my alarm used to go off when it was armed for no reason, it turned out to be a broken sensor or somthing to do with the sensors, so a little gust of wind would just set it off. it might be somthing like that but if not then look in your alarm manual if you have one) and see if it says anything about it going off when the battreys low etc.

my alarm used to do this but only in cold temperatures durring the winter and really hot temps in the summer

mine does it when its raining hard! i think it must get a sensor wet! " it only ever happens as a fit bird walks past! making me look like a right plonker!
