Old chubb alarm

I've got a chubb alarm from the early 80s and it uses negative hold off but I want to connect it to a panel that uses positive hold off. How can I do this?

I suppose we are talking positive trigger. Invert the trigger with a few basic components or a transistorised relay maybe easier.

 

or positive tamper return?
