Today's siren of the day is the L1/F2 by ELEKTROR!

Good morning! Today's siren is not a L138 ripoff! Promise! The siren was firstly built in the 1940s by Elektror Karl W Müller. Serving its purpose as air raid siren during WW2. However what makes this siren different from the other air raid siren is that this is a rare dual tone siren. We know Europe is a bit of a stranger to these so it's always nice to find sirens like this. The siren is a combination of a L1 and a F2 rotor. The L1 rotor serves as the "Tweeter" (the high tone) and the F2 is the low tone counterpart.
