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.
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.
