Simplex 2901-9846 Test

In Code 3, here it is; a high-quality recording of a 2901-9846 on a 4903-9105, in filtered DC of course!

I always thought that these horns were several times more louder than the 9838s but they seem to be the same volume. Great job on the test!

They’re actually about 10-20 db louder. My basement is large so the sound is displaced over a wide area. The 9846 is 100-110db @10ft and the 9838 is about 85-90ish db at 10 ft.
