A control system is for a lock of a door movably disposed within a frame and having a latch engageable with the frame, an interior handle connected with the latch and an exterior handle connectable with the latch. A connective mechanism is configured to releasably connect the exterior handle with the latch and an input device is configured to generate an unlock signal. A controller is coupled with the input device and configured to operate the connective mechanism such that the mechanism connects the exterior handle with the latch. The controller is selectively operable in a standard mode where the controller operates the mechanism when the controller receives the unlock signal and a lockdown mode where the controller does not operate the mechanism when receiving the unlock signal. A lockdown-input device coupled with the controller is configured to generate a lockdown signal to switch the controller to the lockdown mode.

Lock control system with lock-down feature

An electronic door security system employs an input console having three readers for enhanced security. A microprocessor processes inputs applied at each of the readers to selectively permit access through a secured door. Application of an input to any of the readers transforms the controller from a sleep mode to an active mode.
