Take a look at Fig's 2-1-4 on that page for the various number of light configurations. There is a diagram with measurements on this page but it's pretty hard to read: http://www.tpub.com/celec/20.htm The system they describe has 12 boxes, 3 lights in each box arranged in rows of three boxes, two rows on each side of the runway. I'd put them closer to the runway and closer together than the papi system...I guess depending on the size of the runway (and length of approaches). Are you making these as 3D models?
