Abstract

An access control system dissipates voltage transients while allowing access control equipment to operate normally. The access control system utilizes an isolation patch panel which is provided with circuitry to prevent voltage transients from damaging access control equipment, while also enabling the access control equipment to be wired with standard Ethernet cabling.

Claims

1. An access control system for dissipating voltage transients while allowing access control equipment to operate normally, said access control system comprising:

an access control device;

a protection outlet to which the access control device is connected; and

an isolation patch panel to which the protection outlet is connected;

wherein said isolation patch panel comprises an input connection, an output connection, and a protection circuit providing isolation between the input connection and the output connection.

2. The access control system of claim 1 further comprising an Ethernet switch connected to said input connection.

3. The access control system of claim 1 wherein said isolation patch panel is connected to said protection outlet via EIA/TIA-586-A category 5 cabling.

4. The access control system of claim 1 wherein said protection outlet comprises a protection outlet protection circuit, an input connection, and an RJ-45 jack output connection, said protection outlet protection circuit providing isolation between said input and said RJ-45 jack output connection.

5. The access control system of claim 4 wherein said input connection of said protection outlet comprises a 110-punch down block connection.

6. The access control system of claim 1 wherein said protection outlet comprises local power and auxiliary contact connections adapted to accept Power over Ethernet and supply power to said access control device.

7. The access control system of claim 1 wherein said protection circuit of said isolation patch panel directs high-voltage transients to ground.

8. An access control system comprising:

an access control device;

a protection outlet to which the access control device is connected, said protection outlet comprising an auxiliary contact connection to said access control device; and

an isolation patch panel to which the protection outlet is connected;

wherein said isolation patch panel comprises an input connection, an output connection, a protection circuit providing isolation between the input connection and the output connection, and an auxiliary contact accepting an auxiliary signal and forwarding said auxiliary signal to said auxiliary contact connection of said protection outlet.

9. The access control system of claim 8 wherein said access control device is a door lock and said auxiliary signal is a door unlock signal.

10. The access control system of claim 8 wherein said access control device is a door lock and said auxiliary signal is a door lock signal.

11. The access control system of claim 8 wherein said auxiliary contact of said isolation patch panel is connected to a door unlock override device.

12. The access control system of claim 8 wherein said isolation patch panel is connected to said protection outlet via EIA/TIA-586-A category 5 cabling.

13. The access control system of claim 8 wherein said isolation patch panel is further connected to an Ethernet switch.

14. The access control system of claim 13 wherein said Ethernet switch is connected to an access controller.

15. A patch panel for dissipating voltage transients, said patch panel comprising:

a plurality of input connections;

a plurality of output connections; and

a plurality of protection circuits, each of said protection circuits providing isolation between one of said input connections and one of said output connections and directing high-voltage transients to ground.

16. The patch panel of claim 15 wherein said plurality of protection circuits are adapted to allow Power over Ethernet to pass from said input connections to said output connections.
