Abstract
A modular electronic door security system includes an input device, a control module and an electro-mechanical lockset mounted to a door configured to facilitate electrical interconnections interiorly of the door. The input device and/or control module may be mounted in a user defined location on the surface of the door. An optional override mechanism allows access to secured areas in the event of system failure or emergency.

13. A modular door security system comprising:
-
a door having opposite first and second surfaces, a hinge edge and a latch edge separated by a first distance, an upper edge and a lower edge separated by a second distance, said second surface having a central portion comprising an area of said second surface at least ⅛
of said first distance from said hinge edge and said latch edge and at least ¼
of said second distance from said upper edge and said lower edge;
a lockset installed adjacent to said latch edge, said lockset including a latch projectable through said latch edge, an interior handle projecting from said first surface and an exterior handle projecting from said second surface, said interior handle capable of retracting said latch from a projected latched position;
a clutch mechanism which creates a selective mechanical coupling between said exterior handle and said lockset, said coupling enabling said exterior handle to retract said latch from said latched position;
