2. INTRODUCTION

2.1 GENERAL

The FP2000 offers, as an option, unsurpassed networking capabilities with Arcnet using
RS485 for rugged, reliable and peerless operation. Products from the FP2000 series can
be added and removed from the network which allows for easy expansion of the system.

• RS485 nodes are available from the network for connection to Building Management
Systems

• Remote Maintenance

• PC Based Graphic Packages

• Interpanel I/O Programming

• Remote upload/download capability

• In addition, serial ports can be configured to allow for direct access to the network.

• The following table lists the devices that can be put on the network:

FP2000 Series Fire Panels
FR2000 Series Repeaters
RP2000 LCD Repeater
UN2000 Universal Node
NA2000/NH2000 Series Network Amplifiers

Note: ARCNET is a registered trademark of Datapoint Corporation.

2.2 NETWORK OVERVIEW

The network may best be described by referring to Figure 1 which depicts a typical
network with its components.

Figure 1 : A Typical Network

The following components/products are fully compatible with the network and can be
included when designing and configuring a system:

ANY FP2000 SERIES ANALOGUE ADDRESSABLE FIRE PANEL (A)

(Refer to paragraph 3).

ANY FR2000 SERIES REPEATER PANEL/EMULATOR (Global and Local) (B)

(Refer to paragraph 4).

The Repeaters/Emulators display on their front panel the status of the fire panel(s). It also
allows all fire panel operations to be performed from the Repeater.

ANY RP2000 SERIES LCD REPEATER PANEL (C)

The Repeater Panels displays the status of the fire panel(s). It also enables some
operations to be performed on the fire panel(s).

(Refer to paragraph 4).

UNIVERSAL NODE UN2000 (D)

The Universal Node provides an access point for external systems (such as computers) to
the FP2000 Arcnet network. It also enables some operations to be performed on the Fire
Panel(s).

(Refer to paragraph 5).

NETWORK AMPLIFIER (NA2004/NH2004/NH2008) (E)

The Network amplifier makes RS485 line extension and star point connections to the
network possible.

(Refer to paragraph 6).

2.3 RS485 MEDIUM

2.3.1 General

A network can be established using fully isolated RS485 drivers as the electrical
medium for communication. The RS485 concept is a two wire "multi drop" system
that allows for bi-directional communication at high speed in noisy industrial type
environments. While providing one of the easiest forms of network interconnection,
the RS485 standard does require certain precautions when putting together a
system.

The Arcnet protocol used is a token-passing protocol and is well proven and
reliable. It is ideally suited for critical applications as each network event occurs
within a predictable and predetermined response time.

2.3.2 Multi-drop Wiring

Multi-drop wiring implies a two wire bus connected to each network node. The
recommended method is to wire the nodes in a daisy chain, where the bus enters
and leaves each node. Four terminals are usually provided (there are exceptions)
on each network component. The use of stub wiring is not recommended. Refer to
Figure 2 below for the difference between stub and daisy-chain wiring methods.

Figure 2 : Daisy-Chained and Stub Wiring

2.3.3 Bus Termination

The network two-wire bus must be terminated at each end with a resistor. The spare
terminals of the nodes at each end can be used. The value of the termination
resistor must be equal to the characteristic impedance of the cable. Links are
provided on network equipment for terminating into 120 ohm resistors. Resistors
can be added in parallel (with the links not in place) if the characteristic impedance
of the cable used is not 120 ohm. The characteristic impedance of cable can vary
quite substantially and must be taken into consideration when selecting cable for
network applications.

Beldin 9841 cable (recommended) R = 120 Ohm
Telephone cable R = 100 Ohm

Figure 3 : Bus Termination

2.3.4 Biasing

There are four sets of bias resistor links, each set consisting of two links are
provided for each of the network nodes. One link is for the RS485 positive (+) line
and the other for the negative (-) line. These links must be set on all nodes
connected to the network. The number of nodes determines the setting of the bias
resistor links and needs to be changed if nodes are added or removed from the
network. No change of biasing is required if changes to the number of nodes are
made within the groups indicated below.

