I've been fitting Texecom bell boxes for years but after a spare of sounder failures ive started to fit the deltabell, if you want a good visual deterrent you cant go wrong with the backlit delta...

Deltabell.

It's one of the few bells that meets the new Grade 3 requirements (but you don't need that one!) so lots of professional installers are using it now.
