Physical bridges are cable connections between 4100-series network nodes. They are the means by which each node in a system communicates with the other, and with the master controller. In most cases, the cable that makes up the physical bridge connects to two physical bridge cards one card per network node. The physical bridge card is basically a 4100 network interface card with three communication ports: the usual left and right network ports, plus a bridging port. The bridging port (combined with the modem media module) communicates with the remote network node’s bridge card over dedicated, leased telephone lines using a special Simplex-developed communications protocol that enables full-duplex communication between physical bridge cards. In a typical configuration, one physical bridge card represents all the nodes in the main loop and sends information over the bridge to the remote physical bridge card and network. In order for the remote physical bridge card to accept information intended for another node in its remote loop, the physical bridge card becomes a proxy: it assumes the identity of that specified node. The information is finally sent from the remote physical bridge card to the specified node.

Networking with Physical Bridges

Overview

9

Networked systems support two prevalent architectures (or wiring configurations): hub (or ring), or star. A networked system can also use a combination of the two.

The hub configuration consists of a main loop with nodes connected in a radial manner. The star configuration consists of several nodes connected directly to one common node. Physical bridge cards are used for the star configuration. Physical bridges reduce the amount of wire that would otherwise be needed to connect all nodes in a loop, and therefore cut down on system response time. A combination of the two styles is illustrated in Figure 1. FigureTag FD9-184-01

Network loops can be joined via physical bridge cards. There may be no more than two Style 7 network loops (two hub configurations) connected in tandem. For every two loops that are interconnected (using one physical bridge), there can be a maximum of three physical bridges used in a star configuration. See Figure 2. FigureTag FD9-184-02

The DIP switch and jumper settings for the physical bridge card and the modem media module vary, depending on whether Style 4 or Style 7 wiring is used.

565-649/566-794 Physical Bridge Card: SW2-1 - Operation Disable ON = Normal Operation OFF = Disables bridge, forcing bridge to act as a local repeater. (This function

allows the technician to validate topology information on the local loop.)

SW2-2 and SW2-3 - Token-Holding Time These switches indicate how many messages a bridge can send during one token time. A bridge should get more turns if it represents more nodes. Possible values are: ON, ON = 1 time unit (2 remote nodes or less) ON, OFF = 4 time units (3 to 5 remote nodes) OFF, ON = 8 time units (6 to 12 remote nodes) OFF, OFF = 16 time units (more than 12 remote nodes)

Note: These switches must be set the same way on both sides of the bridge.

SW2-4 and 2-5 - Reserved

Note: Make certain that these switches are in the ON position.

SW2-6 - Style Selection This switch indicates whether the remote bridge connection is Style 4 or Style 7. Possible values are: ON = Style 4 OFF = Style 7

SW2-8 - Send / Receive Select This switch indicates whether the bridge is to be an originator (sender) or an answerer (receiver). Possible values are: ON = Originator (Sender) OFF = Answerer (Receiver)

Configure the main network loop bridge node as the Originator and all of the remote bridge nodes as Answerers. (See Figures 1 and 2.)

This section describes mounting 4100/4120-6023 and –6024 into 2975-91xx Back Boxes.

Use the following guidelines and instruction when installing into a master controller bay.

Style 4 installation only: The Class B motherboard (575-275) must be installed to the left of the relay cards, and to the right of any motherboards using NICs. This allows for earth ground detection via the physical bridge.

Style 7 installation only: Two motherboards must be installed.

a. The physical bridge motherboard (565-275) must be installed to the left of the relay cards, but always right of the 4100 network interface card(s). This allows for earth ground detection via the physical bridge’s left port.

b. The modem media adapter motherboard (the second 565-275 in the shipping group) must be installed to the right of the physical bridge motherboard.

Relay cards must be installed in the slots immediately to the left of the power supply. This is necessary to allow for the proper routing of non-power limited wiring (120 VAC wiring connected to the relay card).

The Class B motherboard (575-275) must be installed to the left of the relay cards, and to the right of any motherboards using NICs. This allows for earth ground detection via the physical bridge.

If the 575-274 Master Motherboard is used, it must be installed in the leftmost position of this bay. If the 575-274 Master Motherboard is not used, the CPU motherboard must be installed in the leftmost position of the bay.

The power supply must be installed in the rightmost position of the bay.

Review the following guidelines before mounting the motherboard into a 2975-91xx Expansion Bay.

