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.

Note1:

Not all of these ports are always available on a device; please refer to the appropriate paragraph.

Note2:

Only one port can be allocated to NET1, only one port can be allocated to NET2.

2.5.4 Data Rate For the RS485 medium

The data rate should be the same for all Panels on the network. The options are:

78 Kbps 156 Kbps (default) 312 Kbps 625 Kbps 1250 Kbps Note: The UN2000, NA/NH2000 has a fixed data rate: 156 Kbps

2.5.5 Baud Rate for the RS232 Medium

The baud rate should be the same for the two devices that are communicating. The options are:

300 baud 600 baud 1200 baud 2400 baud 4800 baud 9600 baud 19200 baud 38400 baud Note: The UN2000 has a fixed data rate on the RS232 side: 9600 baud

2.5.6 Node Relationship And Fault Reporting (Not applicable for UN2000, NA/NH2000)

A FP2000 Fire Panel can be configured to communicate with any number of other FP2000 Fire Panels, Global Repeaters and Local Repeaters as allowed by the network configuration.

A Global Repeater can be configured to communicate with any number of FP2000 Fire Panels and other Global Repeaters as allowed by the network configuration. The Global Repeater will not, however, communicate with Local Repeaters.

A Local Repeater can be configured to communicate with only one FP2000 Fire Panel and not with Global Repeaters or other Local Repeaters.

For a specific panel to communicate with other panels, the status for each panel number must be set to one of the following (default is None):

NET1 check - communicate on NET1, fault warning enabled NET1 no check - communicate on NET1, fault warning disabled NET2 check - communicate on NET2, fault warning enabled NET2 no check - communicate on NET2, fault warning disabled “fault warning enabled” means that when communication fails with that specific

node, a fault will be reported.

3. NETWORKING A 2000 SERIES FIRE PANEL

3.1 RS485 NETWORK INTERFACE (NC2000)

Figure 4 : Network Interface and Associated Connection

RS485 BUS CONFIGURATION LINKS

Termination Resistor Link - J1 (see also paragraph 2.3.3) The following two possibilities exist:

• If the NC2000 is at the end of the RS485 bus: Install link J1.

• If the NC2000 is not at the end of the RS485 bus: Remove link J1.

Bias Resistor Links - J2-5; J6-9 (see also paragraph 2.3.4) There are four sets of bias resistor links, each set consisting of two links; one link for the

RS485 positive (+) line and the other for the negative (-) line. The four sets are for different ranges of the amount of nodes on a RS485 bus. The four sets of bias resistor links are divided as follows:

- Link + Link Range of Nodes J9 J5 1 - 6 J8 J2 7 - 14 J7 J4 15 - 22 J6 J3 23 - 32

Both bias resistor links of a set must be in when the amount of nodes on the RS485 bus are within that range, and out when it's not within the range.

RS485 Screen Links - J10, J11 (see paragraph 2.3.5) J10 should always be out. When J11 is in, the screen is connected to Earth (only on one node on the whole network).

3.2 SOFTWARE CONFIGURATION

Each fire panel, global repeater or local repeater on a network must be configured as follows:

3.2.1 Node Identification (see also paragraph 2.5.1)

The maximum configuration and Node ID of each panel should be set up under the menu.

SYSTEM / CONFIGURATION / ID

The Node ID consists of two digits: panel number / repeater number (p/r) The field “Panel” confirms the fire panel number. This is also shown on line 8 of the

display: P:p. For global repeaters the word “Panel” becomes “G-Repeater” and line 8 displays G:r. For local repeaters the display is “L-Repeater” and line 8 displays L:p/r.

The Max. Config. Field shows the maximum number of panels and repeaters (global or local) that can be configured. (See also paragraph 2.5.2).

3.2.2 Port Set-Up

When the RS485 medium is used, the ARC1 port should be allocated to NET1 or NET2 (default is None), under the menu System / Configuration / Communication / Port Set-up.

