DEVICE
Type 6949

TECHNICAL SPECIFICATIONS

Type 6949 is a programmable
multifunction device for use with
DIGIBUS systems. The device
solves specific requirements in
DIGIBUS systems.

Type 6949 can be used as:

- Converter of codes from 4 to 8 digits and vice versa. Type
6949 enables the combination of interphones and monitors with
4-digit encoding/decoding with entrance panels and switch­boards with 8-digit encoding/decoding. Type 6949 converts the
call codes and the commands F1, F2 and door lock release, from
4 to 8 digits and vice versa by adding or removing the 4 digits set
in the parameter "Predigit".

- Pseudo stairway entrance panel with 8-digit encoding. Type
6949 is used as a stairway entrance panel (secondary) in buil­ding complex type systems with 8-digit encoding/decoding,
where there are buildings with secondary entrances fitted with
stairway panels and buildings without stairway panels. Type 6949
performs all functions of a standard stairway panel without the
need for a secondary input.

CONTROLS AND ADJUSTMENTS

A - B) Pushbuttons for programming parameters of type 6949.
C) Trimmer for adjustment of current generator (typical value

25mA D.C., already factory-set).
D) DIP-switch for function programming.
E) LED for function programming phase.
F) ON/OFF jumper for current generator on/off activation (ON

= jumper activated, OFF = jumper deactivated).
G) Connector for connection of programmer type 950B.

TERMINALS

+I) The terminal is activated to switch off the monitor connec-

ted to the cable riser at the start of a call and at the end of
a conversation. The terminal is connected to power supply
6948 if specified on the diagram.

CH) The terminal is activated when a call is made from the

entrance panel or when the entrance panel is used to call
an internal unit via a main entrance panel or switchboard.
The terminal remains active for the time set in parameter

7. The terminal is connected to power supply 6941 or 6948
if specified on the diagram.

P1, P2) The terminals enable control, by means of two external

switches, of the conversion of functions in switchboard call
mode. To be used when there is more than one switch­board in the same system.

- Pseudo stairway entrance panel with 4-digit encoding. As per
the above application but for systems with 4 digit encoding/deco­ding.

- Digital signal amplifier with 8-digit encoding. Type 6949 is
used in systems where the same cable riser column has a high
number of interphones or monitors and there is the need to
amplify/regenerate the digital signal with 8-digit encoding/deco­ding. If the parameters "Initial user" and "Final user" are used,
type 6949 filters the call codes, passing on only those within the
set range.

- Digital signal amplifier with 4-digit encoding. As per the
above application but for systems with 4 digit encoding/decoding.

.

- Call filter with switchboards in parallel. Type 6949 is used to
filter calls from interphones or monitors to switchboards type
945B when there is more than one switchboard in parallel in the
same system (maximum 4 switchboards). A 6949 is connected to
each switchboard between the switchboard and the interpho­ne/&monitor cable riser, which will filter the calls, auxiliary
commands (F1, F2, F3, F4, F5) and the door lock release control
from the interphones/monitors, to use them as switchboard calls.
The filter control is managed by the parameter "Predigit". If two
external switches are connected to terminals P1 and P2 of type
6949, the filter configuration can be modified in remote mode,
enable switching of calls from one switchboard to another.

-) Common contact terminal for P1 and P2.

F2) The terminal is activated when type 6949 receives the code

for the second auxiliary function. The terminal remains
active for the time set in parameter 5. The terminal is
connected to power supply 6941, 6942 or 6948 if specified
on the diagram.

F1) The terminal is activated when type 6949 receives the code

for the first auxiliary function. The terminal remains active
for the time set in parameter 5. The terminal is connected
to power supply 6941, 6942 or 6948 if specified on the
diagram.

SR) The terminal is activated when type 6949 receives a door

lock release code. The terminal remains active for the time
set in parameter 6. The terminal is connected to power
supply 6941, 6942 or 6948 if specified on the diagram.

1) The terminal enables digital communication between the
switchboard, monitor, interphone, digital distributor and the
stairway entrance panel.

6) The terminal enables the transmission and reception of
digital codes between type 6949 and the switchboard or
between type 6949 and a main entrance panel.

5) Supply voltage terminal. The supply voltage
must be between 11.5V D.C. and 13.5V D.C.

4) Negative supply voltage terminal.

V+) +5V D.C. output terminal. Connected only if specified on

the wiring diagram

Configuration

The operating mode of type 6949 is selected on
the DIP-switch (as shown in the figures below).

Operation as converter of codes from 4 to 8 digits
and vice versa, from panel to panel. Converts
codes without activation of terminals CH and +I.

PRELIMINARY OPERATIONS

On completion of installation of all devices and connections, power
up the system, and check, by means of the LEDs on the power
supplies, that all the power supplies used are in fact supplying
power.
Before programming devices, wait at least ten seconds after the
system has been powered up.
Then check and, if necessary, program the operating parameters of
the entrance panels and/or switchboard.

The interphone and monitor call codes should be programmed
after programming (if required) the technical parameters of the
entrance panels and/or switchboard and other specific devi­ces.

PROGRAMMING

Type 6949 requires two programming phases: configuration of the
device type and technical parameter programming.

Operation as converter of codes from 4 to 8 digits
and vice versa, from panel to interphones/moni­tors. Enables replacement of a panel by converting
the codes and executing commands CH and +I.

Digital signal amplifier with 4-digit encoding, from
panel to panel. Executes code repetition without
activation of terminals CH and +I.

Digital signal amplifier with 4-digit encoding, from
panel to interphones/monitors. Enables replace­ment of a panel by repeating the codes and execu­ting commands CH and +I.

activation of terminals CH and +I.
