Tim, also realize that it is going to have to be approved by the local authorities. They may have an issue with a hybrid system that the EoR specifies. Best to make sure he is on board with that as well. (There is an FM in CT that will not accept FM Global design criteria. Consequently, the systems ends up needing 2 sets of plans, one the meets NFPA and one for FM Global. Of course the same design with different hydraulics). The EoR may spec marshmallows, but if the AHJ wants chocolate and graham crackers as well, you will need to provide everything.
