Here is an Omega 9000, apparently optioned for warning light control only:

UniTrol control switch box, similar to Federal Signal - auto parts - by owner - vehicle automotive sale - craigslist

UniTrol 9000 control box. Fair condition. Functions unknown. Indicators lights not working. Progressive 1,2,3 slide switch. 3 split rocker switches. One toggle switch. 6 1/2 wide, 3 1/4 deep, 2 3/4...

I believe that toggle switch is for the siren, but you need the siren amplifier and cable for the siren tones.

Tow/service truck light controller. The toggle switch is probably to go between regular horn and air horn.
