GENERAL RULES FOR INSTALLATION
Wiring should be installed in separate lines from electrical and industrial
cables. The use of coloured conductors will facilitale connections. For
the camera entrance panel installation, please, note that:
A) Camera operates from -5° + 50° C; to avoid overheating, protected it
from sunlight with some form of shelter.
B) Lens must be protected against direct light (sun, car headlights, etc.).
C) Person to be framed by camera must be illuminated from the front. If
lighting is insufficient use an additional external lamp powered direct-
ly by the mains.
D) Before closing unit, clean protective glass and lens, repeat this oper-
ation from time to time.
Power supply Art. 6681 must be placed in a dry place far from sources
of dust and heat. To facilitate check-ups and adjustments, make sure
that the place is easily accessible. Fix power supply to wall with proper
support and fixing screws provided with the package or inserting it with
proper DIN module. Before connecting it, ensure that conductors are not
interrupted or short-circuited.
Installation should be made in lines separated from electric mains. To
ensure user safety, all units run on low voltage and are separated from
electric-mains by an high isolation transformer. It is advisable, in any
case, to instal a thermal magnetic switch with an adequate capacity
between the supplying mains and the unit. When repairing and/or ser-
vicing the power supply it will be sufficient to loosen the screws placed
on the front side to remove the front panel, after having switched off the
power.
N.B. All diagram instructions must be carefully complied with. Respect
wire sections and distances.
OPERATION
The video door entry installation consists of one camera and one speech
unit entrance panel, one power supply and one or more monitors. When
an entrance panel push-button is pressed, the ringtone rings in the
corresponding apartment. Almost immediately the image of the caller
appears on the monitor. The camera coverage area is illuminated by
invisible infrared LED'S incorporated in the entrance panel. This illumin-
ation is not visible to caller.
To communicate with the outdoor speech unit, the user must press the
push-button marked
until the end of the conversation.
The monitor switches off after a set time, thereby terminating any conver-
sation in progress.
The system turns itself off automatically after a preset time, adjustable
from 30 to 90 seconds using potentiometer P1 inside the power supply.
If the caller presses another user's push-button, the previously called
monitor is automatically disactivated without waiting for the end of the
preset time.
If desired, the user may activate the door lock release push-button. In this
case, door-opening time may be varied from 1 to 30 seconds using the
potentiometer P3.
For simultaneous activation of two or more monitors, one extra power
supply type 6582 must be installed for each additional monitor or type
6583 for more monitors.
A blocking circuit cuts off power to monitors if the line is overloaded or
short-circuited. The power supply is also equipped with a specific device
to eliminate any buzzing on the voice circuit caused by the use of wires
that are too long and/or too thin. Push-buttons with name-tags are illumin-
ated through output 0-15 on power supply. Up to a maximum number of
three 24V 3W bulbs can be connected. An additional transformer, type
M832 or 832/030 is required for entrance panels with more than three
bulbs. Intercommunicating networks cannot be created.
Monitors to be used on this installation are type 5651, 5653, 7500.
These open voice monitors cannot be used with other models which do not
belong to the dual channel open voice series monitors.

TECHNICAL SPECIFICATIONS OF POWER SUPPLY TYPE 6681
Power supply for all two-channel open-voice video door entry systems
with "SOUND SYSTEM" call facility.
This new system is equipped with an electronic double tone generator
"SOUND SYSTEM" which replaces conventional alternative calling with
a buzzer or bell. The sound is emitted with two different tones thereby
allowing the user to immediately identify the source of the call (main
entrance, gate, garage, etc.). This feature provides economic and prat-
ical advantages since the use of several conventional sound emitting
systems is no longer required; the signal is emitted from a single loud-
speaker in the interphone.
The power supply may be used on installations either with conversation
privacy or without it. To create installations with conversation privacy use
only monitor type 5651 and 5653 provided with this function.
- 230V A.C. 50Hz supply (other voltages on request)
- 60VA maximum absorbed power.
- 18V D.C. 0.8A monitor supply.
- 13V D.C. 0,3A camera supply.
- 15V rectified voltage 0.25A continuous duty for push-button illumina-
tion (3x24V 3W max)
- Door lock output: 15V D.C. 1A intermittent cycle
- Amplified electric audio door entry system.
- Timer and automatic disconnection device of monitor previously acti-
vated.
- Interchangeable cards for quick maintenance.
- Removable terminal blocks.
N.B.: The particular type of installations requires the use of GALILEO
series door entrance panels with cameras arts. 559A, 559A/1, 559B or
speech unit type 930A. The use of this type of cameras or speech unit
allows the microphone to be located away from the loudspeaker, thus
allowing a balanced adjustment on the audio.
POWER SUPPLY OPERATING MODES
- Selector set A-B:
Position A- Operation with "Sound system" call and rectified 0-15V
output to prevent humming on the audio line.
Position B- Operation with "Sound system" call and 0-15 V A.C. output
PROTECTION OF POWER SUPPLY:
- Primary coil of transformer by PTC SIEMENS C840
- 1st. secondary coil for internal electronic supply by F 3,15A 250V (F1)
fuse.
- 2nd. secondary coil for lock supply by PTC SIEMENS C945
- Electronic protection against short-circuits and overloads on monitor
cable riser.
- Electronic protection against overloads to outdoor unit.
ADJUSTMENTS
P1 - Activation time adjustment for monitor and camera.
P2 - Volume adjustment of speech unit.
P3 - Activation time adjustment for electric lock.
N.B.: The electric door lock must operate by way of an intermittent cycle
so that one operating period corresponds to 5 rest periods, thereby pre-
venting the protection device from overheating (one period corresponds
to the door lock activation time).
Dimensions type 6681: 208x135x72 - Weight: 1.4 Kgs.
