Abstract

A security control system includes a remote access control system to receive wireless information from a central access control system. The remote access control system includes a remote access controller electrically coupled to a remote wireless communicator. The remote access controller receives information from the remote wireless communicator and uses the information to control locking and unlocking of the door. The remote wireless communicator also transmits wireless information to the central access control system and a switch is provided for selectively choosing between the receiving and transmitting the wireless information. The remote wireless communicator communicates via RF information, such as spread-spectrum RF. The remote access control system also includes a reader to read user data when presented to the reader.

Claims

1. A security control system configured to control the locking and unlocking of a plurality of doors in a facility, the wireless security control system comprising:

a central access control system having a central access controller and

a plurality of central wireless communicators electrically coupled to the central access controller, and

a plurality of remote access control systems located remotely from the central access controller, each remote access control system being adapted to be mounted to a respective one of the doors to control locking and unlocking of the respective door, each of the remote access control systems having a remote access controller and a remote wireless communicator electrically coupled to the remote access controller, the plurality of central wireless communicators and the plurality of remote wireless communicators being configured to communicate information wirelessly between the central access controller and the plurality of remote access controllers.

2. The security control system of claim 1, wherein the central access control system further includes a bus and the central access controller is electrically coupled to the plurality of central access communicators by the bus.

3. The security control system of claim 2, wherein the bus is controlled by a local area network protocol.

4. The security control system of claim 1, wherein the plurality of central wireless communicators communicate with the central access controller and with the plurality of remote wireless communicators using RF technology.

5. The security control system of claim 1, wherein each of the remote access control systems periodically initiates wireless communication with the central access control system and the central access control system transmits user updates to the respective remote access control system in response to the wireless communication periodically initiated by the respective remote access controller.

6. The security control system of claim 1, wherein each central wireless communicator is designated to communicate wirelessly with an associated one of the remote access control systems.

7. The security control system of claim 1, wherein each central wireless communicator communicates wirelessly with more than one of the remote access control systems.

8. The security control system of claim 1, wherein each of the remote access control systems further includes a reader electrically coupled to the remote access controller and adapted to read user data and each of the remote access control systems periodically transmits the associated user data to the central access controller.

9. The security control system of claim 1, wherein each remote access controller is configured to transmit wireless information through the associated remote wireless communicator and at least one central wireless communicator to the central access controller to provide the central access controller with user access information.
