GEZE’s wireless solutions for hold-open systems in the Magdeburg cathedral

… Stefan Dauth / GEZE GmbH Fire protection in Magdeburg Cathedral – with GEZE’s wireless solutions for hold-open systems Magdeburg’s imposing cathedral is an important city landmark and a popular destination for visitors from far and wide. In a building that is so historically important and versatile, a comprehensive approach must include modern ease of access, fire protection and monument protection. Integrating these factors in existing structures subject to heritage protection is a real challenge. GEZE’s hold-open systems, wireless extensions and wireless smoke detectors ideally address these challenges.

At the same time, building work on historical monuments must adhere to the applicable monument protection regulations when using fire protection doors to set up fire sections and installing additional smoke alarm systems. What’s more, there should be as little interference as possible in the architecture and structure of protected historical buildings. The modernisation and fire protection measures commissioned by the Foundation for Cathedrals and Castles in Saxony-Anhalt (Stiftung Dome und Schlösser in Sachsen-Anhalt) were planned by Sußmann + Sußmann AR Magdeburg and constructed by Tischlerei Wagner, whilst the hold-open systems were installed and approved by Kötter & Siefker Bernburg. When modifying existing buildings, it is hard to think of everything, especially when the old plans do not show all the details. The ceilings and walls of the protected cathedral had to remain untouched. Wireless solutions were needed to save on work and costs. In addition, alternative, unapproved expansion solutions were to be avoided. GEZE’s secure, certified and complete system allowed it to stand out on this project. David Jungbluth, Official Expert and Branch Manager at Kötter & Siefker Berneburg The challenge of the cathedral: high ceilings require additional ceiling-mounted detectors The so-called Carpenter and Stonemason Room, which was long used as a storage area for parts and minor restoration works (jambs, statues, stucco areas, pillars etc.), is to be transformed into an exhibition and event space in future. The high number of visitors expected to use the space requires a possible hold-holding open of the doors. As the Carpenter Room is also planned as a separate fire protection section, the fire protection doors need to close automatically in case of alarm. Due to the extremely high ceilings, two additional ceiling-mounted detectors are required here. Cables would need to have been concealed in the joints, which would have meant significant additional expenses in the joint area as well as some chiselling and slitting work. Monument protection issues would have required complex and time-consuming legal and regulatory approvals. Wireless extensions Ideal for buildings with protected monument status: wireless extensions for hold-open systems. © Stefan Dauth / GEZE GmbH I am very familiar with Magdeburg Cathedral and its protected historical structure – after all, I conduct cathedral tours myself. Whilst the Schörghuber wooden fire protection doors are a good fit within the visual surroundings, technical elements such as door closers and smoke alarm systems present a challenge. GEZE’s discreet hold-open systems with wireless modules in conjunction with the wireless ceiling-mounted detectors are the ideal solution here, because no cable connections are required between the lintel-mounted and ceiling-mounted detectors. Wagner, Master Carpenter The wireless extension solution for GEZE’s hold-open systems had two other decisive pricing advantages: - Cost factor: eliminates the cost of laying cables - Time factor: reduces installation time Go to Wireless KIT GC 170 Hold-open systems in the organ loft provide quiet ease of access and fire protection A good example of the interplay between ease of use and modern fire protection measures can be seen in the access to the organ loft, which can be reached via two doors. One side serves as an entry, the other side as an exit – meaning there is no scramble when the church choir comes and goes. Because of the many comings and goings at certain times, it is crucial that the doors close quietly and can be kept open if necessary – after all, a solemn service should not be disturbed by slamming doors. At the same time, the hold-open systems must automatically close the fire doors in case of fire to prevent the spread of smoke and flames. It was particularly important to set up new fire protection closers for the organ loft, as only normal building doors were used here previously. There were no fire protection closers or other fire protection measures, only fire alarm systems. Two new wooden fire protection doors were manufactured by Tischlerei Wagner from Körbelitz, Germany. GEZE TS 5000 R guide rail door closers with an electrical hold-open device, continuously adjustable closing force and integrated back check ensure that the doors close quietly and are kept open if necessary. The smoke switch control unit integrated in the hold-open system makes sure that the doors close automatically in case of fire.

