Abstract
The system includes a vestibule and a plurality of emergency exits interconnecting the secure area with the outside environment. The vestibule comprises a pair of security doors and the emergency exits comprise security doors having locking means and means for disabling the locking means in response to any one of several preselected egress corroborating events that are not likely to be associated with adversarial activity. The various preselected events may include non-emergency situations such as a request to leave or disable made by two persons within the secure area, a request to leave or disable made by a single person within the secure area plus security guard affirmation, and a request to leave or disable made by a single person within the secure area plus the expiration of a time delay triggered by the request. The various preselected events may also reflect emergency situations such as activation of an alarm system triggered by single, double or multiple alarms that bring into question the safety of insiders in the secure area. The emergency exits may be in the form of an environmentally-hardened portal or a single security door.
