James,
Yes I enabled Program 2 to have 2 zones omitted and Program 3 to have all 4 PIR zones omitted ( very rare occasion of house overload !). They were set up in engineer mode, but when in user mode following the part set instructions selecting a "Program" did not silence the alarm bleeping ( first indication of a problem). The system just didn't recognise their existence. I'm unsure of the difference between part set and omitting zones, since the manual for part set states that it achieves it by removing zones that are not required to be set for whatever reason. Program 1 is a full all zone set for a total house empty period. Hope that makes sense James?
Al-yeti, I too have experienced manual misinformation on other alarm systems. I was confident that I had followed the steps as advised. A online manual of a old very forerunner of the Gen 4 gave me a clue that the instructions were wrong. The "C" (Eye) used to be simply labelled "Omit" . A big clue and whilst I acknowledge that manufacturers can completely rehash things, many changes can be cosmetic and trendy. The original basics often underpin modern technology and trends. Cars are great example of that.
