ABSTRACT:
A system for securing a complex with a plurality of lockable access points has a stand-alone keypad-operated remote station at each access point for communication with a desk station through a local area network. In a preferred embodiment the access points are room doors of a hotel or an apartment building and the rooms are divided into groups having separate controllers to relay messages between stations and perform control functions. The desk station then has a keypad for entry of access code information chosen by a guest and a separate keyboard for assignment of a room number by a clerk. The desk station stores the access code at a remote station located at the assigned room, whereupon the room can be unlocked only by manual entry of the code on a keypad of the remote station. Each remote station functions independently to open a door associated with it and remains operable to open the door even if other portions of the system malfunction.
