Auris 2014 Toyota Tilt Alarm

So I've just gotten the new Toyota tilt alarm for my Auris 2014, though, there was no technical adviser to actually demonstrate or instruct how to use or disable it etc, so wondered if anyone else has had the Toyota tilt alarm fitted that might know more about it? 

I tested by locking the car, and jacking it up, it does indeed go off, but unlocking via the keyfob doesn't actually stop the alarm, unless there's some delay as it stopped 5 seconds or so later, though triggered once again, although the car was still half jacked at that point but unlocked via the keyfob, again, repeated pressing the unlock button didn't seem to kill the alarm instantly. 

Wondering if this is normal. The instructions to disarm/rearm the alarm pretty much suck with no clear indication of whether the code you entered worked or not.
