Struggling with alarm to smart conversion

Hi,

I currently have a eurosec alarm which I’m trying to connect up to 6 zone connected board, I have followed all instructions where I can but I have a constant red alarm LED on the board. The siren is strobe flashing but no sound (it triggers sound if I disconnect the fuse from the mains)

Have I got something wrong in the setup here?

The two green and white TMP wires are in zone 6 and I have 5 motion/sensor zones wired in (blue and yellow)

Bell and sound negative to the negative terminal on the connected board.

Looks like some pics are missing.
Do you have a wiring diagram or pic of the actual siren/strobe?
