At what height above the floor must a smoke detector be installed in sleeping areas?

1. At least 4 inches

2. At least 6 inches

3. At least 12 inches

4. At least 16 inches

The correct answer is: At least 12 inches

The installation height of a smoke detector in sleeping areas is critical for ensuring it operates effectively. The correct choice indicates that a smoke detector should be installed at least 12 inches from the ceiling. This height helps ensure that the detector functions optimally by allowing smoke to accumulate and activate the device without obstruction. Proper placement also minimizes the risk of false alarms, which can occur if the detector is too close to the ceiling where warmer air may hinder smoke detection. Other options suggest various heights, though none align with the best practices outlined in safety codes and guidelines. Staying within the recommended installation range enhances the reliability of the smoke detector in alerting occupants to potential fire hazards while promoting overall safety in residential environments.
