The Quadnet System
The Quadnet system is an addressable intelligent detector system, with many advantages over the
traditional addressable analogue detector systems. In order to understand the benefits let us look more
closely at the terms Fire Detector and Fire Sensor. These terms are often used interchangeably but
actually have quite different meanings. A fire detector is the device (component as defined in EN54) which
automatically detects a fire. In the majority of addressable fire detection systems, the fire devices are in fact
fire sensors which only transfer data relating to smoke and heat levels to the control panel, and the fire
decision is made by the panel.
Nearly all current addressable systems are Addressable Analogue Detector Systems where the control
panel continually scans the fire sensors, processes the returned data, and makes decisions about fires and
faults.
The Quadnet system is defined as an Addressable Intelligent Detector System, or an Addressable Fire
Detection and Alarm System with Independent Distributed Intelligence. Distributed intelligence
signifies that the signal processing is spread throughout the system, in order that the decisions about fires
and faults are taken within the detector itself. The detector is capable of being remotely programmed for
different modes of detection.
Thus the Quadnet system is indeed an analogue addressable system, but with the processing power
distributed across the entire system. This dramatically reduces the complexity of the control panel and the
data traffic, and improves the efficiency of the system.
The system addressing is carried automatically upon initialisation from the control panel, and does not need
to be programmed manually at each device.
Advantages of Addressable Systems.
The nature of a microprocessor control system with individually identified devices means that the precise
location of fires and faults may be indicated, more complex actions may be implemented, system flexibility
is improved and installation and cabling costs are reduced.
In the Quadnet system, very efficient communications mean that very low quiescent power consumption
maximises the standby capacity, high power transfer capabilities allow more sounders to be connected to
the loop, and a very fast response to events is achieved as the control panel does not have to poll every
device for status data.

Control Panel
Mounting the Control Panel
Firstly identify the proposed location for the control panel. Ensure that the control panel will be easily
accessible, and that account is taken of any subsequent work that may affect access. It should be located
at the most likely point of access for the fire services.
The control panel should be mounted on a flat, vertical wall at a height where the indicators may be seen
without difficulty.
Do not locate the control panel at high level where stepladders or other access equipment may be
required, in spaces with restricted access, or in a position that may require access panels to be
removed.
Do not locate the control panel where extremes of temperature or humidity may occur, or where
there is any possibility of condensation or water ingress.
Like all electronic equipment, the control panel may be affected by extreme environmental conditions. The
position selected for its installation should therefore be clean and dry, not subjected to high levels of
vibration or shock and at least 2 meters away from any pager or radio transmitting equipment. Ambient
temperatures should be within the range given within the Technical Data section, i.e., not directly over a
radiator or heater.
In common with all microprocessor-controlled panels, the control panel may operate erratically or may be
damaged if subjected to lightening induced transients. Proper earth/ground connections will greatly reduce
susceptibility to this problem.

Topology & Cabling
All system wiring should be installed to comply with BS 5839: Pt 1: 2002: Amendment 2: 2008 and BS 7671
(wiring regulations) and any other standards relevant to the area or type of installation. A cable complying
with the BS 5839: Pt 1: 2002 Category 1 (cables required to operate for prolonged periods during fire
conditions) is required. This must be a 2-core 1.5mm
2
screened fire resistant cable (ie. MICC, FP200,
Firetuff, Firecell, Lifeline or equivalent). Ventcroft No-Burn multicore cable was utilised during the LPCB
approval testing.
The addressable circuit must be installed as a loop with a maximum loop length of up to 2 km. Addressable
spur circuits (covering up to a maximum of one detection-zone only per spur circuit and up to a maximum
of 100m in length) may be connected at each Multipoint detector, as long as the combined addressable
circuit length does not exceed 2 km.
The network cable should generally be installed as a single ring, but due to the provision of four network
ports at each panel, sub rings may be installed if required. Whilst radial circuits may be implemented
successfully, they are generally not recommended as they are less fault tolerant and lack system integrity.
Network connections must be installed with a maximum length of 500m between network ports.
The Power Supply Unit requires both a data connection and dual power connections. Thus, one x 2 core
1.5 mm
2
screened fire resistant cable must be installed between the PSU and the Control Panel for data
connections, and 2 x 1.5 mm
2
screened fire resistant cable must be installed between the PSU and the
Control Panel for 24v DC power connections if each cable is no longer than 20m (use 2.5 mm
2
for 24V DC
power cables up to a maximum of 30m).
In order to protect against possible data corruption it is important ensure the following points are adhered
to:
1. The addressable circuit (loop) cable screen must be connected to earth/ground at the
control panel at each end using the terminals provided.
2. The addressable circuit (loop) cable screen must not be connected to earth/ground at any point
other than the control panel, ie, do not connect the screen to a device back box.
3. The cable screen continuity must be maintained at every point of the loop, using the
terminals provided or a suitable connection block.
4. Do not use a 4-core cable as a loop feed & return due to the possibility of data corruption. It is
essential that two 2-core cables are used if this is required.
5. The network connection cable screens must be connected to earth/ground at the control
panel at one end only using the terminals provided.
Refer to the following wiring schematics for further details.

Loop Loading
In order to allow a method of calculating the maximum loop loading that the system will support, each
device has a rating assigned in Alarm Loading Units (ALUs). A maximum of 175 ALU are permissible on
the loop. This only relates to the load presented in alarm and does not necessarily affect an input device.
The Quadnet OSP programming software automatically keeps control of the quantity and will provide
prompts if the limits are reached.
DESCRIPTION ALU RATING
Sounder Low 0.5
Sounder Medium 1
Sounder High 2
Beacon 1
Loop I/O Module 1
Conventional Zone Module: Powered from loop 10
Conventional Zone Module: Powered remotely 1
Note: Whilst the system will operate a maximum of 800 devices per control panel, for compliance with
EN54: Part 2: 1997 Amendments 1 and 2, it is recommended that a limit of a maximum of 512 detection
devices is adhered to. This includes detectors and manual call points, but does not affect the number of
sounders or other alarm devices on the system.

The Loop 1-4 addressable circuits may be connected to the appropriate End 1 and End 2 terminals.
Communications normally run from Circuit End 1, but in the event of a continuity fault both ends of the
circuit will operate.
It is important that the cable screen is connected to earth at each end at the control panel only, and that the
screen continuity is maintained at all times. We recommend against the use of a 4-core cable as a loop
Feed & Return due to the possibility of data corruption.
Addressable spur (radial) circuits may be connected from any multipoint detector, but not from any other
device. Devices covering a maximum of 1 zone per spur connection may be connected to each circuit in
order to ensure that no more than 1 zone may be lost in the event of a cable failure. Full functionality is
maintained for all spur devices.

Mains Supply & Batteries
The Fire Alarm Panel 230V AC supply requires fixed wiring between 0.75 mm
2
and 2.5 mm
2
, a 3 amp fused
un-switched spur with local isolation, to be terminated into the fused terminals provided in the power supply
back box. The mains supply should be dedicated to the Fire Alarm Panel and should be clearly labelled
‘FIRE ALARM: DO NOT SWITCH OFF’ at all isolation points.
The standby will vary depending on the system loading, requiring up to a maximum of 2 x 12v 17Ah sealed
lead acid batteries. These are to be sited in the power supply back box in the provided enclosure along the
bottom edge. The batteries should be connected in series using the connection leads supplied. We
recommend the use of type Yuasa NP3.2-12 (FR) or other equivalent approved type.
Note that batteries are electrically live at all times and great care should be taken to ensure that the
terminals are never presented with a short circuit. Care should be taken at all times, especially during
transit, installation and normal use. Use caution as there is a risk of explosion if the batteries are
replaced by an incorrect type.
Batteries no longer required should be disposed of in a safe and environmentally friendly manner by the
manufacturer or a suitable recycling service. They should never be incinerated or placed in normal rubbish
collection facilities. Dispose of used batteries according to the instructions.

Network
Topology and cable spec
The Quadnet network may be connected as shown below. The network may comprise of Control panels or
repeater panels as required, up to a maximum of 32 nodes. In addition to the connections shown above,
each panel will require a 230V AC supply and the power supply arrangements relevant to that panel.
Any network port at a Control Panel may be connected to any other network port at any other Control
Panel. A list of these connections must be noted during termination as they will need to be configured t
each Control Panel for correct operation.
The Network connection circuit may be installed as a radial, star, ring or mesh network, with a maximum
cable length of up to 1 km between network nodes. It is recommended that the ring or mesh configurations
are used to ensure system integrity in the event of a cable failure.
All system wiring should be installed to comply with BS 5839: Pt1: 2002: Amendment 2: 2008 and BS 7671
(wiring regulations), along with any other standards relevant to the area or type of installation. A cable
complying with the BS 5839: Pt1: 2002: Amendment 2: 2008: Category 1 (cables required to operate for
prolonged periods during fire conditions) is required. This must be a 2-core 1.5mm
2
screened fire resistant
cable (ie. MICC, FP200, Firetuff, Firecell, Lifeline or equivalent).
The network circuit should be installed as a loop with a maximum length of up to 1 km between network
nodes (panels etc). Radial circuits may be utilised, but the system integrity and fault tolerance will be lower.
In order to protect against possible data corruption it is important ensure the following points are adhered
to:
1. The cable screen between each network node (panel/repeater) must be connected to
earth/ground at one end only using the terminals provided. Ensure that the end that is not
connected is safely terminated in a connector block to avoid unwanted shorting to any other
point.
2. The cable screen between each panel/repeater must be connected to earth/ground at
one end only using the terminals provided. Ensure the end that is not connected is safely
terminated in a connector block to avoid unwanted shorting to any other point.
3. Do not use a 4-core cable as a loop feed & return due to the possibility of data corruption. It is
essential that two 2-core cables are used if this is required.

Commissioning
Installation 1
st
Stage
The installer/contractor needs to install the system wiring in the form of 2-core and earth/screen loops
returning to the control panel. Addressable spur circuits may be installed from a Multipoint detector
covering up to one zone using the Spur +ve &Spur –ve terminals.
The cabling should be 2-core 1.5mm
2
, screened and fire resistant, of an MICC or FP200 equivalent type.
We recommend against the use of a 4 core cable as a loop feed and return, due to the possibility of data
corruption.
The loop should be left as a complete loop with no devices connected, and must be tested and
documented for conductor continuity and for insulation integrity, with a high voltage tester (using the
shorting links provided within each base to provide continuity in the positive core), as required for general
electrical installations.
The control panel back box should be mounted, with the mains supply tested, connected and isolated at the
un-switched fused spur, ready for the commissioning engineer.
The installer needs to provide a set of As-Wired drawings, completed configuration sheets and proof of
loop continuity and insulation test readings etc., to enable commissioning to proceed. This information
is essential for commissioning and programming to proceed, and may be entered onto the forms provided
at the rear of the manual.
Installation 2
nd
Stage
Once the commissioning engineer is satisfied with the continuity / integrity of the loop, the devices may be
installed, noting the serial numbers for each device on the configuration sheets.
Commissioning
Commissioning the Quadnet system involves powering up the system, programming the configuration and
testing for correct operation.
Configuration of the system requires the Quadnet OSP software package, and should only be carried out
by a suitably approved commissioning engineer.
