The Siren Board

^ Hahaha! ^

Interesting! Almost looks as though the top housing is designed to spin from the suction of the chopper.

Wasn't Keraj also an Indian manufacturer of warning devices? I think their page was listed on this site long ago.

Almost reminds me of one of those starters the use on jet engines! : P

I guess it could come in handy for an all-clear when no electrical power is available.

Isn't 16/8 already the ratio of the 10V2T?

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.

We had an older board that ceased ten years back.

I remember the company owner or a high-tier employee of theirs had an account on the old board.
