Low Mounted Thunderbolt 1000T in Hamilton Ohio Monthly Test

[mrboojay]

This was posted in the lowest mounted sirens thread, so I decided to get a video of it for the monthly test. This thing is pretty loud this close to the ground. I was able to get close to it (with protection) and the blower got pretty loud. I will have a cell phone video I took up close to the siren a little later.

Enjoy! http://youtu.be/3xTPVQ51fFM

At least whoever put it up so low had sense enough to set it to 8 rpm!

As high pitched as it was, as fast as it span, and as low as it was, it's an interesting unit all around. Thanks for grabbing this video!

Epic, epic win. Excellent video all around.

I knew those blowers were loud but geez.

I knew those blowers were loud but geez.

This one's blower is particularly loud due to it running in reverse, as in sucking air through the horn and blowing it out what's normally the blower's intake. Therefore, the vast majority of the blower's noise that typically is projected upwards with the air toward the chopper and harmonizes with the siren, is now coming out of the intake and downward toward the ground. That's always one of the tell-tale signs of one that has a blower running the incorrect way, the unusually loud volume from the blower as well as the "shallow", almost tinny sound that the siren itself has. Now don't get me wrong, those little screaming 4M blowers are still loud ones even when they're running the proper way; you can still usually hear them under the siren's tone.

You learn something new everyday. I appreciate the lesson, Ian!

I remember being told by Ian when they run in reverse, the chopper spins faster. If they make it up to that pitch it usually is the reverse blower. I think they also have a longer wind down too. The one in Batavia OH is the same way but different in female dog.

Wow! That thing is very loud sounding! It also has a very high rotator setting! GREAT video! :thup:

Great Video! :thup: Nice job on filming that low-mounted beast!

It is extremely low mounted. I was recently in Cincinnati for a day trip, and siren hunted as well. I came across that one, and I was able to touch the blower from underneath on the sidewalk.
