@Macgregor It has both the siren mixed and the separate wail and yelp. i'm using the separate ones and dual toning them because its much better quality then the already mixed one. so as you can hear in one part of the video, i turn the wail off, something CFA do in real life for some reason (at intersections). This siren unfortunately is being faded out but we still have it on most newish tankers around the state including ours in Geelong. Link to the siren:
Also a link to my video where you can see it in real life, its the 2nd appliance (the tanker) that uses the LTS. The pumpers use a version of the brand Carson siren which is similar but is a little more lower pitched and the tones are slightly different:
