The following table provides examples of filters used by DDAs for routing event messages.

Table 1. Filtering Examples

Example

Meaning

Authorization Category != HVAC

The DDA routes all event messages to the defined destination except those from the HVAC category.

Acknowledge Required == true

The DDA routes only the event messages that require acknowledgment to the defined destination.

Current Status == Alarm

The DDA routes all event messages that were generated by objects in Alarm status to the defined destination.

Previous Status != Unknown Previous State

The DDA routes all event messages to the defined destination except those that were generated by objects in the unknown previous state.

Priority <= 200

The DDA routes all event messages with an Event Priority equal to or less than 200 to the defined destination. See Event Priority.

Start Day of Week >= Friday

and

Start Time >= 05:00:00 PM

and

End Day of Week <= Monday

and

End Time <= 06:00:00 AM

The DDA routes all event messages generated from 5:00:00 PM on Friday through 6:00:00 AM on Monday.

The Time format is defined by the Language selected in the User Profile (User Profile tab of the Security Administrator System).

Applying Multiple Filters Example:

If you define multiple filters for a destination, the DDA combines all the criteria with an AND condition (all filter criteria must be met).

If you want to define a set of filters for sending all High Alarm messages for your HVAC systems that have been defined with event priorities belonging to the Property Safety Group (Priority 40–79) and require acknowledgment at an email destination, apply all the following filters under the Email tab of the Engine.

  • Authorization Category == HVAC

  • Current Status == High Alarm

  • Priority >= 40

  • Priority <= 79

  • Acknowledge Required == true