The previous church on the site had nationwide significance as the burial place of the Holy Roman Emperor Otto the Great. The original cathedral was destroyed by fire in 1207. The complex construction of the Gothic cathedral began in 1209, and the dedication took place in 1363. The elaborate church construction took over 300 years. In 1520, the two imposing church towers were completed – the north tower and its outdoor platform can be visited as part of guided tours. The number of visitors shows just how important the historic building is today: in addition to churchgoers attending services in the present Protestant parish church, more than 100,000 tourists visit the impressive Gothic building every year.

The right swing door drive for your demands

… Stefan Dauth / GEZE GmbH At GEZE, you will find the right swing door drive for your automatic door Swing door drives are the good little spirits of automatic swing door systems. They unobtrusively ensure that doors open and close smoothly. Thanks to them, thereʼs no need to press a handle or switch when entering a building – and, thanks to activation devices and sensors, the doors open all by themselves the moment they detect us. An invaluable benefit in terms of convenience, accessibility and hygiene. The range of swing door drives is just as diverse as the range of applications for automatic doors. We provide you with an overview of our automatic swing door drives. Of course, you can also contact us personally at any time so that we can work together to find the right solution for you. Accessibility, convenience, security, energy efficiency – GEZE swing door drives satisfy numerous demands Functional and aesthetic: Powerturn swing door drive in the Dubai Opera building. © Nicolas Thome / GEZE GmbH Especially in public building projects, accessibility is particularly important in the building code. Because of this, automatic doors are predominantly used in this area. Also with regard to fire protection regulations automatic swing doors impress with their characteristic features. Because in the event of a fire, for instance, automatic doors close automatically or, thanks to sensory protection, also recognise obstacles in the door. When selecting the right swing door drive, the type of swing door, the installation situation and the resulting demands are decisive. The size, weight and material of the door must be taken into account. Here, for instance, frameless all-glass doors demand different sliding panels than heavy single-action doors made of steel. The location of your automatic door also plays a major role: in a shopping centre, for example, exiting the building only may be called for after a certain time of the day, making it impossible to enter from the outside. Does the swing door drive design be adapted to the ambience and be as invisible as possible, for example at the entrance to a hotelʼs foyer? Or does the automatic swing door have to satisfy special safety aspects, such as when used at an airport? For instance in a hospital, hygiene aspects can also demand the use of special swing door drives. More about our swing door drives For all these different usage scenarios, we offer you a large selection of automatic door operators – and with numerous variants. But don’t worry, we won’t leave you to make the decision alone, and are happy to advise you. More about our individual swing door solution Four questions to find the right swing door drive The demands of automatic swing doors are complex, and the right drive plays a key role. As a step-by-step guide to help you as a planner to find your optimal solution, we have listed four questions below to provide you with initial guidance in your selection. Which general demands must the swing door satisfy? With their numerous varieties, our swing door drives offer the matching solution for every kind of automatic swing doors. Generally speaking, GEZE automatic door drives distinguish themselves in the following points: GEZE ECturn : Small and discreet, these swing door drives are suited particularly well for smaller interior and entrance doors, especially in the private sector. GEZE ECturn Inside : It can be integrated into the door leaf or frame, is almost invisible and does not affect the door design. GEZE Slimdrive EMD : This drive type scores with enormous performance combined with low-noise operation. GEZE Powerturn : This powerful swing door drive is a real all-rounder; it is particularly suitable for increased demands on functionality and for especially large and heavy doors. How high is the footfall frequency of the automatic swing door? The so-called footfall frequency is an important indicator when it comes to the planning of the swing door drives. It immediately influences the questions regarding door width and the number of leaves. It is a good idea to consider the answer to this question. In this regard, the following table will help you. How large, how heavy and of which material are the door leafs made? Whether single or double leaf – with the selection of the correct swing door drives, the respective leaf weight is of key importance. Here, we cover the complete range up to 600 kg with our various drive series. What is more, the material used in your swing door plays an important role for the automatic door drives: with the subtle ECturn, it is even possible to automate frameless all-glass doors. Which safety aspects are in the foreground? Where will you install your swing door, what functions should it satisfy? Is it intended as both a fire protection door and an escape and rescue route ? Do any special hygiene aspects need to be taken into account? The respective safety demands also depend on the answer to these questions. And thus also the choice of the appropriate swing door drive as well as the accessories such as sensors, activation devices, protection, etc. We will be happy to help you clarify any questions you may have.
