A door control apparatus useable in buildings or other facilities having many locked doors or rooms and requiring controlled access to the rooms, utilizes paging transmitters and paging receivers to transmit information from a central control system to individual door control units located at each controlled door. The door control unit may include a card reader for reading an entry card. Card identification information is transmitted wirelessly from a main paging transmitter connected with the control system and is received by the door control units at selected doors to define the card or cards which are to be accepted at each door control unit to open a controlled door. The invention also allows all or selected doors to be unlocked by a transmitted command from the control system to allow fast entry through such doors to fire crews or other emergency personnel. The door control unit may also transmit data to the control system using paging technology.
