Fire Water Network normally have both Motor Driven and Diesel Engine Driven Pumps for emergency use in case Fire Water Network pressure drops below certain set point.
My question is, normally motor driven pumps are designed to kick-in on Auto start. Is it possible to design the operating philosophy so that Diesel Engine Driven pump kicks in first and then the Motor driven pumps? What are the pros & cons ? Is there any relevant NFPA code which is applicable?
