Scantronic 9651 And Bell

Hi, I wounder if anyone could please advise me on this?

I have a Scantronic 9651 Control Panel and I'm a little unsure as how to connect the external bell.

The Control Panel as the following connections:

OP1 OP2 TR 12vAUX 0v

I understand that OP1 and OP2 apply a negative, TR is for tamper and 12v/0v supply the power.

The bell box has the following connections:

STB+ STB- HOLDOFF+ HOLDOFF- RTN TRG

This is now I think they should wire together:

OP1 to TRG

OP2 to STB-

TR to RTN

12V to HOLDOFF+

0V to HOLDOFF-

I wanted to check this was correct before I connected for real in case I damage something.

Can you please advise?

Much appreicated!

100% correct !!
