How to disable alarm siren

[Arkamo]

Hi

I came back yesterday from work. After about 20 minutes alarm went off.
That was my last evening and night.:mad:
Unlocking and locking the car with various time intervals triggering alarm.

I will go for a scan to my friend this weekend.
By this time is it possible to switch off the alarm horn as it makes me crazy and my neighbors too.
I have looked in the boot but could not find it.:1zhelp:

Thanks
Arek
