3326-L iris motion sensor problem

I picked up 2 motion sensors and first 1 works fine 2nd one not so much. the second one shows battery and temp but no motion at all. it found it has a smart sense motion sensor and i changed it to smart sense motion/temp in the ide but that seem to have no affect and I also factory reset the sensor and rejoined it but it still doesn’t function.

any suggestions before I return it

I think the sensor (eye) is loose i picked it up and my thumb hit the sensor it flashed green and showed motion. im thinking i may have just gotten a bad one.

Yes, I had one do a similar thing. I exchanged it for a new one and it works much better.

I went and got a replacement the sensor and it works fine. I could tap the one i returned and it would show motion something must have been loose
