The STH-10 was an outdoor warning siren manufactured by the Federal Signal Corporation from 1955 until 2006.
History and description
The STH-10 was designed as an improved version of the STL-10 civil defense siren. It was an updated fire siren. During the late 1950s, a coded version called the STH-C was made. This could sound a pulsed/coded firecall for fire departments. The STH-10 came in single-phase 7.5 HP, and three-phase 10 HP. During its later years in production, a 7.5 HP three-phase version was made. The STH-10 was discontinued around 2005, and replaced with the Eclipse-8 outdoor warning siren. The STH-10 is still a very popular siren due to its efficient design.
