Application Example
Task: In a chemical factory, eight laboratories are to be provided with alarm switches. Upon activation
of an alarm button, the fire staff of the factory is informed via a siren. When the fire staff has
acknowledged the alarm, they go to the lab where the alarm was started.
Solution: The alarm switches are coded for channels A1 to A8. The source of the alarm is indicated on a
panel whose LED is activated via a mimic display. The addresses correspond to those of the
alarm contacts. The fire staff uses a button coded for address B1 to acknowledge the alarms.
The alarm is reset through a reset button coded for address B2. The alarm is sounded by
means of a horn activated through a relay output of DSM 8 coded for address B4.
