Principle loop resistance
Measurement 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).
Rule:

Switch off the 230 V / 50 Hz of the VS.

Install a-b short-circuit at the VS.

All other devices do not disturb the measurement
and can stay connected.

Measure the loop resistance at the strand at a/b
of the last IS or AS.
8 Ohm:
max. 65 m distance AS-VS on 0.6 mm diameter
max. 115 m distance AS-VS on 0.8 mm diameter
AS Front-door station
VS Power supply and control unit
IS
Indoor station
FE Extended function
