with drain wire and is supplied and installed in the field. See
Table 5. The system elements are connected to the communi-
cation bus in a daisy chain arrangement. The positive pin of
each system element communication connector must be wired
to the positive pins of the system elements on either side of it.
This is also required for the negative and signal ground pins of
each system element. Wiring connections for CCN should be
made at LVT. See Fig. 18 and consult the CCN Contractor's
Manual for further information.
