What is the minimum distance between smoke detectors allowed in a continuous covered area, according to fire codes?

The minimum distance between smoke detectors allowed in a continuous covered area, according to fire codes, is 20 feet. This requirement helps ensure that the detectors are spaced appropriately to effectively detect smoke and provide adequate coverage. Proper spacing minimizes the risk of smoke from a fire being missed by too few detectors placed too far apart. It also enables the detectors to react swiftly to any potential alarm conditions, ensuring safety in the protected area.

In continuous covered areas, such as hallways or large rooms, maintaining this 20-foot distance helps promote the efficiency of the smoke detection system while adhering to the guidelines established in national fire protection standards. This spacing strategy is critical in preventing any gaps in smoke detection coverage, which could potentially compromise the safety of occupants in the event of a fire.
