That is an Amseco SSX-52S security siren. It is vandal-proof and is an indoor/outdoor siren.

Small bump to it but what are the motorized ones?

The first one is made by Federal Signal, but the name escapes me at the moment.
The second one looks like those small yellow sirens without a tag seen on eBay a lot, particularly with the grille design (although the stator grilles are not consistent with it).
The last one has me completely stumped; I would say it's from the 1920s or 30s.

Thanks! Tho you don’t know the names then that’s okay at least the first one is FS. That’s cool

Oooohhh my specialty! Allow me to help.

The first siren on the old WC54 Medic truck is a 24V Federal Electric of some kind, I am not sure what kind, since I'm better with 50s to modern fire sirens, but I've seen one of those before In a friend's siren shop, and it is heavy as HELL.

The second one on the Ford Fire Truck is an ADEMCO-looking model, which seems custom.
A ton of small Volunteer Fire Departments use custom sirens put together from old burglar or car alarms.
I own a USI Car alarm siren that was bought by a VFD in Ohio (not a meme or joke), given a custom motor and housing, and put on a truck in the 1950s. It's still sitting on the Diamond Plate it was on the truck.

After a little more digging, it looks more closely to be something similar to a Model 66L or WLR. Unfortunately, I'm still getting nuances of small sirens ironed out.
As for the second one, it looks like a Yugo siren with custom stator grilles.

The first siren is a Federal Model XL (or sometimes seen as the Super X). A heavier duty version of the Model WL seen quite often on military vehicles.
