ICL+R = Current sourced through current limit and pull up resistor
IAV = Current available to detectors with EOLR fitted
IAV = ICL+R - IEOLR

AZC CURRENT VS VOLTAGE MODE 2 (HIGH CURRENT)
A short circuit at the end of an 800 Ohm line will give a B2 (Detector Operated) alarm.
A short circuit at the end of a 2k Ohm line will give a B3 (programmable) condition.
