OVERVIEW
INTRODUCTION
This document covers the installation and commissioning of an NODE+ fire alarm panel. This document is intended for use
by a competent, qualified, fire alarm installation engineer. The NODE+ fire alarm system should be tailored to the building
requirements. The complete system should be designed to meet all applicable regulations. The installation must then be
performed in accordance with the system design. This manual not only clarifies the components and connections during
installation but will also assist in commissioning and maintenance. This manual covers the installation and commissioning
of a complete system excluding the communications system. Please refer to the Chameleon Network Manual.
IMPORTANT NOTE:
NODE+ does not have an User Interface (UI), so all interactions can be performed by accessing NODE+ through the UI of
another Panel on the network. To access the NODE+ settings you must have an external UI. NODE+ has identical
functionality to OCTO+ with the exception of the UI.

loss resulting from a fire.
The fire alarm system should be designed and installed in accordance with all relevant regulations and codes of practice.
To ensure maximum protection, the system should be regularly tested and inspected by qualified fire alarm installation
personnel. Inspection and testing should be carried out in accordance with the appropriate local standards.
NODE+ / Installation & Commission Manual / © GFE 220331 11

TERMS, DEFINITIONS AND ABBREVIATIONS
Analogue Loop - The physical link, usually fireproof 2 conductor shielded wiring cable, forming a ring of interconnection.
Flat Cable - A 5 way connecting lead. Typically a length of flat cable with connectors at both ends.
Conventional Sounder - A Conventional Sounder is an audible output device that is connected to the Conventional
Sounder outputs on the Panel. It is different electrically from a Loop powered Sounder.
Serial Communication - Communications using RS422, RS232, Fibre-Optic link or TCP/IP Serial Tunnel. It provides
communications between the Panels. Chameleon Network uses Serial Communication, under a different physical layer as
standard.
Detector - Any type of fire sensor (heat, smoke) that is connected to an Analogue Loop.
Device - A detector, sounder, interface module or call-point connected to an Analogue Loop.
Evacuation - A system state where all sounders are activated simultaneously. Pressing SOUNDERS ACTIVATE/SILENCE will
generate a system evacuate condition.
Fibre-Optic Link - A connection method for data that uses light instead of electrical signals. The connection is made using
fibre-optic cables rather than copper electrical cables. Fibre-optic signals can travel far greater distances than electrical
signals, with less risk of electromagnetic interference.
Flash - Non-volatile memory inside the panel used to store the program, local NVRAM memory and Customer data
memory. Flash data storage is very robust and needs no power at all to retain the data.
Local Sounder - A local conventional sounder is an audible output device (bell or sounder) that is connected to the local
bell output on the panel.
Loop Sounder - The term Loop Sounder is used to describe an audible output device that is connected to and controlled
individually by an Analogue Loop. Loop Sounders are different electrically from Conventional Sounders.
NVRAM - Non-volatile Random Access Memory. Any information stored in this memory will not be cleared when power is
removed from the system. It contains the LOG info, disablements and system state info.
PCB - Printed Circuit Board.
Chameleon Display (panel repeater) - Everything displayed in the OCTO+ “Front End” is also displayed to the “Chameleon
Display”. Every key press action is made as if the input was actually occurring on the connected “Front End” panel. This is
not a network panel and is used to add one extra Display to a specific panel. It mimics the connected panel. It has no
network capabilities.
Chameleon Repeater (system repeater) - In a Chameleon Network, the CHAMELEON REPEATER is used as a “System
Repeater”. It works as a networked panel (but without loops connected) and has the ability to process and register all
“system info” (it has a dedicated event log). Everything that is displayed in any networked panel, with the exception of
zonal LEDs, will be displayed on the Repeater Panel. This is a full feature network panel. It occupies an address on the
network and can be interleaved with the communication closed loop, since it has network capabilities.
The System - All wired networked panels (GEKKO, OCTO+, NODE+ or CHAMELEON REP).
Zone - A situational group of devices. A Zone can consist of a collection of any of the devices connected to the system.

