Traditional Audible Alarms (HP/Agilent/Philips/Carenet)
• Red alarms: A high pitched sound is repeated once a second.
• Two-star yellow alarms: A lower pitched sound is repeated every two seconds.
• One-star yellow alarms (arrhythmia alarms): The audible indicator is the same as for yellow alarms,
but of shorter duration.
• INOPs: an INOP tone is repeated every two seconds.
ISO/IEC Standard 9703-2 Audible Alarms
• Red alarms: A high pitched tone is repeated five times, followed by a pause.
• Two-star yellow alarms: A lower pitched tone is repeated three times, followed by a pause.
• One-star yellow alarms (arrhythmia alarms): The audible indicator is the same as for yellow alarms,
but of shorter duration.
• INOPs: a lower pitched tone is repeated twice, followed by a pause.
Changing the Alarm Tone Volume
♦ The alarm volume symbol at the top right of the monitor screen gives you an
indication of the current volume. To change the volume, select the volume symbol
and then select the required volume from the pop-up selection.
♦ If you want to see a numerical indication of the current alarm volume on a scale
from zero to 10, select the Alarm Volume SmartKey. The volume scale pops up.
The current setting is indented. To change the setting, select the required number
on the scale. Any settings that are inactive (“grayed out”) have been disabled in the
monitor’s Configuration Mode.
When the alarm volume is set to zero (off), the alarm volume symbol reflects this. If you
switch the alarm volume off, you will not get any audible indication of alarm conditions.
Minimum Volume for No Central Monitoring INOP
If your monitor is connected to an Information Center, and the connection is interrupted, the INOP
message No Central Monit. will appear within 30 seconds, accompanied by an INOP tone. To
help ensure that this INOP, and any other active alarm, is not overlooked, the INOP and alarm tones
may be configured to have a minimum volume. In this case, INOP and alarm tones will sound even if
the monitor alarm volume is set to zero.
