1. Introduction
is a mesh networkable product which enables a fully redundant network of
devices to be constructed. The network topology requires a minimum of two
devices to be connected to create a network; as more devices are added
network redundancy is improved until full redundancy is achieved. Integrated inputs and
outputs (I/O) enhance the Network’s ability to respond to events and actuate devices.
A network is a standalone network of devices that inter-communicate,
managing the distributed I/O. Each device is supervised, which ensures that, when a
deviceislosttothenetwork,anoticationissentsothatthenetworkcanbemaintained
to mitigate the loss.
1.1.1. Architecture
1.1.2. Security and Management Features
is comprised of two
elements:
1. The network, which enables
communication between
devices as both a receiver and a
transmitter.
2. The distributed I/O of which each
device has one input
and one output.
When a factory fresh device is powered up, it does not yet belong to a
network of devices. The device can either be added to an existing network or
beusedasaninitiatortocreateanewnetwork.Oncecongured,a device
retainsitscongurationevenwhenpowerislosttothedevice.
The network is initiated on a WiZo; which requires that one WiZo be elected as the
temporary mesh network master. As soon as a second WiZo joins the network, there is
no longer a need for the master role and it falls away, with the WiZo devices determining
the best message transmission route. As additional WiZo devices are added, the network
management is delegated amongst the WiZos, building up the mesh until it reaches full
network redundancy.
When a mesh network has been initiated and then federated, the devices
belong to a secure network with 128 BIT encryption. Additional nodes can only be added
to the network if one of the devices on the network is placed into “Add Node” mode.
This requires physical access to at least one device.
FIGURE 1. NETWORK ARCHITECTURE
RADIO FREQUENCY 2.4GHZ

Owing to the federated nature of the network, when one device
is placed into “Add Node” mode, this places the mesh network of
devices into “Add Node” mode.

Once WiZo devices has been purchased, the user may be evaluating the installation
from one of two angles. Firstly, as an existing CENTURION customer who already has an
existing CENTURION product, or products, in operation, or secondly as someone new to
CENTURION’s product range wanting to get the most value for money out of his or her
purchases.
If you are an existing CENTURION customer, the enables you to enhance
your existing product investment. Each device adds distributed I/O which
can be used for several applications. Since the devices form a Mesh-able
Network, each new device improves the network strength. This is implemented with no
need for further infrastructure investment. Provided the device has power, and is able to
connect to the mesh network, it functions as an interconnected device enhancing network
capabilities.
If the user is a new CENTURION product customer, please keep in mind that WiZo-

product range. forms a standalone network of devices, which has the option
of integrating via the G-ULTRA GSM unit and the G-REMOTE mobile application to be
activated and used as an interface to the network. This is, however, not a
requirement, and the network,oncecongured,willself-manageand
self-heal, functioning independently and reliably.
The WiZo network is a standalone network, which may consist of up to 50 or more
individual units. The network is constructed of devices, which are nodes on
the network. Once a device is added or allowed entry, the device is trusted
and is managed as a node on the network.
As a node, the improves the strength of the network by;
1. Adding an additional path or hop to the network.
2. network redundancy is improved.
3. additional I/O is added.
A single WiZo device does not form and cannot form a mesh network; a
minimum of two devices is required.

NETWORK REDUNDANCYSECTION 2
Full network redundancy takes full advantage of the mesh network integrity by ensuring
that the message that needs to travel will reach its destination. Redundancy can be
achieved with three devices or more. The device will continue to deliver the
mostrecentmessage,indenitely,untilthemessageisdelivered.Whenthemessage
is delivered, an acknowledgement is returned; all messages sent have end to end
acknowledgements.
In a mesh network, each device is connected to every other device in the network. In
an ideal environment, transmission is always perfect, and the message always arrives
intact.However,inpractice,manyfactorsinuencesignaltransmissionandthemesh
network principles and topology ensure that the message will always be delivered to its
destination. This is achieved by;
1. Line-of-sight or a direct connection,
2. through routing via adjacent devices.
The network strength or health is indicated locally at each device.
As shown in Figure 2, node A has
a direct line-of-sight connection to
node C. Node A can also route its
message via node B or node D to
reach node C.
The message has three routes
through which it can travel, which
guarantees that the message is
received, unless there is total
network failure.
Partial redundancy is achieved when
a node has at least one alternative
path to deliver its message to the
target device.
As shown in Figure 3, A has a line of
sight to node C. If the line of sight
is interrupted, the message will be
redirected via the mesh network via
node B.

Although two devices are
required to form a basic network,
this does not constitute a mesh
network. Node A has direct line-
of-sight to Node B and Node B the
same for Node A; if there were
interruption, there is no alternative
path for the message to be
delivered.
When planning the network, a few essential elements must be considered before
physically installing each device or node. Since the is a wireless
device, physical installation is minimal, and this does allow for moving elements around.
However, sensible planning to begin with will ensure that the network is set up and
installed with minimal errors or issues.
When planning the network, it is important to consider the paths that are
available for a message to travel from one point to another. It is possible to create a
network where there is a combination of full- and partial-redundancy. When travelling,
the message may have line-of-sight from source to destination node, or the message
may be routed via multiple nodes before it reaches its destination. The
devices determine the best route to deliver the message, and good network planning
goes hand-in-hand with this process to ensure that the devices have enough available
paths to ensure that the message is delivered.

the mesh network.
When mastering the network, mastering onsite has the advantage of the master
selecting a channel that has low energy and minimal interference from other RF
devices or even an adjacent network.
Redundancyisaectedbythedistancebetweennodesaswellastheavailability
of nodes. This can be impacted by obstructions, where although the devices
are close enough, or there are enough nodes on the network, the interference
prevents the signal from being transmitted or received.
More than one WiZo Network can coexist on the same channel, provided they
are not in permit mode at the same time, which will interfere with federation.
page 9 www.centsys.com
NETWORK REDUNDANCYSECTION 2
Shown in Figure 5 below is an example network, which links several common devices
into a mesh network. Owing to proximity, certain devices have more than one path to
transmit and receive messages, whereas other devices do not. It is not always possible
to install the in an ideal location to guarantee optimal signal strength;
therefore, it is important to plan carefully to ensure that, as the installer, the devices are
not installed in such a way as to reduce signal strength, but so that signal strength is at
its best.