INSTALLATION
INTRODUCTION
This section covers the physical installation of the system. It primarily focuses on the parts that are required and how they
should be connected together.
NOTE: Do not connect the mains power or the batteries at this stage; commissioning the system is covered in the next
section of this manual. Installation should always be performed in accordance with a system plan.
CONTROL PANEL
The control panel should not be located where access to the internal components are restricted and where the unit is
exposed to high levels of temperature, moisture, vibration and shock.
Any metal swarf could damage the PCBs. If any metal is present when the system is powered up, it is recommended that
all PCBs are removed from their box whilst the box is being installed. Make a note of the positions of the PCBs before
powering up the system
MAINS POWER CONNECTION
All panels must be earthed. The LIVE connection must be made to the fused input on the power supply module and will
have a Black or Brown wire leading into the power supply unit. The connection with a Blue wire leading into the power
supply unit is the NEUTRAL. The Yellow/Green wire is the EARTH.
REPEATER PANELS
Repeater Panels can be used. There are two options available:
1. The Chameleon Display (isolated panel repeater): Specific panel “extra display”.
2. The Chameleon Repeater (system network repeater): Used interleaved with the closed communications loop.
It's a full featured “global” system repeater. It occupies an address on the network and behaves like a network
panel but without devices plugged.
Both repeaters don’t have a dedicated power supply. Each NODE+, is able to supply power to four repeaters. For more
units an external power source must be added.
They should not be located where access to the internal components are restricted and where the unit is exposed to high
levels of temperature, moisture, vibration and shock.
Avoid placing repeaters in direct sunlight as this may impair reading of the LCD display.
Any metal swarf could damage the PCBs. If any metal is present when the system is powered up, it is recommended that
all PCBs are removed from their box whilst the box is being installed. Make a note of the positions of the PCBs before
powering up the system.

NODE+ Loop Card Fitting
●This operation should only be performed by qualified personnel.
●Power to the panel should be completely removed, both primary and secondary (batteries) supplies,
before the installation process of the card is initiated.
●After the process is completed, re-apply power to the panel.
2 Male 20-way headers and 1 Male
8-way headers on the expansion board
should fit into the corresponding
female headers situated at the back of
the panel's main board.
Use 4 units of M3 x 5 mm screws
provided to fix NODE Expansion Loop.
COMMUNICATION CHANNEL DETAIL
The NODE+ Panel is designed to work integrated on
Chameleon networks. Any of the following Chameleon
networked panels can be interconnected: OCTO+,
GEKKO, NODE+ and CHAMELEON REP.
Different physical layer interfaces can be used such as
RS422, Fibre Optic or TCP/IP connections.
RS422 may be used for distances of up to 1200m.
For longer distances (up to 4,5 km) Fibre Optic Data
connections should be used. See page for cable
requirements for both types of installation.
Repeater Network Options
When you have an NODE+ integrated in a Chameleon Network system, the need for “network redundancy” should be
respected. To be able to achieve this, and as much as possible, system repeaters CHAMELEON-REP should be interleaved
on the network and connected in a “daisy chained” closed Loop topology, thus protecting the Data from interruptions,
creating a bi-directional communications path. If the panel loses communications with the repeater in one path, the
message will arrive via the opposite path.
NODE+ / Installation & Commission Manual / © GFE 220331 15

Nevertheless, by having the NODE CH1 and CH2 occupied getting the closed “daisy-chained” data loop connected, the
extra CH3 can be used to extend with a lower cost “Panel Repeater” using the Chameleon Display.
NODE+ / Installation & Commission Manual / © GFE 220331 16

NOTE: The CHAMELEON-REP has its own network address, and it is considered a Network Panel, acting as a system
repeater. It records all received network events into its own LOG.
NOTE: The CHAMELEON DISPLAY does not have a network address. It is a simple extra display, without any network
processing capability, acting only as an extra display of the connected panel.
UI Connection
To connect a UI to a Node+ the user can connect one of the channels ( CH1, CH2 or CH3) of the UI to the “Display” channel
of the NODE+.
Chameleon Displays and Repeaters are installed in a similar manner to Control Panels.
Since the Repeaters don’t have a dedicated power supply, they can be connected to any NODE “Aux Power Supply”. Each
NODE+ panel can power a maximum of 3 CHAMELEON REP or 3 CHAMELEON DISPLAY.
NOTE: For more detailed information on the network topologies please refer to
the “Chameleon Communications Manual”.
NODE+ / Installation & Commission Manual / © GFE 220331 17

