How do i change the time for activation of the siren on Accenta opyima g3?

WITHOUT THE ENGINEERING CODE YOU CANT DO THIS
I WOULD SAY IT IS NOT A BELL DELAY BUT THE TIME YOU HAVE TO COME IN FROM THE ENTRY/EXIT DOOR WHICH BY DEFAULT IS 30 SECONDS WHICH IS STANDARD AND I WOULDNT RECOMMENED ANYTHING LESS
THIS DELAY DEPENDING ON HOW IT IS SET UP IS ONLY ON THE ENRTY/EXIT DOOR / DETECTOR IF YOU TRIGGER ONE OF THE DETECTORS WICH IS NOT ON THE ENRTY ROUTE THE ALARM SHOULD SOUND STRAIGHT AWAY
