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.
Claims23
A security system for use with an exit door hingedly mounted in a door frame, said security system comprising:
- an electrically operated door locking mechanism having a locked condition for securing the exit door in a closed position, and an unlocked condition for allowing the exit door to be opened;
- trigger switch means for demanding egress through the exit door when said trigger switch means is actuated;
- control means for operating said electrically activated door locking mechanism, said control means including a timer for timing an egress delay period, said timer being started when said trigger switch means is actuated, said control means causing said electrically operated door locking mechanism to go from said locked condition to said unlocked condition when said timer finishes timing said egress delay period
- means for providing an alarm when said trigger switch means is actuated;
- and
- means associated with the exit door, for providing an informative output regarding the condition of said electrically operated door locking mechanism following the actuation of said trigger switch means, wherein said means for providing an information output comprises:
- means for providing an indication of the time remaining until said electrically operated door locking mechanism will go from said locked condition to said unlocked condition.
