The Siren Board

I was searching around Google Video for siren videos when I came across this one. It's of a Thunderbolt trying its best to sound "alert". But it obviously is having some problems. I don't know where this siren is but somebody ought to go out and fix it. I think its either got something stuck in it or maybe it isn't getting enough power. What do you guys think?

this was on the old board. and it some thing with that plate that conects the rotar to the base. i think

Wow, that siren needs repair badly. I think loudmouth is right, the siren's electrical connection is rusted or something... maybe corrosion?

I love how the people are talking in the background like its an amazing phenomenon (which its the first time they have ever seen a working siren! WOW!)

this was posted 3 times now

there is a problem with the collector rings, probably corroded

I like to hear peoples reactions when they hear a siren for the first time.

"Wow that thing is loud!" is peoples usual reactions.

Yeah, no crap, its an AIR RAID SIREN. Its SUPPOSED to be loud.

Of course, I have only seen working sirens in videos myself...

I've heard "Holy crap that was loud" to "OH $#!^ LETS GET THE HELL OUTTA HERE!!!!! NORTH KOREA IS &#$@ING NUKIN US!!!!!!!"

I don't think the rings are corroded, they look like brass. I think it's just a heavy build-up of dust or mould, or other dirt associated with damp air from the outside. And with that, the blower comes into play.
It doesn't need such a heavy repair. It's just fine like that for now.

Well, if they set the chopper voltage to the highest tap, and then run it for a couple of hours, maybe it will clean all the crud off the brushes, bearings, & rings!

Now, before you zap me, remember that we've had comments about reducing Tbolt sound output by stuffing a pillow in the horn, and cleaning out a Hurricane blower by plugging it in & ouring soapy water through it!

Yes, that Tbolt needs some TLC.

Indeed. No siren should struggle to wind up/down like that

I'm no avid siren expert, and I don't restore sirens as a living, hobby, or both o-o

But I think it's foolish to leave a civil defense siren to fall into disrepair

It really should be fixed T-T
