What to do if my ELFON OPTIMA SL255 panel displays 'SHORT.LINE.' message?
If the ELFON Intercom System panel displays the message "SHORT.LINE.", it indicates a shorted handsets line. To resolve this, eliminate the short-circuit. After correcting the shorting issue, the panel may continue to display the shorting message for up to 10 seconds.
Why doesn't the code or RFID tag open the electric lock on my ELFON OPTIMA SL255?
If the general/individual code or RFID tag isn't opening the electric lock on your ELFON Intercom System, even without error messages, verify that the permission to open the electric lock using the general/individual code or RFID code is properly configured.
