List of older, 'lower tone' electronic sirens

[bmd224]

I love how my older electronic sirens, such as my FS Director & FS Interceptor, have that lower frequency deep sound on the 'wail' siren tone.
Today's newer electronic sirens are all too high pitched, in my opinion.
What are some electronic siren models that have a lower siren tone, like the Director & Interceptor?
Hopefully this will lead to an inclusive list, or even a sticky, if enough knowledge is posted.

Blue face Southern VP sirens were my favorites growing up. Low tones on them too.

No, the Federal PA150, PA170, PA200, PA15A series 1E and PA20A series 2E all have screamy high-pitched wail and yelp tones like the electronic sirens we hear nowadays. They were manufactured in the 1970s and 1980s.

Federal's low-pitched electronic sirens were manufactured in the 1960s. They include the PA5, PA10, PA15, PA20, PA15A series 1B 1C and 1D, and PA20A series 2B 2C and 2D. There was also the Federal PA1 and PA2 made in the late 1950s.

Other low-pitched electronic sirens include the Fyr-Fyter Penetrator, General Electric Power-Call / Siren, Heathkit GD-18, Smith & Wesson Magnum series electronic sirens,
Carson SA300 and SA400 (the early Whelen WS 295 and Southern VP SA series sirens were based on these models), Signal Stat Stat VI and Stat VII, North American Signal Siren Master, Sireno Projector, and the Whelen WS-224.

I'm sure there's a lot more, but I can't think of any others off the top of my head.

I prefer the late 1960s versions of the Director and Interceptor. They sing.
