The auditory signals can be identified by the number of sound impulses of each
burst of impulses. A burst of impulses is a set of sounds that occur periodically and
that can be temporarily and easily identified.

Priority Burst impulses
High 10 (2 x 5)
Medium 3
Low 1
Auditory signals cannot co-exist. Therefore, if several alarms have been triggered,
only the sound that belongs to the higher priority alarm condition is present.
The screen displays text indicating the name of the alarm condition on a colored
background. This color is the same as the one used for light visual signals. That is,
red for high priority and yellow for medium and low priority. This is the name with
which the alarm condition is recorded in the ACTIVATED ALARMS window.
Unlike the visual light signal, these signals make it possible to recognize each
specific alarm condition.
The Inop. Vent. Alarm is the only one that does not have this kind of signal becau-
se when it is triggered, the ventilator becomes inoperative and the screen stops
working.
Once the alarm condition has disappeared, the alarm signals behave differently. When
an alarm condition has stopped and the alarm signals persist, they are called maintai-
ned signals. On the other hand, if the signal ends at the same time as the condition, it
is a non-maintained signal.
If there are one or more maintained signals, the same procedure is always followed to
deactivate that signal or those signals. Press the
[Esc] key.
In iTernIS ADV light alarm signals have maintained signal characteristics. The sig-
nals are maintained with the characteristics indicated on Table 11-4.
Table 11-4 Maintained visual signal - Alarm Signals.
Priority Color Characteristic of the maintained signal
High Red The LED stays on, without flashing
Medium Yellow The LED stays on, without flashing
Low Yellow The LED stays on, without flashing
The upper light indicator does not behave like a maintained alarm signal. Therefo-
re, when the cause of the alarm condition disappears, the indicator turns off.
