System solutions of Gretsch-Unitas for access control

Authorised building access – Greater security and convenience

Basically, a good access control system is like a doorman who is responsible for checking tickets. It ensures security and convenience by refusing access to unauthorised persons while extending a cordial welcome to those who are authorised. An overall system that can be adapted individually to the on-site requirements always represents a high degree of building security and ease of administration combined with convenient access to the building. GU group and BKS, one of its traditional brands, is an expert partner to architects, planners and building operators, and also fabricators and security hardware dealers with the aim of providing safe and convenient access to buildings.

A building is only really secure when authorised access is reliably regulated. To achieve this, architects, planners and fabricators rely on intelligent technical solutions from the Gretsch-Unitas group of companies: as one of the international market leaders for window and door technology as well as automatic entrance and building management systems we are the competent partner for mechanical and electronic access control – from a house entrance door concept to a property's complex master key system. True to our guiding principle “Securing technology for you” we support our clients from the planning stage to implementing authorised access, whether for a new build, retrofit or reordering components.

Single-door solutions – from the mechanical key to the app

Basically, a good access control system operates like a doorman. It ensures security and convenience by refusing access to unauthorised persons while extending a cordial welcome to those who are authorised. The GU Group provides secure and convenient building access with its long-standing BKS brand – one of the leading companies for locking technology and security – to the delight of architects, planners and building operators, fabricators and lock and security equipment stores.

  • Mechanical single-door solutions – mechanical locking systems

    Safe decision: mechanical access control by BKS: durable, robust and authorised at all times: mechanical keys are the most direct form of access control. That is why handing over a key is always a special moment – especially when it's a BKS key.

    BKS satisfies the most stringent quality and security demands with high quality mechanical door protection solutions. It is these that the traditional GU group brand uses to address the most diverse requirements in the house and apartment entrance door sector.

    No matter which of the locking systems is used: every registered differ is unique. As such, BKS takes responsibility for the locking cylinders' security-related data and keys – thereby ensuring a feel-good factor.

    When it comes to BKS locking cylinders, security is the name of the game: bumping protection, featured as standard, takes care of this as well as the emergency function that prevents blocking by inserted keys. The janus system also features drilling/picking protection to prevent forced opening.

  • Feel the quality: modern reversible keys

    High expectations of security and functionality continue in the convenience of the BKS reversible key: high quality is immediately evident from agreeable haptics and intuitive use with vertical key insertion on both sides.

    High quality, copy-protected keys and registered differs with a security card ensure that access control remains in the right hands. Long patent terms on the key profile series also ensure a high degree of future-proofness.

    Is a top quality premium solution for one's own home required – or a secure solution at a good price? With its janus and helius reversible key systems, BKS can satisfy every requirement.

  • Electronic single-door solutions – the GU house entrance door concept

    Comprehensive and convenient – the GU house entrance door concept.

    Main entrance doors and apartment entrance doors are the most important conduit between one's private living space and the outside world. Designing them to be attractive while taking account of residents' individual needs sustainably secures a high level of residential amenity.

    The multi award-winning GU house entrance door concept offers a wealth of intelligent solutions for convenient and controlled domestic access: from release by means of code keypad or fingerprint scanner to opening by means of radio remote control through to integration in the Somfy building automation.

    The GU group's house entrance door concept offers residents, but fabricators as well, the benefit of a comprehensive plug-and-play package: the unique combination of multi-point lock, power transmission, control and optional swing-door drive is perfectly coordinated. This makes for easier installation and sets new standards for security and convenience at the house entrance door.

  • Ideal for modernisation and barrier-free construction

    Thanks to simplified installation and easy commissioning, the GU group's house entrance door concept is optimally suited to modernising existing house and apartment entrances. The self-locking lock with motor-driven unlocking even enables barrier-free single doors to be built in compliance with DIN 18040.

    Whether new-build, modernisation or barrier-free construction – you can always depend on the certified security of the GU house entrance door concept: meeting VdS class B, it exhibits robust security against break-in and unlocking attempts in combination with fingerprint scanner control.

Multi-door solutions – central access control and management

All doors, all functions, one system: buildings contain numerous different doors. But who is permitted to open which door? And when? The GU group's multi-door solutions make light work of setting-up, controlling and changing access authorisation. A central system covers all door types and functions in the building – thus ensuring a high degree of security and cost-effectiveness. The solutions on offer range from the purely mechanical via electronic systems to a combination of the two.

