A little searching round has thrown up this:

Go to the ebay auction and watch the video (small box at the top of the listing) Seems the warning beeps before alarm are good. Also I think it'll fit round some more bike parts than the disc specific ones mentioned before. Might have a punt.

When it is in alarm mode, if there is any slight wind movement the alarm will not sound, the control unit can recognize tampering and innocent movement i.e. wind conditions, if tampered with, the lock will sound 3 ear piercing bleeps and automatically increase sensitivity, if tampered again within 1-30 seconds just even a slight movement or any foreign metal contact on the shackle will immediately sound a 10 second 110db alarm.. After the 10 second alarm has sounded the lock will be in a high alert state (maximum sensitivity) for 30 seconds and will repeat the 10 second alarm if tampered again and thereafter will drop sensitivity one level at a time after it has sensed no movement for 30 seconds. This unique technology ensures no false alarms,
