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 directly
by the mains.
D) Before closing unit, clean protective glass and lens, repeat this opera-
tion from time to time.
Power supply type 6680 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 servicing 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.
OPERATION
The video door entry installation consists of one camera entrance panel
with speech unit, one power supply and one or more monitors. The system
can operate with monitors and B/W or colour cameras and with or without
conversation privacy.
The power supply is not equipped with intercommunicating section; never-
theless it is possible to set up a monitor and/or intercommunicating inter-
phones network using switching module type 935A in conjunction with the
basic power supply.
When an entrance panel push-button is pressed, the ringtone rings in the
corresponding apartment. Almost immediately the image of the caller ap-
pears on the monitor. The coverage area is illuminated by built-in infrared
leds when using B/W camera, or by a built-in white light when using a
colour camera.
If desired, the user may simply raise the interphone, communicate with the
caller and, if appropriate, activate the door-opener. In this case, door-ope-
ning time may be varied from 1 to 30 seconds using the potentiometer P3.
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.
When testing the installed system, use trimmer P2 to adjust the optimal
volume of the speech unit. For simultaneous activation of two or more moni-
tors 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 only in
installations with "SOUND SYSTEM" call. Push-buttons with name-tags are
illuminated 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 0832/030 is required for entrance panels with more bulbs.

Technical specifications of power supply type 6680 - (6680/V03)
type 6680 is the basic power supply for all video door entry systems with
SOUND SYSTEM call and is equipped with an electronic double tone gene-
rator, which replaces conventional alternative calling with a buzzer or bell.
The sound is emitted with two different tones (present on terminals C1-C2)
thereby allowing the user to immediately identify the source of the call (main
entrance, gate, garage, etc.). This feature provides economic and practical
advantages since the use of several conventional sound emitting systems
is no longer required; the signal is emitted from a single loudspeaker in the
interphone. In some cases, savings can be made on the cable routing work
requirements for additional bell systems. Manufactured in copolymer class
V-0 housing; preset for mounting on cases with 12-Module DIN support or
with expanding plugs with screws.
- 230V A.C. 50Hz supply (other voltages on request)
- 60VA maximum absorbed power.
- 18V D.C. 0.8A monitor supply. (90 sec. ON, 90 sec. OFF)
- 13V D.C. 0.3A camera supply. (90 sec. ON, 90 sec. OFF)
- 15V rectified voltage 0.25A continuous duty output for push- push-button
illumination (3x24V 3W max)
- 15V A.C. 1A door lock output; intermittent service. (30 sec. ON, 150 sec.
OFF)
- Amplified audio door entry system.
- Timer and automatic disconnection device of monitor previously activa-
ted.
- Interchangeable cards for quick maintenance.
- Removable terminal blocks.
POWER SUPPLY OPERATING MODES
- Selector set A-B:
- "A" Position: operating with sound system call, to be used in case of
humming noises (caused by power supply, door lock or lamps) dectected
on the interphone line.
- "B" Position: normal operation with Sound System call, switching module
in "A" position only in case of humming noises on the audio line.
- "B" Position: operating with 15V A.C. call only. In this case power supply
6680 completely replaces power supply type 6580.
PROTECTION OF POWER SUPPLY:
- Primary coil of transformer by PTC
- 1st. secondary coil for internal electronic supply by F 3,15A 250V (F1)
fuse.
- 2nd. secondary coil for lock supply by PTC
- Electronic protection against short-circuits and overloads on
monitor cable riser.
- Electronic protection against overloads to speech 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 preventing
the protection
device from overheating (one period corresponds to the door lock
activation time).
Dimensions type 6680 - 6680/V03: 208x135x72 - Weight: 1.4 Kgs.