  • Mechanical multi-door solutions – master key systems

    Mechanical locking system applications

    - Double cylinders with thumbturn in order to be able to lock doors at any time, even without a key

    - Double cylinders with emergency function, e.g. for office and passageway doors

    - Cam locks for letterboxes

    - Padlock for securing containers and gates

    - Half cylinders for escape door or elevator control terminals (key switch)

    - Rim cylinders for surface-mounted rim locks on access doors, with door guard if so desired, for opening the door securely in the ajar position

    - Furniture lock cylinders for integrating office furniture with the master key system

    - Can also be combined with mechatronic systems

  • Secure buildings, secure data, secure future

    Choosing a mechanical access control system from BKS installs security, flexibility and cost-effectiveness throughout the building. This is based on the high quality and depth of in-house manufacture of the mechanical cylinders that achieve their full potential in the context of master key systems. Users and administrators of these systems enjoy an immediate benefit: instead of many keys, a single key suffices to grant access to different areas.

    The GU group and its traditional BKS brand offers comprehensive master key system planning, ordering, management and programming services covering every aspect of mechanical access control. The responsible handling of security-related data is of central importance here: the data are held by BKS and protected against unauthorised access.

    BKS mechanical solutions are the right choice because they are future-proof: you can depend on long patent terms and flexible expansion capability – not to mention reliable delivery of cylinders and prompt despatch of duplicate keys.

    Opting for a mechanical access control system in no way precludes electronic solutions. It may make sense to add complementary electronic systems, especially for security-related areas.

  • Electronic multiple door solutions

    ixalo – the electronic locking system of BKS combines a variety of electronic products and technologies into a state-of-the-art, sustainable overall system. Optionally equipped with the BKS SE technology or with RFID technology: MIFARE® (MIFARE Classic®, MIFARE® DESFire® EV1) – ixalo offers a multitude of applications for individual customer requirements. Individual designs can be created conveniently, reliably and cost-effectively by combining mechanical, and electronic locking systems.

    Energy-efficient: ixalo offers particularly low energy consumption of its products – one of the main criteria to be met by battery-operated systems. This is the only way to ensure a very large number of locking cycles.

    Secure: ixalo satisfies the highest security requirements of the EN 15684 standard for mechatronic locking cylinders by using extremely secure encoding and communication mechanisms. The security is certified by the VdS.

    Economic: locking systems are particularly cost-effective when electronic and mechanical cylinders are combined into one system. The prerequisite for this is that all cylinders, keys and transponders are managed uniformly within one software. The BKS KeyManager is thus an administration software with which electronic access authorisations can be modified at any time and can be conveniently updated locally via the release terminals.

Electronic multi-door solutions – electronic access control system

Centrally and in real time: access management with GEMOS access Managing and controlling, logging and changing access authorisations – the GEMOS access cabled access control system controls everything centrally and in real time. That makes it the right solution for efficiently satisfying complex requirements.

  • Threefold security: the GEMOS access system

    GEMOS access enables the entire authorisation and personnel data management to be activated centrally and without delay throughout the entire system: from blocking an ID card via replacement ID cards to visitors' badges. What's more, all connected doors can be centrally blocked or released.

    GEMOS access is also impressive when it comes to access management control: the current status of the doors is visualised in real time; all events related to ID cards and doors are logged automatically.

    Access control functions such as anti-passback, mantrap or double verification passage can also be implemented. Access area balancing and access sequence check, as for example parking lot management, round off the system functionality offering.

    GEMOS access security is based on three different factors – protection against manipulation, system stability and data security.

    The secure system architecture and encrypted data communication, in conjunction with the mechanical locking elements, afford reliable protection against attempted manipulation – whether of the access reader data lines, database or logbook.

    The rugged design of system components ensures extremely high availability and system stability. Duplicate network devices are tailored to individual requirements and help provide additional stability.

    Last but not least, system-wide encrypted communication and data storage, combined with sophisticated data backup concepts, ensure the greatest possible degree of data protection.

Transformation in access control

Given the wide array of access control systems, what's needed is to maintain an overview. BKS is one of the leading companies for locking technology and security and therefore a specialist in controlled building access.

But when the subject is access control, there are other important decisions to be taken as well: are we talking about one door or several? Will access be mechanical using a key or electronic? How can access authorisation be efficiently controlled.
