Sorry about not having a place to upload this right now. Don't want to bother with webspace at this point. And I'm not so sure exactly how "well" this siren works. I have an audio recording of it that shows the blower(I believe) straining pretty hard. They also have the pitch set really high, which I'd love to convince them to change, heh.
I remember calling the dispatcher asking her to extend the test duration, and even though she sounded pretty unsure on the phone it looks like they did. They usually only test each signal for about 15 seconds, not nearly 60. I figured she did cause she usually does the fire call last but did it first for me cause I specifically asked her if she tested that function LOL.
