Hi, So I have made a bunch of sirens and I am going to tell you about them. So there are 5 models currently in production. 2 of them already installed. So the first one is called BushBeer 100. Making 100 decibels. Very common. And BushBeer 75 for industrial purposes. There will be 3 other models. T...

Hmm, do you have a CDL? Are you over 21?? Do you have any training as a commercial electrician? Can you separate your siren hobby from your job? If you can't honestly answer YES to EVERY one of these questions, you have work to do. Once you CAN answer YES to ALL these questions, you might have a sh...

Yes, it is in the compulert board, I forgot that is separate from the “main brain”. And yes that is what I meant by the ‘hard start’. As I said before, the city use to growl/single whoop test them randomly. Are growl tests done remotely or at the location? There isn’t a growl function on the Alertr...

This thread is for sirens that have been made out of something else eg. A blender or a heat machine. Post here if you like idk. Sweet they removed my karma buttons so now I can start to lay down the law. If this is indeed your 2nd account I suggest just viewing forms until you learn some post disci...

Outside of Milwaukee, Mequon has an abandoned one, all others in the state have long been removed.

This thread is beyond ancient, but I thought I would dig it up since I heard on the radio today that this siren is being replaced very soon. There used to be tons of Thunderbolts around here and this is one of the last ones left. I have dug through the city's Website so others do not have to. I hav...

That siren was originally in service in Grantsburg, WI on their old firehouse. It was mounted on a tower with a Federal Electric Type B underneath it. They built a new firehouse in 2015ish and they replaced it with a 508-128. The Type B and Mobil Directo were listed on the Surplus Auction sometime a...

If you look on siren dudes picture of the control box for Sarnia’s Alertronics, zoom in on the tone generator, and flip it upside down… there is a tag that reads “REV J 4/15/87”, and however these particular ( 12) sirens were configured with a hard windup, and a long wind down. Not sure if that was...

Hey Tom.....what type of primer do you use with XO? Etching or standard primer from Rustoleum? With the XO Rust, it is direct to metal. What we do on sirens with existing powder coated paint is grind the rust spots off, then rough up the surface with an abrasive pad. Then clean with soap and water....

I have experienced the same problem with Rustoleum even the stuff in the can. I painted parts of my 500 SHST with the safety yellow and let them sit outside for a year. Within a year they were peeling and flaking. Cruz told me about XO Rust and I have been using it ever since. It seems like a high-q...
