Description: The lower 32 bits of the absolute value for threshold for the sampled statistic. The actual threshold value is determined by the associated instances of the hcAlarmFallingThreshAbsValueHi and hcAlarmFallingThresholdValStatus objects, as follows:

ABS(threshold) = hcAlarmFallingThreshAbsValueLo + (hcAlarmFallingThreshAbsValueHi * 2^^32)

The absolute value of the threshold is adjusted as required, as described in the HcValueStatus textual convention. These three object instances are conceptually combined to represent the falling threshold for this entry.

When the current sampled value is less than or equal to this threshold, and the value at the last sampling interval was greater than this threshold, a single event will be generated. A single event will also be generated if the first sample after this entry becomes valid is less than or equal to this threshold and the associated hcAlarmStartupAlarm is equal to fallingAlarm(2) or risingOrFallingAlarm(3).

After a falling event is generated, another such event will not be generated until the sampled value rises above this threshold and reaches the threshold identified by the hcAlarmRisingThreshAbsValueLo, hcAlarmRisingThreshAbsValueHi, and hcAlarmRisingThresholdValStatus objects.

This object may not be modified if the associated hcAlarmStatus object is equal to active(1).
