In the future, I most likely will start a company that will manufacture sirens, and I need to know how to build a control cabinet like the Federal Signal SiraTone / MC Cabinet or the Whelen cabinets. So I'm saying I need to build cabinet that would have buttons that would play a specific tone, and have an AUX or some sound jack. The most thing I need to know how to build is the sound buttons (Signals / tones interface), What parts do I need to build that, and what do I need to use?
I would like to have the software information too, because I need to have the software to build one.
