2013年8月27日 · Ralph Ratcliffe Models has released a 1/87 scale 3T22 and a revamped 1/87 scale STH-10. Both models now feature rounded out ends of the horns to give them a somewhat hollow look. The horns of the old STH-10 were solid and you'd have to take a Dremel tool to hollow them out. An SD-10 is planned somewhere down the line, according to Ralph.

The 3T22 was an Omnidirectional Warning Siren by Federal Signal made around the 1960s that contains two Rows of Horns and is the Solenoid Version of the 2T22 and is Able to HI-LO... The 3T22A and 3T22B versions also exist.

2020年2月4日 · I don't own any sirens myself, but I'd say the 3T22 is one of the cooler sirens out there, being one of the few with coding dampers and capable of hi-lo signals. The 10/12 port ratio also sounds really nice. They're quite large assembled, but with the horns removed they're a lot more manageable, if tall.

2025年3月21日 · The Model 2T22 and Model 3T22 (2 or 3 Tone, 22 horns/ports) are a pair of dual rotor omnidirectional sirens that were produced by Federal Signal over a span of nearly 40 years. These are some of the most well-known and iconic sirens with a distinctive sound and are still commonly found today.
