Sometimes the alarm doesn't sound until the window is smashed or the vehicle is towed away? It has some kind of delay on it!
I think it is noted in your hand book?

You might find that the alarm siren has been switched off. There is a keyswitch under the bonnet that you can turn on and off with the small cylindrical key that should have been provided with the main set.
