Green and Black wires are wrong way round in the sensor if you look very closely.

It will be one beep for zone 1 active.

Pretty sure that's not the case, tbh. The black and red are together on the left, the green and white are yet two central wires. The green is very dark.

Ok, things I've tried...

1) joined red and black at the sensor end. This allowed the alarm to set properly but, obviously, not trigger the alarm with movement.

2) joined blue and yellow at the sensor end. Immediately set off the tamper alarm. No change regarding being able to set the alarm.

3) swapped red and black st sensor. No change.

4) swapped white and green at sensor. Power to sensor stopped.

 

beginning to think I've damaged the sensor?

yes you can't just put anything anywhere you can damage it

Hi, Have you checked you have not blown the Aux fuse?

If you can use a multimeter you could (if competent to do so) test to see if you have 12vdc at the panel  aux terminal

Initially I didn't wire it in any other way other than the way the sensor had previously been wired. In debugging I may well have damaged it!

Perfectly competent to do so - I will try that, thanks.
