What is the maximum nominal spacing between smoke detectors?

The maximum nominal spacing between smoke detectors is primarily based on the manufacturer's guidelines and national fire alarm codes, which typically allow for a spacing of up to 30 feet between detectors. This distance helps ensure that smoke can be detected effectively, as smoke particles will have adequate time to travel to the detector before they spread throughout the area.

Spacing detectors further apart than this could lead to delayed detection of a fire, which could jeopardize safety. In addition, the arrangement of smoke detectors must account for factors such as ceiling height, airflow patterns, and the presence of obstructions that could inhibit smoke movement, but the benchmark of 30 feet serves as a standard operational guideline.

Understanding this maximum distance is crucial for maintaining safety in a building and ensuring compliance with fire safety regulations.
