Open Protocol
Systems
To address the issue of interoperability between control devices in
buildings, an "open" communication protocol has been developed as an
industry standard allowing control devices from different manufacturers
to be used together in the same system. BACnet, the ANSI standard, is
currently supported by most building automation equipment manufacturers.
Synergy
is the first lighting control system to be designed from the ground up
around the BACnet protocol. As a result, Synergy lighting controls can
seamlessly interoperate with most popular building automation systems.
Relays, dimmers, switches, photocells and occupancy sensors are all
network-visible as "points" and can be mapped into the BAS workstation
logic.
Because
BACnet is native to the operation of Synergy controls, the system can
function optimally as a lighting control system, yet still share status
and control with the BAS. This seamless integration is unencumbered by
the restraints imposed by "gate-way" devices often used to interface
lighting to building automation systems.

Building-Wide Integration
An occupancy sensor turns on lighting in an area in response to someone
entering. The change in lighting status causes the HVAC system to open a
damper and adjust other parameters necessary to provide conditioned air to
the space. A lighting icon on the BMS workstation screen changes color to
show the change in status.The
operation manager controls and monitors the HVAC, fire protection, access
and lighting controls throughout the building on a single workstation from
his desk. The Synergy system performs sophisticated lighting control
functions on its own, while seamlessly sharing data and inter-operating with
the other building systems.
All this is made possible because the
controls in the building, including the lighting, are interconnected using
the ANSI standard BACnet communication protocol. |
