Yes there is.

One report said he had a used ticket on him when he was arrested.

Based on that, he probably went in normally, slipped out the exit
(why no alarm?), rigged the door, dressed up and came back in.


If it's like a lot of commercial alarm installations that I've seen
it was wired with surface mounted switches & exposed wiring. Then all
you need is a jumper with a couple alligator clips to jump the switch on
the door. I've seen more than one door where the switch had been
bypassed & left that way after it went bad.

If it's installed correctly, the EOLR would prevent the jumper trick. It
probably had no EOLR supervision.

In any case, there should be two systems monitoring the exits, with
the switches inside the door frames. One for security, and a second as
part of the burglar/fire alarms

Yup, one for the alarm and one for a door position switch for the
employees to monitor propped doors. I've installed lots of systems on
college campus dorms that's all it did - sound the keypad with a zone
indicator saying which door has been open for more than "x" seconds.
