Another sick EOWS612

This one was recently posted to Youtube. It's not as loud as it should be, and it sounds terrible. That popping you hear is not from the recorder, but it's from the siren. Listen as the siren just fades out completely, then abruptly comes back on for the winddown. The person who made the video thinks the siren may have a bad driver.

You can also hear a Whelen in the video.

It would seem more likely that something was wrong with the batteries. That would explain the siren's inability to produce sound (with any sort of sound pressure or output consistency) and the super-slow rotation.

But, that's just a theory.

I wonder why it came back on during the winddown. If it was the batteries, it probably wouldn't have done that. It could have been a short in the speakers, or something like that. This siren is very sick though. There was another sick EOWS612 posted here not too long ago, but it wasn't the same siren.

I would think to check the slip rings.

It's an electronic siren.

There are slip rings in the siren for rotation of the head, and the drivers. Since an EOWS model rotates, it needs slip-rings to provide power to everything in the head.

Oh, sorry about that. It may very well be the slip rings then. Do the EOWS models rotate in a full circle, or do they oscelate like some of the Whelens?

Fully rotate, as per the slip-rings. :)
