Not to my knowledge, Chris. Its a fairly rubbish alarm to be quite frank.
CharlieBoy - if you're seriously worried about the alloys then speak to a local audio/security firm, they can let you know whats what. I'm sure that a couple of sets of locking nuts will be sufficient to deter anyone but a professional thief, the ST alloys are nothing special anyway.
Its either that or move to a slightly less dubious area...
