I would like to have a siren controller/switch box hooked up to a volume controlled speaker so my friend could do on-hand siren demonstrations to his customers in his lights/sirens store without blowing their ears off or disturbing anyone too much..would it be possible to hook the sirens up to like a stereo speaker or a computer speaker or something so they can go from being as quiet as a whisper to as loud as the speaker will take, preferably without having to change the electrical current of the siren or speaker?
It would need the siren and alternative speaker to be hooked up together and then have both of them hooked into a power supply which would be plugged onto an electrical socket on the wall...anyway the idea is to have full siren tones, airhorn, manual, PA, etc function the same as off a standard siren installation in a car, just loads quieter and in a 'bench test' type situation instead of a full install. It would also be pretty cool to have that setup as a bit of fun with a lightbar in my recreation room in my house

It would probably be just 2 or 3 simple sirens on seperate speakers like C3 Microcom 2 or FS PA300 or FS MS4000 and maybe one more complicated model like a FS SS2000SM. Would also need to know the same thing as the siren setup, but would it work with a Federal Signal or Code 3 rocker switch setup at the same time to control any lights for demo/rec. room fun?
If anyone knows how that could work, or another way to get the same effect, plz let me know on this thread or via a PM, with maybe some good yet simple instructions or diagrams....or is what I am trying to do completely impossible???
Thanks,
Nic.
