Communication Wiring
Note: Communication link wiring is a
shielded, twisted pair of wire and must
comply with applicable electrical codes.
An optional communication link provides
a serial communication interface (SCI)
between Tracer Summit
®
and each
commercial self-contained (CSC) unit in
the system. The CSC system can have a
maximum of 12 CSC units per connection
link to Summit
®
. Use a single 18 AWG
shielded, twisted pair wire with stranded,
thinned copper conductors to establish
each communication link between
Summit
®
and each unit.
