Smoke detectors must be located no further than how many feet apart and no more than how many feet from any wall?

The correct answer indicates that smoke detectors must be placed no further than 30 feet apart and no more than 15 feet from any wall. This guideline helps ensure optimal detection of smoke within a space, as smoke rises and spreads in unpredictable patterns, especially in larger or more complex areas.

The maximum distance of 30 feet between detectors is established to minimize the risk of a smoke plume going undetected. If detectors are spaced further apart, there is a greater chance that a fire could develop in an area that is not adequately monitored, potentially allowing it to grow before detection occurs.

The restriction of being no more than 15 feet from a wall provides additional coverage, particularly in corners or along the edges of rooms where smoke might first accumulate. Detectors too far from walls might not effectively alert occupants in those spaces where a fire could start.

These guidelines are based on safety regulations and best practices for fire prevention, ensuring that all areas of a building have adequate smoke detection coverage.
