occurs. This condition continues until all the causes for an alert are removed or the alert(s) are
acknowledged.
• When multiple alerts are generated simultaneously, and there is no alert acknowledgement, the
audio alarm continues to sound no matter even if an alert condition has gone. Also, the pop-up
remains displayed and the latest alert appears in the pop-up
• When there is no alert acknowledgment, the audio alarm continues until the condition causing
the alert(s) is removed. The pop-up remains displayed.
