TCX850 Series Controllers
The TCX850 series includes the TCX850, TCX851, TCX852, TCX853,
and TCX855 controllers. The TCX850 series controllers are used to
control small pieces of equipment that require fewer I/O points than an
SCX920S, such as VAV boxes or stairwell fans. The TCX850 series
communicates with the CX9200, as well as other Infinet controllers, via
the Infinet network. The TCX850 series can be used in a dedicated or a
non-dedicated smoke control application.
