ive faced this problem before, it wasn't the alarm going off we had to worry about tho, it was that goddamned beeping it does when anything is opened that would warn the dude's parents we had to worry about. solution? put a pillow firmly up against the idiot box that actually gives off the noise, if the alarm isn't engaged (i.e. not going to trigger the real alarm process) and you block out that damned idiot box with a pillow, she gets out without being detected.... if it's the actual alarm you have to worry about, forget this post entirely... oh yea, i wouldn't advise trying to unplug anything... we tried that, all it did was give us a headache and two suspicous parents (the alarms went off...)
