Scantronic 9448+ pir no power

[ASB1]

Hi having changed a pir on a scantronic 9448+. I have no power to any of the other pirs. I have changed the fuse and still no power. Any advice would be much appreciated.

Did you change the correct fuse ?

Measured AUX output voltage?

Changed the wrong fuse?

Hi yes changed right one. But changed the other two as well.

No reading on aux output. There is bell output though. So Tried pir on bell output and that works; however, fault still showing. If that makes any sense?

What rated fuse did you put in, 1A? Is it still intact or has that blown without you realising.
New pir wired up correctly?

Yes 1amp. Yea check pir is correctly wired. The fuse is still intact.

Remove all pir aux wiring from pcb terminals and then take voltage reading without any devices connected.
