Run 2 conductor #18AWG (common), 4 conductor
#22AWG (common), RG59/U (common) and 1 conduc-
tor #22AWG (selective) cable from video monitor+handset
to video monitor+handset to the central equipment location
(where the VCU6 unit is found). Additional cables may be
used to serve other monitors on other risers (lines). Cables
may be straight or twisted pair type and may be solid or
stranded conductors. Depending upon additional system
options and/or functions you may need to run additional
wires. Please consult the factory for more information.
RG59/U coax cable must be good quality, ALL COPPER,
with minimum 95% copper braiding. As with all systems,
we recommend running some spare wires, for future use.
Route cable away from AC power wiring, transformers,
fluorescent lights, light dimmers or other electrical de-
vices. Protect cable from damage. Shielded cable should
