In situations where multiple air terminals are required, the perimeter air terminals shall be positioned so that they are no more than from the outside edge of the building nor shall be ESE Air 230’ (70m) Terminals be spaced more than apart at any time. A cross run cable shall be provided at 460’ (140m) intervals of building (610m) in length in any direction. See Figure 1000’ (305m) When exceed 200’ 10.8.1. The recommended number and placement of air terminals is based solely on Heary 30 Bros.’ years of experience and its air terminals and the configuration of those terminals have not been scientifically proven or guaranteed to have a measurable zone of protection. Down Conductors in situations where multiple ESE Air Terminals are required shall be spaced at intervals no more than apart around the perimeter of the structure. 500’ (152m) Bonding connections shall be made with main size conductor to all rebar, reinforcing rod, structural steel, interior wall wire mesh, nylon mesh in stucco walls, etc., whether exposed or not, at the upper and lower extremities of each down conductor. Care shall be taken to assure that all rebar, reinforcing rod, structural steel, interior wall mesh, nylon mesh in stucco walls etc, whether exposed or not is electrically continuous or made so. (See Fig. 10.9.1 and Fig 10.9.2).