The options are: None (default) - No network communication NET1 (normally used) - All network communications set-up to NET1 will talk via

NET2 - All network communications set-up to NET2 will talk via

The baud rate should be the same for all panels. After the port set-up is completed, the red LED on the NC2000 should come on

steady (if there is more than one node enabled on the network). When the RS232 medium is used, NET1 or NET2 should be allocated to the SER1

or SER2 port.

the ARCNET card

3.2.3 Network Communication

The communication between nodes on the network should be enabled under the menu System / Configuration / Communication / Network. In each node, enable the node with which this node has to communicate (NET1 or NET2) and define fault warnings (check - no check).

3.2.4 Example

ID 1/0 0/1 2/0 Port ARC1=net1 ARC1=net1 ARC1=net1 Network P2:net1 no check* P1:net1 check P1:net1 no check

G1:net1 check** P2:net1 check G1:net1 check

* Panel 1 will not give a fault when comm. fails with panel 2 (the same has been

programmed on panel 2).

** Panel 1 will give a fault when comm. fails with Global Repeater (0/1) (the same has been

programmed on panel 2).

3.3 NOTES

The FP2000 series fire panels are delivered without a network card. The NC2000 must be ordered as a separate product.

4. NETWORKING LOCAL REPEATERS / GLOBAL REPEATERS

4.1 MODEL OVERVIEW

Three repeater models are available:

1. FR2032

Zone LED’s (max. 32) / 24V DC / small housing / no internal printer optional

2. FR2064

Zone LED’s (max. 64) / 24V DC / large housing / internal printer optional

3. RP2000

No zone LED’s / 24V DC / mini housing / no internal printer optional / no emulation possible

All models have the Arcnet based NC2000 on board. All of these models can be configured as a local or global repeater. When

configured as a local repeater, the LED’s (if present) will repeat the zones of the panel; when configured as a global repeater, the LED’s will act as “Panel LED’s”, i.e. Every panel on the network will have its own fire and fault LED.

4.2 RS485 NETWORK INTERFACE

(Please refer to paragraph 3.1).

4.3 SOFTWARE SETTINGS TO BE PERFORMED

(Please refer to paragraph 3.2).

4.4 EMULATION — OPERATING GUIDELINES

4.4.1 Global Repeater

Any fire, fault or conditions present on any fire panel on the network that is configured to communicate with the Global repeater will be indicated by the LED's and/or displayed by the LCD on the Global repeater. When stepping through the events on the Global Repeater the events of any Fire Panel or Global Repeater will be displayed in historical order.

Any fire panel on the network that is configured to communicate with the Global repeater can be emulated from the Global Repeater. This is done from the Panel key on the front of the Repeater. Press the Panel key followed by the number of the Panel to be emulated. While emulating a Fire Panel, the ID of that Panel will be displayed on the Global Repeater (bottom right corner). Any keys pressed during emulation are treated by the emulated Panel as if pressed on its own front panel. To exit from emulation, enter Panel 0 after pressing the Panel key. If a time-out (no key pressed for 10 minutes) occurs or if the communication to the Panel goes down, the Global Repeater will terminate the emulation mode.

All the Fire Panels on the network can be controlled simultaneously from the Global Repeater. This is done by using the ALL key on the front of the Repeater. Use this key followed by the control key required.

If the network should go down, the Global Repeater will indicate Panel faults and the Fire Panels will each indicate a Global Repeater fault (if fault warning is enabled). Once the network is restored, all the fault indications will disappear.

4.4.2 Local Repeater

Any fires, faults or conditions present on the fire panel that is configured to communicate with the Local Repeater will be indicated on the Local Repeater. All control keys on the Local Repeater are treated as if pressed on the Fire Panel.

The fire panel can be emulated from the Local Repeater. By pressing the panel key, the Local Repeater will start emulating the fire panel and the ID of the Fire Panel will be displayed on the Local Repeater (bottom right corner). Any keys pressed during emulation are treated by the emulated Panel as if pressed on its own front Panel (including the control keys). To exit from emulation press the Panel key again. If a time-out (no key pressed for 10 minutes) occurs or if the communication to the Panel goes down, the Local Repeater will terminate the emulation mode.

