Item Value Description
Emergency mode
Disable calls below priority
level
Selection
(prio. 0‑224)
Announcements with a priority lower than
the selected priority are aborted when
running and not started when started if the
system is in the emergency mode. The system
is automatically set to emergency mode when
an emergency announcement is started.
Backup power mode
Disable calls below priority
level
Selection
(prio. 0‑255)
BGM and announcements with a priority
lower than the selected priority are aborted
when running and not started when started if
the system is in the Backup power mode. Use
the Backup power mode action to put the
complete system in the backup power mode.
Individual amplifiers go to backup power
mode if the power supply of that device
disappears. Then BGM and announcements
with a priority lower than the specified
priority are only routed to amplifiers (zones)
that are not in backup power mode.
Report mains supply fault Enable / Disable Enable: Reports the external mains failure
that comes from the control input of the MPS
("Mains supply fault: External" ). See
Multifunction power supply, page 53 ,
Optional: Using the Logging Viewer, page 125
and/or Event messages, page 134 .
In some cases the Backup power mode is
enforced, for instance by a control input
action, to save power and not because of a
fault. The fault reporting can be disabled
here.
