Abstract: A system for distributing a license key for upgrading an access control system. A portable token that includes first and second identifiers, such as a visible serial number and a concealed control number that can be derived from the serial number. The access control system is identified by a third identifier, such as a MAC address. A license server generates a license key from the first, second and third identifiers that is operative to allow access to software features that are resident on the access control system without the need for an Internet connection.

Abstract: A method, system and apparatus for operating a safety sensitive edge for the safeguarded motor-driven movement of a door or gate having a moving edge is provided. An external sensing device(s) arranged in a feedback loop is disposed proximate the moving edge of the door and generates a fault signal when an obstruction is detected or when components of the feedback loop have systemically failed. A user indicates a desire to move the door by selecting a button, which generates a depressed signal while the button is depressed. The status of these signals is provided to a controller. In the absence of the fault signal, the controller generates an output signal indicating safe movement of the door is possible. If the fault signal is present, the controller generates an output signal indicating safe movement of the door is possible when the depressed signal is provided to the controller.
