OPERATION
The video installation without coaxial cable has been designed to reduce to the minimum mounting operations and particularly when carrying out remaking
works. The installation can use the 5-wire conductors of old intercom (4 common + 1 call) without using a shielded cable for the video signal. The installation
consists of one camera entrance panel, speech unit, one power supply and one or more monitors. When a push-button of entrance panel is pressed, the
ringtone rings in the corresponding apartment. Almost immediately the image of the caller appears on the monitor. The coverage area is illuminated, in a
invisible way, by infrared LED'S (when using a B/W camera) or white light (when using a color camera) incorporated in the entrance panel. If desired, the
user may simply raise the interphone, communicate with the caller and, if appropriate, activate the door lock release. In this case, door-opening time may be
varied from 0.5 to 30 seconds using the potentiometer P3.
ATTENTION: the installation is completely switched off by pressing the lock release push-button.
The system turns automatically off after a preset time, adjustable from 30 to 130 seconds using potentiomenter P1 inside 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 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 the monitors
if the line is overloaded or short-circuited. Push-buttons with name-tags are illuminated through output 0-15 on the power supply. Up to a maximum number
of three 24V 3W bulbs can be connected. Additional transformers type M832 or 832/030 are required for entrance panels with more than three bulbs.

Note:
The electric door lock must operate with an intermittent cycle so that 5 rest periods correspond to one operation period, if not there is a a risk of
overheating of the protection device (one period corresponds to the door lock insertion time).
