Scantronic 9452 to Reson8 bellbox

[BrynRovers]

Decided to replace my old bellbox with a Reson8 one.
Unfortunately the markings are different.

Panel markings are
TR
+12
0V
Bell-
STR-

Bellbox
RTN-
HOLD OFF+
HOLD OFF-
TRIG
STR-

I "think" the connections between the two are the same sequence as above, but not sure by any means.
Any advice would really be appreciated.

Brilliant response time.
I have literally spent weeks looking for the solution but was even then not sure if I was correct.
It's a workshop alarm which has been going strong for a few years but the bellbox got a bit tatty.
Anyway, many thanks for your reply, it really is appreciated.
