I never thought in a million years that a company would do that as it would be proprietary tech and wouldn't give that kind of info out.
As the one guy put it, paraphrased; 'We would rather tell you how it works, have you keep it, and then have you keep buying Whelen than try to reverse engineer it yourself and break it. Then you decide our stuff is no good. Other companies already reverse engineered it on day 1 anyway, and if they could make it as the same they would, but they don't.'
For the time being Whelen is still keeping their new an old software open to their customers and they have no problem helping you understand how it works. They do their own engineering in house so they are pretty proud of their designs, but they also have no delusions that other companies aren't copying it. They know that their designs are either too much trouble to replicate, already being replicated, or under patent. I give suggestions to them via a few different local and direct channels and it gets back to their engineering. Whelen has so many versions of stuff because they consider their products to be engineered not just "made". If you have a negative impression of their design they want to know why and either help you understand why it is the way it is or fix it. This attitude is why I love Whelen stuff and have since I was a teenager tinkering. No other company I bothered back in the late 80s early 90s sent a kid the schematic to their lightbar and hand wrote on it why a specific section seems overly complicated. I'm not kidding that's where I go some of my 8000 bar info.
