I have one controlling my kitchen light and I can't sneak past it, not even to grab a beer out of the fridge.
By using (more or less) the default configuration you should be able to get BASIC ON/OFF command frames from your 'sensor device' (idx 150 on your screenshot), burglar/alarm will likely be getting OFF commands mostly (that's technically not correct, but let's not go there in this post).
Try adding a light/switch to group 1 (I think that group gets the basic commands by default...), and it should be able to turn it on then off after a while.
If it doesn't work, you might have changed some settings - try reverting a few params back to their defaults:
Set param 1 to 10 (default motion sensitivity - or close enough), param 8 to 0 (pir always active!)
Param 12 to 0 (to get basic on/off sent to group 1), param 14 to 255, param 16 to 0 (simple switches&lights will interpret 255 as 'on' and 0 as 'off')
That should detect you... unless you're a ghost or have the same body temperature as a brick wall
If you're really after the alarm stuff, I'm afraid I can't be much help there.
But unless you have smoke-, co2-, water-detectors and want to determine exactly what type of alarm it is, and handle it accordingly - you should be all set! ...it will still detect a non-smoking burglar!
