264 Preventive fire protection in multi storey buildings The aim of fire protection in ducting is to prevent the spread of fire from room to room and floor to floor in a building. Building design specifies compartments in the building protected by fire rated walls, floors and ceilings. However, it is necessary to make openings in these walls, ceilings and floors for services. Helios offer a range of options with certified fire ratings to maintain the integrity of the fire wall etc. Fire damper ELS-D Fire protection element for ventilation ductings according to DIN 18017. For vertical installation in ducting directly below the ceiling. With installation of the ELS-D, the use of further classified fire protection elements on air intakes or extracts is unnecessary. Ideal for use in installation shafts with mixed mains (also with combustible mains). Approved for single and central ventilation systems as well as for intake and extract systems. Maintenance free. Details see page 270 New fire protection system BSH for ventilation systems K 90-DIN 18017. Cost effective and maintenance free. Prevents the transmission of fire and smoke. Installation in ceiling sector through insertion in the vertical main ducting (spiral ducting). T-pieces are unnecessary because of model range (with 0, 1 or 2 side spigots). Ideal for use in installation shafts with mixed mains (also with combustible mains) in combination with single ventilation units (ELS).
