Nitrox Attention messages and Alarms
Partial pressure of oxygen reaches limit (->ppO
2
max)
Messages:
If the partial pressure of oxygen reaches the set value, the Ala-
din
®
Air Z Nitrox gives an acoustic warning and the depth indi-
cation is flashing.
Response:
Ascend to a lower depth in order to diminish the danger of
oxygen toxicity. Observe <CNS O
2
%-value> carefully.
<CNS O
2
%-value> reaches 75%
Messages:
An acoustic signal can be heard, the symbol <CNS O
2
LIMIT>
flashes continuously.
Response:
Avoid a further increase by beginning the ascent.
<CNS O
2
%-value> reaches 100%
Oxygen toxicity reaching 100% can lead to dangerous neurological sym-
ptoms.
Messages:
A visual alarm appears and an acoustic warning can be heard
every 4 seconds. The CNS O
2
%-value and its symbol are flas-
hing.
Response:
Ascend immediately until the buzzer stops (ppO
2
is then less
than 0.5 bar).
If the ascent speed is displayed and if the CNS O
2
% value does not increa-
se anymore (due to a lower partial pressure of oxygen), the acoustic war-
ning will be suppressed.
