Screech of brakes on unbridled criticism..... (joke)
OK Mark all sounds reasonable, you'll need an expander as James said, its a shame you didn't ask before you bought as although SW are a great place to buy
I would personally have bought from their extensive range of PIRs with EOL built in, such as Siemens, ditto for the contacts unless they are already EOL type, i.e.
Knight or Elmdene with built in 1k/1k resistors.
I'm not that familiar with the flex but be careful with the bells re: current draw; what I've done in the past is had one bell on SAB mode and the other on SCB, assuming
the AG6 supports this; if it does it will be very clear on the instructions.
Hope this helps!
