R
ESISTANCE VALUES
The maximum length cable length between the Control Panel and
the First Remote Unit, or between each Remote Unit must not
exceed the following distances unless a Repeater Unit is used.
The following table states nominal resistance values for the
different types of cable normally encountered.
Table A.1 — Resistance Values for Different Cable Types
MICC (lightweight) 4-core Distance between units not to exceed 150m.
MICC (heavyweight) 4-core Distance between units not to exceed 200m.
FP200 4-core Distance between units not to exceed 200m.
FP Plus 4-core Distance between units not to exceed 200m.
