First one I'm fairly positive it's a PTR or an early Cicca, unfortunately there's very few if any information about these. Cicca sirens are a bit difficult to identify, as Cicca seem to have made two style of sirens, older 1940's-1950's models with the 3T22-like "cone" and the motor at the...
I concur, specifically it's for the stator's de-icing heater element, if you look a bit closer you can see a outer ring that connects to the junction box, that's the heater in question.
While these are quite mild compared to some of the insanity that has been posted in this thread, there's quite a few interesting installs in the Twin Cities area. Here's a few that come to mind. 1. A Thunderbolt mounted on a cell tower. The blower pipe is run through the inside of the tower. It's b...
Here's one from the depths of the board, the Model 3 in Komotini, Greece: https://www.airraidsirens.net/forums/viewtopic.php?t=15594&hilit=Model+3+Greece I recall also seeing a StreetView screenshot of a modulator near a Nuclear Power Plant in Europe, I can't recall the country where it was take...
There is (or maybe was) a Cyclone somewhere in or near Clydach, Swansea, which is actually quite well known.. Though apparently there's a rumor that it was replaced, but either way regardless if it's gone or not... I got another example though it may be stretching the definition a bit... Police cars...
I'm not that surprised to be honest, I recall that there's a McDonald's in my area that has a beige* System Sensor SpectrAlert classic above the door that leads to the Co2 tank storage room (for the carbonated drink fountains), I'm pretty sure it's for some kind of Co2 leakage alarm of some kind, bu...
2nd siren is a Federal Electric Model 2, possibly a FEDELCODE (FEDeral ELectric CODEd) though many FEDELCODES seem to have their coding system missing. The 1st siren, I am not very sure if it's a Carter... I'd say it most likely is either a Federal Model/Type B or a Sterling M-5/M-10, it's hard to s...
As far as I know sirens in France (back in the ol' days) seldom had timers, it was just a plain power relay tied to a push-button that you'd manually had to press (right now I kinda regret having passed up one of these on Leboncoin given how extremely rare these are...) to activate the siren manuall...
Sorry for bumping such an old thread. The CTI Omnidirectional model cannot be a french siren, due to what I believe, that most French sirens were at a low tone, compared to the CTI model’s 10 Port fitting. Also, most French sirens had round horns, not square. Even if there was a French siren like t...
