Wiring ADT elmdene to texecom premier 64w

Hi, I'm wiring my alarm after recently moving house. I took everything with me apart for the bell box. The new place has a fairly new looking ADT bell box already and I want to wire it up but struggling to get it it work. I've taken it down to wire correctly first.

I've wired it as follows:
H+ > 12V
H- > 0V
TR > Tamp
R- > Bell
ST- > Strobe

When I go to test the bell in engineer utils, it fires up the bell but switching back off doesn't stop the bell. Is there something else I need to change here?


Thanks

Apologies I've answered my own question! The above wiring works, the tamper switch wasn't fully closed, causing this issue. Now all resolved
