final version trust me

requires tone generator mod

AG1 to activate siren

so a while back i attempted to make a realistic RSH-10 in r*blox, and when i looked at the part index on the manual i realized just how complex thunderbeams actually are. sorry if the reflector disc looks a bit small, i tried with a larger one but it didn't fit between the frame.

changes:
- complete remodel
- new sound mechanic
- effective range now accurate (1.7 km/1 mi)

The Model RSH-10, advertised as the "Thunderbeam", was designed and created by Federal's then-chief designer, Earl Gosswiller in 1982. The siren was patented the same year, with the patent being published in 1985. The Thunderbeam would be Gosswiller's last patent, as he would retire from Federal in 1982. The siren was made in an attempt to amplify the sound of an omnidirectional siren without the need for an entire rotator assembly or horns.

The Model RSH-10 makes use of a very unique design. Rather than having the rotor and stator inside of a horn that rotates, the Model RSH-10 instead has a stationary rotor and stator with a separate rotating deflector. The Model RSH-10 makes use of Federal's Model STH-10 rotor and stator, but instead of using horns to project the sound, the sound is instead directed downwards, and this concentrated beam of sound is then deflected by a rotating disc deflector, which is driven at 2 rpm by a 1592:1 gear reduction drive on the bottom of the disc directly attached to the rotor using a long shaft. This greatly amplifies and projects the sound, allowing it to reach 124 dB at 100 ft, far more than the 115 dB of a standard Model STH-10. Federal Signal originally claimed the siren to reach 128 dB but later reduced it to 124 dB.

Because the disc is directly driven by the rotor, the disc rotates and coasts with the rotor like an ACA Penetrator siren. The gearbox underneath the disc requires regular maintenance and lubrication. An unmaintained gearbox has the risk of stripping the gears during operation, causing the disc to spin incredibly fast which may lead to further damage to the siren. The disc is enclosed inside a very large metal mesh cage, which protects it from the elements. The rotor and stator are housed inside of a cover which is shaped in a way to direct the sound downwards, while also preventing rain and debris from damaging the rotor and stator. The siren's bare 10 hp electric motor is located on top of this cover, and was available in 1 and 3 ph, the Model RSH-10B and Model RSH-10A respectively.
