Abstract
A modular door access control system incorporates a plurality of wireless door modules. Access request signals are transmitted to a remote access control unit. The control unit transmits access authorizing control signals to a respective one of the modules. A newly installed module, in a selected mode, enters into communication with the unit. The unit in turn transmits an identifier to the module for use in identifying itself to the unit subsequently in response to a received access request.
