This is a video from a few days back. This is unit #17 in McKinney, TX. Surprisingly it went off at 12:00 noon on the dot! It was very loud and you could feel it in your chest. A man asked me what was going on, then asked me to translate the siren name into Chinese so he could post a post saying a Whelen WPS 4004 went off in McKinney. Does anyone know what controller this uses to only get to 380-400hz? I'm guessing a 2030 because siren #16 runs the tone the same as this but runs in 560hz alert. I believe that it was rotating faster than it did last time.
Take pride in what you love to do, no matter how much others will criticize you.
