Configuration
The diagram below provides an example of how an alarm state can be deemed ‘Normal’ or ‘Critical’. The example shows the
value thresholds for the normal and critical state of the DC supply in a QB. Once a DC supply measurement is taken, the
behavior of the alarm state reporting structure is as follows:
Normal: If the value falls within the green zone (11 to 30 VDC) the alarm state can display ‘normal’ as this is an acceptable
operating value.
Critical: If the value falls within the red zone (below 11 VDC or above 30 VDC) the alarm state can display ‘critical’ as these
values are the hardware limits of the radio (the radio may switch off or self protect depending on the extremity of the critical
value).
Warning State
Enable/Disable the warning state for the respective alarm being configured. The warning state can help prevent a critical
alarm from occurring, by indicating an alarm value has been measured outside of ‘normal’ operating conditions, but, still
within ‘critical’ operating conditions. This means a warning alarm can be active, before a critical alarm state is reached.
Once the warning alarm is enabled, a limit/threshold should be configured. The diagram below provides an example of how
the warning alarm is implemented into the alarm state reporting structure for the DC supply in a QB. Once a DC supply
measurement is taken, the behavior of the alarm state reporting structure is as follows:
Normal: If the value falls within the green zone (12 to 28 V) the alarm state can display ‘normal’ as this is an acceptable
operating value.
Warning: If the value falls within the amber zone (11 to 12 V OR 28 to 30V) the alarm state can display ‘warning’ as this is
has been configured by the user to be outside of normal operating conditions.
Critical: If the value falls within the red zone (below 11 V or above 30 V) the alarm state can display ‘critical’ as these values
are the hardware limits of the radio (the radio may switch off or self protect depending on the extremity of the critical
value).
