I have completed a replacment of my old Pyronix alarm system to a new feature packed Pyronix Euro 64 v10 with th Keypad Eur-064. I have managed to configure all 8 onboard zones (imputs), the bell & the keypad. The only issue I am facing is that I now wish to add a PIR using one of the 2 Keypad imputs (zones). I have wired in the a new Pyronix PIR but I can not find the next steps to add it to the system. Should the new PIR be configured as input09 or are there any other steps I need to perform 1st?
