About this detail

This diagram details the required mounting heights and spatial clearances for fire alarm notification appliances, smoke detectors, heat detectors, and control panels relative to finished floors and structural elements. Wall-mounted devices such as pull stations are dimensioned at forty-eight inches maximum, while audible and visible appliances are positioned between ninety and ninety-six inches. Smoke and heat detectors near beams, sloped ceilings, and supply air diffusers are assigned specific geometric clearances and spacing adjustments per NFPA 72 guidelines.
