When there are obstacles near the sprinkler head, it shall comply with the provisions of section 7.2 of this specification or add a nozzle to compensate the spray intensity.
7.1.2 the arrangement of vertical and droop sprinklers, including the distance between nozzles on the same water distribution branch pipe and the distance between adjacent water distribution branches, shall be determined according to the spray intensity of the system, the flow coefficient of the nozzle and the working pressure, and shall not be greater than the provisions in table 7.1.2, and shall not be less than 2.4 M.
The nozzles should be set above the passageways in libraries, archives, shopping malls and warehouses. The horizontal distance between the sprinkler head and the protected object shall not be less than 0.3m; the minimum vertical distance between the sprinkler head and the protected object shall not be less than that specified in table 7.1.5.
