Legacy access control security system modernization apparatus
First Claim
1. An apparatus for extending the functionality of a legacy security system that controls access to at least one portal, wherein:
- said legacy security system comprises a plurality of legacy tokens, a legacy token reader and a legacy control panel,each legacy token carries a legacy-system access key,said legacy token reader and said legacy control panel are communicatively coupled together over first and second data channels,said legacy token reader has first and second data channel outputs for connecting to said first and second data channels,said legacy control panel has first and second data channel inputs for connecting to said first and second data channels, andsaid legacy control panel is programmed to grant access to the portal in response to reading a serial data stream that carries an authorized legacy-system access key, said apparatus comprising;
a secondary token reader operable to communicate with secondary tokens containing secondary-system access keys;
a secondary control panel in communication with said secondary token reader, said secondary control panel having a legacy-reader interface, a legacy-controller interface, a memory, and a rights-management interface whereinthe legacy-reader interface is adapted for electrical connection to the first and second data channel outputs of the legacy token reader to enable communication with said legacy token reader,the legacy-controller interface is adapted for electrical connection to the first and second data channel inputs of the legacy control panel to enable communication with said legacy control panel,the memory is adapted to store an access rights list of secondary-system access keys associated with access rights to the portal,the rights-management interface is adapted to accept programming input to update and manage said access rights list, andthe secondary control panel has an operational mode adapted to (a) transmit a memorized authorized legacy-system access key in response to an evaluation, using said access rights list, that a secondary-system access key received from a secondary token is associated with rights to access the portal, and (b) transmit any legacy-system access keys received from a legacy token to the legacy control panel without evaluation against said access rights list.

Abstract
A system is provided for upgrading a legacy security system having a legacy control panel and a legacy card reader, without interfering with legacy system operation. A new control panel is installed between the legacy card reader and the legacy control panel. Also, a new token reader is installed next to the legacy card reader and connected to the new control panel. The new control panel passes credentials it receives from the legacy card reader to the legacy control panel, avoiding interference with legacy system operation. When the new control panel receives credentials from the new token reader, it evaluates them against an access rights list administered independently of the legacy access rights list. When the new control panel determines that an access request should be granted, it sends a memorized legacy credential associated with full access rights to the legacy control panel, causing it to open the door.

8. A method of using a legacy control panel and a secondary control panel to regulate access to a doorway, the method comprising:
-
receiving an access credential from a token reader communicatively coupled to the secondary control panel; using the secondary control panel to evaluate the access credential against an access rights list that is associated with the secondary control panel; transmitting a memorized legacy access credential from the secondary control panel to the legacy control panel; and using the legacy control panel to engage or disengage a lock mechanism to enable passage through the doorway. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of upgrading a legacy security system having a legacy token reader with data-zero-bit and data-one-bit outputs, a legacy control panel with data-zero-bit and data-one-bit inputs, and data-zero-bit and data-one-bit wires connecting the legacy token reader'"'"'s data-zero-bit and data-one-bit outputs to the legacy control panel'"'"'s data-zero-bit and data-one-bit inputs, the method comprising:
-
installing a secondary control panel in proximity with the legacy control panel, wherein the secondary control panel has a data-zero-bit input, a data-one-bit input, a data-zero-bit output, a data-one-bit output; disconnecting the data-zero-bit and data-one-bit wires from the legacy control panel'"'"'s data-zero-bit and data-one-bit inputs; connecting the data-zero-bit and data-one-bit wires to the secondary control panel'"'"'s data-zero-bit and data-one-bit inputs; running new wires from the secondary control panel'"'"'s data-zero-bit and data-one-bit outputs to the legacy control panel'"'"'s data-zero-bit and data-one-bit inputs; installing a secondary token reader in proximity with the legacy token reader; providing a communicative coupling between the secondary token reader and the secondary control panel; and maintaining a communicative coupling between the legacy token reader and the secondary control panel. - View Dependent Claims (16, 17, 18, 19, 20)