ANALOGUE LOOP(S) DETAIL
The Analogue Loop provides the connection to all the analogue
addressable devices and loop powered sounders. Unless the loop
return is closed and completed, the panel will not be able to
monitor its integrity (open and short circuit monitoring).
Devices that can be fitted to the Analogue Loop include smoke
sensors, heat sensors, Zone Monitor Units (ZMU’s), I/O units, loop
sounders and manual call-points.
Refer to the devices manual for connections diagrams. If no manual is available, make the connections as shown below:
NOTE: A maximum of 32 manual call-points can be fitted into an Analogue loop. If this value is exceeded, the response
time for certain types of call-point will be excessive.
For Integrity of transmission paths it is recommended the usage of short-circuit isolators on the Analog Loop.
Such application is directly related with the installation physical layout and should be applied accordingly in a way to limit
the consequences of faults in the Analog Loop.
The accepted consequences of faults using short-circuit isolators are specified in national guidelines for planning, design
and installation of fire detection and fire alarm systems (codes of practice), etc. and may be different in different
countries.
Nevertheless it is recommended never to exceed 32 detection devices on the same path or zone without the usage of
short-circuit isolators. Meaning that in an event of a short-circuit, no more than 32 detection devices should be affected.
For isolator devices recommendation, search “isolators” on our website. Isolator example: GFE-AD-ISO.
CONVENTIONAL SOUNDERS DETAIL
Conventional Sounders is the term used to describe conventional alarm sounders (or
polarized bells) connected directly to a Panel. Loop-powered Sounders are different
and are connected to the Analogue Loop.
Two Conventional Sounder circuits are provided on the Panel. More than one
Conventional Sounder may be connected to each circuit. Total Max. Current
rating/Output is 500 mA @ 28.5 V DC nominal.
All Conventional Sounder circuits are monitored for open and short circuit faults. If a
Conventional Sounder output is not used, then a 10K resistor must be connected
across its output terminals.
WARNING:
The total current load of all detection loops, sounder circuits and auxiliary supply outputs should not
exceed the maximum power rating of the panel. Please refer to the technical specification tables.
NODE+ / Installation & Commission Manual / © GFE 220331 18

AUXILIARY FIRE RELAYS (2) AND FAULT RELAY (1) DETAIL
Two auxiliary fire relay outputs are provided on the NODE board. These
outputs are activated when a fire is detected (unless specifically inhibited).
They are labeled AUX1 and AUX2. Under the presence of any Fire Alarm
condition, these 2 relays will be energized. Both sets of contacts are of the
change-over type. Max. Contact current rating for each set of relay contacts is 2
Amp @ 30 V DC resistive / 0.5 Amp @ 120 V AC resistive.
One auxiliary fault relay output is also provided. This relay output will remain
closed while there are no faults present in the system. Under any fault
condition present, the relay will be de-energized and the relay contact will be
open. The Fault relay is NC and will open on any fault on the system.
The contact ratings are: 2 Amp @ 30 V DC resistive / 0.5 Amp @ 120 V AC resistive.
WARNING:
Relay outputs are not supervised.
Please ensure that any wiring connected to these outputs is power limited.
PANEL BATTERIES DETAIL
It is recommended that the batteries are fitted at the end of commissioning the system. Otherwise it can be difficult to
remove the power quickly if there is a problem.
The batteries are connected to the NODE circuit board. This battery connection not only supplies the panel with power if
the primary supply should fail, it also provides a charging output to maintain the batteries in a fully charged state.
Before connecting the batteries check the voltage across the battery connection terminals. It should be 27.5V +/- 0.5V.
NOTE: Arcing and fire risk. Never short circuit the battery terminals.
Always connect the blue wire between the batteries last.
NOTE: Place the batteries and cabling
inside the box according to the above
diagram. The cables should follow a path
as close to the metal bottom chassis as
possible. Both positive and negative
cables should also be slightly twisted, in
order to follow together into the
terminals.
