1.0 The Purpose of this Description The purpose of this description is to give an overview regarding the PBS-16 Fire Alarm System with InView Graphics and MXF-100 Optical Fibre Cable Heat Detection System. This description has been the base for the project design, which has fulfilled the details required to Hai Van Pass tunnel. This document concentrates on how the sub panels are connected to the main panel and the manner in which data is transferred between the panels, optical fibre cable system and colour graphics.

2.0 General

2.1 PBS-16 PBS-16 is a fire alarm panel capable to communicate with other PBS-16 panel units. They are locally (bus



2.2.2 MXF-100 System Description Each MXF-100 control unit will provide continuous linear heat detection over a range of up to and including 2000 m of fibre optic sensor cable (carefully adjusted up to 2200 m). The solution is based on Optical Time domain Reflectometry (OTDR) and Raman Scattering. The MXF-100 control unit and associated sensor cable together form an intelligent sensor, which is fully programmable with respect to zone lengths and alarm thresholds. The variable alarm thresholds can be either Fixed Temperature or Rate of Rise or both, depending on the application. The System operates as a stand-alone unit without a local display (Display is an option) and is to be connected to the main fire alarm system by volt free contacts (relays) and address units (Input Modules), up to a maximum of 30+2. Each of the 30 relays can have both Fixed Temperature and Rate of Rise alarm set in accordance with design requirements. Two further relays are available for System Fault and Sensor Break annunciation. Multiple alarm thresholds per zone are also possible providing always that the number of alarms do not exceed 30. The Rate of Rise function can be adjusted both in terms of rate of change with time and number of iterative counts, to eliminate false alarms.

2.2.3 Loop Ended Sensor Cable System Design The Sensor Cable is designed as a looped system with both ends of the sensor cable connected to the MXF-100 control unit. In this configuration, any break in the sensor cable will cause MXF-100 control unit to automatically default to two single ended measurement channels, without loss of functionality. This is defined as break detection recovery mode. This form of design provides a high degree of integrity and will continue to provide real time information from both ends of the severed loop.

2.2.4 Field Programming, PC Display & Remote Interrogation The MXF-100 control unit is field programmed by the commissioning engineer using a PC with Windows based software. Zone lengths (in the tunnel 50 m / zone), alarm thresholds and transit cable requirements together with system calibration are all performed using the Windows software. The zone settings and alarm threshold can be changed through this facility at a future date if required. The PC may also be permanently connected to the MXF-100 control unit for display purposes. A real time temperature trace of the sensor cable can be displayed on the PC and alarm messages highlighted and acknowledged, including identification of the actual position of a sensor cable break.

2.2.5 Sensor Cable MXF-SS, part number 516.016.113 The optical fibre with the MXF-100 control units is 62.5/125 micron (core/cladding/Acrylate coating) multimode optical fibre with stainless steel sheath. The steel is drawn out to form a very long capillary tube. By using this process, the stainless steel sheath is much less likely to suffer from corrosion. Version of stainless steel sheath with a weld seam may be more prone to corrosion. The cable is designed for fire sensing applications. It offers a high degree of mechanical protection. The 316 stainless steel sheath protects the multimode sensor



fibre from mechanical and environmental damage, whilst maintaining a low thermal mass for rapid response to temperature changes.

2.2.6 MXF-100 and Sensor Cable Performance Specification MXF-100 Standard Sensor length: -2000m (max 2200m, minimum 6m) Sampling Interval: 2.5 m (hot spot/break detection 1.25m) Temperature Resolution:



2.3 PBS-16 Field Components

2.3.1 Manual Call Points Manual call points, which are installed to the loop of PBS-16, are both analogical and addressable. Mechanically they are type Break Glass. The LED on the Call Point will inform the user by lighting up when the alarm is received by the PBS-16 panel. The call points were recommended to be installed within 60m from each other, so that each 50m zone will contain at least one manual call point.

2.3.2 Detectors The Optical Fibre cables are heat detectors, which are connected to the main Fire Alarm System with MXF-100 control units. The 30 relays are monitored with address units. In case of a fire the Fire Alarm System can indicate the location and this can be seen in PBS-16 panels and on InView Graphics displays. The PBS-16 loops have analogical and addressable heat and smoke detectors e.g. in the substations.

2.3.3 Address Units Addressable Input Modules IM10 is used to connect MXF-100 control panels to the system. The unit has 10 addresses of its own and is monitored with the help of the PBS-16 loop. 2.3.4 Control Units Output Module is an addressable relay. It has an individual address and it is monitored with the help of the PBS-16 loop. The Module in use is CR6 that is activated for ventilation contro (5 Fire Blocks) and for traffic control (5 Fire Sections). M512ME is a Control Module to monitor conventional components with idle current (current consumption 10 mA/24 VDC from PBS-16). This is used e.g. in the OCC building. The unit has an address of its own and is monitored with the help of the PBS-16 loop.

