What does it take to be able to disable alarm panels reliably? I'm trying to make the transition from Eric to Frosty, and after the first attempt failed horribly due to setting off the alarm and being swarmed with endless waves of guards, I ground up karma with Eric to raise my Int (since that's what the alarm panel says is checked to disable it), and went back.

With 5 Int (only one short of the highest my troll can ever possibly get), I tried again, and still was unable to disable the generac office alarm panel even once, in over a half-hour of save-scumming (load a save at entry into generac, run over to panel, attempt to disable, get the "you failed, alarm went off" message, reload and try again, for half an hour). I checked the non-combat skills, and none appears to apply here, so as far as I can tell, Int score is the only think that has an effect here.

How is this supposed to work? Is setting off the alarms everywhere the intended primary path, with disabling them as an alternative that sometimes rewards 9-int humans, dwarves and elves with an easy run when they get a favorable roll, and isn't worth bothering with at all for orcs, trolls, or anyone not built around Int? Am I just not ready to switch from Eric to Frosty until I can just set off the alarm and fight my way through it?
