Bosch Security Systems | 2007-11 | 9922 141 70691 enDCN Wireless | Installation and User Instructions | System Design and Planning en | 121 Wireless network design1.1 IntroductionThe DCN Wireless has three parts: the wireless network, the DCN and the optical network. This chapter tells how to design the wireless network.1.2 LimitsLimit 1: Control capacityThe maximum number of devices in the wireless network that the central control unit can control is 150.Limit 2: Coverage areaFor 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.Limit 3: FrequencyThe wireless network must operate in a different frequency band than adjacent wireless (computer) networks (refer to section 1.3).Limit 4: Language Distribution enabled or disabledIf all wireless discussion units have software version 2.35 or higher, language distribution in the wireless network can either be enabled or disabled. This system setting will affect all units.For information on how to enable or disable language distribution in the wireless network, refer to section 10.6.11.Wireless discussion units that have software version 2.35 or higher have improved signaling and behavior with respect to subscription and connection, which is more in line with the wired DCN units (refer to section 14.6). The difference in signaling can be used to detect the software version of the unit. This can be 2.35, or a higher or lower version.If the wireless discussion unit has an integrated channel selector, the software version is shown on the channel selector display when:• the unit is switched on but is not subscribed to a wireless network (refer to section 14.6 for information on subscription).• the unit is in programming mode (refer to section 14.3.1).For information on how to enable or disable language distribution in the wireless network, refer to section 10.6.11.Limit 5: Number of Language Distribution ChannelsThe wireless network has a maximum of 10 language distribution channels, excluding the channel for the floor. The total number of language distribution channels in the system, is set via the interpreter desk (refer to section 33.6.6.4 in the DCN Next Generation Installation & User Instructions). If there are more than 10 Language Distribution Channels, only the first 10 channels will be available for the wireless network. All higher channels will only be available for the (wired) DCN network and/or the infrared Integrus network.NoteYou can change the power value of the wireless access point (refer to section 11.6.4).NoteWireless discussion units that have a software version lower than 2.35 will only work when language distribution is disabled.

Bosch Security Systems | 2007-11 | 9922 141 70691 enDCN Wireless | Installation and User Instructions | System Design and Planning en | 173.5.3 Power supplyThe CCU supplies power for:• the optical network, and • the units connected via the DCN cables.Refer to figure 3.1.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).3.5.4 Overload indicationEach optical network socket of the central control unit 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 supplied. The sockets are deactivated and the devices connected to the central control unit do not operate. The socket checks every 8 seconds for power overloads.3.6 Cabling3.6.1 IntroductionMany devices in the optical network have two optical network sockets that are interchangeable. You can use the two optical network sockets to make a redundant ring.3.6.2 DefinitionsThe optical network uses two types of cable:•POFPlastic Optical Fiber.•GOFGlass Optical Fiber.figure 3.1: Optical network power supplyOK FaultFaultRS 232Network12Audio In 1 Audio Out 1 Audio In 2 Audio Out 2MainsPort 2115:100-120V 50-60Hz T2.5A 250V230:220-240V 50-60Hz T2A H 250VRS 232 Port 1Trunk12230P<65WDCN-WCCUDCN-WCCUDCN-WCCUP<65WP<130WOK FaultFaultRS 232Network12Audio In 1 Audio Out 1 Audio In 2 Audio Out 2MainsPort 2115:100-120V 50-60Hz T2.5A 250V230:220-240V 50-60Hz T2A H 250VRS 232 Port 1Trunk12230OK FaultFaultRS 232Network12Audio In 1 Audio Out 1 Audio In 2 Audio Out 2MainsPort 2115:100-120V 50-60Hz T2.5A 250V230:220-240V 50-60Hz T2A H 250VRS 232 Port 1Trunk12230NoteIf only one of the optical network sockets has a power overload, the two overload LEDs come on.
Bosch Security Systems | 2007-11 | 9922 141 70691 enDCN Wireless | Installation and User Instructions | System Design and Planning en | 183.6.3 Optical fiber lengthBecause 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.3.6.4 Cable couplersYou 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.3.6.5 Maximum cable lengthThe maximum cable length (LBB4416 and GOF) of the optical network is dependent on:• The number of nodes• The number of LBB4414/10 Fiber InterfacesDo 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.NoteIf 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.figure 3.2: Cable correction graph9505010152025Nodes30 35 40 45 50 55 60 631050115 012501350145015501650175 01850195020502150Max. cable length (m)

Bosch Security Systems | 2007-11 | 9922 141 70691 enDCN Wireless | Installation and User Instructions | System Design and Planning en | 203.7.2 Basic optical networkRefer to figure 3.5 for an example of a basic optical network.3.7.3 Extended optical networkRefer to figure 3.6 for an example of an extended optical network.3.7.4 Redundant cablesThe 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).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 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.figure 3.5: Basic optical networkfigure 3.6: Extended optical networkDCN-WCCUDCN-WAPDCN-WCCUDCN-WAPLBB4404/00INT-TXPRS-4DEX4figure 3.7: Redundant optical networkDCN-WCCUDCN-WAPLBB4404/00INT-TXPRS-4DEX4
