TCX840 Series Controllers

The TCX840 series includes the TCX840, TCX843, TCX845, TCX846
controllers. The TCX840 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 TCX840 series communicates
with the CX9200, as well as other Infinet controllers, via the Infinet
network. The TCX840 series can be used in a dedicated or a non-
dedicated smoke control application.
