Excellent collection pieces! I have a Federal Signal-branded (not sure who originally made them however) “surface-mount” version of the left horn, called the 30A: it’s 24VAC, really old, & really loud! Odd how yours is tilted at an angle like that, since I’ve normally seen them mounted with the grille oriented vertically (can it be rotated to face such a direction?).
Are all of your horns the same voltage by any chance? (which would mean that you’d be able to run them all together as part of one setup)
If I had to take a guess when it comes to lining them up in “chronological order” (that is, when they were each introduced/released), I’d have to say first the 514, then…whatever the red one is numbered (as I was trying to determine such I found that there are versions of it that have a slightly different design: take a look (& a listen!)), & then finally the 411F, going by each of their designs.
im thinking the tilted star is just an error by either a technician or the factory itself, i can fix it by taking it apart but i am very lazy, lol. they are in order from oldest to newest (left to right) the 311 is either a really early 311F or a 311F(Surface) horn. the middle is a type 411F and the left a 514 as you stated, they are all 12vac, i have videos of each of them operating seperately! allthough i don’t think i can send them here…? i have alot of these national time horns.
Oh, yeah, maybe.
Ah okay, good.
Oh, really? Going by the design it seems like it would be the other way around (also if I had to guess “F” stands for “flush”, as in “flush-mount”).
Ah, cool. You can actually: just copy the link & then paste it in a message.
You do? A lot of the same model or many different models?
alot of different devices. i will send a few videos when i get the chance. the F does stand for flush, while S stands for surface.
