6. Audible and Visual Indicators
The concentrator has an audible alarm and three visual indicators
(green, yellow and blue).
Notifications
The concentrator monitors various parameters during operation and utilizes
an intelligent alarm system to indicate a malfunction of the concentrator.
Mathematical algorithms and time delays are used to reduce the probability
of false alarms while still ensuring proper notification of an alarm condition
If multiple alarm conditions are detected, the highest priority alarm will be
displayed.
To insure that audible notifications may be heard, the operators position must
be determined to suit the surrounding noise level.
Note that failure to respond to the cause of an alarm condition for low, medium
and high priority alarms potentially will result in discomfort or reversible minor
injury only and develop within a period of time sufficient to switch to a backup
source of oxygen.
The following notification messages are accompanied by an audible and/or
visual indicator.