If the network should go down, the Local Repeater will indicate a panel fault and the fire panel will indicate a Local Repeater fault (if fault warning is enabled). Once the network is restored, all the fault indications will automatically disappear.

5. UNIVERSAL NODE UN2000

5.1 GENERAL

The Universal Node provides an access point for external systems to the FP2000 ARCNET network.

The basic function of the Universal Node may best be described by referring to Figure 5, which depicts the unit in a typical application.

Figure 5 : Universal Node Depicted In Actual Application

The Universal Node is powered from mains. It interfaces to the RS485 network via two wires and is connected to external systems by means of a RS232 cable.

Functionally it forms the interface (translator) extension for the external system and is therefore only operational while the RS232 system is in operation. It cannot operate as a stand-alone unit.

The RS232 configuration of the Universal Node is fixed while its RS485 configuration must be tailored to suit the network that it is connected to.

To change the configuration the Universal Node box must be opened to have access to the printed circuit board.

5.2 HARDWARE OVERVIEW

5.2.1 PCB Layout and Rear Panel

The rear panel and circuit board (top view) of the Universal Node is shown in Figure 6 below:

ARCNET

Figure 6 : UN2000 PCB Layout and Rear Side

5.2.2 Power Supply

The Universal Node is powered from 230V 50 Hz AC. A Power On/Off switch with an indicator lamp is also provided. The power supply is protected by an onboard fuse. (100 mA).

5.2.3 Indicators

Refer to Figure 6

5.2.4 RS485 Bus Configuration Links (See also paragraph 2.3.3)

Termination Resistor Link - J7 (see also paragraph 2.3.3)

The following two possibilities exist:

• If the Universal Node is at the end of the RS485 bus: Install link J7.

• If the Universal Node is not at the end of the RS485 bus: Remove link J7.

Bias Resistor Links - J3-6; J9-12 (see also paragraph 2.3.4)

There are four sets of bias resistors links, each set consisting of two links; one link for the RS485 positive (+) line and the other for the negative (-) line.

The four sets are for different ranges of the amount of nodes on a RS485 bus. The four sets of bias resistor links are divided as follows:

+ Link - Link

J6J12 1 - 6 J5J11 7 - 14 J4J10 15 - 22 J3J9 23 - 32

Both bias resistor links of a set must be in when the amount of nodes on the RS485 bus are within that range, and out when it's not within the range.

Earth Connection - J13 (see also paragraph 2.3.5).

If J13 is in, it connects the screen of the RS485 cable to earth. The screen must be earthed at one node only. Note that J8 must always be out.

Range of Nodes

5.2.5 Node Identification Switches (See also paragraph 2.5.1)

The Universal Node is normally used as a Global Repeater; therefore the node identification will be 0/Repeater Number.

The node identification is transferred to the switches as follows:

node ID 8 7 6 5 4 3 2 1

0/1 ON ON ON ON ON ON ON OFF 0/2 ON ON ON ON ON ON OFF ON 0/3 ON ON ON ON ON ON OFF OFF 0/4 ON ON ON ON ON OFF ON ON 0/5 ON ON ON ON ON OFF ON OFF 0/6 ON ON ON ON ON OFF OFF ON 0/7 ON ON ON ON ON OFF OFF OFF 0/8 ON ON ON ON OFF ON ON ON

0/9 ON ON ON ON OFF ON ON OFF 0/10 ON ON ON ON OFF ON OFF ON 0/11 ON ON ON ON OFF ON OFF OFF 0/12 ON ON ON ON OFF OFF ON ON 0/13 ON ON ON ON OFF OFF ON OFF 0/14 ON ON ON ON OFF OFF OFF ON 0/15 ON ON ON ON OFF OFF OFF OFF

5.2.6 General Option Switches

Switches 5 and 6 determine the ARCNET network mode and must be configured to be the same as that of the network to which the Universal Node is attached.

