button in response to a call from a main entrance panel will release
the lock connected to the main entrance panel from which the
call was made, as well as the lock connected to the secondary
entrance panel associated with the apartment station concerned. In
the second case, pressing the apartment station door lock release
button in response to a call from a main entrance panel will release
only the lock connected to the main entrance panel with digitizer
from which the call was made: a second call will have to be made
from the secondary entrance panel before the lock connected to it
can be released.

STEP 6 - Password

This step is not used. Direct door lock release via special codes is not
possible in systems equipped with digitizers.

BUSY SIGNAL VOLUME ADJUSTMENT

The digitizer generates a busy signal when a call is in progress from
another digitizer, entrance module or guard door switchboard station.
Volume of this signal can be adjusted by means of the trimmer located
adjacent to the jumpers.

NOTE:

In situations a) or b) as described above, where multiple
digitizers are connected directly to each other for system
expansion, all trimmers must be set to the same volume.

SPEAKER

AND

MICROPHONE

VOLUME

ADJUSTMENT FOR SPEAKER UNIT

Adjust speaker and microphone volume for the entrance panel speaker
unit associated with the digitizer as directed in the instruction sheet.

NOTICE:
The speaker unit must be set up to operate with electronic call
tone signaling doorphones and monitors (terminal 1A) or with
conventional buzzer type apartment station equipment (terminal 1).

REPLACING AN OLD DIGITIZER

•

STEP 1:

−

Install jumper PT3 P/S if digitizer is confi gured for
use at a main entrance panel

−

Remove the jumper is digitizer is confi gured for use
at a secondary entrance panel.

•

STEP 2:

−

Install jumper PT1 in position 1.

•

STEP 3:

−

See instructions, noting that fi rst-generation systems
cannot be used with confi guration c), TYPE 2.

•

STEP 4:

See instructions.

•

STEP 5:

See instructions.

•

STEP 6:

See instructions.

Systems with earlier-model digitizers can operate only with conventional
type apartment station equipment. Terminal 1 on speaker unit must
thus be connected rather than terminal 1 A.

OPERATION

An acoustic signal is generated each time a call key on the entrance
panel is depressed.
When a key on the entrance panel connected to the digitizer is
actuated, the ringer at the called apartment station will be activated for
the entire period that the key is held down. A protection feature will
interrupt ringing if the key is held down for more than 5 seconds).

Code numbers assigned via the two selector switches will depend on
two factors:

•

Whether the digitizer is confi gured for use at a main or secondary

entrance panel;

•

If it is confi gured for a secondary entrance panel, on the installation

type.

Code numbers to be assigned to digitizers for each type of application
are shown on the installation diagrams.

STEP 4 - Engaged time (Jumper PT2: 10”/20”/40”)

This  parameter  is  used  in  systems  with  two  or  more  main  entrance
panels featuring automatic switching between them. In such situations,
it  is  necessary  to  ensure  that  a  conversation  originating  from  an
entrance panel will not be cut off for a certain minimum duration, which
may be programmed from 10 to 40 seconds. During this programmed
minimum duration, which is called the “engaged time”, calls cannot be
made from the other entrance panels, where an intermittent warning
tone  will  be  emitted  to  indicate  that  they  cannot  be  used  unit  the
programmed engaged time has ended.
Once the programmed engaged time has ended, an ongoing call will be
interrupted immediately if a call is made from another entrance panel.
The  engaged  time  parameter  is  also  used  for  secondary  entrance
panels. When a main entrance panel or guard door switchboard station
makes  a  call  to  an  apartment  station  which  is  physically  connected
to the riser cable associated with a given secondary entrance panel,
it  will  not  be  possible  to  make  calls  from  this  panel  for  the  entire
programmed engaged time.

•

Move the jumper to 10” to establish an engaged time of 10 seconds

•

Move the jumper to 20” to establish an engaged time of 20 seconds.

•

Move the jumper to 40” to establish an engaged time of 40 seconds.

It is advisable to confi gure all entrance panels in the system for the
same engaged time.

STEP 5 - Electric lock management (Jumper PT4)

•

Position the jumper to confi gure UNRESTRICTED DOOR LOCK

RELEASE:

•

If the digitizer is confi gured for use at a main entrance panel, the

electric door lock connected to it will be released at any time that
the door lock release button is pressed at any apartment station.

•

If the digitizer is confi gured for use at a secondary entrance panel,

the electric door lock connected to it will be released at any time
that the door lock release button is pressed at any apartment station
connected to its riser cable.

•

Remove the jumper to confi gure DOOR LOCK RELEASE PROTECTED

BY PRIVACY FEATURE. This means that the electric door lock
connected to the digitizer module will be released only when the door
lock release button is pressed at an apartment station that has been
called from the entrance panel with the digitizer in question. In
this case, the door lock can be released for a period at least equal to
the programmed engaged time but not exceeding 10 minutes.

The criterion selected for electric lock management is essential to
correct system operation.

ADHERE

THE

INSTRUCTIONS

BELOW:

CONFIGURATIONS OTHER THAN THOSE DESCRIBED CANNOT
BE USED.

•

In installations with a single main entrance panel and no secondary

entrance panels, the digitizer may be confi gured either for
UNRESTRICTED DOOR LOCK RELEASE or for DOOR LOCK
RELEASE PROTECTED BY PRIVACY FEATURE.

•

In type b) installations with two or more main entrance panels
