I know this is a bit over your buget but it is a good system for the £££s
See here

Or there is this system which is cheaper, and would probably fine for your requirements See Here

The outside sounder has a battery as well for back up plus if someone got at the alarm cable and cut it between the panel and the sounder the sounder battery kicks in and off goes the siren.

Any burglar who hasn't heard of a tamper loop or self contained bellbox isn't any sort of professional in his field is he, lets face it.

I remember an episode of a cartoon once, where they were trying to get a bellbox to stop sounding, was driving the whole town potty, in the end they smashed it up with a club hammer
