Article 1 Introduction Telecommunications is more than just voice and data. Telecommunications takes in many other building systems including Climate Control for heating, ventilation, and air conditioning, Lighting Management for increasing efficiency costs, Security for access control, surveillance and intruder alert monitoring, and Audio for public address. Indeed telecommunications can carry all low voltage signal systems that control information within the intelligent Building and modern structured cabling systems, such as the KRONE PremisNET C 3 Solution, can Control, Command, Communicate, and consolidate all these individual building systems. During the life of a building, additions and changes have become more the rule than the exception. The traditional method of proprietary cabling that supports individual building systems, can no longer support the increasing demands put on to the building owners by the occupants. The KRONE PremisNET C 3 Solution addresses this problem in a positive way. The Intelligent building cable infrastructure can be future proof designed and installed to benefit everyone. Standards Planners, Developers, Consultants and Architects are not left empty handed: there are extensive and sophisticated standards existing which help in designing and implementing building cabling systems. These communications standards define the minimum structure to deliver voice and data services to the desktop in accordance with the above standards. The relatively new concept of the consolidation point can be incorporated into a horizontal cabling design where cabling density is significant or where excessive configuration management activities are required due to staff or equipment movements. This element can be compared with the final distribution point or FDP used in block cabling distribution for voice services. This approach is developing acceptance across the market but there are few vendors that offer a range of consolidation point solutions that are included within the vendor certification process. This item will be highlighted in the next section and may become a pivotal element in the overall generic cabling design for the intelligent building. The common cabling media used today are Unshielded or Shielded Twisted Pair (Copper) and Multimode and Singlemode Optical Fibre cables. Building Management Systems Centralised control systems deliver functionality and depend on user connectivity through the horizontal and backbone sub systems to one location where all equipment is centralised. These systems were developed with product specialists and technology experts in mind and were far from user friendly to the building owner or tenant. They required highly skilled operators to gain the product efficiencies and functionality specified by these manufacturers. KRONE Premis NET C 3 Solution Page 1 With the building owner and tenant demanding high speed, high capacity information processing, increased functionality from the product and increased focus on reliability and disaster recovery, we have seen the move in the early 80’s to distributed processing environments. A distributed control system spreads its active devices and intelligence throughout the facility. Cabling designers need to be aware of the differences between these systems. Today, with the move to internationally driven Open Standard (Seven-Layer Network model) by the International Standards Organisation (ISO) as represented by the Open Systems Forum (OSF), has seen the move toward interoperability onto today’s minimum network standard, 10Mbps Ethernet.

STEP-2 Determine the best location for Floor Distributors and Building Distributors and develop backbone and horizontal cabling distribution design This activity will impact the overall cost of cabling and cabling support infrastructure requiring both labour and materials. STEP-3 Determine Cable Medium requirements. The cabling medium considered as standard for voice and data applications include: • 62.5/125 multi-mode Fibre cable • 50/125 multi-mode Fibre cable • 62.5/125 Single Mode Fibre Cable • enhanced Category 5 multi pair copper cable STEP-4 Installation A KRONE endorsed/certified installer would then proceed to install the cabling requirements. Regular discussions with the Service Application Provider and site co- ordinator will ensure correct location of cables with cable pair terminations on allocated modules and connection boxes.

The KRONE PremisNET C 3 Solution uses multiple Floor Distributors strategically placed onto each floor to capture all Building Management (BMS) System Service Applications. The KRONE PremisNET C 3 Solution has adopted a tiered hierarchy structure to simplify the understanding of the cabling hierarchy. The cabling requirements for these systems will in general be divided into three tiers of cabling. We will call these: TIER 1: Management Systems Connectivity (Application Services) TIER 2: Distributed Architecture Intelligent Device Connectivity (Backbone Services) TIER 3: Sensor or End Device Connectivity (Horizontal Services) KRONE Premis NET C 3 Solution Page 5 Network Controller End Device End Device End Device KRONE Premis NET C 3 Floor Distributor Level 2 KRONE Premis NET C 3 Floor Distributor Level 1 TIER 1 TIER 2 TIER 3 Application Specific Controller Application Specific Controller Fig 1: Tier Cabling Connectivity Diagram KRONE Premis NET C 3 Solution Page 6 KRONE Premis NET C 3 Building Distributor (Master Panel) Operator Workstation Application Specific Controller TIER 1-Management Systems Connectivity Management Systems address the Facility management, Operator management and Network management modules, which are typical of the Network Controller devices seen in today’s Control System configurations. These devices shall be connected utilising multiple 4 pair Category 5 cable to wall outlets, star configured from within a centrally designated facility managed environment. Application Services: The Application Connection Point will enable connectivity of Application Specific Controller (ASC) Input/Output (I.O) relay contacts to perform added functions from these devices. TIER 2-Distributed Architecture Intelligent Device Connectivity Backbone connectivity cabling provides connectivity though KRONE’s Building/Floor Distributors to remote Application Specific Controllers located throughout the building. These intelligent controllers will be star connected (logical bus) back to the nearest KRONE Floor Distributor and terminated onto the Application Service Connection Point. All Floor Distributors will be star configured to the Building Distributor (master panel). As a design rule it is suggested that 6 by 4 pair category 5 cables be installed in the Backbone Service to each Floor Distributor to achieve a balance of meeting today’s connectivity needs with a level of future proofing for adds moves and changes of tomorrow. A maximum cabling distance for TIER 2 cabling will apply. Whilst it varies slightly between manufacturers equipment it is generally in the order of 1500m. When connected as a physical star and logical bus the real distance between devices is limited. The number of intelligent devices connected to each logical bus is also limited and dependent upon manufacturer (From 32 and up to 50). This will be clarified in the Application Service Provider’s specifications. Backbone Services: The Backbone Service will enable the TIER 2 elements to be connected to the Network Controller. The Backbone Connection Points of Floor Distributors will enable this connectivity using multiple 4 pair Category 5 cables. TIER 3 End Device Connectivity TIER 3 cabling covers the end device cabling requirements. Each end device will utilise individual 4 pair category 5 cables fed back to the nearest Floor Distributor Horizontal Connection Point. These services will be either jumpered to an Application Connection Point or a Backbone Connection Point dependent on the functions required by the specification or systems supplier. The 90 metre distance limitations as defined by ISO 11801, will apply to Horizontal services connected to each Floor Distributor. Any Input/Output functions provided by the intelligent controller would be jumpered between the Horizontal and Application connection points. KRONE Premis NET C 3 Solution Page 7 As a rule of thumb it is suggested that a floor area be divided into three or four distribution zones and with typical floor areas having an area of 2000m 2 it is suggested that these zones cover up to 650-700m 2 each. Horizontal Services: Sensors and end devices will be connected with Category 5 4pr cables wired back to the nearest Floor Distributor Horizontal connection points. It will cover all TIER 3 elements. Where necessary these cables shall include approved connection boxes for termination points of stranded conductor tails to the end devices. Cabling Medium: The cabling used for the Control Wiring is detailed as follows: • Fibre (where appropriate) • 4 pair Category five UTP • and Figure 8 or equivalent for ELV power . PremisNET C 3 Building and Floor Distributor Fig : PremisNET C 3 Building and Floor Distributor Connection Point Layout KRONE Premis NET C 3 Solution Page 8 The Building Distributor provides the interface to all TIER cabling. The Building Distributor (master panel) provides tier 2 Backbone connectivity and also interfaces to TIER 1 management services and local TIER 3 end devices. Service Floor Distributors provide TIER 3 interconnectivity to end devices and provides connectivity for TIER 2 Backbone service interface. The Building Distributor panel is physically identical to the Floor Distributor panel. It is the location and utilisation of the Distributor panel that determines its identification as a Building or Floor Distributor. There should only be one Building Distributor panel in each building, however there can be multiple Floor Distributors on each building level. KRONE Premis NET C 3 Solution Page 9 Article 3 Cabling Lighting Control Management Systems – Practical Example The KRONE PremisNET C 3 Solution uses multiple Floor Distributors strategically placed onto each floor to capture all Lighting Control Management Systems, and wires the individual control elements (sensors) up using a star structure. This KRONE PremisNET C 3 Solution has adopted a tiered hierarchy structure to simplify the cabling hierarchy. The Lighting Control connectivity diagram shown in Fig 1 incorporates 4 pr Category 5 cables in the Horizontal, Backbone and Application Service environment to satisfy the system design requirements. Horizontal Cables: The horizontal cabling element utilises one 4 pr Category 5 Unshielded Twisted Pair (UTP) cable. The end devices supported by the KRONE PremisNET C 3 Solution include such devices as internal and external light sensing transducers. Where necessary end devices can be fitted with stranded tails by the Service Application Provider and connected to approved connection boxes used for termination points. Refer section 4.1 Approved Connection Boxes. Backbone Cables: The backbone cabling will also be equipped with 4pr category 5 rated UTP cable. Connectivity to Backbone Service Connection Points shall not be direct but through a jumper connection from the Horizontal Service. Application Cables: Intelligent control devices required to deliver direct Input/ Output functions from relay contacts etc, should be wired to the Application Service Connection Point of the nearest KRONE PremisNET C 3 Floor Distributor panel, (colour coded pink for lighting control) and from here ensure internal jumpering to achieve overall configuration desired. A Power distribution board interface will most likely be required to enable various power switching functions. The cable selection for this will depend on the relay selected. Cabling Medium: The cabling used for the Lighting Control wiring is detailed below. • Fibre (where appropriate) • 4 pair Category 5 UTP • and Figure 8 or equivalent ELV power cable for lighting circuit switching.
