An ADA door opens when walking past it

Should an ADA door open to the outside whenever someone passes it? No! Our customer was dealing with issues like this since the building was opened two years ago. I fixed this problem in about 15 seconds once i got to the head end.
It really is a disgrace that we have people out there in this industry that would leave a customer so vulnerable and for so long for such a simple fix. The rex button and the motion sensor wires were crossed. Simple!
