send the code relating to the
user connected to output 1 via the
coded call entry panel, or the
VPD/100 porter’s switchboard.
If the programming jumper is
inserted at this point, the codes
following the one transmitted are
assigned to the other 3 users in
sequence.
If, on the other hand, the installer
wishes to assign each user a non-
progressive code, send the code
relating to the user connected to
output 2, followed by the code
relating to the user connected to
output 3, and lastly the code rela-
ting to the user connected to out-
put 4.
- Insert the
SW
jumper.
N.B. If the programming is carried
out via the porter’s switchboard,
the acknowledgement of the com-
pleted programming is given by the
code sent to the extension appea-
ring on the display (PORTER
CALL).
The unit generates two types of
call note:
a:
continuous bi-tonal note lasting
at least one second;
b:
rings lasting 0.6 seconds repea-
ted every 2 seconds, for the dura-
tion of the call, with a minimum of
2 rings.
The unit is factory set with the note
type
a
for calls from the entry
panel, and with note type
b
for
calls from the porter’s switchboard
(the connection must be made to
terminal
N2
before note type
b
can
be obtained).
The type of note can be inverted
by sending the code
80160
(block
code) or
13120
(progressive-
mode code) to the unit.
In order to reset the initial condi-
tions, send the code
80161
(block
code) or
13121
(progressive-
mode code) to the unit.
The modification of the call note
must be carried out when in pro-
gramming mode (with the
SW
jumper disconnected).
Technical features
• Supply voltage: 10 ÷ 18 VDC.
• Current demand: 8mA (110 mA
during call).
• Maximum number of CD/204
units which can be connected
in a block: 200.
• Working temperature range:
from 0°C to +35°C.
• Dimensions: 60 x 44 x 16 mm.
