The STH-10 was an omnidirectional, electromechanical siren produced by Federal Signal Corporation. Production began in 1954 and was ceased in December 1995. The STH-10 was then brought back into mainstream production around 1998.
Around 1998, the siren was rebooted, however, due to the attempt to use cheaper parts and some faults, the siren was discontinued on December 5th, 2005, with the new and more efficient Eclipse-8 taking its place in early 2006. The rebooted version of the STH-10 was three-phase only; the single-phase model was discontinued on December 4, 1995.
The STH-10 was created as an alternative siren from the STL-10, mainly for fire departments or non-civil defense uses, however, some places used it as one or both (as a Civil Defense Siren and Fire Siren).
