The STH-10 was an omnidirectional, electromechanical siren produced by Federal Signal Corporation, originally from 1954 to 1993, and on special order between that year and 2000.

In 2000, the siren was rebooted, however, due to the attempt to use cheaper parts and some faults, the siren was discontinued in 2006, along with Federal Signal's many other sirens including the EOWS Series.

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).
