The Siren Board

Perhaps this unit had it's motor replaced or possibly a early revision.

Eithier way if this is an model AX, it is indeed a older one.

so the X represents explosion proof? makes sense. how did they do that without removing the brushes?
so an explosion proof model L would be an LX?

As far as other versions of the 'X' subseries, the only one that hits my head is the RX, which was basically an old-style Model L with a cover over the intake. I'm not sure if the motor was different, and I couldn't find any pictures that weren't dead-end links or unknown, but that's what I remember.

Must've been because of debris that would get inside the rotor, scraping against and possibly creating sparks.. Just a shot in the dark as I have no idea if the Model RX (rumor has it, the RX was a coded L not a explosion-proof one) was just a coded L or not.

well, even a clean brushed motor will spark slightly as the brushes are always being worn down. thats why vacuums have hepa filters. in addition to filtering out the fine dust, it has to filter out the carbon particles.
on a side note, 3 phase motors are all explosion proof.
(Brushless) (BLDC/BLAC)

Brushless motors do exist, but...

IIRC Noie owns an RX, so he should bring up if that's true, but Federal made the Model PL/PD that had an elongated intake to fit a flapper mechanism used on the Pulsator series. There was also the JC that was (supposedly) a Model A/J inside a large conical housing with an extra electric input for a damper; there was a short video of one on YouTube, but it must have been taken down
