FDC or fire pump? Probably has an FDC but may be hidden behind a bush or back in the loading dock or by the main boiler room area. The FDC could also be by itself out front of the building, you’ll just see a pipe sticking out of the ground with the siamese connection on top. These are sometimes hard to see, heck, I’ve even missed them because they tend to blend into the flowerbed with all the bushes and trees that got planted around them! If you don’t have a fire pump, not necessarily a bad thing, just didn’t need it.
