Abstract

Disclosed is an entry system for a building having: a first door lock that includes a controller; wherein the first door lock is configured for encoding access rights to a first client keycard responsive to a first engagement with a master keycard.

First claim

What is claimed is:

1. An entry system for a building that includes a plurality of suites, each having a suite lock and a plurality of rooms, each having a room lock, the system comprising:
a first door lock that is a suite lock for one of the suites, that includes a controller;
wherein the first door lock is configured for encoding access rights to a first client keycard, that is a guest keycard, responsive to a first engagement with a master keycard,
wherein engaging the master keycard includes the first door lock monitoring the occurrence of a predetermined combination of actions proximate in time to the first engagement with the master keycard;
wherein monitoring the occurrence of the predetermined combination of actions includes the first door lock monitoring the occurrence of one or more additional engagements with the master keycard and receiving manual actuation of a first door handle of the first door lock;
wherein the first door lock is configured for granting access rights at a plurality of door locks to the first client keycard, wherein the plurality of door locks includes the first door lock and selective ones of the room locks within the suite, the selective ones of the room locks being less than all of the room locks within the suite.

2. The system of claim 1 , wherein the first door lock is configured for granting the access rights to the first client keycard for a predetermined period of time relative to a time of the first door lock.

3. The system of claim 1 , wherein the first door lock is configured for revoking any active access rights for any other client keycard if and for as long as communications over a network with a network hub are unavailable.

4. The system of claim 3 , wherein responsive to communications over the network with the network hub subsequently becoming available, the first door lock is configured for revoking access rights to the first client keycard.

5. The system of claim 1 , wherein the first door lock is configured for granting access rights at a plurality of door locks to a plurality of client keycards, wherein the plurality of door locks includes the first door lock and the plurality of client keycards includes the first client keycard.

6. The system of claim 5 , wherein the first door lock is configured for granting the access rights based on a system parameter encoded in the master keycard and the first door lock, and a sequence number the first door lock encodes onto the plurality of client keycards.

7. The system of claim 5 , wherein the first door lock is configured for revoking any active access rights for any other client key.

8. A method of controlling an entry system for a building that includes a plurality of suites, each having a suite lock and a plurality of rooms, each having a room lock, the building comprising:
a first door lock that is a suite lock for one of the suites, that includes a controller, the first door lock encoding access rights to a first client keycard, that is a guest keycard, responsive to a first engagement with a master keycard,
wherein engaging the master keycard includes the first door lock monitoring the occurrence of a predetermined combination of actions proximate in time to the first engagement with the master keycard;
wherein monitoring the occurrence of the predetermined combination of actions includes monitoring the occurrence of one or more additional engagements with the master keycard and receiving manual actuation of a first door handle of the first door lock;
wherein the method includes the first door lock granting access rights at a plurality of door locks to the first client keycard, wherein the plurality of door locks includes the first door lock and selective ones of the room locks within the suite, the selective ones of the room locks being less than all of the room locks within the suite.

9. The method of claim 8 , wherein the method includes the first door lock granting the access rights to the first client keycard for a predetermined period of time.

10. The method of claim 8 , wherein the method includes the first door lock revoking any active access rights for any other client key while communications over a network with a network hub are unavailable.

11. The method of claim 10 , wherein the method includes the first door look revoking access rights to the first client keycard responsive to communications over the network with the network hub subsequently becoming available.

12. The method of claim 8 , wherein the method includes the first door lock granting access rights at a plurality of door locks to a plurality of client keycards, wherein the plurality of door locks includes the first door lock and the plurality of client keycards includes the first client keycard.

13. The method of claim 12 , wherein the method includes the first door lock granting the access rights based on a system parameter encoded in the master keycard and the first door lock, and a sequence number the first door lock encodes onto the plurality of client keycards.

14. The method of claim 12 , wherein the method includes first door lock revoking any active access rights for any other client keycard.
