2011 I30

I own a 2011 I30 in the UK that did not come with an owner’s manual (bought privately) and the alarm goes off seemingly randomly a few times a day. I’ve replaced both the battery in the Key and battery in the car and nothing has seemed to help, I want to locate the alarm’s fuse in the fuse box to temporarily disable it until I can afford to take it to a garage to have it looked at, any advice?
