The OmniCare EVC System utilises a 4-wire plus screen ring
circuit to allow continued operation in the event of a cable break.
Cables are sized according to the number of Remote Units and
the distance between them. The maximum length of cable
between Remote Units, and between the Control Panel and the
first and last Remote Unit on each circuit, must be as follows:
MICC (lightweight) 4-core
MICC (heavyweight) 4-core Distance between units not to exceed 200m.
FP200 1.5mm 4-core
FP Plus 1.5mm 4-core
There are typically 20 -25 Remote Units on each ring.
Distance between units not to exceed 150m.
Distance between units not to exceed 200m.
