The RSH-10, also known as the Thunderbeam, was a rotating electromechanical siren produced by Federal Signal Corporation. RSH stands for Rotating Single-Tone High. Its unusual design consists of a hornless STH-10 mounted at the top with a slanted disc in a cage below. The housing directs sound downward from the rotor and stator, onto the disc. The disc is rotated using a gear reduction off of the rotor shaft, directing the sound in different directions.
