This should do it.
WHEN Front Door Sensor NOT READY
THEN SAY FRONT DOOR IS OPEN
The phrase "FRONT DOOR IS OPEN" is a custom message. Meaning you have to put the text into one of the message slots. Look for "Messages" in the Setup tree on the left had side of the PCAccess window and form your sentences from the list of words built in to the controller. You can construct a sentence up to six words long. Also, I read somewhere that you can record your own message. However, it would be your voice and not that of the controller. I've not tried it though so your mileage may vary..Hope this helps..
