Abstract

A security system includes a central controller which communicates with a multiple of electronic door locks within a multi-room facility. The central controller communicates with each electronic lock through a room transceiver located proximate the electronic lock. A display communicates with the room transceiver to provide messages and other services to each room. In operation, the system provides a multiple of security and key tracking services. Each electronic lock receives instruction from the central controller such as access for a particular key or cancellation of keys through the in-room transceiver. Historical key tracking allows tracking and efficiency management of staff. A single staff person can also be located by searching for the predetermined code for the desired staff person. Maintenance of each electronic lock is also simplified.

Claims

1. A security system for a multi-room facility comprising:

a central controller;

an electronic door lock which is unlocked by a first key which unlocks only said electronic door lock and a second key which unlocks a plurality of other electronic door locks;

a lock transceiver in communication with said electronic door lock; and

a room transceiver located proximate said electronic door lock, said room transceiver in communication with said central controller and said lock transceiver to provide communication between said central controller and said electronic door lock, said central controller operable to identify each unlock event of said first electronic door lock.

2. The system as recited in claim 1, further comprising a display in communication with said transceivers to display information from said central controller.

3. The system as recited in claim 2, wherein said display comprises a television.

4. The system as recited in claim 1, wherein said central controller tracks a time representative of each unlock event.

5. The system as recited in claim 1, wherein said central controller tracks a code unique to said second key when said second key is inserted into said electronic door lock, said code communicated from said lock transceiver, to said room transceiver and from said room transceiver to said central controller.

6. The system as recited in claim 1, wherein said central controller communicates with a plurality of said electronic door locks to identify a history for said second key.

7. The system as recited in claim 1, wherein said central controller communicates with said electronic door lock to identify a status of said electronic door lock.

8. The system as recited in claim 7, wherein said status of said electronic door lock comprises a battery condition of a battery within said electronic door lock.

9. The system as recited in claim 1, wherein said central controller communicates with said electronic door lock to cancel said first key which previously unlocked said electronic door lock.

10. The system as recited in claim 1, wherein said room transceiver remotely communicates with said lock transceiver via two-way radio frequency.

11. The system as recited in claim 1, wherein said central controller communicates with said room transceivers over a local area network.

12. The system as recited in claim 1, wherein said central controller communicates with a plurality of locations over a wide area network, each of said plurality of locations comprising a plurality of said electronic door locks.

13. A method of communicating with a plurality of electronic door locks from a central controller comprising the steps of:

(a) communicating between a central controller and a plurality of room transceivers, each of the plurality of transceivers proximate an associated electronic door lock;

(b) communicating between each of the plurality of room transceivers and the associated electronic door lock; and

(c) tracking each unlock event for each of the plurality of electronic door locks.

14. A method as recited in claim 13, wherein step (c) comprises the step of:

tracking a time of each unlock event for each of the electronic door locks.

15. A method as recited in claim 13, further comprising the step of:

tracking a code unique to a key when the key unlocks any of the electronic door locks.

16. A method as recited in claim 13, further comprising the step of:

communicating with a plurality of the electronic door locks to identify a history for a predetermined key.

17. A method as recited in claim 13 further comprising the steps of:

recording a time a predetermined key unlocks a first electronic door lock; and

recording a time the predetermined key unlocks a second electronic door lock.

18. A method as recited in claim 13 further comprising the steps of:

recording a time the predetermined key unlocks a first electronic door lock; and

recording a time the predetermined key unlocks a second electronic door lock.

19. A method as recited in claim 13 further comprising the steps of:

identifying a status of each of the electronic door locks.

20. The system as recited in claim 13, further comprising the steps of:

identifying a battery condition of each of the electronic door locks.

21. The system as recited in claim 13, further comprising the steps of:

communicating with a first electronic door lock; and

canceling a key which previously unlocked the first electronic door lock.

22. The system as recited in claim 13, wherein said step (b) further comprising the steps of:

communicating between each of the plurality of room transceivers and an associated display.
