Admins knowing when the singularity gets free is of zero use to anybody. If it's free, it's too late already.
What I mean is if it showed on the power alert computer (and thus also engineering PDA) whether or not the emitters have power. Or, whether the generators have power. So if some saboteur decides to cut a wire, shut off SMS outputs, turn off emitters, or whatever else, you get a notice shortly after (or maybe you even have to look for it) saying "Singularity Containment Compromised". That gives the engineer time to run to engineering and try to get the power/wiring/emitter situation rectified, before it's call the shuttle time.
I just think it's way too easy to get the shuttle called with the simple act of cutting 1 wire, without any real possibility of it getting fixed, unless you get lucky and happen to see the emitters aren't firing before the field goes down. I know when I'm traitor, that's my go to move for getting the shuttle called. And if you put a beacon somewhere, (And actually turn the damn thing on) it's a guaranteed round ender when the singularity cuts the station in half.
There's really no other guaranteed round ender with no warning like that. Flooding the station with plasma is close, but there are warnings, and time to fix it, before everything's on fire.
