Note:

This calculator helps determine the recommended spacing between smoke detectors to ensure optimal fire detection. Proper placement is essential for early warning and effective fire protection.

Understanding the Parameters:

• Maximum Listed Spacing (D): This is the maximum allowable distance between smoke detectors as specified by the manufacturer. It is based on standard testing and fire detection efficiency.
• Recommended Spacing (S): This is the adjusted spacing that considers real-world conditions such as air movement, room layout, and obstructions. The recommended spacing is typically less than the maximum listed spacing to ensure better smoke detection coverage.

How the Calculation Works:

The recommended spacing is calculated as a percentage of the maximum listed spacing. This adjustment accounts for potential fire safety risks, such as airflow patterns and ceiling height variations, ensuring that detectors are positioned to detect smoke as early as possible.

To determine the optimal smoke detector placement, enter the **maximum listed spacing (D)** and click **"Calculate Spacing"**. The calculator will provide the recommended distance to ensure full coverage.