2.4 Power Supplies and redundancy Power Supplies for PBS-16 and for MXF-100 are 24 VDC with maintenance free accumulators to maintain operation for 48h in case of malfunction in the 230 VAC 50Hz net. The PC equipment is to use the local UPS net. In an emergency situation in the OCC PBS-16 user panel (PS-16) will operate even if PC and colour graphics are not in operation. To improve the security there are double PC / InView Graphics systems in the OCC.



3.0 System Layout The system layout is below (drawing 20588-1000.7). The tunnel is divided to contain six PBS-16 cabinets and an additional Fire Alarm Panel in the OCC. The PBS-16 units monitor manual call points, detectors on substations and MXF-100 control units that monitor the optical cables. The remote manual call points located in North and South Toll Plaza and in North Ventilation building S/S-6 are monitored with Fast 2000 Compact Control Panels. CN-92 communication nodes collect and transfer data between PBS-16 units and further on to the OCC for InView graphics and for PBS-16.

4.0 Alarm Transmission and Communication All the PBS-16 loops and Fire Bell outputs are supervised. The MXF-100 control unit monitors the optical fibre cable. In case of a fire or a fault PBS-16 will indicate the event locally and at the same time transmit the information to all the other PBS-16 panels, as abbreviated to Fast 2000 Compact Panels and in full to InView Graphics in the OCC building. The alarm transmission and communication is transferred from each PBS-16 to the local 30 mA COM loop, which has at least a single CN-92 communication node. This is sending and receiving data from the optical cable, which is connecting all the CN-92 in the tunnel and in the OCC building. The communication is based on the PBS-16 loop scanning, on sent messages to the 30 mA COM loop as well as the reply each PBS-16 has to give.



4.1 Communication nodes CN-92 The CN-92 Communication Node is designed for transmission and conversion of data in conjunction with PBS Fire Alarm system. In this system the CN-92 is installed in the tunnel for each PBS-16/MXF-100 system to operate as an interface for the fibre optics cable, which is to carry the local data to other PBS-16/MXF-100 systems and to the OCC. Additionally there are CN-92s in the PBS-16 Cabinet in the OCC for Colour Graphics /Modbus interface and for VMB connection. STP, NTP and SS6 have each a dedicated CN-92 to carry the data to net for all the panels.

4.1.1 Optical Fibre Cable For the use of Optical Fibre Cable there are three adjustments on how much power is transferred to the cable. The longest transfer distance is achieved at full power. The theoretical maximum distance between 2 nodes is calculated by using the following formula: L (length) = (8,22 Number of joints)/Fibre loss (km) The actual length is normally shorter as factors like temperature and how the fibre cable is placed is not considered in the above formula. It is also anticipated that the loss per joint does not exceed 1 dB, although due to practical reasons, a joint may cause a loss between 0,1 dB and 2,0 dB. The type of Optical Fibre connected to CN-92 is multimode. In those cases where the distance between equipment is too long the change from multimode to single mode and vice versa is done. (Equipment called Telebyte is used, see drawings)

5.0 Enclosures and Cabinets The degree of protection of the Manual Call Points in the tunnel is IP67. All other electronics are IP20. The PBS-16/MXF-100 electronics on local sites are installed in cabinet. The degree of protection is IP51.

6.0 InView Graphics The InView has been designed to operate under Windows 2000.

6.1 General Operation The system has been designed such that on PC power up, the InView Graphics will automatically be loaded. The normal screen shown after loading is the Main Screen. This is the view when system is in quiescent state. The Overview window shows a drawing of the whole system, tunnel and auxiliary buildings. This depicts an aerial view of the site. The top of the screen indicates a zoom level 0.



After loading the database, the system will then automatically acknowledge any alarms that have occurred during this initialisation period. In general, all graphical displays operate on a hierarchical structure. Animation links indicated by a blue box on the display allows access to zoomed views. When an alarm is present, the appropriate blue box will contain a coloured icon, the colour and shape will denote the type of alarm. In case a fire alarm is present on the overview screen (Zoom Level =0), clicking on this icon will cause the display to indicate, which is the location of the alarm (e.g. Zoom Level 1). Similarly, an alarm being generated at the SubStation1 e.g. in the GIS Room will give an indication. Again clicking on this icon will cause the detector representation to be displayed (Zoom Level 1). Alarms are prioritised such that in the Fire system: Fire > Prewarning > Faults > Status > System. All available functions within the system are assigned a password level, such that when activating a specific function request, you may see a window appearing which indicates that the specific password level was not high enough to allow that function to operate. In this case, you will need to log on to the system again (via the Utilities function Main Screen) and enter a higher-level access code. In some cases, certain function control buttons have been made invisible to lower level access codes. If you access a control, which has a higher password level assigned to it than the current one, then a Pop Up -screen will inform you of this.

6.2 SCREEN DISPLAYS & CONTROLS

6.2.1 Overview Screen This screen is displayed when clicked from the main screen and displays a site overview. All alarms will be indicated on this screen in some form. Selecting an appropriate area within the graphical display screen will allow access to a different display. This usually represents a zoomed view of this area. Other areas may be zoomed until one reaches the lowest level that contains representations of detectors. There are a number of control buttons on the screen that are used to provide a number of functions. The following picture is an Overview Screen:



6.2.1.1 Acknowledge Button This command acknowledges any new alarms received. This function is available not only on the Main Screen, but also on a number of other display screens. It is used to acknowledge any new alarms that have been received. If audible alarm indication has been installed within the PC, then pressing this button will silence the alarm. Also, all unacknowledged alarms will be flashing, and pressing this button will cause them to remain on.

6.2.1.2 Main Screen Button This command button activates the Main Screen display. Next page.

6.2.2.1 Log On / Off Button This function is used to control function access levels within the InView Graphics. To change access level, activate the button. This will bring up a display. This screen allows User Names and Passwords to be entered into the system. By default the access level is operator. Other options are listed below. User Name Password Access Level None No Password 0 Operator 99 1 Engineer 123 2

6.2.2.2 Access Level 0 This level disables all functions apart from monitoring alarms. No functions are available. There is NO access to the Utility screen, so that if you have set this level previously, then you will be unable to set a higher-level access using the Utility Screen. This is so that the system can be left with untrained personnel who may try to interfere with the normal operation of the system. To return to a higher level access then use the following Keyboard Combination Control L Pressing Control L will immediately display the Log On / Log Off screen so that a different user can be entered. 6.2.2.3 Access Level 1 This level allows 95% of all functions to be accessed and is the normal start up mode used.



6.2.2.4 Access Level 2 This level allows all functions to be accessed apart from a complete database system download, which is available via one of the Textual Alarm Screen Displays.

6.2.2.5 Change Password Button This function allows the user to change any of the passwords. Currently passwords are as described above.

6.2.2.6 Copy Log Files Button This function allows the copying of all alarm log files AND any Detector information files from the Hard Disk to a floppy disk.

6.2.2.7 Reinitialise Button This function is used if the CN-92 has been powered down, and after powering up, the InView Graphics does not come on-line or there seems to be a communication problem. Use this command prior to a complete PC Power Down / Up sequence.

6.2.2.8 Interrogate PBS This function allows access to various detector/Module values.

7.0 Operational Controls

7.1 Introduction The System Architecture is based on subsystems. This means that in case of malfunction each individual subsystem can be operated locally. This is a benefit from maintenance point of view. Along the tunnel there are 6 sites with PBS-16/MXF-100. MXF-100 may be connected to the PC so that the optical fibre can be continuously monitored. PBS-16 has a user panel and each of the 6 sites in the tunnel can monitor the manual call points and possible other detectors connected to the detection loop and MXF-100. The OCC building has InView Displays for ordinary control and operation work. In case of malfunction in PCs there is still a single PBS-16 panel to control the total Fire Alarm System in the tunnel and in its surrounding.

7.2 PBS Controls (SYSTEM COMMANDS) User controls the system with the InView PC. The typical tasks are to disconnect and reconnect zones or detection points when needed. In an emergency situation the system informs the user regarding the fire and faults and at the same time shows the instructions dedicated to the alarm points. After the alarm the system is reset with the key board/mouse. ( User can activate manually several control outputs with mouse or key board. These outputs will be specified during the design work of the system. )



( A typical manual control is the Zero Air Velocity Under Emergency. The alarm System detects a fire in a specific area and proposes to stop the ventilation of that area. The system will propose, the user will confirm and the ventilation will stop. )

Silence : Silence all alarm bells in the system. Unsilence : Reactivate all alarm bells in the system (under fire alarm state, when alarm bells have been silenced) . Reset: Resets all panels in the system. Quit: Exit this screen. Isolation/Restore: Isolate and restore loops or address points. Note ! Only one system installed (named here as HVPT, SYSTEM 1).

8.0 System Controls The system itself will control automatically the specified outputs. The interfaces of outputs to other systems are voltage free relays. These automatic controls will be specified during the design of Cause&Effect of the Fire Alarm System. For System control purposes there are several relays in each PBS-16/MXF-100 cabinet depending on how RS56/IF16 unit is equipped. The connection with TCP/IP from InView systems is permitted with additional software. This allows direct access to the alarm database via TCP/IP. Note! Log files are text files.
