Here's a video of the siren.
The siren seems it has weird sounding windup and wind down. It sounds a Sterling M-10/M-5 winding up. It wasn't that loud when I heard it go off. It's loud as a Model 2. Does the siren have a blocked intake? Or it has a small chopper than other 9/12 port choppers?
Please read video description for more information about the siren.
Anyway, here are photos of the siren:

Here are photos of the CD&F radio/control box and the motor starter:



^It looks like someone has repainted the motor starter to red.
Note: The CD&F radio/control box and the motor starter photos were taken on December 7, 2013.
