alarm-NumericChangeOfStateAlarmExt

This extension implements a change of state alarm detection algorithm for numeric objects. Each algorithm instance defines a set of numeric values that should be considered offnormal conditions and, therefore, should generate an alarm. This alarm extension is available in the Extensions folder of the alarm palette.

It raises an alarm if the floating-point out-value rounded towards zero is equal to any of the specified alarm values. This is useful when Niagara numeric points are exported as Integer or Positive Integer BACnet objects. The intrinsic algorithms for these objects are out of range, which means that you must handle the numeric change-of-state through event enrollment objects.
