The FD in the next town south of my place (Melville) used to have *years* ago an STL-10 as one of their satellite whistles. This one had a slightly faster wind-up and achieved full-cycle for about 10 seconds before easing back down. It was junked when I was maybe 15 (I'm 36); so it must have been a venerable oldie.
Maybe this one was programmed to fast wail or something... :?:

Were the motors from the STH-10, interchangeable with the STL-10 and vice-a-versa?

I believe the motor interchanges within the STH/STL/SD-10/500 serieses.

I thought STH/STL standed for Single Toned High/Low, and the 10
standed for 10 H.P.

I believe that this recording is actually an ATI in San Francisco, which are programmed to sound a recording made from one of their old STL-10s. The real STL-10 sounds exactly like this from a distance. I was in San Francisco yesterday. It was sad to see all the STL-10's gone and replaced by ATI speakers, which apparently cannot be heard from many places. The Ferry Building, which once hosted the world-famous Heath Siren, now has eight ATI speakers. Two point north, two point south, four point west, and none point east (sorry, Oakland!).

ATI's are no good, why have something that wont do it's job? most people can't hear them due to the sound being "fake" and not pure like a chopped air stream!(which travels a lot beter than speakers) :D

I found the recording of a STH-10, and i like that more than the STL-10 posted bofore. The STL in that recording sounds like a frog like someone said!
