I was just thinking about this as I was messing around with my sirens and all of my fire and ems units.... Would it now be a lot easier to make a Q siren  because ELS 7 has the separate horn and manual modes built into it? I am going to mess around with some sirens this weekend but I am just curious if anyone else has thought of this or is working on it?

Nah. It's not a true mechanical, manual siren (like the Q). Basically it just plays a soundfile.

The title of the thread says E-Q2B, not Q2B. The E-Q2B is a Federal Signal siren designed to replicate the sound of a Q with an electronic siren (which draws much less power) (http://www.fedsig.com/products/310/e_q2b).

I've had this thought too. But just like Break said, it wouldn't wind down like a normal Q or E-Q. Although what I have done is created an air horn to replace the electronic horn so when I press Y I have a true air horn I can clear intersections with (: it's pretty cool.

It wouldn't be hard to get a Q-siren sound. The hard part is getting it to loop and still sound normal.. I've done it before for my own personal use but lost the file. So good luck if you're going to try!

Maybe in the future someone will create a mod that can play more and longer sound files, so we can have a proper manual siren - technically it's possible.

It's definitely possible. I'd make things a whole lot easier.

I was thinking about an electronic Q and an old manual Q, same principals with wind up and wind down, just different sounds. WBRPDProduction I would like to hear the air horns you have created if you are willing to share them?

yoyu can do it with the same sound of the real manual thing like if you did it with different patterns instead of up and down up and down, it would be awesome if it sounded like the manuals.
