ABSTRACT:
An entrance for buildings comprises first and second doors mounted in a common door frame, each door including a lock stile positioned adjacent a lock stile of the other door when the doors are closed. A panic device is mounted on at least one of the doors for emergency opening thereof and a retractable latch is extended between the stiles of the doors when closed for minimizing or eliminating the unauthorized forced separation of the stiles into a position wherein the panic device can be actuated with an implement inserted from outside the entrance to release and open the door. Mechanism is included for interconnecting the latch and the panic device for retraction of the latch when the panic device is actuated for opening the door, thus providing both a safe and a secure entrance system.
