I use a Xena XR1 BUT while it screams to make your ears bleed when disturbed it also does it at random without being disturbed. A problem when parked up e.g. outside a hotel at night? Oh Yes!
However, I've now taken its batteries out - that way it looks like it will deafen anyone who touches it - Result.

I have an Xena disk lock with an alarm.....it's never gone off without case, but when the battery went low it whined.....took an interesting half hour tracing the source in the garage! I didn't replace the battery...
