Cisco Controller 2504 Firmware  version - 7.6.130.0

Update the firmware of the controller.  1852 requires the controller to be running, a minimum of, 8.1.111.0 (and later).  

I strongly recommend loading 8.2.141.0 if there are no legacy APs around.  

And don't forget to read the Release Notes.

Access Point support no matter if they are indoor or outdoor is code dependent. You need to choose any of the outdoor AP's and then look at the matrix to determine what controller code you need on your 2504.
