6.2 Alarm types
Type 1: Ventilation monitoring alarms
If two alarms with different priority levels are triggered at the same time, the higher priority alarm
takes precedence over the lower priority alarm. If two alarms with the same priority level are
triggered at the same time, refer to the table under the heading “Relative alarm priorities” on
page 73.
Note:
The ‘Trigger threshold [can be stopped?]’ column in the following table indicates for each
alarm whether it can be stopped permanently (YES), stopped temporarily (2 min) or not stopped
at all (NO).
