I successfully installed my SPC4320 with IR sensor and Elmdene ELM300 internal sounder. This configuration works properly today.

I wanted to connect the external Rapier sounder but I have two issues:
- Tamper detection: I wired the tamper on sounder as explained in the Rapier manual by choosing the 2.2K resistor on the board and connected it directly to the TR pin on the SPC4320 but the tamper remains faulty even if the sounder is closed and fixed (sensors on the Rapier work well as confirmed by beep from the sounder).
- EX+ and EX- signals: In SPC Pro->Panel setting->Controller input and output->Output (please see attached screenshot), I try to commute the ext. bell by pressing the '?' on 'Test outputs' but level of the output remain the same. It works well with the int. bell.

If you would like to give me a call I will see if I can help.

i dont think the spc needs an eol resistor for tamper it should be a 0v return only.
