1. An access control module for controlling access through a door, comprising:

  • a power interface coupled to a merged power-communication cable, and controllably coupled to a processing computer in a processing module;

    said power interface providing a first electrical power to an access controlled door lock;

    said power interface providing a second electrical power to a communication interface;

    wherein said processing module, further comprises;

    said processing computer accessibly coupled with a processing memory containing at least one program step of a processing program system directing said processing computer;

    said processing computer first communicatively coupling with said communications interface coupled with a merged power-communication cable;

    said processing computer coupling with a peripheral interface coupled with said merged power-communication cable, with a door position sensor, with a request-to-exit switch, and with said access controlled door lock;

    wherein all communications between said access control module and a security network pass through said merged power-communication cable, all electrical power to said access control module passes through said merged power-communications cable, and said processing program system comprises the program step of;

    managing said power interface to distribute said electrical power; and

    controlling said access controlled door lock based upon interactions with said door position sensor, with said request-to-exit switch, and with said merged power-communication cable.
