This should get you started,so panel to sounder as follows:
EXT BELL to +
SAB HOLD to -
EXT BELL - to BELL
PGM OP4 to STB
TAMP RTN to BT
SAB HOLD with 4k7 fitted to BELL -
At sounder link TAMP to 12v -
There's two TAMP terminals on the sounder the second one down is the TAMP RETURN!,
Remember the HKC's are EOL's so use the resistors provided with the panel.
That should get you started,also if you use the engineers hold off it's an OV trigger.
