A door control unit useable at a facility having a door with a door lock and a lock release apparatus, by a cardholder carrying an entry card containing card identity information and wherein the facility has a control system with a program containing the card identity information and also has a main paging transmitter connected to the control system for wirelessly transmitting an information signal containing the card identity information to the door, the door control unit comprising:

• an entry card reader positionable adjacent the door to read the entry card to obtain the card identity information;
• a local paging unit positionable adjacent the door and including a local paging receiver for receiving said information signal from said main paging transmitter by wireless communication therewith;
• a controller electrically connected with said local paging unit and including a memory to store card identity information received from said local paging unit, said controller electrically connected with said entry card reader to receive card identity information from said entry card reader, said controller comparing the card identity information obtained from said card reader with the entry card identity information received from said local paging unit and generating a lock actuation signal for delivery to the door lock release apparatus when the entry card read by said cardholder is authorized to unlock the door lock.

A door lock control apparatus for use at a facility having at least one door in order to lock and unlock a door lock on the door, comprising:

• a main paging transmitter for wirelessly transmitting an information signal to the door;
• a door control unit, including a paging unit positionable adjacent the door, said paging unit including a local paging receiver for receiving said information signal from said main paging transmitter by wireless communication therewith, said door control unit generating a lock actuation signal in response to receiving said information signal;
• and
• a door lock release apparatus positionable adjacent the door, and electrically connected to said door control unit to actuate the door lock between open and locked conditions in response to said lock actuation signal from said local paging unit.
