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.
