Disruptive Alarm on a Zafira

I have a 53-Plate Vauxhall and every night the alarm goes off at 3am. Why is that? I have disconnected the battery, but it's too much hassle if you need to go out early in the morning.

There is a known fault with the alarm system. You might minimise it by switching the ventilation to recirculate, closing all cabin vents, directing heater to the footwell and turning to maximum heat. That will minimise changes to air pressure inside the car.
