Abstract:
1. An RF access control system comprising: an access control panel; a panel interface module in electrical communication with the access control panel via a first communication link to deliver an access signal to the access control panel; an access point operable to read an access signal generated at an access point location; an access point module positioned adjacent the access point in electrical communication with the access point via a second communication link to receive the access signal from the access point, the access point module including an access reader to read the access signal from the access point, and an access processor in electrical communication with the access reader and in communication with the panel interface module to deliver the access signal to the access control panel; a locking control unit in communication with the access control panel to receive a locking control signal, the locking control unit coupled to and in communication with the access point to deliver the locking control signal to the access point; and an electronic locking subsystem positioned at the access point and in communication with the locking control unit to receive the locking control signal, the electronic locking subsystem including a piezo-electric lock having a piezo-electric element, a positional displacement amplifier, a bolt movable between a first position and a second position, and a power supply in communication with the piezo-electric lock to selectively apply a voltage across the piezo-electric lock to move the bolt between the first position and the second position in response to the locking control signal from the locking control unit.
