The lowest you want to activate nitrous is 2500 RPM, primarily there is enough velocity to properly atomize the nitrous/fuel mixture. I have a NX wet kit and I've activated the nitrous at idle and the car just stalled due to the extreme richness of the fuel. As far as the redline issue, as long as you can monitor your RPM before you redline, either upshift or let off. All kits require you to be wide open throttle before nitrous is activated, but do make sure you are above 2500. To answer your question, the low end limitation is to prevent early activation, which can cause a backfire or a stall. The window is also to prevent accidental overreving such mis-shifts. Basically, if you know your RPM limit and know when to spray, you don't need the window. A shift light will be more usefull. Most drivers launch at 3000 rpm, so if you decide to spray on your launch you will have bad 60' times due to excessive wheel spin. With street tires and nitrous my 60' average 2.31 which is not great. Consider drag slicks if you want to take a second off the time.

But this window switch implies that u must have two extremes...soo.....WHAT IS THE LOWEST RPM YOU WANT TO SPRAY AT? myyyy only explenation for these references to not wanting to spray at low rpms is this...when racing(which is most likely when ur using n2o) the only time ur engine is ever in low rpm is maybe right at the beginning, which for anyone wanting to get good 60' times wont be in low rpms either...so is this low end limitation just to prevent wheel spin at low rpms off the line? or is there something unstable about an engine injected with n2o at low rpm?
