3.7.3.3 DUPF1 alarm interface
The DUPF1 provides a cable with a 4x2 way Molex connector for its alarm
signals. The DUPF1 alarms are connected to one of the 3 alarm interfaces
F3, F4, F5 on the FAMO1 or FAMO1-F, normally to the F5 interface. The
DUPF1 connects to the highest 2 inputs of the 4 alarm inputs provided via
the Molex connector:
The DUPF1 alarm outputs are implemented as “breaking” contacts, i.e. the
alarm signals provide ground potential if the alarm is inactive.
