7.1.3 Stage selection by reverse polarity (TAR) - all DC versions (except option –SSM)
Note: Only applicable to DC version!
Not applicable to –SSM versions!
The control inputs C1 and C2 must not be connected on the connection board!
Switch setting should be as follows:
 S1A to
(diode bridged)
 and changeover switch S1B to "+"
Tone "C1+C2" can also be selected by reversing the polarity of the operating voltage to the basic tone (♪):
8. Option
–SSM (soft-start module, only 24V DC)
The inrush current peak is limited to:
: max. 2.1 A
The operating voltage is only switched through to the operating equipment from >7 V.
Operating voltage range: 18 V – 30 V DC
Positioning of the resistor (1kOhm) is as follows:
 Always mount the resistor for line monitoring in the last device.
 See below for the position of the second resistor if the sounder and flashing light are connected separately.
 Remove any resistors that are not required.
Common connection of sounder and flashing light:
Separate connection of sounder and flashing light:
