Equipped for the Future. DORMA System Solutions Reconcile Safety, Security and Convenience
 DORMA System Solutions Reconcile Safety, Security and Convenience
Having inaugurated its new "Terminal 2", Flughafen München GmbH, the Munich airport authority, has put in place an important building block for the growth both of the airport and of the entire economic region of southern Germany.
The glass cube of Munich's new Terminal 2, which went into operation on 29 June 2003 – approx. three years after the start of the building work – offers a generous and spacious aspect and will result in passenger capacity increasing to 50 million people per year. The highly modern terminal jointly constructed by Flughafen München GmbH and Deutsche Lufthansa reduces the transit times of passengers of Lufthansa and its partner companies to a mere 30 minutes.
However, it is not only in this respect that the new terminal sets new standards. It also excels in terms of its ultra-modern technical equipment which has, inter alia, successfully reconciled the otherwise contradictory requirements of safety and security.
One of the major contributors to this success has been the DORMA TMS door management system. This provides networked security and protection for the approx. 500 doors of the new terminal, bridging distances of up to 700 metres in the process.
Comprehensive door management
The contradictory requirements of safety and security in emergency escape routes have previously been married together by the interplay of special functional elements such as exit release terminal, electromagnetic locking device (so-called "electronic keep") and door operator, with each individual door requiring an expensive and sophisticated switching control unit plus further expansion modules to meet specific requirements. So while the conflict between safety and security was eliminated at individual doors, such solutions were still a long way off from providing the comprehensive, integrated building management solution required and desired by all involved.
In order to resolve this dilemma, DORMA embarked on the development of a network-capable door management system (its TMS solution) with which the safety and security of individual doors or door groups, including the protection and monitoring of all major doors, could be organised to meet the needs of expansive building complexes such as airport terminals.
TMS only requires four cable cores, of which two are for power supply and two for data transfer – yet it still allows integration in common building system buses such as LON.
TMS is thus able to integrate, within a universal concept and with the same degree of ease, all the door functions and components required in such applications - including anti-tamper protection, emergency door release, authorised unlocking via access control systems of various designs, automatic door operators and motor locks.
Central management
While previously the electronic components of a door management system needed to be arranged locally, i.e. close to the individual doors that they served, now for the first time a central door management system has been implemented in Terminal 2 which groups all the control modules of all the doors at a single location, thus offering optimum conditions for installation and management.
Smart, future-aligned software
The monitoring and control of the doors is performed by a standard, readily programmable module. As a result, TMS offers previously unachievable flexibility in the equipment configuration and functions of individual doors – without the need for replacing or modifying the hardware in the event of functional changes or additions. With TMS, the necessary adaptation is implemented using the software alone.
This means maximum investment return, efficient and reliable reconciliation of safety and security while satisfying the principal priorities, plus maximum ease of use with no time-consuming system manipulation.
At the same time, integration within the building management system (for example via an OPC interface) enables
the combination of various access rights within groups of the same authorisation level,
centralised functional and status control,
and rapid detection of conflict and hazard situations with correspondingly fast, effective intervention in emergency situations.
Signal transmission - fibre optics and copper cabling combined for the first time
The size of the new Terminal 2 meant that it was necessary to integrate around 500 doors using the DORMA TMS system and to network these via an LON bus. In the solution selected, between 50 and 100 doors are networked within a star configuration involving seven sub-centres.
Owing to the high volume of data generated and the large distances involved, the LON bus has been created using optical fibre waveguides instead of the usual copper cabling.
DORMA has thus implemented in Munich the first genuine fibre optic router capable of switching from optical waveguides to copper conductors as the transmission media.
The sub-centres are connected to the host computer on which the DORMA TMS door management software is installed. This means that the doors can be monitored, parameterised and controlled not only from this host computer but also from the various nodal PCs.
The OPC server likewise installed on the host computer also provides an interface to the higher-level BOSCH Rubin security management system.
Flexible, user-friendly programming
In order to network individual doors within a security area, each door requires an LON module and each network needs an LON gateway. With the TMS software, the door components used can be parameterised under password protection with each operation and event being tracked and monitored at the PC.
The system can be expanded in line with demand and its functions can be modified with the utmost ease. This intelligent concept even allows remote diagnostics and tele-modification of the system in the event of faults - using Internet access combined with a specific intervention approval issued by the local user. A history function ensures that all events affecting and relating to the doors are recorded and retraceable to give a fully-fledged audit trail.
The high flexibility of the system not only enables it to be retrofitted and expanded but also allows the inclusion of new closures such as fire doors.
The system operates on the fail-safe principle so that even locked fire doors are released in the event of the power failure that often accompanies the outbreak of fire. Feedback signals triggered by positively driven contacts relating to the various operating conditions provide real-time, continuous information of the current status of the door. An anti-tamper (anti-sabotage) circuit monitors the equipment housings and wiring so that tamper attempts are also immediately detected.
Parameterisation and functional analysis at the PC
Using the sophisticated TMS software, the required functions relating to the selected access area can be specified and monitored on a door-by-door basis. In the event of an alarm, illuminated fault indicators provide precise information as to cause and current situation.
With TMS, planners and specifiers have at their disposal a comprehensive door management system that keeps all options open in terms of individual door equipment and subsequent modifications, while offering maximum flexibility in relation to the person- and group-related access authorisation modalities. Integration within bus systems not only allows implementation of fully comprehensive building safety and security management concepts but also facilitates real-time situation analyses and the instigation of effective measures in the event of alarm or emergency situations. In the case of tamper attempts, for example, the precise location is indicated on the control system monitor with the type and scope of the activity involved also being clearly defined.
With a capacity of more than 1000 doors per integrated system, DORMA TMS also offers the technical capabilities for providing tailored safety and security in even larger, more complex buildings.
DORMA technology for safe and secure convenience
Aside from the DORMA TMS door management system, Terminal 2 at Munich Airport is also the site of numerous other DORMA products serving a wide range of applications.
For example, there are thirty-two DORMA ED 200 swing door operators for securing access to the passenger bridges integrated in the TMS system. Twelve DORMA ST-Twin CS automatic sliding door operators ensure the easy flow of passengers to and from the North and South bus terminuses.
Convenience, security and safety have been reconciled by four FST/ES emergency escape telescopic sliding doors, twelve DORMA ST-G/ES sliding door systems at the North and South "airlock“ entrances and six further emergency escape sliding door systems of the type DORMA FST-R/ES in the external façade. Two DORMA FST/Iso double-glazed folding door systems and five DORMA FST/CS emergency escape sliding door sets in the special security area complete the range of automatic door systems installed at the airport terminal.
With over one hundred TS 93 GSR cam-action overhead door closers on the external doors and a further fifteen BTS 80 floor springs at the North bus terminus, DORMA’s Door Hardware division is also well represented at Munich Airport.
Finally, the company’s Glass division – DORMA-Glas – supplied 2,500 flush-mounted Manet single-point fixings for the exterior façade around the North bus terminus, and for installation of the opaque glass walls of WC facilities within the new airport terminal. It also provided a further sixty-two glass doors in combination with wall panels in the passport checking area plus seventy-two toughened all-glass doors with special framing.

With its TMS door management system, DORMA has made a significant contribution to both safety and security at Munich airport. DORMA TMS monitors and controls the functions of around 500 emergency escape doors and controlled access points such as this all-glass swing door. The access control components and emergency exit terminal are integrated in the pylon-like stainless steel column on the right.

All 500 doors are electronically networked and centrally monitored and controlled. The photo shows a view of one of the photoelectric cells with signal conversion from the fibre optic waveguides used for the longer distances to conventional copper wires (on the right) leading to the control modules of the individual doors.

It is particularly important to protect the apron area from unauthorised access. This is ensured, for example, by this 'airlock' zone created by a system of glass partitions and doors for isolating arrival passengers and departing passengers. Needless to say, the airlock door leading to the apron is kept fully secure by the TMS system.

The emergency exit pushbutton and key switch for opening the glass door leading to the apron are recessed in the stainless steel column ('pylon') as so-called 'concealed' elements to give an attractive flush-mounted effect.
