NFN Network Description Peer-to-peer network Minimum hardware requirement for NFN

2 nodes connected via wire or fiber Supports 103 Nodes with a maximum capacity

of 324,360 points. It will support up to 54 nodes when it is set

up to circulate digital audio messages from a DVC node.

Each node requires a unique address and it communicates with other nodes via a network interface board.

Network Communications Module(NCM)

Connects to the NUP (Notifier Universal Protocol) port on Onyx Fire Alarm Panels, NCA, NCA-2 and DVC.

Each NCM on the network MUST be running the same version.

Network Configurations NFN is capable of communicating using

two types of wiring styles, style 4 and 7. Style 4

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

Style 7 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.



Point-To-Point Configuration Wiring a Noti-Fire-Net in Style 7 point-to-point.



Point-To-Point Configuration A 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 the beginning and the end of

every segment and are built into each MIB/RPT/NAM232. Termination is done with slide switches on the NCM/NCS-

NCW/NFN-GW-PC-W.Terminate Terminate Terminate



Bus Configuration A bus wiring configuration is defined as a twisted pair

network with more than two nodes. Termination is only required on the FIRST and LAST

node of the bus. Remove termination on the middle nodes of the bus.

Network Wiring Requirements When designing the wiring layout of a

NOTI-FIRE-NET system, the following limitations must be considered:

1. The length of each individual twisted pair or fiber optic network communication circuit segment is limited.

2. The system path length is limited.

Limit for Fiber Optic Circuits The attenuation of cabling between two nodes/repeaters is limited

by cable choice.

Fiber optic circuits are point-to-point only, NO Star or Bussing is allowed.

Use repeaters (RPT-F) to extend segments.

Attenuation limits for multimode fiber: 62.5/125m cable = 8dB limit 50/125m cable = 4.2dB limit Use industry standard equipment using a test wavelength of

850 nanometers to calculate dB loss.



Calculating approximate dB loss1. Calculate loss due to cable look up the rated dB

loss per foot from manufacturers specifications. Multiply this by the length of cable between 2 nodes/repeaters to determine loss due to cable. (Loss/ft x length in ft)

2. Calculate loss due to connectors/splices Look up the dB loss for each connector and splice. Add all figures to determine loss due to connectors/splices.

3. Calculate total loss Add the attenuation factors obtained in steps 1 & 2. This will provide an approximate attenuation total.



Calculating approximate dB loss2. Calculate loss due to connectors/splices

Look up the dB loss for each connector and splice.Connectors = 0.3 dB loss for most adhesive/polish connectors.

0.75 dB loss for most prepolished/spliced connectors.

Splices = Typically 0.3 dB loss for each splice

1.Add all figures to determine loss due to connectors/splices.

E.g. There are two prepolished connectors and one splice between the networked nodes

(0.75 + 0.75 + 0.3) = 1.8 dB loss



Calculating approximate dB loss3. Calculate total loss

Add the attenuation factors obtained in steps 1 & 2. This will provide an approximate attenuation total, which should be 8 dB or less for the standard NFN.

Step 1 (.001 x 1800) = 1.8 dB lossStep 2 (0.75 + 0.75 + 0.3) = + 1.8 dB loss

Step 3 Approximate total loss = 3.6 dB
