Alarms

Pre-silencing alarms

This function allows you to pre-silence (audio
pause in advance) potential alarm conditions be-
fore they occur. Pre-silencing allows you to concen-
trate on a procedure without being interrupted by
continuous acoustic alarm signals arising from po-
tential alarm conditions. A pre-silence period lasts
two minutes.
Pre-silencing alarms has the following effect:
– Any alarm conditions are reported visually by a
corresponding alarm message and a blinking
parameter box (see page 87).
– A single alarm tone sequence is generated for
the first occurrence of an alarm condition of low,
medium or high priority.
– The alarm message ? Audio paused appears
in the far right field of the header bar along with
a countdown timer and the following symbol:
– If multiple alarm conditions arise during an ac-
tive pre-silence period, the M540 triggers a sin-
gle alarm tone sequence for the highest-grade
alarm event.
NOTE
Pre-silencing alarms is not possible when the qui-
et mode is deactivated.

– From an M540 in standalone mode or on wire-
less transport

an IACS configuration
