The Siren Board

Is there any video's out there showing the Whelen Visualert activating?

You can also see it in the How It's Made episode:

Thanks guys! I need to get out to Garland, TX Whelen Vortex's with the Visualert. I don't think anyone has filmed those yet.

Hold on.... Is that even a thing.. Vortex's with Visualert? It looks like its meant to fit right on the 2900 series sirens.. but a vortex? I wanna see that. If there is any, can you put a google street view link of one?

I don't live too far from Garland, I'll definitely have to make a trip this weekend.

I was going to try to get a video last week with the monthly tests but apparently they either don't test the siren at Firewheel or don't test it for very long. The verbiage on the their website is a little ambiguous about that particular unit. Long story short, I didn't plan ahead well enough and wasn't going to have enough time to find a unit I knew would work and find a good vantage to record from. I'll have to try again sometime next year.

This may be off topic, but I remember seeing a video a long time ago of a Sentry with a red beacon light on top. I think someone might know what I'm referring to

I found some info about garlands sirens on there website:
