Principle loop resistance
Measure loop resistance
None of the devices (AS, IS or FE) should be fur-
ther than 20 Ohm away from the power supply and
control unit (VS).
Switch OFF the 230 V / 50 Hz of the VS.
Install a-b short-circuit at the VS.
Other devices are not disturbing the measure-
ment, they can stay connected.
Measure the resistance at a/b at the last IS or AS.
8 Ohm:
max. 62 m distance AS/IS-VS by 0.6 mm diameter
max. 112 m distance AS/IS-VS by 0.8 mm diameter
AS front-door station
VS power supply and control unit
IS
indoor station
FE
extended function
