[FICTIONAL] Federal Signal STM-10B

A Single Tone Medium 10
Company is made by Federal Signal Co.

The STM-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 STM-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 STM-10 was created as an alternative siren from the STL-10 and STH-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). The STM-10 uses a 10 port chopper and stator. Making the same sound and pitch as the Xt22 with blocked up intake siren or ACA Hurricane and Super Sirex. The STM-10 sirens were going to have a coded damper at one point, but the idea was scrapped after a prototype was made.
