The Siren Board

Hello, I’ve been wondering for a long time if anybody has photos or videos of Emporia’s old siren system, I know there is a photo of one of their 500ATs but I was wondering if anybody has photos of their Thunderbolts or Allertors.

Hold up...

You just posted a photo that meets the criteria set forth in this thread in another thread. There's also vintage photos in the Siren Archive. Do your own research before posting here.
