Adapt Alarm Tables

5 – Adapt Alarm Tables

If third-party BACnet devices are integrated in Desigo CC, the alarm table must be checked in accordance with the alarm priorities of the applicable vendor or adapted where applicable. The changes are made per device (recommended) or data point.

Alarm class	Alarm state	Alarm priority
Fault	fault	not available
Life Safety	not available	0‒31
Property Safety	not available	32‒63
High Priority Alarm	not available	64‒95
Medium Priority Alarm	not available	96‒127
Low Priority Alarm	not available	128‒191

Alarm Table Configurations

The following figure displays how an alarm is configured in the management platform to display in the correct alarm class on the Alarm Overview bar. The example shows the behavior on a data point. The same can be done at the device level.

Alarm Table Standard Configuration
Object	Alarm Setting	Validity Info
Object model	Default	Valid
Device	Alarm table	Valid
Data point instance	Default	Invalid

Check Notification Class

In order to ensure a correct display on the Alarm Overview bar, the notification class must be properly set up in the field network. This has to happen at the individual devices or data point as well as on the notification class (NC) object. The example shows the behavior on a data point. The same can be done at the device level.

There are field networks that automatically calculate the notification class from the alarm function and alarm class. In this case, the notification class cannot be edited on the alarm object. Change the alarm function or alarm class to receive another notification class.

Inheritance Rules for Object Model, Function, and Object
Icon	Color	Description
	White	No value is inherited.
	Gray	The project instance value is inherited.
	Green	The function inherits the value.
	Blue	The object model inherits the value.
	Question mark with a yellow background.	The value is undefined until the instance is saved.

While you change inheritance properties, you cannot disable an inheritance. As a result, the state changes from to or when editing. This display for the inheritance function is used for the Main, Properties, Details, and Alarm Configuration expanders.
