What does 'spacing' refer to in the context of sprinkler installation?

In the context of sprinkler installation, 'spacing' specifically refers to the distance between individual sprinkler heads. Proper spacing is crucial because it ensures that the water is distributed evenly over the area being protected by the sprinkler system. If the heads are too far apart, some areas may not receive adequate coverage in the event of a fire, leading to ineffective suppression efforts. Conversely, if they are too close together, it may result in over-saturation, causing water waste and potential damage.

Understanding this concept is essential for designing effective sprinkler systems that meet fire protection standards and adequately safeguard property and life. Each type of sprinkler has its own spacing guidelines based on factors like water discharge rate, type of hazard being protected, and building characteristics, which a certified installer must consider during installation.
