What is a requirement for the placement of a fire alarm in relation to a ceiling fan?

The requirement for the placement of a fire alarm in relation to a ceiling fan is that it must be placed at least 3 feet away from the fan. This guideline helps to ensure that the fire alarm can properly detect smoke and heat without interference from the airflow created by the fan. When an alarm is placed too close to a ceiling fan, the fan's operation could potentially disrupt the airflow needed for smoke to reach the detector, which might delay activation and compromise safety. Maintaining a distance of at least 3 feet helps to ensure that the alarm functions effectively and can provide timely alerts in the event of a fire.

The other options do not adhere to best practices for fire alarm placement. For instance, placing an alarm directly below the fan could lead to similar issues with airflow interference, while attempting to position an alarm to touch the fan blades would create further risks and would not meet safety standards. Therefore, the requirement for maintaining a distance of 3 feet is essential for effective fire alarm operation.
