For each loop, add the lengths of all the branches
on one loop. This sum cannot exceed 10,000 feet
(12 AWG).
(Branch A)
+ (Branch B)
+ (Branch C)
+ (Branch D)
+ (Branch E)
= 10,000 feet or less
Total length of the communications loop pair cannot
exceed 10,000 feet (12 AWG).

Short the termination point of one branch at a
time and measure DC resistance from the
beginning of the loop to the end of that particular
branch. The total DC resistance from panel to
branch end cannot exceed 40 ohms. Repeat this
procedure for all remaining branches.
For detailed wiring requirements, refer to
Appendix F.
Measure by disconnecting loop out and return at the control
panel, shorting the two leads of communications loop
return, and metering loop out.
For detailed wiring requirements, refer to Appendix F.
