Anyway, the firefighters appeared to be out on a run at that time so I wasn't able to ask any questions but I walked into the back lot and took a few pictures. The siren itself was located on the training tower, which probably was also used for live burns, and appeared to be in a very bad shape with rust and smoke all over. There was an opened door at the bottom of the training tower which lead to a stairwell and the siren controls were under some stairs but the power does not appear to be on.

South side of the blower box (OK, you can see my shadow)

Ignore what someone wrote above the CD symbol on this side.

Looking into the stairwell with the control cabinet in the back

The stairs did go up to the roof but I didn't bring a flashlight and there was fire damage on the upper level so I didn't want to climb them since I feared stepping on a weak spot and falling three stories. Otherwise, I would have had a picture inches from the horn.
One last shot from the back before I left
