Sorry for the late reply, been going through a reorg at work lately and had a bunch of long hours.
The entire point of what I did is so that you can build any trigger you want in Rule Machine. When you see alarm event, start the siren... when you see Alarm off, turn off the siren... I personally do this by syncing Abode to HSM, but assuming you don't use HSM this would be just:
Ignore the text between the parens () as that is simply the last value that was seen in that attribute. My kitchen door is open while I'm enjoying the breeze going through the house 
P.S. I've seen a few different ways Abode displays stuff, depending your version of hub. They are not super consistent, so the best thing to do is to enable debug module, then go generate the events that you want to trigger on and check what you see in the Event Log and/or the debug log.
If you find anything odd, send me Trace-level logs here or in private message. I'm working blind against an undocumented API, so I have to see what it tells you to adjust it.
