Hi, thanks. I have 18 BD-20's connected to AIU's.
They have been working for about two months. Now one is showing occupancy all the time. The LED on the AIU is always on.
I have changed the bd20 but it still lights on the AIU.
There is only one wire going through the bd20.
When I disconnect the bd20 the led turns off.
I have cleaned the track but am at a loss as to what to try next.
