For every building or structure of such size, arrangement or occupancy that a fire itself may not provide adequate occupant warning, a fire alarm facility shall be provided where necessary to warn occupants of the existence of fire. Fire alarms will alert occupants to initiate escape and facilitate the orderly conduct of fire exit drills. All sounding devices shall be heard over ambient noise levels and be recognized as a fire alarm signal.
