This is an actual problem on a current project, and I'm hoping some of you will have ideas to help out.  The doors and a portion of the hardware have already been installed, and the remaining hardware is on-site.  It's a double-egress pair in a health-care facility, and it is equipped with a system to prevent patients with Alzheimer's Disease or other conditions from "eloping".  There is a sensor in the vicinity of the doors which detects an approaching occupant wearing a transmitter bracelet, and when an occupant is detected the system automatically arms the delayed egress locks, which prevent the patient from leaving the unit before staff members can arrive.

As I read about the terrible movie theater tragedy in Aurora, Colorado, I thought about things from a door hardware consultant's perspective.  Could future tragedies be prevented by changing the way we think about the hardware on movie theater exits?  Because the suspect allegedly propped open the exit door so he could return during the movie with guns, explosive chemicals, and a protective vest, would monitoring or alarming the emergency exit have thwarted his attack?
