What is the recommended distance between smoke detectors?

The recommended distance between smoke detectors is typically 30 feet. This guideline is based on ensuring that smoke detectors are adequately spaced to provide effective coverage throughout an area while minimizing the risk of undetected smoke accumulation. Spacing them too far apart can lead to gaps in coverage, where smoke may not reach a detector quickly enough to alert occupants in the case of a fire.

Maintaining this distance helps ensure that the detectors are responsive and can effectively alert people in a timely manner. It is also important to consider factors such as the layout of the building, the presence of walls or obstructions, and the specific recommendations of the smoke detector manufacturer. For example, smoke detectors should be installed in every sleeping area and on every level of a home in addition to the 30-foot guideline for rooms where they are not located directly adjacent.

The other distances mentioned do not align with standard recommendations and may leave significant areas unprotected.
