Note:
On any segment of wire protected by one or more I modules, limit the wire
resistance to a maximum value of 1.5 ohms for a given line path. The wire resistance
is measured from the Controller’s port to the furthest appliance in the protected
segment. Deviation from this limitation does not guarantee isolation for short-circuits
that are located greater than 1.5 ohms.
