For applications which require more tones than just the base tone, it is possible to provide up to three additional tone
types with the use of the following electrical controls.
As a basic rule, the desired base tone (♪, see tone table in the appendix) is set with the tone selector switch S3 on the
driver board. The corresponding additional tones (C1, C2, C1+C2) can be gathered from the table "Selection of the
tones".
DC-Version:
When used with correct polarity, the tone selection
takes place through the control inputs C1 and C2 on the
circuit board. In the process, the supply voltage must
always be applied together with the two control inputs.
Switch S1 on the driver board is open.
The selection of the polarity of the control voltage ("+" or
"_") takes place with the switch S2 on the driver board.
"+": positive control
"-": negative control (factory setting)
Caution: If the control voltage is greater than the supply
voltage or the supply voltage is not applied, the operat-
ing current supply is provided through the control inputs.
A corresponding load capacity must then be guaran-
teed.
AC-version:
In the AC version the tone selection takes place by
connecting the phase "L" of the supply voltage to the
control inputs C1 and C2. In the process, the supply
voltage must always be applied together with the two
control inputs.
Tone selection with supply through control input (TAV) - for all DC versions
The sounder can be supplied with operating voltage through the control inputs C1 and C2 on the circuit board. Supply
and tone selection thus take place simultaneously.
The minus pole of the sounder must be connected. With connection of the positive voltage to the plus pole of the cir-
cuit board, the base tone (♪) is generated; with connection to C1 or C2 the corresponding tone is selected.
With simultaneous connection of the positive voltage to C1 and C2 the tone "C1+C2" is selected.
The switch S2 on the driver board must be set to "+".

Tone selection through pole reversal (TAR) - for all DC versions except for option -SSM
If the switch S1 on the driver board is closed, the tone "C1+C2" can be selected in addition to the base tone through
pole reversal. The switch S2 must be set to "+".
The control inputs C1 and C2 may not be switched on the circuit board.
