Principle loop resistance
Measure loop resistance
None of the devices (AS, IS or FE)
should be further 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
measurement & can stay connected
Measure the resistance at a/b at the
last IS or AS
20 Ohm:
max. 160 m distance AS/IS-VS at
0.6 mm diameter
max. 300 m distance AS/IS-VS at
0.8 mm diameter
AS front-door station
VS power supply and control unit
IS indoor station
FE extended function
short-circuit
a, b here
