This was a test of the Thunderbolt 1003 siren test and a bonus at the end, sorry for the lag, it's my fps were decreasing
IMPORTANT!: I'm no longer able to remake this video any more and unable to give game link due to Roblox released a update which removed the siren sounds
Here is some more detailed info about the siren and the signal meanings
FS Thunderbolt 1003:
The Thunderbolt 1003 is a discontinued Dual-Tone Civil Defense Siren produced by Federal Signal in 1959-1990. Every Thunderbolt has a sound output of 125-130 dBc at 100 feet, Unlike the 1000 and 1000T, This model has a bowtie that is on the horn, which are the solenoids, that blocks the top hole, then the bottom hole every 0.5 seconds to make the fire signal, known as the Hi-Lo signal. If this was single-tone instead of dual-tone with those solenoids attached and the siren was activated in the hi-lo signal, it would sound like the 1000 model, but it would sound bad. Every Thunderbolt siren has 3 major parts, The blower, rotator, and the chopper, all of these parts work together, the first is the blower, it's a supercharged motor-driven blower in a big rectangle yellow box that sits on the ground or next to the pole in the air, that supplies a big volume of air which amplify the sound more louder, without this, it would sound too quiet and almost nobody would hear it, next, its rotator, for everyone outdoor to hear it, a siren need a rotator to spin around for everyone to hear, without this, the siren will sound where its horn is facing and half of everyone will almost or not hear it at all. And now the most important major part, the chopper or rotor, for a siren to sound, a chopper is needed, the air is sucked in front of the chopper and sucked out of the holes on the side of the rotor, this will chop air and create pulsating air and create a sound, the faster it spins, the higher the frequency.
The buzzing at 2:32 was the solenoids being active
