Yukon, Oklahoma Whelen Storm Chaser Video

First the siren is seen at 50 seconds. Goes off at 1.15 on whoop then goes into alert at 1.20min. Made them jump too!

Through out later in the video, more whelen's are heard sounding.

I've seen at least one other video of a newer Whelen doing this, a single whoop before starting up in full alert mode. My thinking was that either it was a brief malfunction, or that the activation signal had been sent a second time.

It's been doing that then for two or so years then: http://www.youtube.com/watch?v=czUU9Fd4xMk
