Event Enrollment Alarm Extensions

One of four Event-Enrollment (EE) alarm extensions must be configured in each object instance. The Alarm-Extension property is used to select an extension. Each extension selects one of the four supported BACnet eventing algorithms and enables the properties required to configure the extension. The four extensions include Change-of-State, Out-of-Range, Floating Limit, and Command-Failure.

Extensions are provided to allow event configuration to be edited using the web UI. Once edited a set of alarm extension properties is saved in the object's event-parameters properties.
