The alarm annunciator unit is a very flexible
device but at the same time easy to use.
The programming work is carried out easily by
means of the programming push-buttons on the
front panel or via the serial communication
using e.g. the SMS 010 setting and monitoring
software. The parameter values are stored in a
non-volatile EEPROM memory which means
that the parameter programming is a very straight
forward action and that the information con-
tent of the memory is maintained even in a loss
of supply situation.
The annunciator unit is programmed by means
of the five push-buttons and the four digit
display on the front panel. The push-buttons are

The parameter values can be and are usually
finally defined after that the annunciator unit
has been mounted at site during the commis-
sioning work.
By means of a plug selector located on the PCB
just behind the front panel the switching over of
the annunciator unit into the programming
mode can be prohibited. In this way the pro-
gram memory of the annunciator unit can be
protected against unauthorized access.
