2020 FBC - Building, 7th edition > E Florida Standard for Radon-Resistant New Commercial Construction > E401 Active Soil-Depressurization Systems > E402 System Components > E402.5 Fan-Failure Indicator
JUMP TO FULL CODE CHAPTER
Each soil-depressurization system shall have a failure indicator labeled with the words "RADON REDUCTION SYSTEM FAN-FAILURE INDICATOR" mounted so as to be conveniently visible to the building occupants. The fan-failure indicator may be either a visual device consisting of a light of not less than 1/5 footcandle (2 lux) at the floor level, or an alarm that produces a minimum 60 db audible signal. The indicator shall be made to operate automatically when the pressure inside any radon vent pipe fitted with an operable fan is less than 0.40-inch water column (100 pascals) lower than the air pressure inside the building.
