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 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.

Page 10

21


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.

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.

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.

Characteristic Impedance in a Point-to-Point ConfigurationWire 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

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

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.

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

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.

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.