Group Number of Nodes

1 1 to 6
2 7 to 14
3 15 to 22
4 23 to 32

For details on setting the biasing resistor links refer to the relevant equipment
documentation in the next paragraphs.

2.3.5 Cable Length / Type, Screening and Earthing

The maximum cable length is determined by three factors:

1. The data rate of the network

2. The capacitance/Km of the cable (both core to core and core to shield)

3. The loop resistance (core size ) of the cable
The maximum recommended length using Beldin 9841 cable or equivalent is 1500m

(1.5 km).
Twisted pair unshielded cable can be used in low noise environments, but is not

recommended.
Specification: Single twisted pair with screen and earth drain

Capacitance : 41.7 pF/m core to core

: 75 pF/m each core to screen

Characteristic Impedance : 120 Ohm

Screens of the RS485 line must be earthed at one point only. Terminals are
provided on network components to terminate and to continue the screen of the
cable.

2.3.6 Line Extensions — Star Point Connections

The Network Amplifier provides the user the ability to:

• Extend the length of the ARCNET RS485 line of the FP2000 range of fire
panels.

• Make star point connections to the ARCNET RS485 thereby increasing the
flexibility of the network cabling.

(Please refer to paragraph 6).

2.4 RS232 MEDIUM

2.4.1 General

A network can also be set up via the RS232 ports provided on the FP2000 range of
fire panels.

Typical applications are:

• Remote alarm reporting (via modem)

• Graphic package with only one fire panel

• Remote maintenance (via modem)

• Configuration of panel (using “remote maintenance manager” software)

2.4.2 Restrictions

• The maximum distance is limited (typically 10m). Distance can eventually be
increased by means of line drivers.

• The connection is always point-to-point.

Networking via RS232 between two 2000 series devices (universal node, repeaters,
panels) is not recommended; the “other” side should always be a PC or modem.

2.4.3 Connections

• When a PC is connected, a crossed cable (“null-modem”) has to be used.

• When a modem is connected, a “straight” cable can be used.

For cable configurations, please refer to Appendix A.

2.5 NETWORK INSTALLATION PARAMETERS

2.5.1 Node ID

All 2000 network devices must have a unique non-zero node identification address
(ID) to be able to communicate with other 2000 devices.

The node ID has the following structure: P/R. (Panel number / Repeater number)
There are three different kinds of node ID’s:

1. Panel:

Node ID on which detectors are connected
FP2416, FP2864, FP2432
Structure: P/0 (second part is always 0)

2. Global Repeater:

The node will be able to repeat and in some cases emulate all other programmed

panels on the network.

Structure: O/R (First part always 0)

3. Local Repeater:

The node will repeat and in some cases emulate only one panel on the network.
Structure: P/R
P : Panel ID it has to repeat
R : Number of Repeater from Panel P.

Examples:

• Fire Panel 3 : 3/0

• Global Repeater 4 : 0/4

• Local Repeater 7 of Fire Panel 3 : 3/7

2.5.2 Network Operation Mode

The maximum number of panels, local and global repeaters that can be put on the
network depends on the operation mode.

There are three (3) modes namely:
15/15 (Default Setting)

Max. 15 Panels
Max. 15 Global Repeater Panels
Max. 15 Local Repeater Panels per panel

7/31

Max. 7 Panels
Max. 31 Global Repeater Panels
Max. 31 Local Repeater Panels per panel

31/7

Max. 31 Panels
Max. 7 Global Repeater Panels
Max. 7 Local Repeater Panels per panel

The amount of nodes can never exceed 255 irrespective of the mode selected
(excluding electrical restrictions of the RS485 line) (see paragraph 2.3).

2.5.3 Port Allocation (not applicable for UN2000, NA/NH2000)

The following ports can be available for network purposes:
SER1 : RS232 serial ports

SER2 :
ARC1 : RS485 ports
ARC2 :

The ARC1/2 or SER1/2 ports on the devices are to be allocated to the Network
Communication Functions NET1/2.

None (default) - No network communications
NET1 (normally used) - All network communications set-up to NET1 will

communicate via the selected port.

NET2 - All network communications set-up to NET2 will

communicate via the selected port.
