NetSure 531 AC1 Power Supply System User Manual
Observation: When this type of alarm is raised, the system maintains normal output for a while. If the alarm occurs
during watch time, it should be handled immediately. If the alarm occurs during non- watch- time, handle it during
watch time. The alarm indicators will be on when observation alarm occurs.
No alarm: The system will not generate a visible or audible indication.
The alarm default value of the controller is listed in Table 4-5.
