Sorry for the massive bump, but I have discovered two more sirens in the system. I have updated the map now and I also have some pictures of all four sirens. These other two sirens appear to be newly installed, because when I first discovered the third one, there was a small pile of dirt around the pole and there was also a derrick truck in the parking lot. Judging by what I heard from the test that I recently recorded and the size of the campus, these are the only four sirens on the campus. In case you want to hear these sirens, they test on the first Friday of the month in HI-LO at around 12, but when I recorded them they went off around 11:55.
The siren located at the Ford Buildings
The siren located behind the science building
