hello!

Can I install different versions of sirens on an ambulance, fire truck and police?

How to do it?

1. Search for a siren mod that you like in the downloads section. 

2. Download and install OpenIV (http://openiv.com/WebIV/guest.php?get=1). 

3. Read the README that comes with the mod you installed.

 

If this does not help, post again. :) 

 

EDIT: I may be stupid or something. If it's what the below people are asking, no, it's not possible.

No, you can't generally do this. The main wail and (IIRC) yelp tones are the same on all three vehicles. I think the priority tone can be different, though I'm not sure how to mix and match.

Unfortunately you cannot have a different siren for different emergency vehicles however the Ambulance and Firetruck do have their own tones.
