Air inlet systems
In the event of a building catching fire, air inlet systems provide the necessary "air flow power". This way fire smoke can escape. Here, the coordinated interaction of air inlet and exhaust air solutions is crucial.
Smoke and heat extraction system (SHEV) save lives in case of a fire
… gases and heat can quickly be drawn outside via an smoke and heat extraction system (SHEV system). In case of a fire, smoke and heat extraction systems protect against hazardous flue gases Rooms can quickly fill with toxic fumes in the event of a fire. There’s no fire without smoke: 10 kg of paper or cardboard releases up to 10,000 m³ of fumes when burned Even a burning waste paper basket quickly fills an office with smoke from floor to ceiling. When fire breaks out, it’s the smoke that’s the biggest danger to the people caught up in it, and the fire-fighters. The developments are dramatic: The first effect of smoke is impaired visions - in less than three minutes. People lose their bearings and begin to panic. Escape routes are no longer recognisable. Then comes carbon monoxide (CO). Concentrations of this gas rises rapidly during a fire. Inhaling carbon monoxide leads to headaches, symptoms of poisoning, unconsciousness, and ultimately death. Smoke-free escape and rescue routes thanks to SHEV Toxic fumes must be removed from the building as quickly as possible. Smoke extractors are installed to provide natural smoke extraction. SHEV smoke ventilation systems can be activated automatically (via smoke detectors) or manually (via SHEV buttons). They open ventilation openings like SHEV windows or fanlights . These draw fumes and heat energy away from the building. Escape routes remain smoke-free and fire-fighters are able to intervene quickly, precisely where they are needed. LEARN MORE ABOUT EMERGENCY EXIT PROTECTION Effective smoke extraction requires air inlet openings Smoke and heat extraction systems are dependent on smoke being extracted from above a supply of fresh air from below. These air inlet openings support fire-fighting measures Air inlet systems provide: increasing thermal drive, resulting in fumes being drawn more quickly through SHEV windows or openings in the roof (chimney effect), creating a low-smoke layer along the bottom part of the room to provide a clear view of escape and rescue routes, reducing the amount of fumes and explosive smouldering gases as a result of cleaner combustion, reducing the heat, enabling fire-fighters to get closer to the fire. GO TO GEZE AIR INLET SYSTEMS Tips for planning and assembly of smoke and heat extraction system air-Inlet doors This is how effective smoke and heat extraction works in the event of a fire: GEZE expert Dr. Dominik Landerer explains the central role of air inlets for effective smoke and heat extraction systems (SHEV) in buildings and provides practical tips for planning and implementing SHEV air-Inlet doors. MORE ABOUT SMOKE AND HEAT EXTRACTION SYSTEM AIR-INLET DOORS Smoke vent, heat extraction, smoke and heat extraction systems and pressure ventilation systems Smoke extraction (NRA, NRWG, MRA) Heat extraction Smoke and heat extraction systems Pressure ventilation systems Smoke extraction (NRA, NRWG, MRA) Heat extraction Smoke and heat extraction systems Pressure ventilation systems A smoke vent is part of preventative fire suppression and ensures smoke extraction in case of a fire. The objective is a stable layer of air with little smoke near the floor so that escape and rescue routes can be used safely. An open smoke extraction also carries away heat from the fire. This means that the load-bearing behaviour of load-bearing or separating construction components is extended considerably. For this reason, the terms smoke extraction and smoke ventilation are often used synonymously. Smoke extraction is designated as natural smoke extraction if it works via natural thermal lift, without additional ventilation drives (such as ventilators). Natural smoke and heat extraction system (NSHEV) include, for instance, windows, skylights, ventilation blinds that open automatically in case of a fire and help dissipate smoke and hot gases out of a building. In accordance with DIN EN 12101-2, a natural NSHEV is a natural smoke and heat extraction system designed for installation in buildings as part of a smoke ventilation system. A natural SHEV consists of a window and its associated components (profiles, seals, door fittings), the infill (e.g. glass, panels), and the drive system with its associated components (drive, consoles, fittings). A mechanical smoke extraction (MRA) works with a motorised drive, such as with smoke extraction fans. Smoke can be removed either with or without ventilation ducts. Materials in wall or roof areas are described as heat extraction (WA) if they melt at higher