- If longer times are necessary please
use a time relay like a staircase light
controller.
IMPORTANT!
The a/b switching modules need
for a smooth operation a very
low standby
connecting an electronic door
bell or a staircase light controller
with a high internal resistance
that modules may not work
correctly.
- For this case every a/b switching
module comes
resistor which can be connected to the
electronic door bell or a staircase light
controller to guarantee
standby current for the feeding of the
module..

Alternatively to the door bell buttons you
can use the switching frequencies 1 to 4
during a door call (e.g. for the switching of
a second staircase light controller).The
control is done with the telephone which
has the door call at that time and is
executed by dialling a certain sequence of
digits.
How to connect this:
1. Connect the a/b switching modules with
the clamps named a and b to the line
between the TFS-Dialog 200 and the
internal analog port.
2. Connect the device which should be
switched and the power supply to the
other two clamps.
