Introduction to the 4100 NIC
The NIC is a slave card that uses the standard 4100 serial bus to communicate with the master. The NIC connects FACPs in a network, allowing
communication between each panel via fiber, modem, or twisted shielded pair wire in a Class X wiring configuration.
The NIC is designed to be connected in a point-to-point arrangement, so one wire fault does not cause the entire system to fail. The point-to-point
arrangement provides the most secure and fault- tolerant wiring possible.
Two types of media boards can be used with the NIC.
• The Fiber-Optic Media Card can be used for electrically noisy environments or for connecting externally to other buildings.
• Non-4100U/4100ES only: the Modem Media Card is typically used when a large transmission distance is required.
The Wired Media Card is used in all other types of applications.
Up to two media boards can be plugged into each NIC. The same NIC can use a combination of two types of media boards (for example, a NIC may
have a wired media card connected to port 1 and a fiber-optic media card connected to port 2).

Installing motherboards into 2975-91xx Back Boxes (Non-4100U/4100ES)
Mount the NIC card to 2975-91xx Master Controller Bays (4100) or, for the 4100U/4100ES, mount the NIC card to 2975-94xx CPU Bays. This section
describes mounting into 4100 Master Controller Bays.
Installing into a 2975-91xx Master Controller Bay
Use the following guidelines when installing into a master controller bay.
1. If the 565-274 Master Motherboard is used, install it in the leftmost position of the bay. If the 565-274 Master Motherboard is not used, install the
CPU motherboard in the leftmost position of the bay.
2. Install the power supply in the rightmost position of the bay.
3. Install relay cards 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).
4. If used, install the Class B motherboard (565-275) to the left of the relay cards. If a physical bridge is used with the Class B motherboard, it must
be to the right of any motherboards using NICs. This allows for earth ground detection via the physical bridge.
Installing the motherboard
1. Position the motherboard.
a. 565-274 Master Motherboard: if it is not already installed, orient with the connector labeled J3 on the right and the header labeled P1 on
the left.
b. 565-275 Class B Motherboard: orient with the connector labeled J1 on the right and the header labeled P1 on the left.

Wiring
The type of wiring used depends on the type of media cards being used in the system. The only time the motherboard terminals are used is when
wired media cards are plugged into the daughter card. Otherwise, modem and fiber connections are made straight to and from the media cards.
General Guidelines
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.
Power-Limited Guidelines
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 17.
• Power-limited field wiring must be installed and routed in the non-shaded areas shown in Figure 17, 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 17.
Figure 17: Power-limited wiring
• Tie the wiring located between bays to the internal wiring troughs, if applicable.
page 17 579-182 Rev. V
4100/4120-6014, 4100-6078 NICs and 4100/4120-Series Media Modules Installation Instruction

• 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.
• Auxiliary power only: Supervision must be provided if the auxiliary power circuit is to be wired as a power-limited circuit. In order to connect a
circuit using power-limited wiring, the devices being powered must all be addressable, or a UL Listed EOL relay must be used to supervise the
circuit. Refer to the figure below for wiring directions for the EOL relay.
Figure 18: EOL relay
NIC wiring guidelines
• Network nodes must be wired right to left port, regardless of the media type selected.
• Class X 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 Class X and Class B operation. A second fault (except an Earth fault) will result in the network dividing into two separate networks.
• Class B is achieved by wiring the nodes in a linear fashion. Class B 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 NIC has a jumper for selecting between network data rates of 57.6 kbps and 9.6kbps. All cards in the network must be set for the same
rate. (When modem media or physical bridging is used, the data rate must be set for 9.6 kbps).
• Each NIC has a jumper for selecting between 8-bit and 9-bit network protocols. All cards in the network must be set for the same network
protocol. (When modem media or physical bridging is used, the protocol must be set for 8-bit).
• 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.
• Transient Suppressor 748-599 is required for each modem-to-telephone line connection.

Dual Fiber-Optic Wiring (746-109 only)
Connectors U1 (transmitter) and U2 (receiver) on the Dual Fiber-Optic Media Card are used to connect 4100-6014 and 4100-6078 NICs across parts of
a network.
The maximum distance between nodes when using fiber cable is dependent on the size of the cable. Table 4 lists the maximum cable lengths.
Note: ST connectors with long strain relief boots are to be used with the fiber optic cable.
Figure 20 shows how two network nodes are connected via fiber-optic cable.
Figure 20: Dual fiber wiring
Dual fiber-optic connection types (746-109 only)
Dual fiber-optic cable connections. The standard fiber optic that connections between the 4120 Network nodes uses two fiber optic cables: one
for transmit, and the other for receive. This connection allows for optimum communications distance.
The available communications distance is determined by the properties of the specific fiber cable used. Distances can be determined using the
information and examples shown below in Table 4.
Single Fiber-optic cable connections. For applications where a single fiber cable is available, or where use of a single cable is desired, using a model
4190-9010 Bi-Directional Coupler at each node combines the separate transmit and receive signals into a single path (refer to the requirements list).
This connection allows use of a single fiber cable, but it does reduce communications distance as indicated in the information and examples shown
below in Table 4 and Table 5.

4190-9010 coupler requirements
The 4190-9010 Coupler (271-012) is used with the 565-261 Fiber-Optic Media Board, revision “C” or higher, the 566-376, or 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:
Black Box, part # FO200
Fiber Instrument Sales, part # F1-8101
Newark Electronics, part # 95F2097
(or equivalent)
Figure 21: Coupler wiring
The available communications distance is determined by the properties of the specific fiber cable used, the overall link topology, and the
available power budget.

Notes:
1. Fiber Type: Cable specifications are for 50 or 62.5 micron core with 125 micron cladding, multi-mode graded index fiber. Wavelength = 850 nm.
2. MIFL: Maximum individual fiber loss. Numbers shown are for example reference only, refer to specific cable for exact specification.
3. Distance: The maximum distance between nodes is determined by the total loss from the transmitter to the associated receiver (fiber loss,
connector loss, splice loss and safety margin) or the maximum distance listed, whichever is smaller. Budget using 4190-9010 Bi-Directional
Coupler is the same with either size cable. The coupler input cables are 62.5/125 fiber which allows launch power to be the same.
4. Link Budget: Measure attenuation at wavelength 850nm.
5. Dual fiber optic distances are for 746-109, 565-261 and 565-376 fiber media modules. Single fiber-optic distances require use of 4190-9010 Bi-
Directional Couplers.
