Alfa alarm

No idea why, but my 2007 939 Spider will sporadically have its alarm go off in the middle of the night - all very embarrassing?

Being a convertible, I suppose the roof might be more susceptible to say a curious cat setting it off, but aside from leaving it unalarmed, I wonder how it is possible to trace a sporadic fault?

I would welcome any ideas?

May be of help

Excellent Barybob - many thanks.
I was unaware it might have been a common issue on 2006 Breras and 2007 Spiders.
Must try the deadlock option before I can get it to a specialist.
Thanks again.