The meaning is as follows: Switch 5 Switch 6 Network Mode

ON ON 15/15

OFF ON 7/31

ON OFF 31/7

OFF OFF 15/15

For normal use, the positions should be as follows:

OPTIONS 1 2 3 4 5 6 7 8

POSITION ON OFF ON ON X X ON ON

5.2.7 Reset Button

By pressing this button the UN is being reset.

5.2.8 RS232 Interface

A 9-pin D-type male connector is provided. The cable must be a 9 to 9 pin, or 9 to 25-pin crossover cable. Please refer to Appendix A.

5.2.9 RS485 Interface

The connections are as shown in Figure 6. Bit rate is fixed at 156 Kbps. The FP2000 Serial Communication Format Guide is available on special request.

6. NETWORK AMPLIFIER AND HUBS

(NA2004 / NH2004 / NH2008)

6.1 GENERAL

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

6.1.1 RS485 Extension

flexibility of the network cabling.

When FP2000 Panels are distributed over a large area the RS485 signal may get attenuated to such an extend that it leads to unreliable communication. A Network amplifier overcomes this problem as it re-transmits the signal it receives whereas on a FP2000 Panel Arcnet Interface Printed Circuit Board the signal is only linked through to the next device (refer to Figure 7).

Figure 7 : Network Extension

6.1.2 Star Point Connection

Network Amplifier re-transmits an incoming signal on any one channel to all the other available channels. This feature makes star point connection possible. More channels can be added by plugging Network Amplifiers into each other (refer to

Figure 8).

Figure 8 : Star Point Connection

6.2 PRODUCT OVERVIEW

The following three (3) Network Amplifiers are available:

NA2000 NETWORK AMPLIFIER

The NA2000 Network Amplifier is a single Printed Circuit Board intended for use inside the FP2000 series of panels as it makes use of the internal power supply of the panel. Four RS485 channels are provided to enable network extension and star point connections.

NH2004 NETWORK AMPLIFIER

The NH2004 Network Amplifier is intended for external use. It consists of the basic NA2000 Network Amplifier card and a power supply mounted in a metal housing. Provision is also made for housing and charging standby batteries from mains to ensure full functionality upon interruption of power. Four RS485 channels are provided to enable network extension and star point connections.

NH2008 NETWORK AMPLIFIER

The NH2008 Network amplifier is identical to the NH2004 except that it makes use of two basic NA2000 Network Amplifier cards to provide up to eight RS485 connections.

6.3 HARDWARE OVERVIEW

6.3.2 NH2004/2008 Network Amplifiers

The NH2004 and NH2008 are stand alone units. Both make use of the NA2000 card and are provided with a mains power supply as depicted Figure 10 below. The power supply contains screw terminals for connections to the mains supply, the battery, and remote fault indication equipment. The fault indicator output consists of normally open and normally closed relay contacts (2 Amp rated). In the normal condition the Fault LED on the power supply board will be ON. The Fault LED and relay contacts indicate mains power supply or battery fault conditions. The Supply LED on the board indicates the presence of mains power when ON. The output of the power supply (24 volt), is transferred to the NA2000 card via connector TB2.

Figure 11 : Network Amplifier Configuration

Note: All the screens of the different RS485 network cables must be tied together.

6.4.2 Termination Resistor (See also paragraph 2.3.3)

Refer to Figure 11

If the Network Amplifier RS485 channel is at the end of a RS485 line:

• Termination resistor link of that channel must be in.

If the Network Amplifier RS485 channel is not at the end of a RS485 line:

• Termination resistor link of that channel must be open.

Unlike the RS485 network interface (NC2000), the Network Amplifier does not provide two sets of RS485 signal terminal block contacts for one channel. Therefore, when the network amplifier is not at the end of the channel, the two positive (+) lines terminate into the same positive (+) terminal block contact and the two negative (-) lines onto the same negative (-) terminal block contact.

