Physical Access Control with BACnet White Paper
David Ritter, Huixin He · 2008
This document outlines the use of existing definitions of as well as extensions to ANSI/ASHRAE 135-2004 BACnet to enable the implementation of and interfacing to Physical Access Control Systems using the BACnet data model and services. The extensions shall enable inter-domain interoperability and common user interfaces. They also enable the construction of Physical Access Control Systems containing devices of different product vendors and product generations. The extensions include new object types, alarming and logging. This document represents the ongoing work of the SSPC135 LSS-Working Group, and the basis for proposed changes to the BACnet standard. The contents are subject to change. It is anticipated that some content of the document will become an informative Annex to the BACnet Standard.
