Hi friends, I have a control panel which has 3 nos of 7 segment LED displays. The display indicates the Zone of the fire alarm sensor (001 to 999).
I need to design another alphanumeric display which takes the input from the control panel LED display unit. For eg.. Zone 001 should be displayed in the new box as D3317, 002 as D3327, 003 as B1143.... There should be an interface where the corresponding alphanumeric can be set for each zone.
Any ideas? Thanks...

Assuming that you aren't violating any codes by doing so, figure out the easiest way to pick of the data from the control unit and monitor that data with an MCU that uses a look-up table to determine what to display. The interface on how to configure the table contents can be done many different ways.