6.5 INSTALLATION

6.5.1 NA2000 Installation into a FP2864 Fire Panel

(i.e. a panel with front end processor)

• The following procedures are to be followed when installing a Network amplifier:

• Switch mains power to the FP2000 panel OFF

• Select either the lower or higher slot inside the lid of the front panel to mount the

Network amplifier

• The Network Amplifier is only compatible with the following printed circuit cards:

• FP2000 RS485 Network Interface (NC2000) CE-FP-334-X

• Host PSU Board CE-FP-327-X

• FP2000 Zone Board CE-FP-322-X

• Plug the Network Amplifier in and secure in position using the hardware

supplied.

• Ensure that link J1 is removed and that J2 is in position (refer to Figure 9).

• Identify the channels of the Network amplifier that will be connected to the end

of a RS485 line (not linked through). Install the relevant resistor termination links for those channels (refer to Figure 11).

• Identify the channels of the Network Amplifier that will not be at the end of a RS485 line (linked through). Remove the relevant resistor termination links for those channels (refer to Figure 11).

• Identify the number of nodes per Network Amplifier channel. Insert biasing links in accordance with the number of nodes as specified in Figure 11. Biasing links of unused channels must also be installed (1 - 6 range).

• Connect the RS485 lines. Ensure that the polarity is correct. Only one set of terminal blocks are provided per channel. If the channel is not at the end of a line the two positive (+) lines will be terminated onto the same terminal block. The same applies to the two negative lines (-). Connect the screens of all the RS485 lines to each other.

• Note: If more than one Network Amplifier is used they must be plugged into each other.

Do not install termination links for unused Network Amplifier channels (to conserve power).

Note: Installing a NA2004 in a FP2416 is impossible.

6.5.2 NA2000 Installation into a Panel without a Front End Processor

(FR2032 / FR2064)

The following procedures are to be followed when installing a Network amplifier:

• Switch the panel OFF

• Secure the Network Amplifier on the studs provided inside the rear panel using

the hardware supplied.

• Connect the Network Amplifier plug number P5 (refer to 10) to the Power Supply (24 V DC) using the power cable supplied.

• Ensure that the link J1 and J2 is removed (refer to 10). Please note that the link J2 must be removed from the first Network Amplifier only. Additional Amplifiers plugged into the first unit must have the link J2 in position.

• Identify the channels of the Network amplifier that will be connected to the end of a RS485 line (not linked through). Install the relevant resistor termination links for those channels (refer to Figure 11).

Note: If more than one Network Amplifier is used they must be plugged into each

other. Do not install termination links for unused Network Amplifier channels (to conserve power).

6.5.3 NH2004 / NH2008 Installation

• Mount the Unit in position using the mounting holes provided.

• Ensure that the link J1 is removed and that the link J2 is in position (refer Figure

10). Ensure that a proper ground connection is made to the housing.

• Connect the unit to mains power supply using the terminal block contacts in accordance with the detail provided inside the unit.

• Install the relevant biasing and termination resistor link and connect the RS485 lines as described in Figure 11 above.

• Install the batteries. Ensure that the correct type of battery is used (refer to 6.6)

• Close the housing.

7. INTERPANEL I/O PROGRAMMING

7.1 GENERAL

Through I/O programming, it is possible to transfer any input definition from a network node to any output definition to another network node.

The communication between panels has to be enabled (with or without fault reporting) under the menu System / Configuration / Communication / Network to allow for network I/O. Network I/O can take place as follows:

Panel <-> Panel Panel <-> Global Repeater Panel <-> Local Repeater Global Repeater <-> Global Repeater

To configure a network I/O between Panels, the corresponding inputs and outputs have to be set-up in the menu Input / Output / Input Type network and Input /

Output / Output Type network.

Please refer to the FP2000 Reference Guide for more information on I/O Programming.

7.2 EXAMPLE

A fire on panel 1 should switch channel 2 of I/O Module 2/5 of panel 3. The relay should be reset with the reset of panel 1.

Notes (related to this programming table) :

• The panels are not reporting network faults from each other. However, interpanel IO is possible because of the “NET1 no check” option.

• The panels are reporting if their local repeater (if installed) is off line, but not if the global repeater is off line.

• The globals are reporting all faults, even local repeater faults ( via the panel itself)

• The global repeater (device number 4) will report if the Universal node goes down.
