Hi. I have the Accenta 8 also, which funnily enough I'm having problems with at the minute. I have Operating Instructions which won't help what I need but hopefully will help you...
'To Omit A Zone' During the exit period (after entering your code and selecting a program) press Omit. The exit tone will stop and the zones that are about to be armed will be displayed. Key in the zone number(s) to be omitted which will flash to confirm selection. Zone indicators which show steady are still about to be armed. When the selection is complete press set and the exit tone will continue.
Hope this helps.