temperatures or destroy themselves in the process. Openings created in this way enable heat from the fire to escape from the burning room. The energy drawn from the room on fire is now not available to further heat load-bearing or divisional construction components, for example. As a result, these construction components reach their critical temperature at a later point in time. Heat extraction thus extends the load-bearing behaviour of such components. Heat extraction generally becomes effective when the fire has taken hold for some time. Fumes are also drawn out via the openings. But this is too late in terms of protecting people and fighting the fire. S0 heat extraction is not the same thing as smoke extraction! The term automatic opening vent and the technical systems that performs this function are both abbreviated with AOV. Natural automatic opening vent (AOV) consist of the following: the AOV smoke vent, e.g. windows, fanlights, skylights in roof, each with drive system the control and power supply (AOV panel) the triggering element (such as smoke detectors, AOV system button) the fresh air supply (e.g. via open windows or doors) smoke screens if needed (to divide up larger rooms) Safety stairwells are required in pressure ventilation systems: according to the Model Building Code (MBO Sec. 33), a safety stairwell must be designed so that fire and smoke cannot get inside. Pressure ventilation systems and smoke protection pressure systems ensure they remain free from smoke. Functions of SHEV Smoke and heat extraction systems (SHEV) serve primarily as preventive fire protection to safeguard people. They also have additional functions, however: Protecting people keeping smoke out of rescue routes Environmental protection reducing environmental damage Property protection maintaining the building structure Active rescue Minimising damage caused by fire extinguishing activities Fire-fighting support Passive rescue Minimum use of extinguishing agents Ventilation of the fire Localisation of the fire Minimisation of the thermal load Smoke and heat extraction SHEV enables escape, rescue, and fire-fighting measures. © GEZE GmbH Smoke and heat extraction Without SHEV, toxic fumes and heat will remain in the building. © GEZE GmbH GEZE electric SHEV and ventilation systems brochure You can download our brochure on SHEV and ventilation systems here: GEZE ELECTRIC SHEV AND VENTILATION SYSTEMS (PDF |
Smoke and heat extraction solutions for the Dresden Frauenkirche – GEZE
… gases and heat can dissipate in a controlled manner, allowing people to leave the church in an orderly fashion, and rescue operations to proceed unhindered. Historic windows with tailor-made window drive GEZE E206-RWA electric linear drive on a semicircular arched window in the Frauenkirche. © MM Fotowerbung / GEZE GmbH Modern smoke and heat extraction systems generally consist of at least three components: an opening system, in this case the windows of the Frauenkirche an emergency power supply control unit a fire button Specific technical adjustments were required to reconstruct the church in its original design as far as possible. Typically, smoke and heat extraction systems run on a 24 V working voltage. The smoke and heat extraction system drive on the high windows, however, could only be supplied with voltage through a long supply line. For aesthetic reasons, small line dimensions needed to be used, requiring only minimum recesses on the interior walls. A customised solution was in order. In coordination with the German Association for Technical Inspection (TÜV), the planning company opted for a well-proven GEZE smoke and heat extraction system that works on 230 V power. The windows in the upper part of the church were equipped with two GEZE E206 window drives each because of the weight of the bottom-hung and top-hung leaves. The window technology was included in a special construction whose design integrates discreetly into the building. Reliable smoke extraction, even during a power failure One key safety aspect that all smoke and heat extraction systems must fulfil is their ability to work independently of the power grid. 24 V systems ensure this using a rechargeable battery integrated into the smoke and heat extraction system emergency power supply control unit. Since the smoke and heat extraction system in the Frauenkirche used a 230 V variation, the GEZE E260 N 2/1 emergency power supply control unit was installed in a special version. The entire smoke and heat extraction system is connected to the on-site backup power unit to ensure grid-independent function in any situation. Overall, the Frauenkirche in Dresden is another successful example of how highly modern GEZE smoke and heat extraction systems can be integrated into historical buildings with specific requirements.

Building safety for people and values
… gases from the building and keep them away from escape routes. Mechanical smoke extraction systems discharge the flue gases via fans. Natural smoke extraction systems use the thermal buoyancy principle to transport smoke directly to the outside via openings or windows. Access control and emergency exit protection Building safety also means protecting buildings, rooms, data and property against unauthorised access. It means granting only authorised persons access to certain areas in buildings or protected areas, usually sensitive areas such as computer centres, clean rooms, company areas, airports, banks, etc. The operator determines who is allowed to go where and when – even at specific times. In an emergency, everyone must also be able to get out – but not everyone must be able to enter. This is where emergency exit protection systems come in: they manage the balancing act between controlled access and emergency opening with alarm (via emergency button) in the event of an emergency. Burglar resistance due to resistant doors and windows Although access control already keeps many unauthorised persons out, building safety is also about mechanical burglar resistance. Doors and windows must provide adequate protection against burglary, for example. Depending on the goal in protecting a particular area, decisions can be made in terms of the appropriate design of doors and windows. According to DIN standard EN 1627:2011-09 "Doors, windows, curtain walls, lattice elements and closures - Burglar resistance - Requirements and classification", the components are classified in resistance classes (RC). Doors according to the RC1 to RC4 classifications offer higher protection against burglary due to their stability. Notification systems A safety concept is completed by detecting and monitoring measures. These ensure that both damaging events and accidental or intentional attempts to overcome protective and safety measures are detected as early as possible. For example, smoke detectors can detect fires at an early stage and trigger corresponding alarms. Burglar alarm systems, for example, show break-in attempts, while door guards at emergency exits draw attention to unauthorised use by means of an alarm signal. Doors as the most important aspect when it comes to building safety Important for building safety: multifunctional door © Jürgen Pollak / GEZE GmbH Doors can serve as building access, emergency exits and protected connections to other rooms with different functional areas. They have an important job to do in terms of building safety. They also meet other technical demands in terms of fire protection, sound insulation and accessibility. As a result, automatic doors in particular have developed into complex systems with intelligent drives. Multifunctional doors fulfil the following functions: access control fire and smoke alarm escape door control system Protection by sensors, e.g. presence and movement detectors If the door systems are integrated into building automation or building management systems, their operating status can be displayed and controlled remotely. GEZE door solutions for your safety GEZE offers high-performance safety solutions for automatic door drives. These are adapted to the respective specific demands and individual escape route concepts - from the door control unit as a stand-alone solution to system solutions that combine individual safety demands in an intelligent system.

This is regulated, for instance, in state building regulations as well as in the DIN standards “DIN 18232-2 Smoke and heat control systems - Part 2: Natural smoke and heat exhaust ventilators; design, requirements and installation” and DIN EN 12101 “Smoke and heat control systems”. LEARN MORE ABOUT SMOKE AND HEAT EXTRACTION SHEV solution specially tailored for the DFB football hall The smoke and heat extraction systems in the indoor soccer court make use of thermal uplift. © Getty Images The smoke and heat extraction systems in the DFB indoor football court make use of thermal uplift through openings in the top of the façade, in order to ensure quick smoke venting and targeted heat dissipation. Due to the enormous volume of the room, a high air vent opening was needed here. One unique challenge were the 22 SHEV fresh air openings in the DFB indoor football court, as they are located at a height of 18 meters. In addition, each of the approx. 5m² smoke and heat extraction intake air elements need to be able to open and close quickly and reliably in case of a fire, even under wind pressure. We created a customised smoke and heat extraction solution to overcome this challenge: Our E 3000 Syncro heavy-duty spindle drives are particularly well-suited to use in heavy façade and roof window areas, since they have very high push and pull forces. In addition, brackets produced specifically for the DFB indoor football court transmit the loads into the building structure. Now, two type E 3000 Syncro spindle drives per panel ensure the SHEV fresh air openings open and close reliably according to the DIN 1055-4 wind loads. Advantages of the E 3000 spindle drives Robust and corrosion-resistant spindle drive with built-in end position damping Specially suited for very heavy windows in the roof area Tested as a natural smoke and heat exhaust ventilation device according to DIN EN 12101-2.

