Latched and Unlatched Alarms

The Avant 9600 allows users to select Unlatched or Latched alarms. Option switch
3, located at the bottom of the Avant 9600 behind the back cover, is used to toggle
between Latched Alarms and Unlatched Alarms modes. Unlatched mode (option
switch 3 in the DOWN position) is the default.
When the Avant 9600 is in Unlatched Alarms mode, the Main Alarm LED and the
indication of the alarm source will flash, and the audible alarm will sound until the
alarm condition is no longer present.
In Latched Alarms mode, the audible and visual alarms will continue to signal even
after the alarm condition is no longer present. Pressing the Alarm Silence button will
clear all latched alarms.
NOTE: Only patient alarms are selectable as latched or unlatched.
Equipment alarms are always unlatched.
