PUSH BUTTONS FIG. 1

Service push button.

Shorts the “SB” terminal to GROUND (open collector 24Vdc 100mA max) while the button remain pressed.

Privacy ON-OFF button.

When the system is in stand-by, the pressing of this button activates (LED switched on) or disables (LED switched
o) the “privacy” service. The service is automatically disabled when the programmed privacy time expires. When
the service is enabled the videophone does not receive calls.

With speech lines open to the entrance panel, press this button to open the door. If the terminal “LD” is properly
connected the relevant LED remains switched ON until the door is closed.
Intercommunication only works when the system is in the stand-by condition.
Switch 4 of the SW1 dip-switch selects the type of intercommunication:
OFF Intercommunication between two apartments - press the key button to call the videophone(s) in the other

apartment. A busy tone will signal that the other videophone is in conversation with the door station and so
cannot be called.

ON Intercommunication between videophones in the same apartment

- press the key button one, two, three or four times to call videophone with extension address 1, 2, 3 or 4 (Set on
dip-switches 2&3 of SW1).

Any intercommunicating conversation is always interrupted by an external call (i.e. External calls take priority).

Intercommunication push button.

For an intercommunicating call, press as many times as the extension or address value to call (see SW3 Intercommu­nication Settings).

both switches must be “ON” only on the last videophone (looking at the connection order) while for all
other videophones both switches must be set to “OFF”.

Art.6758 - Installation instructions

1. In order to install the videophone, it is necessary to remove the cover, which contains all the electronics, from the base: press

lightly on the right part of the videophone and simultaneously pulling outwards the left part as shown in Fig. 1.

2. Put the base of the unit on the wall at approx 135cm from the nished oor to match the points for the xing holes “A” (Fig. 2)
remembering that the wires “D” (Fig. 3) must be fed through the large hole “E” (Fig. 3). If you use the ush mounting box 503,
embed it into the wall vertically at approx. 140cm from the nished oor and the base.

3. Following Fig. 3, make the holes “A”, insert the wall plugs “B” and x the base with the screws “C” feeding the wires “D”
through the hole “E”. If you have used the box 503, x the base to the wall through the holes “F” using the screws “C”.

4. As shown in Fig. 4, connect the wires to the removable terminals following the provided installation diagram. Connect the terminal
blocks to the electronics contained in the cover as shown in Fig. 5. Test system before closing.
Contrast and hue trimmers can be adjusted only if the videophone is open. To activate the display and see changes use the
“Camera Recall” function by pressing

button.

Note: while testing the system, it is advisable to hold the cover with your hand.

5. Once testing is complete and all the necessary adjustments are made, close the unit as shown in Fig. 6: rst hook in the right
part and then the left part until you hear a click.
