Ok so I've done some playing around with the alarm, much to the annoyance of my neighbours on a Sunday afternoon. (especially #9. We'll just call it payback for letting your scabby cat s**t my garden

).
So anyway, the 4 beeps that are heard when you unlock the car are definitely to warn that the alarm has been activated whilst you were away.You should not hear ANY beeps when unlocking the car under normal conditions.
However you will hear the same 4 beeps if you unlock the boot without using the card. I think this is because the internal sensors notice the boot opening but realise its not an attempt at breaking in, so does not go into full alarm mode but just gives these 4 beeps.If you unlock the boot using the card you do not hear the 4 beeps.
If you "double lock" (deadlock), you still wont hear the 4 beeps when unlocking (unless the alarm was activated whilst you was away). You can turn off the volumetric sensors by holding down the lock button on the card, you will hear 3 beeps when you do this.This feature is handy if you want to leave a window slightly open if you are leaving pets in car when you lock it up, or if something like a heavy storm or traffic is setting the alarm off. (It was this feature that was set too sensitive on my faulty alarm, you cannot alter the sensitivity only turn it off, hence new alarm unit fitted.)
You can also turn off the "tilt" feature, but according to the manual (

), to do this you must turn the ignition on and off 3 times, then lock the car within 50 seconds.Once again total nonsense from the manual.

All you need to do is lock the car and hold down the lock button until you hear the 3 beeps.Basically by holding down the lock button on the card you are not just deactivating the volumetric but also the tilt feature, yet still protecting the car with the immobiliser and voltage sensor (when internal light comes via opening any door or boot). Hope this might help a little into understanding the alarm.
