Abstract

In a location where a number of entities share a common area and where those entities wish to exclude unauthorized individuals yet desire access for a set of individuals from each entity, a system, using networking techniques, integrates a plurality of independent entity access control systems in which each system authorizes credentials from one of the plurality of entities to control access to each individual entity area.

Claims

1. An integration system for use with a plurality of autonomous access control systems, wherein said access control systems comprise separately maintained databases of permitted access indicia, and wherein said integration system accepts an access request from one point and communicates said access request to said access control systems, which have a different function from said integration system, said integration system comprising

a reader capable of receiving an access indicium from a user requesting access to a controlled area or system,

a data network in signal communication with said reader and capable of directing said access indicium to a particular access control system, and

a plurality of receivers in signal communication with said data network, each of said receivers in signal communication with an access control system, and capable of receiving said access indicium, providing said access indicium to its respective access control system via a pseudo-reader, receiving from said access control system a signal indicating whether said access indicium is valid, and, if said access indicium is valid, transmitting a signal to an access control device to allow access to a controlled area or system.

2. The system of claim 1, wherein said access indicium comprises a facility code identifying the access control system to which the access indicium should be directed.

3. The system of claim 1, wherein an access control system receiving said access indicium returns a denial of access signal if it determines that said access indicium is invalid.

4. The system of claim 1, wherein said access control device comprises a timer determining a period of time within which the access control device must receive said signal to allow access to a controlled area or system.

5. The system of claim 1, wherein said signal to said access control device comprises an access hold open time.

6. The system of claim 1, wherein said access control device comprises a means of limiting the access hold open time.

7. The system of claim 1, additionally comprising a data log in signal communication with said data network.

8. The system of claim 7, wherein said data log records data related to attempts to utilize invalid access indicia.

9. The system of claim 7, wherein said data log records an audit of communications transmitted via said data network.
