What is the maximum distance horizontally that heads can be out of center in attics?

• A. 1 inch to 8 inches
• B. 1 inch to 10 inches
• C. 1 inch to 12 inches
• D. 1 inch to 15 inches

Answer: (C)

The maximum horizontal distance that sprinkler heads can be out of center in attics is specified to be 12 inches. This standard is based on safety and operational effectiveness, ensuring that water distribution is adequate in the event of a fire. When sprinkler heads are positioned too far from their intended center, there is a risk that the spray pattern may be compromised, diminishing the effectiveness of the fire suppression system. A distance of 12 inches strikes a balance between installation flexibility and the necessary coverage area for an effective sprinkler system in attics, which can often have obstructions and irregular shapes. This requirement emphasizes the importance of adhering to installation guidelines to ensure that every area of the space is adequately protected. Understanding this limit is crucial for maintaining compliance with safety standards in fire protection systems and ensuring optimal performance in emergency situations.