… gases spread quickly when a fire breaks out. It is only later that the temperature increases. As far as possible, smoke detectors should generally be used for RWA systems. In areas where disruption such as steam, dust or operation-related smoke development (workshops, kitchens) occurs, it may, however, be sensible to use heat detectors rather than smoke detectors. Terminating resistor for line monitoring There must be a 10 kΩ terminating resistor built into the base GC 160 B of the last smoke detector in a line. The resistor is included with the control unit.
Preventive fire protection in football stadiums – GEZE
… gases render emergency exit signs unrecognisable in seconds. Efficient smoke and heat extraction systems (RWA) are essential in safeguarding escape and rescue routes. In the Cape Town Stadium, still known as the 'Green Point Stadium' during the 2010 World Cup, an ingenious smoke and heat extraction system (RWA) by GEZE extracts smoke as soon as it occurs; the warm smoke rises through thermal momentum, while fresh air streams in through air supply openings (windows and doors) in the lower area of the stadium. GEZE has equipped the exhaust air windows with fully developed electric RWA system drives. As well as their smoke and heat extraction function, the systems also help with the daily ventilation of the stadium. The emergency power supply control unit is the ‘brain’ of the RWA system: it takes over the supply, coordination and monitoring of all the connected opening systems and alarm components. GEZE door closers: safety and convenience in all areas A whole host of visual and technological solutions have been realised in the entrance areas and interior doors of both stadiums with the GEZE door closer portfolio. For example, GEZE overhead door closers with integrated closing sequences for fire and smoke protection doors help to close the door leaves in the right order, so that two swing door leaves close tightly and act as a safe fire closer. An electromagnetic hold-open function for the door leaves, with variable opening angles, guarantees that large numbers of spectators can pass comfortably through the stadium doors. Together with a smoke switch, the detection mechanism contributes to preventive fire protection; in the event of a fire, the hold-open function is suspended and the door closes automatically. The floor springs by GEZE are particularly unobtrusive; they are almost invisibly integrated into the floor, making them perfect for the heavily-frequented stadium doors. Naturally, the door closers are also suitable for use with fire protection doors. Elegant door convenience for exclusive hotels State-of-the-art window technology in an exquisite design: the Oyster Box Hotel in Durban. It is not only planners and operators for football stadiums who rely on the first-class quality of GEZE door and safety solutions. The various door closers from the GEZE product series are also used in the 5-star luxury resort, the Oyster Box Hotel. The magnificent building in the north of Durban which overlooks the Indian Ocean, was reopened at the end of 2009 following several years of renovation. World Cup fans were able to enjoy all kinds of comfort here, before sharing the excitement at the matches in the nearby Moses Mabhida Stadium - against an acoustic backdrop of vuvuzelas. Discreet elegance: GEZE door closers ensure ease of access The traditional colonial architecture of the Oyster Box Hotel forms an appealing contrast to its contemporary interior. The perfect environment for the integrated GEZE Boxer door closer, which is completely integrated into the door leaf and offers an incomparably discreet door appearance. The 15 on Orange Hotel - named after its location in the centre of Cape Town - was also renovated just in time for the World Cup. It is not only the elegant, consistent aesthetics of the GEZE door closer that come into play in the city's consummate boutique hotel. Automatic designer glass sliding doors also help to shape the inviting, transparent atmosphere at the 15 on Orange hotel.
