1. A door security system comprising:
- latch means for latching a door;
lock operator means for selectively locking and unlocking said latch means;
an input console comprising;
first reader means comprising a key pad for receiving a personal access code;
second reader means for receiving an electronic code from a coded key;
controller means for controlling said operator means, said controller means having a powered down mode for power conservation, and an active mode, and said controller means being transformed to the active mode upon applying an input at one of said first reader means and said second reader means, said controller means comprising;
memory means for storing at least one valid personal access code and at least one valid electronic code;
processor means communicating with said memory means and said first reader means and said second reader means for processing information in one of at least a first processing mode and a second processing mode and automatically switching between said first and second processing modes in response to detecting inputs at said first reader means or said second reader means wherein in said first processing mode said processing comprises identifying a personal access code input at said first reader means, comparing said personal access code to at least said one valid access code and generating a first RELEASE signal in response to a positive comparison and, in said second processing mode said processing comprises identifying an electronic code input at said second reader means, comparing said electronic code to at least said one valid electronic code and generating a second RELEASE signal in response to a positive comparison,wherein said operator means is responsive to said first and second RELEASE signals.

Abstract
An electronic door security system employs an input console having two 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 either reader transforms the controller to a power-up mode.

10. A door security system comprising:
-
lock operator means for selectively locking and unlocking a latch assembly; an input console comprising; first reader means for receiving a first input code; second reader means for receiving a second input code; and controller means for controlling said operator means, said controller means having a powered down mode for power conservation and an active mode, and said controller means transforms from said powered down mode to said active power mode upon application of an input to one of said first reader means and said second reader means, said controller means comprising; memory means for storing a set of valid first codes and a set of valid second codes; processor means communicating with said memory means and said first reader means and said second reader means for processing information in a first processing mode and a second processing mode and automatically switching between said first and second processing modes in response to inputs at said first reader means or said second reader means wherein in said first processing mode said processing comprises identifying a first code input at said first reader means, comparing said first code to said set of valid first codes and generating a first RELEASE signal in response to a positive comparison and, in said second processing mode said processing comprises identifying a second code input at said second reader means, comparing said second code to said set of valid second codes and generating a second RELEASE signal in response to a positive comparison; and on-board power means for powering said operator means and said controller means, wherein said operator means is responsive to said first and second RELEASE signals. - View Dependent Claims (11, 12, 13)
