Ive just tested the anti drill terminals on an old ADT and you have to bridge it in order to activate the siren, so would a pressure mat do?

I remember a old skool metal double skin bell box with drill tamper and a pendulum fitted inside in case  anyone gave it a whack!

you can get in trouble for doing things like that

 

Why would you want to. A bell is a type of signalling just use more than 1 and better signalling. The bell usnt what deters intruders its the fear of getting caught. If Noone hears the bell Noone will respond etc etc

Looks like a nice sounder, got a bell box?

I am struggling to work out what box it was, was it one like this ressurected classic, but the deeper version...?

Binned it.
