Alarm Hell

It's clearly alarm hell week this week.  The alarm in the house just keeps on beeping every 15-30mins for reasons unknown !  Pressing either the reset or clear buttons solves the issue, but then only temporarily.  Having scoured the internet for user manuals, it would seem the only way to silence the beast completely is with the operator code, but guess what - we don't have it ... and having contacted Oakwood I now know neither do they !  This could be a long night ...
