Abstract

A system and method for energy saving on access control products is disclosed. An access controller controls access control readers, which in turn enable access to a building and/or interior areas of the building. The access controller can identify the locations of the access control readers relative to the building, such as whether the access control readers are located on the perimeter of the building for controlling access to the building, or whether the access control readers are located within the building for controlling access to interior areas of the building. The access controller can then place one or more of the access control readers into a power saving state without compromising overall building security, such as placing interior access control readers into a power saving state when the building is assessed to be unoccupied.

Claims

1. A security system, comprising:

access control readers controlling access to a building and/or to interior areas of the building; and

an access controller that places the access control readers into power saving state when the building is assessed to be unoccupied,

wherein the building is assessed to be unoccupied in response to the access controller receiving a signal indicating that a security alarm panel is armed.

2. A security system as claimed in claim 1, wherein the access control readers include interior access control readers that control access to the interior areas of the building and perimeter access control readers that control access to the building.

3. A security system as claimed in claim 2, wherein the access controller places only the interior access control readers into power saving state when the building is assessed to be unoccupied.

4. A security system as claimed in claim 1, wherein the building is assessed to be unoccupied by:

the access controller receiving indications that individuals have entered and/or exited the building sent from access control readers, the access controller incrementing an enter count in response to receiving the indication for each individual entering the building and incrementing an exit count in response to receiving the indication for each individual exiting the building; and

the access controller identifying that the enter count and the exit count are equal.

5. A security system as claimed in claim 1, wherein the access controller places the access control readers into power saving state by disabling control lines of the access controller that control and provide power to the access control readers.

6. A security system, comprising:

access control readers controlling access to a building and/or to interior areas of the building; and

an access controller that places the access control readers into power saving state when the building is assessed to be unoccupied; and

wherein the access controller places the access control readers into power saving state by sending a power disabling control signal to a power module that provides power to the access control readers.

7. A security system, comprising:

access control readers controlling access to a building and/or to interior areas of the building; and

an access controller that places the access control readers into power saving state when the building is assessed to be unoccupied; and

wherein the access controller places the access control readers into power saving state by sending a sleep signal over a network to the access control readers.

8. A security system, comprising:

access control readers controlling access to a building and/or to interior areas of the building; and

an access controller that places the access control readers into power saving state when the building is assessed to be unoccupied; and

a security alarm panel that receives indications of intrusions at the building from security devices and that sends alarm signals in response, wherein the access controller places the access control readers out of power saving state in response to the access controller receiving the alarm signals.

9. A security system, comprising:

access control readers controlling access to a building and/or to interior areas of the building;

an access controller that places the access control readers into power saving state when the building is assessed to be unoccupied; and

a security alarm panel that sends a signal indicating that the security system is disarmed, wherein the access controller places the access control readers out of power saving state in response to the access controller receiving the disarm signal.

10. A method for a security system, the method comprising:

access control readers controlling access to a building and/or to interior areas of the building; and

an access controller placing the access control readers into power saving state when the building is assessed to be unoccupied, wherein the building is assessed to be unoccupied in response to the access controller receiving a signal indicating that the security system is armed.

11. A method as claimed in claim 10, wherein the access control readers include interior access control readers controlling access to the interior areas of the building and perimeter access control readers controlling access to the building.

12. A method as claimed in claim 11, further comprising the access controller placing only the interior access control readers into power saving state when the building is assessed to be unoccupied.

13. A method as claimed in claim 10, wherein the building is assessed to be unoccupied by:

the access controller receiving indications that individuals have entered and/or exited the building sent from access control readers that control access to the building, the access controller incrementing an enter count in response to receiving the indication for each individual entering the building and incrementing an exit count in response to receiving the indication for each individual exiting the building; and

the access controller identifying that the enter count and the exit count are equal.

14. A method as claimed in claim 10, further comprising the access controller disabling control lines that control and provide power to the access control readers.

15. A method as claimed in claim 10, further comprising the access controller sending a power disabling control signal to a power module that provides power to the access control readers.

16. A method as claimed in claim 10, further comprising the access controller sending a sleep signal over a network to the access control readers.

17. A method as claimed in claim 10, further comprising the access controller placing the access control readers out of power saving state in response to the access controller receiving an alarm signal sent from a security alarm panel, wherein the alarm signal is sent in response to an indication of intrusion at the building.

18. A method as claimed in claim 10, further comprising the access controller placing the access control readers out of power saving state in response to the access controller receiving a signal sent from a security alarm panel indicating that the security system is disarmed.
