Latching Alarms

The alarm latching setting for your monitor defines how the alarm indicators behave when you do not
acknowledge them. When alarms are set to non-latching, their indicators end when the alarm
condition ends. Switching alarm latching on means that visual and/or audible alarm indications are still
displayed or announced by the monitor after the alarm condition ends. The indication lasts until you
acknowledge the alarm.
