The 2T22 is an omnidirectional siren that was produced by Federal Signal Corporation from 1955 to 1992. They have two rotors producing two different tones at the same time, powered by a 10hp dual shaft motor. Both rotors measure 15 inches in diameter, and are identical to the rotors used on the Model 5 and 2001 sirens.

It is a single phase 2hp siren and is single tone. Federal also made dual tone Model 2T. The Model 2 single tone siren has 5 ports and the dual tone Model 2T has 4/5 ports. Federal states in their old Model 2T manual that the Model 2T had an output of 100db at 100ft. Here's a close-up photo of a STH-10 at the Richardson fire training facility.

2016年1月5日 · Here is my video of a 2T22A near HNL airport. I was originally gonna video the 1000A located a few yards away from this siren. But I found out that the disconnect switch was in the off position. So last minute I came to this siren and filmed it. Hope you enjoy! Location: Wonderful Western Oregon. Good to hear the 2T22.
