The alarm is telling you something.... it is in a code of sorts. Check page 37 of the owners manual....
If it goes off when you drive away, it isn't disarmed. (And starter kill wasn't obviously done)

PS: If it was professionally installed, take it back to the shop that put it in. If you put it in yourself, double check connections.

Unless he's remote starting (but not disarming) the car when this happens. In that case, it's behaving appropriately when he hits the brake, the R/S disengages, and it "sees" 12V on ignition when it shouldn't...
It sounds like your shock senser is getting triggered. This could be because
A) Things are hoooked up wrong
B) The shock sensor is too sensitive
C) The brain needs reset or is having a meltdown
D) Someone's messing w/ your car.
In cases A), B), and C), the correct answer is to have whoever put it in fix it. If that's you, check your connections and the sensitivity of the shock sensor...
Try disconnecting the harnesses from the brain and replugging them in.

Check your ignition connection also, your alarm shouldn't go off while you are driving
