If it's a long straight stair well then one of this 'Curtain' PIRs might be an idea.

Risco Group - Curtain PIR

Photo is a Risco branded PIR.

Unfortunately this model has a maximum of 3m height. I don't know, but hopefully there is some versions with a higher mounting height.

Focused detection area in 'x' axis is the key idea. It does mean multiple would be needed for a stair well with a corner.

I still agree to the other statements on why you really need one in a stair well, but here's something.

cyril7: ... the sensor will only trigger once the burglar gets to the top of the stairs, 5sec later than purhaps you wanted, is that really such a big deal? ...

In an emergency, every second counts. 5 seconds later could be 4 seconds too late.

That's a pure-IR which has the problem mentioned in a previous post, it'll detect the chandelier. The nice thing about the dual-tech wall sensor is that it won't false-trigger on that.

I'll call AAP when they're open again and see what they say about rotating the existing sensor 90 degrees, which would seem to solve the problem with the minimum amount of effort, and report back. In particular since the motion that's being checked for is vertical rather than horizontal, this would seem to be the best way to apply it.
