Re: Some siren questions
Why did some older Whelen Vortexes have weather vanes on the back?

Re: Some siren questions
It was supposedly there so that, in the case of a rotator malfunction, the siren head could be turned by the wind itself.

Re: Some siren questions
That's a pretty cool concept, lol. But in a bad storm aren't the winds just going to blow in one direction?4J25 wrote:It was supposedly there so that, in the case of a rotator malfunction, the siren head could be turned by the wind itself.

Re: Some siren questions
Actually, iirc the reason the fin-back was bad is that it caused tension on the motor, and it would cause the rotating mechanism's to break.
I own: One complete SiraTone, another SiraTone control module, a 1600W MC, 2 old ATI controllers, 2 round ATI horns with drivers, a ATI-DSA 4 thing, a Federal Signal FC, AR timer and Siratrol, and a small CD&F.

Re: Some siren questions
I always assumed the fin was there to place even wind loading on both sides of the siren so as to ease the twist acting on the rotator mechanism.