Style 4 installation only: The Class B motherboard (575-275) must be installed to the left of the relay cards, and to the right of any motherboards using NICs. This allows for earth ground detection via the physical bridge.

Style 7 installation only: Two motherboards must be installed.

a. The physical bridge motherboard (565-275) must be installed to the left of the relay cards.

b. The modem media adapter motherboard (the second 565-275 in the shipping group) must be installed to the right of the physical bridge motherboard.

If a power supply is installed in the bay, it must be installed on the far right of the bay and any relay modules must be installed in the slots immediately to its left.

Relay cards must be installed in the rightmost possible slots. This is necessary to allow for the proper routing of non-power limited wiring (typically 120 VAC wiring), which could be connected to a relay module.

If a 4100/4120-0155 SDACT or a 4100/4120-0153 CCDACT is installed in the bay, it must be installed in the far left or far right slot. Neither of these modules contains the J1 or P1 connectors, which are used to distribute power and communications to adjacent modules.



Installing into a 2975-91xx Expansion Bay

22

Install the motherboard as described below.

Use the following directions and Figure 10 to install a motherboard into an expansion bay.

1. Orient the motherboard with the connector labeled J1 on the right and the header labeled P1 on the left.

2. Match the connector on the previously installed motherboard with the pins on the motherboard you are installing. Slide the motherboard to the left until the pins are completely inserted in the connector of the previously installed motherboard. If you are installing the leftmost board, the pins will remain unconnected.

3. Secure the motherboard to the chassis with four torx screws.

When installing 2 x 11 ½-inch motherboards in a 4100U/4100ES expansion bay, adhere to the following guidelines: Each expansion bay assembly includes a chassis, two end supports, one LED/switch

frame, and a power distribution interface (PDI) board.

An expansion bay holds up to eight 4” x 5” modules. A double-size module, such as the expansion power supply (XPS), takes up two blocks of space as shown below.

Up to eight 2” x 11 ½” motherboards can be installed in an expansion bay if no 4” x 5” modules are installed in the bay, and if the pins on the left connector (usually P1) on the leftmost motherboard are removed. Motherboards are mounted on top of the PDI in expansion bays. The data and power that would normally be bussed via the PDI is instead routed across the boards via ribbon cable from one board to the next.

As shown in the figure below, motherboards can be installed alongside 4” x 5” cards, if necessary. Note motherboards must be on the left, and 4” x 5” modules must be on the right.

4” x 5” cards must be added from right to left.

Motherboards must be added from left to right.

If relay motherboards are installed, they must be the rightmost motherboards.

If you need to connect a 733-525 Harness to a motherboard, refer to Figure 15 and follow these steps. Make sure to route the power and communication wiring on the left side of the bay. 1. Connect one end of the harness to a motherboard in an adjacent bay.

If the adjacent bay is a CPU bay with no additional motherboards, connect the harness to the P8 and P7 connectors of the CPU motherboard.

Insert the harness connector with the blue wire into the P8 connector. Note that the P8 connector has eight pins. Insert the harness connector on either the top four pins or the bottom four pins, not in the middle.

Insert the harness connector with the white wire into the P7 connector. Note that the P7 connector has eight pins. Insert the harness connector on either the top four pins or the bottom four pins, not in the middle.

If the adjacent bay is an expansion bay or a CPU bay with additional motherboards, connect the harness to the P2 and P3 connectors of the motherboard installed in the leftmost slot. (If a 4100-6052 DACT occupies the leftmost slot, connect the harness to the motherboard in the second slot from the left.) Connect the harness as follows:



2. Connect the other end of the harness to the leftmost motherboard in the next bay, as described below. Make sure to route the wiring on the left side of the bay.

In a Style 4 configuration, the physical bridge card has to be connected to the motherboard. The same goes for the Style 7 configuration, with the additional requirement of having the Style 7 module connected to its own motherboard. The Style 7 configuration also calls for ribbon cable connections between the physical bridge and media mounting adapter card. This section describes Style 4 and Style 7 daughter card installation, respectively.

The physical bridge daughter card, shown in Figure 19 below, inserts into the connector located in the center of the motherboard. The connector is keyed so that the daughter card fits only one way. Before installing the card, examine the slot in the motherboard and the fingers on the daughter card and note where the key is located. FigureTag FD9-184-06

Review the following guidelines before connecting physical bridge cards that are remote from each other.

Make sure these guidelines are accounted for before wiring: All wires must be 18 AWG, or as the local code dictates.

Conductors must test free of all grounds.

All wiring must be done using copper conductors only, unless noted otherwise.

If shielded wire is used,

- the metallic continuity of the shield must be maintained throughout the entire cable length.

- the entire length of the cable must have a resistance greater than 1 Megohm to earth ground.

Underground wiring must be free of all water.

In areas of high lightning activity, or in areas that have large power surges, the 2081-9027 Transient Suppressor should be used on monitor points.

Wires must not be run through elevator shafts.

Wires that run in plenum must be in conduit.

Splicing is permitted. All spliced connections must either be soldered (resin-core solder), crimped in metal sleeves, or encapsulated with an epoxy resin. When soldering or crimped metal sleeves are used, the junction must be insulated with a high-grade electrical tape that is as sound as the original insulating jacket. Shield continuity must be maintained throughout.

A system ground must be provided for earth detection and lightning protection devices. This connection must comply with approved earth detection per NFPA780.

Only system wiring can be run together in the same conduit.

Transient Suppressor 748-599 is required for each modem-to-telephone line connection.

Make sure these guidelines are accounted for before wiring for power-limited systems: Non-power limited field wiring (AC power, batteries, City connection) must be

installed and routed in the shaded areas shown in Figure 22.

Power-limited field wiring must be installed and routed in the non-shaded areas shown in Figure 22, with the exception of City wiring.

Excess slack should be kept to a minimum inside the back box enclosure. The wiring should be neatly dressed and bundled together using the wire ties provided with the equipment. Anchor power-limited wiring to tie points, as shown in Figure 22.

Figure 22. Power-Limited Wiring

Tie the wiring located between bays to the internal wiring troughs, if applicable.

When powering remote units or switching power through relay contacts, power for these circuits must be provided by a power-limited power supply that listed for fire-protective signaling use. An EOL relay must be used to supervise the auxiliary power circuit.

Review the following guidelines before wiring a network with modem media boards. Modem media wiring for NICs applies to non-4100U/4100ES systems only.

Phone Line Classification consists of the following: - Private leased line for analog data communications - No dialtone - Full duplex operation - No conditioning required - No signaling required - Two-wire line interface - RJ-11 modular jack

If a four-wire circuit is required, the line must include a data station termination (DST) device to provide the two-wire interface required by the 4120 network modem. The DST device should be located as close to the FACP as possible to minimize dry line signal losses.

The modem is capable of full duplex V.32bis analog data communications. The transmit signal level is 10 dbm.

Telecommunications device: Xecom Model XE1414 or XE1414C V.32bis Two-Wire Analog Modem

Modem FCC Registration Number: DWEUSA-75322-FA-E (565-279); DWEUSA-35610-M5-E (566-338)

The following distances apply to leased modem lines: Short haul twisted pair lines (dry lines): #26 AWG: 9,500 ft (2.85 km) #24 AWG: 15,000 ft (4.5 km) Long haul twisted pair lines (wet lines): Unlimited


Wiring Guidelines

Modem Guidelines

Modem Communication Distances

38

Refer to the following guidelines whenever field wiring the physical bridges.

Network nodes must be wired right to left port, regardless of the media type selected.

Style 7 protection is achieved by wiring the nodes in a loop fashion. A single fault (except an Earth fault) will cause the network to reconfigure for degraded Style 7 (Style 4) operation. A second fault (except an Earth fault) will result in the network dividing into two separate networks.

Style 4 is achieved by wiring the nodes in a linear fashion. Style 4 networks are not fault-tolerant and a single fault (except an Earth fault) will result in the network dividing into two separate networks.

Earth fault detection is performed on the left port only. When a network Earth fault occurs, the trouble is only reported on the node whose left port is connected to the span.

All 18 AWG wiring used with 4100-6056 Wired Media Cards must be twisted shielded pair. All 24 AWG (telephone cable) used with 4100-6056 must be twisted pair. When shielded cable is used, the shield must be terminated to chassis Earth on the left port only.

It is permissible to use mixed media in a network. For example, some spans may be “wired media” while others are optical fiber or telephone modem.

Each physical bridge card has a jumper for selecting between network data rates of 57.6 kbps and 9.6 kbps. All cards in the network must be set for the 9.6 kbps data rate when modem media or physical bridging is used.

Each NIC has a jumper for selecting between 8- and 9-bit network protocols. All cards in the network must be set for the 8-bit network protocol when modem media or physical bridging is used.

All network wiring except the shield is supervised.

When wiring leaves the building, 2081-9044 Overvoltage Protectors are required. One overvoltage protector is installed where wiring leaves the building; another is installed where wiring enters the next building.

The 4190-9010 Coupler (271-012) is used with the 565-261 Fiber Optic Media Board, revision “C” or higher, with the 566-376, or with the 746-109. Two 4190-9010 Bi-Directional Couplers are required per connection, one at each node. The 4190-9010 is equipped with type ST connectors. To make type ST to type ST connections, an ST to ST coupler, by others, is required. ST to ST Couplers are available from:

2. MIFL = Maximum Individual Fiber Loss. Numbers shown are for example reference only, refer to specific cable for exact specification.

3. Maximum cable length is determined by distance listed or by reaching budget value, whichever is shorter. Maximum distances listed for dual fiber cable are shorter than would be calculated. Budget using 4190-9010 Bi-Directional Coupler is the same with either size cable because the coupler input cables are 62.5/125 fiber allowing launch power to be the same.

When the physical bridge installation is completed, verify the resultant network using the Network Programmer’s Reports. In addition, do the following: Test point status changes

Test common annunciation

Interrogate the network about point and node information

Test common trouble point status reports and responses

Use Version 7.03 (or later) of the 4100 Programming Unit to make any corrections to the network CFIG chips. (Refer to publication NET-41-003 for programming information.) When the network responses are satisfactory, replace the retainer and retainer holding screws, and close and lock the panel door for each configured node.

Since the physical bridge does not communicate with the master controller, physical bridge problems must be diagnosed. This is done through a combination of system trouble annunciation messages (e.g., Node Missing, Style 7 Abnormal, etc.) and by removing the retainer panel and observing the LED indicators on the assembly. Failure of a physical bridge connection results in Node Missing troubles for the remote nodes. Style 7 abnormal troubles are annunciated on the Operator’s Interface Panel LCD for a Main Loop Break, Remote Loop Break, or Bridge Break only if the common troubles are mapped and the Annunciate Network Troubles function is programmed in the system.

The left and right port Transmit and Receive LEDs on the Style 4 version of the 4120 Network Card are used as an aid in troubleshooting. The physical bridge ports for Style 7 installations have similar LEDs that can be used as well.

The yellow trouble LED (LED 1) on the physical bridge card can be used to diagnose system failures (see “Physical Bridge LED Indications” and “Modem Media Card LED Indications”).

The physical bridge installation causes the Network Topology Diagnostic to show a complete loop where two or more networks existed before. Figure 26 shows what the network topology information might look like for a hub-configured network.

Figure 27 shows what the network topology information might look like with an interconnected loop configuration.

Figure 27. Interconnected Loop Topology

Since the network topology information is vague when a physical bridge is connected in the loop (although attendance information is still valid), a method of diagnosing network problems is provided. Place DIP Switch SW2-1 on the physical bridge card (as shown in Figure 3) in the OFF position. This disables physical bridge communications with the remote bridge card. The topology map can now be used as a network diagnostic tool for the local loop.

hub node - A node on a 4120 network loop used to house physical bridge cards.

local loop - A group of two or more network nodes connected to each other in a ring, and connected to the 4120 network loop by a physical bridge link.

main loop – The local loop that contains the node used by the system operator to monitor all 4120 network loop activity.

modem (MODulator-DEModulator) - A device that converts digital and analog signals.

modulation - The alteration of a signal’s frequency, phase, or amplitude in accordance to a data signal.

node – A single fire alarm control panel connected to the network by a physical bridge link.

physical bridge card - A module used to bridge communications between 4120 network nodes.

physical bridge link - A communication path between two physical bridge cards. A physical bridge link can be made using up to 15,000 feet of 24 AWG twisted wire pair, or a leased private line (no dial tone, analog, full duplex, telephone circuit, with a two-wire RJ-11 interface).

remote loop - A group of two or more network nodes connected in a ring and separated from the main loop by a physical bridge link.

remote node – See node.

star configuration - Branching connections to remote nodes from a hub node.

Style 4 installation - Provides one communication path between nodes. A typical Style 4 installation would form a line. If a short or open occurs in a Style 4 installation, the connection is lost and the network divides into two smaller networks (one on each side of the fault).

Style 7 installation - Provides two communication paths between nodes. If a short or open occurs in a Style 7 installation, the physical bridge link behaves like a Style 4 installation.
