This chapter tells how to design the wireless network. Limits 1.2 Limit 1: Control capacity The maximum number of devices in the wireless network that the central control unit can control is 150. Limit 2: Coverage area For a good operation of the wireless part, all wireless discussion units need to be in range of the wireless access point. The wireless access point has a typical maximum coverage area of 30 m by 30 m. To determine the exact coverage area the coverage test kit can be used. Note You can change the power value of the wireless access point (refer to section 11.6.4). Limit 3: Frequency The wireless network must operate in a different frequency band than adjacent wireless computer networks (refer to section 1.3). 802.11g specification 1.3.1 The wireless network is based on the 802.11g specification for WiFi technology. Devices that comply to the 802.11g specification operate in frequency bands between 2.4000 and 2.4835 GHz. Note Although the system operates on frequencies which are license free world wide, you must be aware of country specific limitations and follow them. 1.3.2 Wireless computer networks Wireless computer networks are also based on the 802.11g specification for WiFi technology. In the wireless computer networks, 13 overlapping channels are available (refer to figure 1.1). 1.3.3 Carriers In the wireless network of DCN Wireless, three non-overlapping wireless carriers are available (refer to figure 1.2). Interference 1.3.4 The wireless network of DCN Wireless can cause interference on wireless computer networks. You must make sure the DCN wireless carrier does not overlap the WLAN channel. 1.3.5 Example Refer to figure 1.3. In the example, the WLAN channel is 3. WLAN channel 3 overlaps DCN wireless carriers 0 and 1. Therefore, use DCN wireless carrier 2.

This chapter tells how to design the DCN. 2.2 Calculation tool The calculation tool makes the planning and design of the DCN easier. You can find the calculation tool on the CD-ROM that is supplied with your system. 2.3 Concepts Introduction 2.3.1 This section gives necessary data to understand the limitations in section 2.4. Trunk and tap-off sockets 2.3.2 The DCN uses two types of socket:
DCN trunk sockets Use the DCN trunk sockets to make a loop-through in the trunk of the DCN. DCN tap-off sockets Use the DCN tap-off sockets to make more branches in the DCN. A DCN tap-off socket always regenerates the digital DCN signal. 2.3.3 Cables Many devices used in the DCN have a 2 m cable. If necessary the extension cable (LBB4116) can extend the device cables. Limits 2.4 Make sure that these limits are not exceeded when you design the DCN:
Limit 1: Control capacity The maximum number of active devices that the central control unit can control is 95:
Max. 93x DCN-IDESK Max. 2x DCN-DDI:
1x with intercom handset 1x with ambient microphone The number of passive devices is without limit (refer to section 2.5). Limit 2: Power capacity The maximum power that one DCN socket of the central control unit can supply is 65 W. The total power that the DCN sockets of the central control unit can supply is 130 W. The maximum power that one DCN socket of the extension power supply can supply is 85 W The total power that the DCN sockets of the extension power supply can supply is 255 W. Refer to section 2.6. Limit 3: Loop-throughs The maximum number of loop-throughs in succession is 50. If there are more than 50 loop-throughs, the signal must be regenerated with a trunk splitter (LBB4114/00). Limit 4: Tap-off connections The maximum number of tap-off connections in succession between the central control unit and the last tap-off in a branch is four. If there are more than four tap-off connections in succession, the system does not operate correctly. Bosch Security Systems | 2007-02 | 9922 141 70691 en DCN Wireless | Installation and User Instructions | System Design and Planning en | 15 Limit 5: Cable lengths Refer to section 2.7:
With regenerative tap-offs, the maximum cable length is 250 m from the central control unit to the furthest device in any branch of the DCN. The maximum cable length from the central control unit to the first regenerative tap-off is 100 m. The maximum length of the cable between regenerative tap-offs is 100 m. Open-ended cables can cause an incorrect operation of the system. 2.5 Control capacity 2.5.1 Active devices Active devices are devices that can:
Receive data from the central control unit. Transmit data to the central control unit. Note Active devices must have an address (refer to section 12.2). Note The total cable length includes the 2 m long device cables. 2.5.2 Passive devices Passive devices can only receive data from the central control unit. 2.5.3 Overview The table shows the active and passive devices in the DCN. table 2.1: Active and passive devices Device DCN-DDB DCN-DDI DCN-FCS DCN-IDESK Type Passive/Active Active Passive Active 2.6 Power capacity Introduction 2.6.1 Each device uses power and most devices do not have an independent power supply. 2.6.2 Power consumption The table shows the power each device in the DCN uses. table 2.2: Power consumption Device DCN-DDB DCN-DDI DCN-FCS DCN-IDESK Watt 2.0 4.5 0.9 3.6 Bosch Security Systems | 2007-02 | 9922 141 70691 en DCN Wireless | Installation and User Instructions | System Design and Planning en | 16 2.6.3.3 DCN-EPS DCN-EPS e Trunk Tap-off In Out Out Out DCN-EPS Trunk Tap-off In Out Out Out P < 85 W P < 255 W figure 2.2: DCN power supply: DCN-EPS Note If the power is higher than shown in figure 2.2, an overload situation occurs (refer to section 2.6.4). Introduction 2.6.3 Power supplies 2.6.3.1 The devices that supply power to the DCN are the central control unit and the extension power supply
(refer to figure 2.1 and figure 2.2). The power that the central control unit supplies includes the power that the optical network uses. 2.6.3.2 DCN-WCCU DCN-WCCU RS 232 Port 1 RS 232 Port 2 Audio In 1 Audio Out 1 Audio In 2 Audio Out 2 Network 1 2 Trunk 1 2 Fault OK Fault Mains 230 115: 100-120V 230: 220-240V 50-60Hz 50-60Hz T2.5A 250V T2A H 250V P < 65 W DCN-WCCU RS 232 Port 1 RS 232 Port 2 Audio In 1 Audio Out 1 Audio In 2 Audio Out 2 Network 1 2 Trunk 1 2 Fault OK Fault Mains 230 115: 100-120V 230: 220-240V 50-60Hz 50-60Hz T2.5A 250V T2A H 250V P < 130 W DCN-WCCU RS 232 Port 1 RS 232 Port 2 Audio In 1 Audio Out 1 Audio In 2 Audio Out 2 Network 1 2 Trunk 1 2 Fault OK Fault Mains 230 115: 100-120V 230: 220-240V 50-60Hz 50-60Hz T2.5A 250V T2A H 250V P < 130 W figure 2.1: DCN power supply: DCN-WCCU Note If the power is higher than shown in figure 2.1, an overload situation occurs (refer to section 2.6.4). Bosch Security Systems | 2007-02 | 9922 141 70691 en DCN Wireless | Installation and User Instructions | System Design and Planning en | 17 2.6.4 Overload indication Each DCN socket of the central control unit and extension power supply has a red LED that comes on to show that there is a power overload. An overload occurs when:
The necessary power for the devices is greater than that is supplied. A short-circuit occurs. When an overload occurs, the sockets are deactivated and the connected devices do not operate. The socket checks every 8 seconds (DCN-WCCU) or 30 seconds
(DCN-EPS) for power overloads. 2.6.5 Extension cables Extension cables (LBB4116) have a direct effect on the available power. The longer an extension cable, the less power is available to drive the connected devices. You must chose the length of the extension cables carefully
(refer to section 2.7.5). 2.7 Cable lengths 2.7.1 Maximum length The cable length between the central control unit and the furthest device from the central control unit must not be more than 250 m. The cable length includes the device cable and extension cables. To first regenerative tap-off 2.7.2 The total cable length between the central control unit and the first regenerative tap-off socket must not be more than 100 m. This includes the device cables and extension cables. 2.7.3 Between regenerative tap-offs The total cable length between two regenerative tap-off sockets must not be more than 100 m. This includes the device cables and extension cables. 2.7.4 Open-ended DCN cables Open-ended DCN cables are DCN cables of which the socket is not connected to a device in the DCN. Open-ended cables can cause an incorrect operation of the system. You can close the extension cable with a termination plug (refer to the DCN Next Generation Installation and User Instructions). When the open-ended cable is connected to a termination plug, the system operates correctly. Introduction 2.7.5 Power correction 2.7.5.1 The necessary power from a DCN socket of the central control unit and the extension power supply is affected by:
The type and number of connected devices. The lengths of the connected extension cables. The power correction graph (refer to figure 2.3) corrects the power level to compensate for the extension cables. Calculation 2.7.5.2 To find the correction for each DCN socket of the central control unit and the extension power supply with the graph, you must first calculate:
The total power consumption of the devices that are connected to the socket. Refer to section 2.7.5.3. The length of the longest extension cable sequence. Refer to section 2.7.5.4. Bosch Security Systems | 2007-02 | 9922 141 70691 en DCN Wireless | Installation and User Instructions | System Design and Planning en | 18 Total power consumption 2.7.5.3 Do as follows:
1 Find the power consumption of each device from the consumption table (refer to table 2.2). 2 Add together the power used by all the devices. The result is the total power consumption of the devices that are connected to the socket. 2.7.5.4 Length of the longest extension cable sequence Do as follows:
1 Add together the lengths of all extension cables in the longest sequence. Graph 2.7.5.5 The power correction graph (refer to figure 2.3) corrects the power level to compensate for the extension cables. Do as follows:
1 Find the total power consumption (refer to section 2.7.5.3) on the vertical axis (Y) of the power correction graph. For example, 40 W. 2 Find the length of the longest extension cable sequence (refer to section 2.7.5.4) on the horizontal axis (X) of the power correction graph. For example, 60 m. 3 The intersection of both values gives the necessary power from the socket. For example, 53 W. For example, an extension cable of 20 m is connected directly to a DCN socket of the central control unit. To the extension cable, a trunk splitter is connected. To each tap-off socket of the trunk splitter, an extension cable is connected. One extension cable has a length of 10 m, the other extension cable has a length of 40 m. The length of the longest extension cable sequence is, in this example: 20 + 40 = 60 m. 85 80 75 70 65 60 55 50 45 40 35 30 25 20 15 10 5 0

This chapter tells how to design the optical network. 3.2 Calculation tool The calculation tool makes the planning and design of the optical network easier. You can find the calculation tool on the CD-ROM that is supplied with your system. Limits 3.3 Make sure that these limits are not exceeded when you make the optical network:
Limit 1: Control capacity The maximum number of nodes in the optical network is 63 (refer to section 3.4). Limit 2: Number of devices The maximum number of devices that you can connect to the optical network of the central control unit is 16. The maximum number of DCN-WAP Wireless Access Points in the optical network is 1. Limit 3: Power capacity The maximum power that the optical network sockets of the central control unit can supply is 65 W (refer to section 3.5). Limit 4: Cables Refer to section 3.6:
The maximum length of a POF cable is 50 m. The maximum cable length (POF and GOF) of the optical network is dependent on the number of nodes in the optical network. The minimum bend radius of a 90 degree bend in a POF cable is 110 mm. The minimum coiling radius of a POF cable is 110 mm. 3.4 Control capacity Each device in the optical network has a number of nodes (refer to table 3.1). The maximum number of nodes in the optical network is 63. table 3.1: Nodes Device DCN-CCU DCN-WAP LBB4402/00 LBB4404/00 LBB4410/00 LBB4414/10 INT-TX04 INT-TX08 INT-TX16 INT-TX32 PRS-4DEX4 Nodes 2 1 1 1 1 0 1 2 4 8 1 3.5 Power capacity Introduction 3.5.1 Each device uses power and most devices do not have an independent power supply. 3.5.2 Power consumption The table shows the power each device in the optical network uses. table 3.2: Power consumption Device DCN-WAP LBB4402/00 LBB4404/00 LBB4410/00 LBB4414/10 PRS-4DEX4 Watt 4 7.6 10.5 3.9 4.6 6.0 Note The Integrus transmitters do not use power from the system.

You can use the two optical network sockets to make a redundant ring. Note The two optical network connectors are the same. 3.6.2 Definitions The optical network uses two types of cable:
POF Plastic Optical Fiber. GOF Glass Optical Fiber. figure 3.1: Optical network power supply If more power is necessary, you must install external power supplies in the optical network. The devices below can connect to external power supplies:
LBB4410/00 Network Splitter (refer to the DCN Next Generation Installation and User Instructions). LBB4414/10 Fiber Interface (refer to the DCN Next Generation Installation and User Instruction). Bosch Security Systems | 2007-02 | 9922 141 70691 en DCN Wireless | Installation and User Instructions | System Design and Planning en | 24 3.6.3 Optical fiber length Because of optical attenuation, the maximum length of optical network cables (LBB4416) is 50 m. You can use GOF and fiber interfaces to increase the distance between devices to a maximum of 1500 m. 3.6.5 Maximum cable length The maximum cable length (LBB4416 and GOF) of the optical network is dependent on:
The number of nodes The number of LBB4414/10 Fiber Interfaces Do as follows:
1 Find the number of nodes of each device from the node value table (refer to table 3.1). Add together the nodes of all devices. 2 With the value of step 1, use the graph (refer to figure 3.2) to find the maximum cable length without LBB4414/10 Fiber Interfaces. 3 Count the number of LBB4414/10 Fiber Interfaces. Each fiber interface decreases the maximum cable length from step 2 with 18 m. Note If the distance between two devices is less than 100 m, use a network splitter between devices to remove the use of fiber interfaces. Use only the trunk sockets of the network splitter in this case. 3.6.4 Cable couplers You can use the LBB4419/00 Cable Couplers to connect optical network cables to each other. A cable coupler causes optical attenuation. Each cable coupler decreases the maximum distance between two devices in the optical network (normally 50 meters) with 20 meters. 2150 2050 1950 1850 1750 1650 1550 1450 1350 1250 1150 1050 950

This chapter shows examples of the possible layouts of optical networks. Bosch Security Systems | 2007-02 | 9922 141 70691 en DCN Wireless | Installation and User Instructions | System Design and Planning en | 26 3.7.4 Redundant cables The example of the extended optical network (refer to figure 3.6) has no redundant cable. If the cable between the central control unit (DCN-WCCU) and the wireless access point (DCN-WAP) breaks, the central control unit cannot transmit data to the wireless access point. A solution for this problem is to use redundant cable (refer to figure 3.7 for an example). DCN-WCCU LBB4404/00 PRS-4DEX4 DCN-WAP INT-TX figure 3.7: Redundant optical network The example of the system without redundant cable
(refer to figure 3.6) has no connection between the cobranet interface (LBB4404/00) and the central control unit (DCN-WCCU). The example of the system with redundant cable has a connection between the Cobranet Interface and the central control unit. This connection makes a ring. If a cable breaks, the optical network continues to operate. The maximum total power of all devices in the redundant optical network is 65 W. If the optical network is defective near the central control unit, the other socket can supply power to all of the optical network. 3.7.2 Basic optical network Refer to figure 3.5 for an example of a basic optical network.

Objects can fall through the airflow holes. A blockage of the airflow holes can cause a risk of fire. Caution Do not put the devices near or above a radiator, heat grill or in direct sunlight. Caution Do not cause vibration of the devices. Make sure that the area is clean. Make sure that the air is sufficiently cool. Make sure that there is sufficient lighting. 8.2 Cables Use different cable ducts for the extension and mains cables. Identify each cable with a label and divide trunks to manageable geographic locations. In public areas where people can touch or move above the connectors and cables, use metal protection covers. Refer to the applicable protection specification of the protection covers. Temperature 8.3 When devices are in a 19-inch rack, make sure there is rack space between the devices to let sufficient air flow. Forced airflow may be necessary to keep the temperature of the devices below the maximum temperature (refer to section 9.2). This extends the lifetime of the devices. Ventilation 8.4 Keep a good airflow. Airflow holes are in the front, right and left sides of all 19-inch devices (for example, the central control unit and the audio expander). Put the devices on a hard and level surface. Put the central control unit at minimum distance of 0.10 m from walls to let sufficient air flow. 8.5 Cleaning Caution Do not use alcohol, ammonia or petroleum solvents or abrasive cleaners to clean the devices. 1 Disconnect the mains power supply from the devices, if you want to clean the devices. 2 Use a soft cloth that is not fully moist with a weak soap and water solution. 3 Let the device fully dry before you operate the device again. 8.6 Storage Note If the central control unit is stopped or disconnected from the mains power supply for more than 100 days, the values of all system parameter are erased. This includes all the values of the parameters of the interpreter desks and the wireless access point. This does not include the subscription list. 1 Disconnect the mains power supply from the devices, if you do not use the devices for a long time. 2 Keep the devices in a clean and dry area with a sufficient airflow.
