I looked at all my old Altec Giant Voice literature and can't find any information on warning tone frequency. One would have to watch the video clip on youtube and try to simulate that sound. I wish I knew what that frequency was.

Those horns were made by Altec and are old, but they are not the original multi cell horns. My Father started working out there in1967. I was born in 1971. From 1978 through 1985, I would go to work with my Father a few days during the summer. He would drive me around, so I could look at the Altec s...

That's good to know. It would be great, if Redstone would allow you to take a picture of the original horn(s). If the controller has electrical power, then I would say the system is still being used.

Being mature and professional works wonders and pleases everyone! ;) What exactly was in the system, was it all Thunderbolts, or were there other sirens? Hey Thunderbolt 10031! I've posted the list below. The siren removed at the "Golden Spur Mobile Home Park" was a Federal Model 2 or 2T....

Yes , there was a discussion, I was the OP viewtopic.php?f=2&t=20625 look towards the bottom of page 1..... The quickest way to be told NO is to start bothering Saline County or the city of Salina about their soon to be replaced sirens. IF the sirens that are being replaced are to be disposed o...
