SITE BASED CLUSTERED ANTI-PASS BACK SECURITY SYSTEM AND METHOD

摘要

Site based clustered APB security systems and methods are provided. Some systems can include a first plurality of access controllers located at a first site, a second plurality of access controllers located at a second site, and a host system supporting each of the first and second plurality of access controllers. A triggering event at a first of the first plurality of access controllers can cause the first of the first plurality of access controllers to transmit a triggering signal to the host system. Responsive thereto, the host system can identify the remaining access controllers in the first plurality of access controllers, transmit a status update to the remaining access controllers in the first plurality of access controllers, and avoid transmitting the status update to the second plurality of access controllers.

1. A system comprising:
a plurality of access controllers, wherein each of the plurality of access controllers is located at one of a plurality of sites; and a host system supporting each of the plurality of access controllers, wherein a triggering event at a first of the plurality of access controllers causes the first of the plurality of access controllers to transmit a triggering signal to the host system, wherein the host system receiving the triggering signal causes the host system to determine a sub-set of the plurality of access controllers associated with a first site of the plurality of sites at which the first of the plurality of access controllers is located, wherein the host system receiving the triggering signal causes the host system to transmit a status update to the sub-set of the plurality of access controllers, and wherein the host system receiving the triggering signal causes the host system to avoid transmitting the status update to access controllers outside of the sub-set of the plurality of access controllers and not associated with the first site of the plurality of sites.
