It needs new amps. Sounds like more of a weak battery issue to me. That type of amplifier doesn't just suddenly reduce its wattage output to the drivers if the power source stays within the optimal voltage range. They will eventually drop out if the voltage dips down too low during operation, as is...

New sure if this has been mentioned before, but here is a fairly low 500AT in Bristol, TN. It really shows how big those beasts are. https://www.google.com/maps/@36.5544664,-82.2178939,3a,15y,312.38h,96.2t/data=!3m6!1e1!3m4!1sFcR5verT4ZkOrwN7daCVmw!2e0!7i13312!8i6656 Yes, that one was not only prev...

Really? Do you know the building? I'd love to try and find it on Google Maps This looks to be it. The siren was removed a while back. https://goo.gl/maps/dUUtDxp43AJ2 Correct, that was its former location. It was taken off of that building several years ago and relocated north to the industrial par...

Isn't the maximum 60Hz induction motor speed 3600RPM, since 60hz (revs per sec) x 60 seconds is 3600 RPM? Yes, that's the theorized speed of a two-pole induction motor, though rarely does one run at that speed even in an unloaded state due to slip between the motor's rotor and the revolving electro...

I feex! The hyperlink in the two quoted posts from stormsetter4 should redirect to the proper site now in case anyone clicks on those instead of the hyperlink in the OP.

Based on the size of the horns compared to the Vortex speaker housing and the fact that there are four of them, it could also very well be a Loudoun ES-5000 siren (aka the "Master Blaster"). I'm almost leaning more towards that being the case here instead of an E-Class or ATI, most especia...

If I recall, it was the 2V8 that got replaced, not the Model 2. No, it was originally a Model 2 that quit working. Ed Wise had a refurbished Sterling 2V8 that replaced the dead 2, but it may have just been a temporary thing until either he or the city found another Model 2. Either way, this one in ...

Here's the siren I live like right next to! It's a Whelen Vortex R4 Siren. Used to be a fin back, it blew off though. The fin didn't get blown off, it was taken off of it when the siren received a rotor retrofit kit to upgrade from the old belt drive to the modern gear drive. I'm not sure why only ...

I've always felt kind of bad for the folks living in those apartment buildings about 150 yards or so in direction that the horn faces. They've been getting the full brunt of that loud beast for about a decade now whenever it goes off. I guess one good thing about it is that they can't say they didn'...

There is a Bullard siren turned sideways at the Summit City fire station north of Redding, California. Most had twelve ports but the original versions were dual-headed horizontal sirens with six ports. There was a photo of a dual-head, dual-tone Bullard around somewhere, as well as photos of their ...
