There's quite a few videos of newer Whelens and 3016s but only one that I know of of the omni WS 2000 series. So I shot a video of our newly installed WS 2008 durring today's test doing live voice and wail. Excuse the random and jittery beginning, I didn't think it was going to sound, especially as soon as I opened my car door. You'll hear the voice activation tones over my scanner just before the pre-voice alert tone starts up. I'll admit it was louder than I was expecting. This siren was formerly a Millstone nuclear power plant warning siren. We got a total of 6 for free, 2 are currently installed.
enjoy.
