Noti-Fire-NetTM
Equipment that connects to NOTI-FIRE-NET and communicates with other equipment using the network may be referred to as a network node. NOTI-FIRE-NET supports up to 103 nodes with a total capacity of 201,960 points. A node may be:AM2020 Fire Alarm Control PanelAFP1010 Fire Alarm Control PanelNRT Network Reporting TerminalAFP-200 with NAM-232 ModuleINA Intelligent Network Annunciator

Media Interface Board
The Media Interface Board (MIB) provides the physical interface to the following medium which connects node together forming a network:MIB-W - Two twisted pair wire portsMIB-F - Two fiber optic cable portsMIB-WF - One twisted pair port and one fiber
optic cable portPage 4

Network Adapter Module
NAM-232 Provides a physical interface from the AFP-200 or AM2020/AFP1010 Analog Fire Panel through the EIA-232 data port to the NetworkNAM-232W - Two twisted pair wire portsNAM-232F - Two fiber optic cable ports

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.Page 5

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 distance limitations :Twisted Pair circuitsThe 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.

Note: In the event of a power failure at a wire node, the data is not regeneratedlocally, it is merely fed through to the next node. Therefore, the total length ofwire is the sum of both lengths of wire between operating nodes. If the total lengthexceeds the maximum allowable length for a given threshold, the network maylose communication. Separately powered repeaters may be employed at each nodein a point-to-point series connection to ensure data regeneration.

NOTI-FIRE-NET Specifications
NOTI-FIRE-NET distance limitations :Fiber Optic circuitsCable 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 add the dB loss for each connector and spliceLoss = ((loss/ft) X (length in feet)) + conn. loss.

NOTI-FIRE-NET Specifications
NOTI-FIRE-NET distance limitations :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.

for NFPA 72-1993 Local Fire Alarm System a CMX module set at Loop 1, address 96 with Type ID EVGA is also required.

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 BusIn 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 ConfigurationThe wire segment for each bus connection is a transmission line.The physical construction of the twisted-pair cable used for a

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.

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.

44 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.Page 20

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
Ground LoopWaveform
Surge Waveform
DigitalSignal
How to recognize and fix ground loops It’s 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.

TH
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 => 1.1 uSec at each threshold.
