Thanks for advise. Keith

Hi. I had Scantronic 9800 system installed 20 years ago. It has given good service but the push buttons have become faulty over the years and we are now on the last four buttons that work reliably. Is there a compatible replacement available for the original 9825 remote keypad? If yes is it simply a case of switching off power, disconnect battery and swop over wires on keypad or does it need an 'expert'?
