Set up Text-To-Speech

The trigger must first be configured to execute the Workflow when a door asset has a status change.

1. Create a new Workflow.
2. Configure the trigger.
   1. Double-click the Start block.
   2. Click Add.
   3. Navigate to the integrated system for the doors, expand, and select Assets.
   4. In the Events pane, click Status Changed.
   5. Click OK, then OK again.

The Workflow must be configured so we only announce that there has been a door forced open at the correct time, rather than on just any status change.

1. Add a Logic block to the Workflow.
2. Configure the Logic block.
   1. Double-click the Logic block.
   2. Expand Triggering Item and select Initial.
   3. In the Properties pane, double-click Current Status Name.
   4. In the Operations pane, click =.
   5. In the Constants pane, click String.
   6. In the Expression pane, type "Forced Open" into the text box.
      
   7. Click OK.
3. Add an Action block to the Workflow.
4. Connect the False exit path for the Logic block to the Stop block, and the True exit path to the Action block.
5. Connect the Action block exit path to the Stop block.
   

We now need to configure the actual announcement to tell the operator a door has been forced open.

1. Double-click the Action block.
2. Click Sound Service.
3. In the Commands pane, select one of the text-to-speech commands:
