You may be able to do some measurement on the zones connected to the Comfort and Slaves (which are analog inputs), but not on the LEMs The A?zz command where zz is the zone number in Hex returns the value of the voltage on the zone terminals eg in Monitor I/O screen > A?08 < A?0860 the reply A?0860 means the analog value at zone 8 is 96 compared to ful scale of 255 (FF) For a double eol zone, the nominal values are Zone Open circuit > C0 hex Zone Open A0 hex Zone Closed 60 hex Zone short circuit <60 hex as the wire resistance increases the zone values would increase so this could be used to determine the "health" of the zone wiring This method cannot be used for LEMs as mentioned
