Abstract

An exemplary method includes operating an access control device in a standalone mode, which involves controlling a locked/unlocked state of the access control device locally, and operating a wireless transceiver of the access control device in a lower-power state in which the wireless transceiver is operable to receive a lockdown signal from an external device. The method further includes operating the access control device in a networked lockdown mode in response to receiving the lockdown signal from the external device. Operating the access control device in the networked lockdown mode involves placing the access control device in a locked state, establishing a wireless communication connection with the external device via the wireless transceiver while operating the wireless transceiver in a higher-power state.

First claim

What is claimed is:

1. An access control device, comprising:
a locking member operable to move between a locking position and an unlocking position to adjust a locked/unlocked state of the access control device;
a lock state selector operable to cause the locking member to move between the locking position and the unlocking position to thereby adjust the locked/unlocked state between a locked state and an unlocked state;
an electronic actuator configured to drive the locking member from the unlocking position to the locking position in response to receiving a lock signal;
a controller in communication with the actuator and configured to transmit the lock signal in response to receiving a lockdown command; and
a wireless transceiver in communication with the controller and configured to selectively establish a wireless communication connection with an external device, the wireless transceiver having a higher-power mode in which the wireless communication connection is established, the wireless transceiver having a lower-power mode in which the wireless communication connection is not established, wherein the wireless transceiver is operable to receive the lockdown command from the external device while operating in the lower-power mode;
wherein the access control device has a standalone mode in which the access control device operates the wireless transceiver in the lower-power mode and the locked/unlocked state of the access control device is controlled locally;
wherein the access control device has a networked mode in which the access control device operates the wireless transceiver in the higher-power mode and communicates with the external device via the wireless communication connection;
wherein the access control device is configured to remain in the standalone mode in response to operation of the lock state selector;
wherein the access control device is configured to transition from the standalone mode to the networked mode in response to receiving the lockdown command; and
wherein with the access control device operating in the networked mode, the controller is further configured to transmit the lockdown command to a second external device via the wireless transceiver.

2. The access control device of claim 1 , further comprising a user-operable lockdown device configured to transmit the lockdown command when operated by a user.

3. The access control device of claim 1 , wherein the wireless transceiver comprises a Bluetooth transceiver having an active mode corresponding to the higher-power mode and a sleep mode corresponding to the lower-power mode; and
wherein the Bluetooth transceiver is operable to receive the lockdown command from the external device while operating in the sleep mode when paired with the external device.

4. The access control device of claim 1 , wherein the wireless transceiver comprises a lower-power transceiver that is active in the lower-power mode and a higher-power transceiver that is active in the higher-power mode.

5. The access control device of claim 1 , wherein the electronic actuator is further configured to drive the locking member from the locking position to the unlocking position in response to an unlock signal;
wherein the controller is configured to transmit the unlock signal in response to operation of the lock state selector in a first manner; and
wherein the controller is configured to transmit the lock signal in response to operation of the lock state selector in a second manner.

6. The access control device of claim 1 , wherein the controller is further configured to establish, via the wireless transceiver, a second wireless communication connection to a second external device when the access control device is operating in the networked mode.

7. An access control device having a locked/unlocked state, the access control device comprising:
a wireless transceiver;
a control assembly in communication with the wireless transceiver; and
one or more non-transitory computer readable media connected with the control assembly and comprising instructions which, when executed by the control assembly, cause the access control device to:
selectively operate in a standalone mode, wherein to operate in the standalone mode comprises to permit local adjustment of the locked/unlocked state at the access control device; and
selectively operate in a lockdown mode in response to receiving a first lockdown command, wherein to operate in the lockdown mode comprises to retain the locked/unlocked state as a locked state;

wherein the first lockdown command is received from a first external device; and
wherein to operate in the lockdown mode further comprises to transmit, via the wireless transceiver and to a second external device, a second lockdown command.

8. The access control device of claim 7 , wherein the second lockdown command is configured to cause a second access control device to operate in the lockdown mode.

9. The access control device of claim 7 , further comprising a lock state selector operable to adjust the locked/unlocked state when the access control device is operating in the standalone mode; and
wherein the lock state selector is inoperable to adjust the locked/unlocked state when the access control device is operating in the lockdown mode.

10. The access control device of claim 7 , wherein the wireless transceiver is configured to selectively establish a wireless communication connection with the first external device;
wherein the wireless transceiver has a higher-power mode in which the wireless communication connection is established;
wherein the wireless transceiver has a lower-power mode in which the wireless communication connection is not established; and
wherein the wireless transceiver is operable to receive the first lockdown command from the first external device while operating in the lower-power mode.

11. The access control device of claim 10 , wherein the wireless transceiver comprises a Bluetooth transceiver having an active mode corresponding to the higher-power mode and a sleep mode corresponding to the lower-power mode; and
wherein the Bluetooth transceiver is operable to receive the first lockdown command from the first external device while operating in the sleep mode when paired with the first external device.

12. The access control device of claim 10 , wherein the wireless transceiver comprises a lower-power transceiver that is active in the lower-power mode and a higher-power transceiver that is active in the higher-power mode.

13. An access control device having a locked/unlocked state, the access control device comprising:
a wireless transceiver;
a control assembly in communication with the wireless transceiver; and
one or more non-transitory computer readable media comprising instructions which, when executed by the control assembly, cause the access control device to:
selectively operate in a standalone mode, wherein to operate in the standalone mode comprises to permit local adjustment of the locked/unlocked state at the access control device; and
selectively operate in a networked mode in response to receiving a first command, wherein to operate in the networked mode comprises to adjust the locked/unlocked state based upon information received via the wireless transceiver;

wherein the first command is received from a first external device;
wherein to operate in the networked mode further comprises to transmit a second command to a second external device; and
wherein the second command is configured to cause a second access control device to operate in the networked mode.

14. The access control device of claim 13 , wherein
