Can someone help with my old veritas alarm?

I really need help. Moved into a repossession about a week ago. Managed to find the alarm code and reset it to my own code etc. But no matter if i factory reset the alarm or what I do, the ‘chime’ for when someone walks through the door keeps going off randomly, even if i’m not in the flat, it’s every 30 seconds at this point and i don’t know what to do.
