What is the required distance between a smoke detector and a ceiling fan blade?

The required distance between a smoke detector and a ceiling fan blade is 36 inches. This guideline is important because it helps to ensure the effective operation of smoke detectors. When a smoke detector is too close to a ceiling fan, the airflow created by the fan can interfere with the detector's ability to sense smoke particles effectively. The 36-inch distance allows for optimal airflow around the smoke detector, thereby reducing the likelihood of false alarms and ensuring that the detector operates properly when needed.

Maintaining this distance is part of best practices in fire alarm installation, enhancing overall safety in a building.
