Installation
Control with a/b switching modules
Setting switching frequencies
The switching frequency is set via the DIL switch on the a/b switching
module.
Connecting the ringer, door opener and stair light timer
Important:
An a/b switching module can only maintain a switching
operation for 0.5 to 4.5 seconds.
–
If a switching operation needs to last longer, use a time relay such as
a stair light timer.
Important:
The a/b switching modules only need a very low
quiescent current for problem-free operation. If an electronic ringer or an
electronic stair light timer with a high internal resistance is connected, it
is possible that the a/b switching module will not function correctly.
–
Each a/b switching module is supplied with an additional resistor to
resolve this problem. Connect this resistor to the terminal clamps on
the electronic ringer or electronic stair light timer. This ensures that a
minimal quiescent current is provided for the a/b switching module.
