Federal Signal AS 320 DIG PO

This modification contains the siren FSV AS 320 DIG PO, which is used for example in Poland.

There are 2 versions of this mod:
1. You have 4 siren tones.
2. When you press “6” (with installed ELS), you can use a dual tone horn, but that replaces the yelp tone.

You can use the airhorn in both versions.
