In NFPA 13, pendents and upright heads must be kept a certain distance from walls, in addition to other requirements. NFPA 72 Figure A17.6.3.1.3.1 illustrates what 13 is saying in 8.6.3.3, and contains a note stating: measurements shown are to the closest edge of the detector. The maximum spacing between two sprinklers is determined by the rating on the sprinkler head (usually 15 feet, but there are other spacing distances, depending on the manufacturer). How do I calculate sprinkler spacing?
