    What is the .7 rule for smoke detectors?
    The ". 7 rule" for smoke detectors refers to the guideline that smoke detectors should be placed so that no point in a room is more than 0.7 times the listed spacing distance from a detector. This ensures adequate coverage, as smoke may not travel directly to a detector, especially in larger or oddly shaped rooms.Jan 18, 2026
