The STH-10 was an omnidirectional, electromechanical siren produced by Federal Signal Corporation. Production began in 1954 and was ceased in the early to mid 90s. 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 in 2006, with the new and more efficient Eclipse-8 taking it's place. The STH-10 was created as an alternative siren from the STL-10, mainly for fire departments or non-civil defence uses, however, some places used it as one or both (as a Civil Defence Siren and Fire Siren).
