Abstract

See full text

An access control device generally includes an electromechanical actuator operable to transition the access control device between a locked state and an unlocked state, an energy storage device operable to store electrical power from a power supply, and control circuitry. The control circuitry is configured to direct a first electrical power from the energy storage device to the electromechanical actuator in response to one or more first criteria. In a fail secure mode, the first electrical power is configured to cause the electromechanical actuator to transition the access control device to the locked state. In a fail safe mode, the first electrical power is configured to cause the electromechanical actuator to transition the access control device to the unlocked state. Certain embodiments further include a user-adjustable switch operable to transition the control circuitry between the fail secure mode and the fail safe mode.
