A video of my low-pitched 2901-9838 horn. This particular alarm came bundled with my 4903-9102 light plate (not pictured in the video).
Not sure why I never bothered to do a standalone test of this horn until recently, given that I acquired this horn (along with the aforementioned -9102 light plate that came with it) way back in 2012.
Though, you could argue that I have already done so. However, I used different housings on different occasions, namely, with the cover that came with my 2901-9840, and the shell of my 4901-9805.
