alarm key pad silent?

Hi we have an Accenta/Optima 8EP396A compact panel with built in LED keypad, this has worked perfectly for the past 12 years, today on keying in the code there was no sound while depressing the code, what may be the problem and how to fix it please.

Key pad it's self

Does the sound normally come from the keypad itself or a separate speaker/sounder nearby? Let us know and we can go from there
