The Siren Board

Sounded like the Blitz, eh? Did any Spitfires and Messerschmitts have a dogfight outside while Heinkels were shot down by some other Spitfires?

Nice siren!

It looks as if these are designed based off of the broadmoor sirens (Klaxon CS-8). It would make sense since both of them are distributed by companies based in the UK

UPDATE: I fabricated a brush inspection cover out of brass for the one that was missing, replaced most of the screws with new stainless ones and made a temporary cover for the one solenoid out of sheet metal. I also installed new weather gaskets and will be getting a new solenoid cover cast for the one side, using the other one as a template and rigged the solenoids so they are always fully-open so I can get a full wind-down I will be doing a 220v test this weekend, stay tuned!

That test wouldn't happen to be using the solenoids(hi-lo) would it ?

No, they are still wired from the factory to open when power is applied and close when it is turned off. They are currently set to always stay open but I would like to do a high low test sometime in the future

The dampers are probably set to do that so that small animals and debris cant get into the intake ports.

If I'm correct, a Federal Signal 3T22 has its dampers closed when it is not in use and then when the motor recieves a current, the dampers automatically open depending on the cycle it is set to do (I'm just assuming because I always hear the metal clanking sound when they go off).

That'd be cool to somehow wire the siren so that you could have individual control of both of the dampers or find a way to code the dampers like an AF timer would.

3T22's always have their dampers open. They are protected by wire mesh screening. The clanking sound that you hear on startup of the high low signal is the first damper engaging for the cycle.

Once you do figure out the solenoids please make a video of Hi-Low

I have an AF timer but would need the proper RCMs (From a 3t22 or 1003) to operate them properly.
