Abstract
An exemplary access control device includes a locking member having a locked position and an unlocked position; an electronic actuator operably connected with the locking member; a switch connected between the electronic actuator and a power supply, the switch having a closed state in which the electronic actuator is connected to the power supply and is operable to maintain the locking member in the unlocked position, the switch having an open state in which the electronic actuator is disconnected from the power supply; and a manual actuator operable to transition the switch between the open state and the closed state.
Claims28
An access control device, comprising:
- a locking member having a locking position and an unlocking position;
- an electronic actuator operably connected with the locking member;
- a switch electrically connected between the electronic actuator and a power supply, the switch having a first switch state in which the electronic actuator is electrically connected to the power supply and is operable to maintain the locking member in the unlocking position, the switch having a second switch state in which the electronic actuator is electrically disconnected from the power supply;
- and
- a manual actuator operable to transition the switch between the first switch state and the second switch state;
- wherein movement of the switch from the first switch state to the second switch state by the manual actuator renders the electronic actuator inoperable to move the locking member.
An access control device, comprising:
- a locking member having a locking position and an unlocking position;
- an electronic actuator operably connected with the locking member and operable to move the locking member from the locking position to the unlocking position;
- an electronic switch operable to selectively electrically connect the electronic actuator with a power supply;
- and
- a manual actuator operable to transition the electronic switch between a first switch state and a second switch state;
- wherein the manual actuator comprises one of a thumbturn or a lock cylinder;
- and
- wherein movement of the electronic switch from the first switch state to the second switch state by the manual actuator renders the electronic actuator inoperable to move the locking member.
An access control device, comprising:
- a locking member having a locking position and an unlocking position;
- an electronic actuator operably connected with the locking member;
- an electronic indicator mechanism operable to electronically indicate a state of the access control device;
- a switch configured for connection with a power supply, the switch having a first state and a second state;
- and
- a manual actuator operable to transition the switch between the first state and the second state;
- wherein, with the switch in the first state, the electronic actuator is connected with the power supply and the electronic indicator mechanism is disconnected from the power supply;
- and
- wherein, with the switch in the second state, the electronic actuator is disconnected from the power supply and the electronic indicator mechanism is connected with the power supply.
