threshold.
If the monitor is configured for Non-Latching alarms, the CLR button will not appear,
and all alarms will automatically clear when the concentration drops below the alarm
threshold.
Audible Beeper
An audible beeper is sounded when any alarm is activated. A slow beep indicates that
one ore more ‘HI’ alarms has been triggered, and a fast beep indicates that one or more
‘HI-HI’ alarms has been triggered. Pressing the BEEP button from the alarm menu will
silence the audible beeper for 5 minutes. Note: Pressing the BEEP button does not clear
any of the alarms, it simply silences the audible alarm. If the alarms are not cleared, the
audible alarm will automatically resume in 5 minutes.
See Sections 3.2 and 3.6 for details on configuring concentration alarms.
