What distance limitation exists for the installation of smoke alarms near ceiling fans?

The distance limitation for the installation of smoke alarms near ceiling fans is set at 914 mm (or 3 feet). This guideline is based on the understanding that ceiling fans can affect the airflow in a room, potentially interfering with the smoke alarm's ability to detect smoke particles. If a smoke alarm is installed too close to a ceiling fan, the airflow created by the fan can push smoke away from the detector, leading to delayed activation in the event of a fire. Maintaining a proper distance of 914 mm helps ensure that the smoke alarm functions effectively and reliably in detecting smoke. This regulation is crucial for optimizing safety and ensuring that smoke alarms can respond appropriately during a fire emergency.
