Dude! I just snagged a model Q2A from an old fire truck for $100
I mounted it to my jeep. This siren replaces my Model 78. I'll sell it off. Video's to follow!

I'm jealous.
Sell me your model 78.
I'll try to do tests in water at low speed.
Would rather attach a hand crank to it for that.
I should. Is it 6v or 12v?q2bman wrote:Oh no sir. My siren would have to go to a good home! No watery grave!

I'm in Fort Worth. Do you have something to power this 78? Takes a ton of juice.
Gotta try it and see for myself.JasonC wrote:Why do you want to put a siren in water so bad? Its already a documented scientific fact of what happens when you do that (when you have enough power). A 78 wouldn't have enough power to do anything more than spin in the water and maybe make a few cavitation bubbles. Look at a pump for another example. Pumps have impellers almost identical to siren rotors.
It is - unless done slowly and carefully.q2bman wrote:just seems like siren and water = bad combination.
Didn't realize it is same amperage draw.q2bman wrote:The 78 is a 12v siren. Pulls the same current as a Q. 100 Amp initial pull.
It can be operated with low power but it takes forever to wind up.
