It is possible to update this panel to 868 MHz panel if You change 434 MHz circuit board to 868 MHz circuit board, this circuit board is obtainable from 868 MHz zone expander, I tried it and it worked for motion detectors but some 868 MHz futures may not work, for example I tried and external siren wasn't worked.
