Eurosec CP8 parallel

I have a Risco Eurosec CP8 with additional wireless sensors, keytags etc.

My 6 zone interface kit arrived and i got it set up ready to install.

I want to use Z6 as a state report (set/unset) and 1 as door contact. 2-3-4-5 are PIR motion sensors.
I’m interfacing to Home Assistant.

I have some challenges with the keyswitch which I have resolved in theory but ran out of time to test before my family went to bed!

Has anyone got similar working? Did you use PGM2 as the state sensor? Can i set it to ‘status’ to show set or unset? Something else?
