Couldn't the wire have been cut for a while? When Michael was yelling at Angel to turn the alarm off, he said he couldn't because it was wired into the guard room. That means there is obviously an on/off switch in the guard room. The switch could have been flipped off and the wire cut while Angel was on guard duty at some point. Then, to make the alarm go off, he just had to be sneaky and flip the switch on.
