The Serial Interface Board

• The Serial Interface Board (SIB-NET) connects an
  AM2020 or AFP1010 to the network through an MIB.
• Each AM2020/AFP1010 requires a network node
  address and the SIB-NET permits communication
  between the AM2020/AFP1010 and other nodes on the
  network.
• The SIB-NET also provides an EIA-232 and EIA-485
  output circuits for other external devices.

The NRT-NET Board

• The NRT-NET interface card and a MIB allow the
  Network Reporting Terminal (NRT) to communicate
  with the network.
• The NRT-NET interface card plugs directly into a
  computer expansion slot located on the NRT mother
  board.
• The MIB plugs onto the NRT-NET card to complete
  the network interface.
• Each NRT requires a network node address.

The Repeaters (RPTs)

• The Repeaters (RPT) boost data signals between
  network nodes extending communication distances.
• RPT-W supports twisted pair wire
• RPT-F supports fiber optic cable
• RPT-WF supports twisted pair wire and fiber optic
  cable.

NOTI-FIRE-NET Specifications

• When designing the wiring layout of a
  NOTI-FIRE-NET system, the following distance
  limitations must be considered
• 1.The length of each individual twisted pair or
  fiber optic segment is limited. A segment is
  either point-to-point of two nodes/repeaters or
  bus connection (wire only) containing three or
  mode nodes.

NOTI-FIRE-NET Specifications

• NOTI-FIRE-NET distance limitations
• Twisted Pair circuits
• The length of cable for each segment in the
  system must be within the range specified in
  Table 1.5-1. If the distance required is greater
  than permitted, a RPT must be inserted into the
  circuit.
• Cable type should be selected to satisfy the code
  requirement specific to a particular application.
• Note This table has been expanded to include
  more wire sizes and styles since original
  preparation. See the table in the manual for more
  information.

• Fiber Optic circuits
• Cable attenuation between two nodes must not
  exceed a 10 dB limit. Distances greater than
  permitted require a repeater module inserted at
  intervals less than or equal to 10 dB.
• To determine loss, find the rated dB loss per
  foot and multiply by the distance required, and

• 2. System path length is limited and determined
  by using Table 1.5-2. The path is defined as the
  distance of travel from one end of the network to
  the other, and is influenced by the number of
  MIB, NAM and RPT devices, and medium of the
  circuit path.

Minimum Requirements

• An NRT or INA and a fire panel with initiating
  devices and notification appliances define the
  minimum system requirements for a NOTI-FIRE-NET.
• For each AM2020/AFP1010 panel configured for NFPA
  72-1993 Local Fire Alarm System a CMX module set
  at Loop 1, address 96 with Type ID EVGA is also
  required.

NFPA Style 4 Configuration

• Noti-Fire-Net is capable of communicating using
  NFPA Style 4 SLC.
• Under this style of operation, a single open,
  wire-to-wire short, wire-to-wire short and open,
  wire-to-wire short and ground, or open and ground
  results in fragmentation of the network.
• A single ground does not affect communication,
  but is detected.
• Each fragment of the network reconfigures to
  permit communications among nodes within the
  fragment.
• Page 12

26
NFPA Style 4 Configuration
NFPA Style 4 SLC Without Regeneration (Bus
Connection)
NOTE A wire-to-wire short
here results in loss of commu- nication between
all four nodes/repeaters on this bus connection
as well as fragmentation of the net- work. Bus
connections should be no longer than 100 within
conduit or the same enclosure.
27
NFPA Style 4 Configuration

• In an NFPA Style 4 fiber-optic system, a single
  break will result in loss of communication
  between network nodes within the fragment of the
  network that can only receive signals from the
  other fragment.
• Page 13

28
NFPA Style 7 Configuration

• Noti-Fire-Net is capable of communicating using
  NFPA Style 7 SLC.
• Under this style of operation, a single open,
  wire-to-wire short, wire-to-wire short and open,
  wire-to-wire short and ground, or open and ground
  will not result in fragmentation of the network.
• A single ground does not affect communication,
  but is detected.
• Style 7 operation may be achieved using fiber
  optic cable or mixed media (wire and fiber)

Configuration Definitions

• Point-to-Point wiring configuration is defined as
  a twisted-pair segment with only two nodes/
  repeaters attached to it. Terminating resistors
  are required at each end of every segment, and
  are built into each MIB, NAM-232, and RPT.
• Page 14

31
Configuration Definitions

• Characteristic Impedance in a Point-to-Point
  Configuration
• Wire segment of each connection is a transmission
  line.
• Physical construction of the cable used
  determines the characteristic impedance of that
  segment.
• To minimize unwanted data reflections, never mix
  more than one brand name, gauge or type of wire
  within a segment.

Bus Configuration

• A bus wiring configuration is defined as a
  twisted pair network with more than two nodes.
  Terminating resistors are only needed on the
  first and last node of the bus pair, all other
  resistor must be removed.
• Page 16

34
Bus Configuration

• In a bus configuration, more than one node
  /repeater shares the same circuit.
• A fault anywhere along the bus will affect the
  rest of the nodes/ repeaters on the bus.
• Because of their inherent weakness, bus
  configurations are best employed for wiring
  between nodes/repeaters local to each other
  (within the same cabinet or room).
• Page 16

35
Bus Configuration

• Wiring Distances Between Nodes on a Bus
• In a bus configuration, data is shared between
  all ports on the twisted pair, thereby reducing
  the allowable transmission distance to a maximum
  of 100 ft.
• Page 16

36
Bus Configuration

• Characteristic Impedance in a Bus Configuration
• The wire segment for each bus connection is a
  transmission line.
• The physical construction of the twisted-pair
  cable used for a segment determines the
  characteristic impedance of that segment.
• To minimize unwanted data reflections, never mix
  more than one brand name, gauge, or type of wire
  within a bus segment.
• Always make bus connections at the module
  terminals provided.
• Do not make branch connections at other points.
• Page 16

37
Combination Configuration

• A Combination configuration can be used to
  distribute the network circuit from a central
  facility, saving on wiring run lengths.
• A repeater is bus-wired to two existing nodes in
  each central facility (located in the same room)
  to support point-to-point connections in the
  remaining buildings in the system.
• Page 17

38
Terminating Point-to-Point and Bus Configurations

• Both point-to-point and bus twisted wire pair
  configurations require end-of-line termination at
  each end of the respective circuit.
• Whereas a point-to-point circuit has a
  terminating resistor at each node/repeater port,
  a bus circuit spans multiple nodes/repeaters,
  with termination only at the outer edges of the
  circuit.
• Page 18

39
Terminating Point-to-Point and Bus Configurations

• Terminating resistors are present on all MIBs,
  NAMs, and repeaters. The terminating resistor on
  the first and last nodes/repeaters of a wire
  segment must remain intact. The terminating
  resistors on all the other nodes/repeaters
  connected to the same bus segment must be cut and
  removed from each board.

Network Wiring Ground Fault Detection

• Twisted pair communications links between nodes
  can be isolated through the MIB/ NAM transformer
  coupling, so a single ground fault has no effect
  on circuit operation.
• Ground fault of the isolated link is not
  necessary unless required by LAHJ.
• Ground fault detection from a node power supply
  may be fed-through or disabled at the MIB/NAM.

Network Wiring Ground Fault Detection

• Ground fault circuit operation
• Ground fault detection may be provided by a FACP
  node which is powered by a MPS-24A or by an
  AFP-200 connected with a NAM-232.
• INA and NRT cannot provide ground fault
  detection. Switches SW1 and SW2 on the INA or NRT
  must always be off.
• Page 20

Network Wiring Ground Fault Detection

• Point-to-Point Configuration
• In point-to-point without repeaters, enable
  ground fault in only one of two nodes.
• Page 20

48
Network Wiring Ground Fault Detection

• Point-to-Point Configuration
• If an RPT-W is used, two ground fault detection
  schemes are possible. One or both nodes may
  provide detection depending on the RPT pass
  through switch (SW3) Setting.

Network Wiring Ground Fault Detection

• Bus Configuration
• In a bus configuration, as in point-to-point,
  only one node can provide ground fault detection
  along the bus.
• The primary difference is that one node can
  provide ground fault detection for multiple nodes
  along the bus.

• Bus Configuration
• 2nd node from right provides ground fault
  detection.
• All other nodes have ground fault disabled.
• Note Termination resistors removed from
  pass-through bus ports.
• Page 22

54
Network Wiring Ground Fault Detection

• Bus Configuration
• Node on the left and 2nd node from right provide
  ground fault detection, and RPT SW3 is off to
  prevent pass through.
• This creates two separate ground fault circuits.
• All other nodes have ground fault disabled.

FCC Considerations

• In order to comply with FCC regulations regarding
  radio frequency emissions, a ferrite cylinder
  (Notifier p/n 29087) must be installed on every
  twisted pair circuit connected to a MIB-W (two
  cylinders included) and MIB-WF (one cylinder
  included).
• Page 20

56
FCC Considerations

• NRT Installation
• Thread the twisted pair(s) through the ferrite
  cylinder.
• Slide the cylinder along the pair(s) toward the
  MIB on the back of the NRT so that the closest
  edge of the cylinder is no more than 3 inches
  away from the terminal connection block.
• Secure the ferrite cylinder to the wiring with
  the supplied toe wrap at each end of the
  cylinder.
• Page 23

57
FCC Considerations

• INA SIB-NET Installation
• Thread the twisted pair(s) through the ferrite
  cylinder.
• Slide the cylinder along the pairs toward the
  entrance point on the cabinet (not toward the
  MIB) so that the edge of the cylinder and the
  cabinet are separated by no more than three
  inches.
• Secure the ferrite cylinder to the wiring with
  the supplied tie wrap at each end of the
  cylinder.
• Repeat for the second MIB-W port.

Tips and Techniques

• How to recognize and fix ground loops
• Its important to realize that a ground loop is
  not the same as a surge. A ground loop is a
  consistent electrical state, causing a steady
  high voltage with high current capability. A
  voltage surge, although it may be higher and more
  powerful, is typically an induced voltage with a
  very fast rise time.

59
Noti-Fire-Net Data Pulse

• The two thresholds available are HIGH (1.4 Volts)
  and LOW (800mV). If the pulse width 2.1 at the
  HIGH(TH, 1.4V) and 2.4 at the LOW(TL, .8V), the
  threshold should be set to HIGH. The main
  criteria is to look for is a pulse width gt 1.1
  uSec at each threshold.
