Once you have configured your subscriptions, the AlarmWorX Multimedia Server will receive all alarms subscribed to in the configuration database. Alarm filters allow you to filter an alarm subset. You can make filters that only filter a specific alarm tag or filters that filter a group of alarms. The Multimedia Server uses alarm filters to specify which subset of alarms will be used to initiate a multimedia action.
The default configuration database provided in the installation contains many configured alarm filters. To view these filters, expand the Alarm Inputs folder in the tree control, and then expand the Alarm Filters folder. This shows all of the filters already defined in your system.
Create a New Alarm Filter:
Expand the Alarm Inputs folder and right-click Alarm Filters. Select 
Alarm Filter. The Multimedia Alarm Filter form displays.
Enter a name in the Filter Name: box.
Create the Filter by clicking the Edit Filter button or click in the Filter String box and type the filter string. You can use the Expression editor to assist you in writing an filter expression. For more information, refer to Expression Editor.
