PUSH BUTTONS
Service push button
Shorts the “SB” terminal to GROUND (open collector 24Vdc 100mA max) while the button remain pressed.
Camera recall button
Pick up the handset then press the button (Press once for door/gate 1, twice for 2 and so on up to a maximum of 4 entranc-
es): the relevant LED switches ON and the monitor switches on showing the video from the door panel. The speech is also
live and the door can be opened by pressing .
Door-open / intercommunicating call button
With the handset lifted and 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 stand-by condition.
Switch 4 of the SW1 dip-switch selects the type of intercommunication:
OFF Intercommunication between two apartments - pick up the handset and 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
- pick up the handset and press the key button one, two, three or four times to call videophone with extension address 1, 2,
3 or 4 (Set on dip-switch 2&3 of SW1).
Any intercommunicating conversation is always interrupted by an external call (i.e. External calls take priority).
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.

    What to do if Videx 6256 Intercom System door station cannot call the extension?
    • I
      ivegaAug 23, 2025
      If the Videx Intercom System door station cannot call the extension, and the bell LED is on for 2 seconds, it could be due to several reasons: * Incorrect wiring between the door station and the videophone. * Insufficient cable size. * Incorrectly programmed videophone address. * Changing the videophone address without powering down the system. To solve this: 1. Check the 6 common wire connections, especially wire “1” (speech line/data). 2. Increase the cable size or double up using two wires for each connection. 3. Verify the videophone address on the dip-switches. 4. Power down the system and then power it up again to detect the new videophone address.

    • R
      Rachel WolfeSep 6, 2025

    How to fix bad video quality on Videx 6256 Intercom System monitor?
    • A
      Amanda CostaSep 5, 2025
      If the video quality on your Videx Intercom System monitor is poor, and the image is distorted or doubled, it could be due to several reasons: * V1, V2 signals being unconnected, reversed, or shorted. * The switches of the two-way dip-switch not both being in the ON position. * V1, V2 of the last Art. 316N (if present) not closed with a 75 Ohm resistor. To fix this: 1. Check that the wires are not broken or shorted. 2. Set both switches to the ON position. 3. Use 2x 75 Ohm resistors to connect V1 & V2 to 0V.
