This is a list of all the Alertronic series sirens. I'm not sure if it has been done before but here it is. I will add this to a spreadsheet in the future including wattage and common decibel rating.

AL-1000 - Looks just like a strike guard without the top case.
Db depends on the model
AL-2000 - I'm assuming it's almost the same as an AL-1000. I couldn't any images.
Db depending on the model
AL-4000 - A double-decker AL-2000. Nothing special
Db depending on the model
AL-6000 - Basically it's the same as an AL-6000R. I don't notice any visible changes.
