Access control system and method

A controller unit for an access control system, comprising:

• a base portion having a mounting structure for securing the controller unit to a surface at a location proximate an access control point;
• circuitry defining an access control panel and a request-to-exit motion sensor, the circuitry being secured to the base portion, and the circuitry that defines the access control panel including communication ports for supporting communication with peripheral devices of the access control system;
• and
• a cover portion that is detachably secured to the base portion and that encloses the circuitry defining the access control panel and the request-to-exit motion sensor.

A method for controlling access between a secured side of an access control point and a non-secured side of the access control point, comprising:

• providing a reader on the secured side of the access control point for receiving authentication data from an individual;
• providing a local controller assembly on the non-secured side of the access control point, wherein the local controller assembly comprises an access control panel and a request-to-exit motion sensor housed within a same housing;
• transmitting from the reader to the access control panel a data signal including reader data relating to the authentication data that is received from the individual;
• using the access control panel, determining if the individual is authorized to enter the non-secured side of the access control point based on the reader data;
• and
• when it is determined that the individual is authorized to enter the non-secured side of the access control point, providing a control signal from the access control panel to an electronic lock mechanism of the access control point, the control signal for changing the lock mechanism from a secured condition to a released condition.
