Total length of the communications loop pair cannot exceed 10,000 feet
(measured from the control panel out, and back to the control panel).
The DC resistance of the communications loop pair cannot exceed
40 ohms. This measurement may be modeled by disconnecting loop out
and return at the control panel, shorting the two leads of communications
loop return together and metering loop out.
