What is the minimum distance between two sprinkler heads in a series?

The minimum distance between two sprinkler heads in a series is 6 feet, which is based on guidelines established in various fire protection standards. This requirement is in place to ensure that each sprinkler can adequately cover its designated area and effectively suppress fires without compromising the coverage of adjacent heads.

The 6-foot spacing rule helps prevent overlapping coverage that could cause water wastage and allows for the effective distribution of water across the intended protection area. Proper spacing is crucial in achieving an efficient fire suppression system and helps to minimize issues such as water damage from overspray.

In contrast, other distances indicated in the choices may exceed the necessary spacing required for effective operation of a sprinkler system. Larger distances would not adhere to the standard recommendations, potentially compromising the efficiency of fire suppression and making the system less effective in protecting the area. Understanding this spacing is critical for anyone involved in the design and installation of sprinkler systems.
