Wall mounted audible notification appliances shall have their tops above finished floor at not less than how many inches and below the finished ceilings at distances not to exceed how many inches?
Correct Answer:
90 inches; 6 inches
Explanation:
The placement rule tests mounting height for wall-mounted audible appliances to balance audibility with practical installation. The top of the device must be at least 90 inches above the finished floor so the unit sits above most people and furniture, reducing obstruction of the sound. At the same time, it should be located not more than 6 inches below the finished ceiling, keeping the unit close enough to the ceiling to achieve the intended acoustic distribution and coverage. This combination—top at or above 90 inches and no more than 6 inches below the ceiling—ensures consistent audibility throughout the space.
