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-

With the handset lifted and speech lines open to the entrance panel, press this button to open the door. If the terminal “LD”

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.

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.

    Why is the intercommunicating call not working on my Videx 6256 Intercom System?
    • D
      Daniel JohnsonAug 25, 2025
      If the intercommunicating call feature is not working on your Videx Intercom System, it could be because the ”Key” button was pressed a number of times different from the videophone address value. To solve this, check the address of the videophone you are calling and try again, pressing the “Key” button the correct number of times.

    How to fix Videx 6256 when door station doesn't call extension?
    • G
      Gerald MossAug 26, 2025
      If your Videx Intercom System's door station isn't calling the extension and the bell LED is on for 2 seconds, the issue could stem from several causes: * Incorrect wiring between the door station and videophone: Check the 6 common wire connections, especially wire “1” (speech line/data). * Insufficient cable size: Increase cable size or double up using two wires for each connection. * Incorrectly programmed videophone address: Verify the videophone address on the dip-switches. * Address change without system reboot: Power down the system and then power it up again to detect the new videophone address.

      Kaitlyn ColonSep 16, 2025
      If your Videx Intercom System's external call works but the communication fails when answered, the cause may be that the cable size is too small. The suggested solution is to increase the cable size or double up using two wires for each signal.

    Why can't I open the door on my Videx 6256 Intercom System even though the key LED is on?
    • K
      Kimberly MatthewsSep 8, 2025
      If you cannot open the door during a conversation on your Videx Intercom System, but the key LED on the door station activates, there could be a few reasons: * The J2 jumper might be in the wrong position. * The electric lock wires might be unconnected or shorted. * The electric lock type might be incorrect. To resolve this: 1. Check the J2 position on the door station. 2. Check the electric lock wire connections. 3. Ensure the electric lock type (AC or DC) is suitable for the chosen J2 position.

    • K
      Kristy HarrisSep 8, 2025

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