What is the maximum distance that a smoke detector should be placed from the nearest wall to prevent placement in dead air spaces?

The maximum distance that a smoke detector should be placed from the nearest wall is 4 feet to prevent placement in dead air spaces. Dead air spaces can hinder the effectiveness of a smoke detector, as they may create areas where smoke doesn't reach the detector in a timely manner, potentially delaying alarm activation during a fire. By maintaining a distance of no more than 4 feet from walls, you help ensure that the detector can effectively sense smoke entering the area from various angles, thereby providing a quicker response in the event of a fire. This guideline is crucial for optimal safety and compliance with fire safety regulations.
