How Do I reset the alarm without any codes?

Hi,

Me and my partner do not have any of the codes as the alarm came with the house and we cannot contact the person we bought from. The other day something sent all alarms on the street off and since then it beeps everytime we open the door. I tried taking out the fuse and battery but this just sends the alarm off, even when I took out the wires going to the speakers?

We have no Idea what to do and it does not have a make on the box to ring the company. The only word on there is CONSUL? Googled this and nothing comes that is relevant.

Please Help!
