Have you talked directly with the pick system designing firms? In the case of the totes with slots I'd expect them to provide a technical report by competent persons that analyzes the fire protection methodology.
In the case of the original question, does the manufacturer provide an option A with sprinkler piping installed ready for connection providing X flow at Y pressure; or a design procedure to be used? These things have been out there at least thirty years. I'd hope the suppliers have become more sophisticated in that time. I've often had good luck often speaking directly with the lead engineer or rep engineer at the factory.
