What is the EN 12101-2 standard? EN 12101-2 is a European product standard with the title “specification for natural smoke and heat exhaust ventilators” Since 1. September 2006, all natural smoke and heat exhaust ventilators must be CE marked according to the European product standard EN 12101-2. What is the EN 12101-10 standard? EN 12101-10 is a European product standard with the title: “Smoke and heat control systems – Power supplies” All VELUX power supplies for smoke ventilation are in compliance with EN 12101-10. How is a product CE-marked in accordance with the EN 12101-2 standard? The natural smoke and heat exhaust ventilator should be classified in regards to: Reliability: A requirement for the number of cycles the ventilator can operate safely Snow load: A requirement for the maximum snow load to ensure full function Low temperature: A requirement for the minimum room temperature to ensure function Wind load: A rzequirement for the maximum wind suction that the ventilator can withstand without compromising the function Heat exposure: A requirement for the temperature, under which the ventilator will maintain its function during 30 minutes of heat exposure Aerodynamic free area: A requirement for efficiency of the ventilator for all wind direction The certification tests must be carried out by a certified test institute Window and smoke ventilation operator must be tested and certified as one unit The certification must be made by a notified certification agency The natural smoke and heat exhaust ventilator must be CE marked and the certification values must be displayed at the product Does the EN 12101-2 standard cover sloped roofs? The standard lays out requirements for natural smoke and heat exhaust ventilators independent of whether they are placed in sloped or flat roofs. Do VELUX smoke ventilation products live up to the newest EN product standards? VELUX smoke ventilation windows are CE marked and have been tested in regards to the parameters of EN 12101-2 All VELUX smoke ventilation products are updated in accordance with the harmonized standards in the EN 12101 series regarding smoke and heat control as soon as the standards come into force Where is the proof for compliance with EN 12101-2 found? A product for natural smoke and heat ventilation cannot be CE-marked if it has not been classified in compliance with the EN 12101-2 product standard A declaration of conformity is delivered with VELUX smoke ventilation windows which includes the certification values Using VELUX roof windows, what should be ordered to have a certified system for natural smoke and heat exhaust ventilation? A VELUX smoke ventilation window including wind deflector should be used when there are requirements for an aerodynamic free area OR: A VELUX smoke ventilation window (excluding wind deflector), should be used when there are requirements for a geometric area of ventilation AND: A VELUX control system for simultaneous operation of up to four smoke ventilation windows or linked with more VELUX control units KFC 210/220 Or any control system for smoke ventilation that is applicable and approved for use with VELUX GGL/GGU smoke ventilation windows Are VELUX smoke ventilation windows available in different sizes and variants? VELUX smoke ventilation windows are delivered in several VELUX standard sizes enabling correct specification for a variety of applications (adapt to local offerings) A choice can be made between pinewood finish and white polyurethane finish Why does VELUX use a centre pivot window that opens 90 degrees? The centre-pivot symmetry at a 90° opening angle makes the effectiveness more even, meaning that the centre-pivot roof window allows for an effective smoke and heat exhaust independent of the wind direction. This means that a wind sensor is not necessary and that only one VELUX smoke ventilation window often is enough to meet the demand. According to the EN 12101-2 product standard, the effectiveness of the natural smoke and heat exhaust ventilator must be measured under wind exposure from different angles Is it possible to use the smoke ventilation system for comfort ventilation? Yes: VELUX smoke ventilation windows have passed the requirements of the reliability test in the EN 12101-2 standard, which requires that the window can operate more than 10.000 cycles For comfort ventilation, the window opens up to max. 200 mm (recommended) , making it compliant also to the safety standard EN 60335-2-103 The characteristics of the centre-pivot window in relation to comfort are favourable since the sash in a comfort-opened window protects against rain, falling leaves etc. What is the maximum ventilation area, which can be obtained? A VELUX control system (KFX 210) can be used to operate up to 4 smoke ventilation windows, giving a possibility to create a smoke geometric area of 6-5 m2 or an aerodynamic free area of almost 3 m2. More control units (KFC 210/220) can be linked to operate up to 80 VELUX smoke ventilation windows, if required. Does the smoke ventilation system protect against power failure? An integrated battery back-up in the control system means that the system will still respond for 72 hours in the event of power failure How is a VELUX smoke ventilation window installed? The VELUX smoke ventilation window is installed in roofs with pitches between 15-90°. For roof pitches between 60-90° special requirements may apply. Please check your local requirements. For a quick and easy installation, the compact smoke ventilation operator has been pre-mounted on the sash of the roof window, making it invisible when the window is closed Two discrete gas springs are easily mounted on the window to enable a stable and fast opening A wind deflector is installed depending on the application Is it possible to replace previously installed VELUX smoke ventilation operators? In case of defect, the VELUX smoke ventilation operators can be replaced. Is it possible to connect the VELUX system to external alarm systems? Yes: The VELUX smoke ventilation system can be controlled by an external alarm system A module for connection to external alarm systems is included in the control units KFC 210/220 Does VELUX offer services related to smoke ventilation? VELUX also provides assistance with system installation, commissioning and annual servicing (adapt to local offerings) For which applications can a VELUX smoke ventilation system be used? The VELUX smoke ventilation system is a very flexible and cost efficient solution suited for a variety of applications, ranging from staircases in apartment buildings to large commercial buildings VELUX smoke ventilation solutions are effective in all roof window applications, providing great flexibility in positioning the window on the roof How can the performance of different smoke and heat exhaust ventilators be compared? Information on the performance must be indicated on the products itself and on the accompanying CE declaration or certificate for compliance The CE marking ensures that the performance can easily be compared Compliance with EN 12101-2 can be obtained only when the products are labelled with a reference to the standard, and the version of the standard used for certification is written on the product When should a smoke ventilation window including wind deflector be installed? Wind deflectors should be used when legal requirements for smoke ventilation address the aerodynamic free area. This may depend on the application and the local legislation. When should a smoke ventilation window excluding wind deflector be installed? A VELUX smoke ventilation window excluding wind deflector is used when legal requirements for smoke ventilation address only the geometric area Can VELUX smoke ventilation windows be used in flat roofs? The smoke ventilation windows can be installed in roofs with pitches between 15 and 90°. In flat roofs 0-15°, the windows are installed using a VELUX ECX flat roof curb or a VELUX CSP flatroof smoke ventilation window is used.
