Resolution
The front display uses this blinking pattern to alert the user of alarms. How the alarm functions is based on the priority assigned to that alarm. For example:

  • High priority—if a high priority alarm occurs, the display informs the user in two ways: the LED backlight on the display flashes until the alarm is acknowledge and the alarm icon blinks while the alarm is active.
  • Medium priority—if a medium priority alarm occurs, the alarm icon blinks only while the alarm is active. Once the alarm becomes inactive, the alarm icon stops blinking and remains on the display.
  • Low priority—if a low priority alarm occurs, the alarm icon blinks only while the alarm is active. Once the alarm becomes inactive, the alarm icon disappears from the display.
  • No priority—if an alarm is set up with no priority, no visible representation will appear on the display. Alarms with no priority are not entered in the Alarm Log.
