DALLAS--The American Society of Heating, Refrigerating and Air-Conditioning Engineers this week released for publication for public review a set of proposals that add physical access control to the existing standards for building automation and control. Upon approval, the new access control standards will be integrated into BACnet (also known as ANSI/ASHRAE 135-2004), a data communication protocol for building automation and control networks. According to ASHRAE, it is an American national standard, a European pre-standard, a Japanese standard, a Chinese standard and an ISO global standard.
The access control standards came out of the Life Safety and Security Working Group, convened by David Ritter, access control project manager at Delta Controls. The group developed eight specific proposals for the following pieces of an access control system: access door object, access point object, access zone object, access user object, access credential object, access rights object, authentication factor input object and the access event algorithm. The proposals are posted at and input from the security industry and members of the installation community as a whole are welcome and expected.
It is ASHRAE's belief that, once approved, these will represent the first comprehensive access control standards.
