Alarm Light

  • Last UpdatedJul 18, 2023
  • 2 minute read

The alarm light object is a text object used to draw the operator’s attention to an alarm that may not have a numerical equivalent (for example, LOW FIRE CHECK).

When the alarm is inactive, the text is barely visible so as to not draw the operator’s attention to the text, but still makes the operator aware that there is an alarm associated with a piece of equipment. If the alarm is triggered, the visibility will be forced to "on".
