Abstract
A security system for use on doors which have an electrically operated door locking mechanism is disclosed, which security system is operative to provide a preset egress time delay following an effort to exit through the controlled door before actuating the door locking mechanism to unlock the door and allow egress. During the egress time delay, the system provides a visual input of the time remaining until the door locking mechanism will unlock the door to allow egress or access therethrough. In the preferred embodiment, a speech synthesizer and digital display is also utilized to inform the individual demanding egress or access of the delay, and to provide other information as desired.
