Besides the fact that the extinguishing nozzles are pointed away from the appliance instead of into it, there is no hood. I am not sure what this appliance is used for i.e., broiler or pizza oven, but I would have to assume that at least a type II hood would be required.

You are correct about the nozzle orientation! You can't really see it in this photo but it is under a type I hood. This is what the cooks call a salamander (broiler). THe nozzles were turned out for cleaning and never turned back, which raises the next question. Can the staff manipulate these systems for the purpose of cleaning? In SC, technically, no. Anyone changing the system must be licensed to do so. They were using the connection at an elbow as a swivel point to turn the nozzles out and away. Not good.
Next, you raise a good point about what type hood is required. If there is the possibility of grease laden vapors being produced, then a type I hood is required by most all codes and that invokes the suppression system too.
