Wireless access control and event controller system
First Claim
1. A demand-based authorization method for controlling access to a plurality of lock mechanisms in a wireless access control system having a central access control system comprising a central access controller and a central wireless communicator, and having a separate remote access control system connected to each of said plurality of lock mechanisms comprising a remote access controller, a remote credential reader and a remote wireless communicator maintained in a standby mode to conserve power until activated, wherein said method comprises the steps of:
- storing a list of valid credentials in a memory at said remote access control system wherein said list is indicative of authorized users;
receiving a credential at said credential reader;
comparing said credential to said list of valid credentials;
authorizing access from said remote access control system if said comparing step is indicative of an authorized user;
activating said remote wireless communicator to initiate a wireless communication between said remote wireless communicator and central wireless communicator when said comparing step is not indicative of an authorized user to obtain an updated list of valid credentials;
re-comparing said credential to said updated list of valid credentials; and
authorizing access if said re-comparing step is indicative of an authorized user.

Abstract
A wireless access control system and method is described which permits wireless communication between a remote access controller and a central access controller on an “on demand” basis. The remote access controller can determine the state of the locking mechanism without communication to the central access controller when a valid access request is presented. However, if an invalid access request is presented, a remote wireless communicator will be placed in its transmission mode to request updated user control data from the central access controller. The remote wireless communicator can also be placed in its transmission mode to request updated user control data from the central access controller by a communication command input at a remote programming mode device.
