Fire Drill in Male Dorm

Semi-Annual fire drill in a male dorm where I work campus police. This is a short video and not all that great. I had to stop the video because I was having issues with keys and, as you'll hear, the first horn I passed sounded rather sickly and I wanted to check it out. I don't know the model of the horn, maybe a cousin to the 4903-9219 but higher pitched. The panel is a 4004. Pull station is an old Simplex Chevron with a small hex screw lock - probably an original from circa 1970.
