Most electronic 4903-series horn/strobes sorta sound like the TrueAlert, but only some models sound identical to the latter.

btw, that was a joke.

yeah but lowered pitch

Thanks for clarifying!

Now I know its not a 9237, but I’m quite sure it’s not a 9219. I know for sure it’s a lower-pitched electronic 4903 from the mid-90s, but the exact number, I have no Idea.

It might of been lowered pitched before, but maybe since it being on Continuous for a while, might of affected the horn making it a bit higher pitched. If you go to my channel, https://www.youtube.com/@theoffical4903 and click on my fire drill video, you will hear a 9237, a low pitched 4903, FROM the 90’s and early 2000’s.
