The way those Thunderbolt 1003s work is pretty interesting. Those 2 little boxes up behind the horn are the solenoid boxes. The chopper inside the oval portion is what's called a "dual tone" chopper. It creates a high tone, and a low tone. Those solenoids push a little door over the opening that lets the sound into the horn. When the high tone is open, the low tone is closed. It alternates that to create the "Hi-Lo" tone. There is a separate control box that times the opening and closing of those doors. Definitely check that one out if you can find a test time for it.
The parrots here on long Island was apparently from an accident involving a truck carrying pets to a store in the vicinity of Lindenhurst, copaigue .Montauk hwy. And have spread out and have grown quickly .I've even seen them in the bay shore area.
That Model 2 looks like it actually has power. Unless that silver box I caught a glimpse of is something else. 🤔 As for the Thunderbolt 1003, you are correct! They have an additional control relay for the solenoids that can give them 4 additional signals. Aside from the usual Alert and Wail signal, they can do Hi-Lo, Alternate Wail, Steady Pulse, and Pulsed Wail.
As I may have mentioned in the videos, I grew up hearing the sirens, but gave no thought to them other than something that existed as part of my environment. Now, older, I'm curious about the sirens, as well as the history of the Island I grew up on.
this was uploaded one day after france's siren test, sadly the siren i wanted to film did not sound off because the city hall which controls the siren completely forgot to enable it, what a weird failure.

Nice video! Would love to see siren walks in different countries like Hungary (where I live) or Germany, because the ones out here are much different.
I would love to do such walks, just need to figure out how to get across the pond, but I'd also watch others do them as well.
Hungary gang
That Thunderbolt 1003 at 6:20 was recently repainted Red, it used to be a bright yellow. Nice find!
It did look newly painted.
Great walk with a great variety of sirens, nice ! I really like that bright red Thunderbolt 1003, it looks really good like that

At 6:20 the Thunderbolt 1003 sounds at noon everyday in Hi-lo signal but if it does maybe check it out one day.
I'll keep my ear out for it.
