[Gil]

Well here it is.

a little bit into the video, it seems to have a power
struggle, which could be either a power surge, or a
dirty collector ring.

enjoy.

nice!

I think it is a power surge or an accidental turn-off, even though it would take more time than that to get it back up after a turn-off; a dirty collector-ring would have left it struggling in consistent intervals or all the way. That's my favorite part, though.

I love the video.

WOW: Very nice work!!!! I have never seen one of those on operation before.

I also think the Allertor is the neatest-looking siren. It's got class!

Good job Gil. Our test went sour on the T-Bolt in Stickney . I think the power problem was the contactor rings. I had the same episode in Lemont with the ACA P-50. It rotates once the debris on the slip ring is picked up by the contactor it momentarly loses contact which causes a arc to occur burning off the debis from the ring. That is why it doesn't do it in subsequent rotations the debris has been burned clear of the contact and ring. ACA has this issue appearently with their high powered rotational sirens. Maybe they should have used a wider ring with split contacts?

Awesome video gil!

LoL great video i think the Allertor just had a lil hicup lol and i donno if its just the video quality or the siren it self but it seemed to turn quicker then slow down affter it passed the camra.

No, if the Collector ring was a little dirty, when the brush went
passed it, it would most likely scrape off the dirt, then
it would not happen. You need to go back and look
at how a rotational siren works, because you seem
to have it wrong.

Cool video. I think that's the first one I've seen of one of those in action. As for the hiccup I'm guessing it was a small surge.

That dip could be a result of several things: (1); An internal problem with the RUN relay or solenoid in the control box which interrupted the motor supply power (such as dirty relay or solenoid breaker points, electronic problem in the relay triggering, radio/telephone, etc). (2); a momentary bad connection in the rotating contact surfaces or brushes up at the siren head. I have to say most likely it was local in the siren control circuitry rather than a main power dip from the city, I would guess.