When the mesh network is fully redundant two green LEDs will
illuminate in the NET area on the PCB. If only one is illuminated, this means
that the user does not have full network redundancy.
‘Lost’ refers to any number of eventualities which includes: device(s) struck by
lightning, power loss, etc., and does not necessarily refer to device failure.
The above example consists of the following:
A home which has the following devices near,
• Geyser
• JoJo Tank
• Borehole Pump
• Outbuilding Geyser
Devices which are further away from the home are,
• Garage Door
• Gate Motor
page 10
www.centsys.com
NETWORK REDUNDANCYSECTION 2
If, for example, the Garage Door WiZo was lost there would be no link between the
devices installed in the actual home and the gate motor as there was only one path
between the fully-redundant network and the adjacent nodes.
The devices located in the area around the home have higher redundancy, and they will
continue to function as a mesh network. To create a bridge or additional path to avoid
meshed failure, a can be installed and used as a repeater. Since each WiZo-
already functions as this in its usual role, once joined to the network this role is
fullledwithnoadditionalsetuprequired.
• If one notes in Area A, these devices all have full redundancy as there are
multiple paths available to deliver the message
• However, in Area B, i.e. the distance between the Gate Motor and the Home

We recommend that the not be installed in the following locations:
• Metal enclosures, which dampen signal
• Metal includes ferrous and non-ferrous
• Steel, mild steel, etc.
• Aluminium
• The device should not be installed on a metal base or other materials that can absorb
or dampen signal, and should be at least 100mm (See above)
• In area C, we do have partial redundancy; however, the number of paths for adjacent
nodes is limited
• In area D, a WiZo has been used as a repeater. This increases network strength by
adding in the additional path ensuring that network redundancy has been achieved
If the red LED illuminates in the NET section, the WiZo has lost signal and, if
the Amber LED illuminates, there is weak signal.

The unit has an omnidirectional antenna on the PCB. This antenna has
a small surface area and, since it operates within the RF band, this means that it is
susceptible to interference. When installed, a few precautions must be observed to
ensure minimal interference exists.

The key strength of the systemisthatinputsofonedevicecanbecongured
to drive the outputs of one or many devices. These relationships will be discussed in
more detail in the next section.
Each WiZo is equipped with one input and one output:
Inputs and outputs are used by electronic devices to interface and interact with people
and systems; in other words, the “outside world”. An input allows the outside world,
whetherapersonpushingapushbuttonor,forexample,aoatswitchonaJoJotank,to
send a signal. That signal indicates to the system that a change has taken place and that
change must translate into an action. The action takes place when the actuator or output
is activated.
Keep in mind that the output on the is a low power type output, and it is
used to ACTUATE the output system and not to drive the output system. This is referred
to as relay action, where a low-powered system drives or actuates a high-power system.
3.1. What are inputs and outputs?
Examples of inputs are:
• Pushbutton
• Float switch
• Proximity device, Alarm panels, Energisers, Gate motors.

theinstallertocongureonedevicetoactuateitownoutput,butalsotheoutputsof
other devices.
The input is an active low-type. This means that the change in the signal is recognised
when the level of the input goes from high to low or from 12V to 0V. As shown
diagrammatically in Figure 6 below, when the button is pushed the active low signal is
detected, and the unit determines which output to activate. That output is
located and activated.
The outputs are activated in one of two ways: Normal mode or latch.
Normal: Means that, when the input is activated, the output stays active so long as the
input is active. If the input is inactive, then the output is inactive.
Latch: Means that when the input is active the output goes active and stays active even
if the input is inactive. The output will only go inactive if the input is activated again.
See Tables 4 and 5 below for a visual description:

The key feature of the device is to actuate the outputs of adjacent devices or
devices at some distance wirelessly; while still able to actuate its own output.
In other words, there is no need to run extended cabling to activate, for example, a gate
motor. The with the dependable mesh network, guarantees that the link or
connection between devices stays active and can reliably be actuated at any time.

therefore, the user / installer must do the following:
1. Create a Master Device to create the network.
2. Add additional WiZos until the mesh network is created with either full or partial
redundancy.
Follow these steps to ensure that the WiZo is not part of a network,
i.e. in its default network state.
Pre-step
1. Ensure that the WiZo is powered down, and has been without power for at least
20 seconds.
2. Locate the NET and I/O tactile switches.
They are located at the edge of the board, next to each other.
Start
1. Applyrm,evenpressuretoboththeNETandI/Oswitches.
2. Keep them depressed, and power up the WiZo.
a. The power LED will illuminate.
b. and four other LEDs will pulse and the device will emit a slow buzzer pulse.
3. Allow the device to remain in this state for at least 10 seconds. The slow pulse will
change to a rapid buzzer pulse. This indicates that the device has been master reset.
4. Release the NET and I/O buttons.
To establish the network, one temporary master must be created. Once the network has
been created, additional devices are added and once this happens, master control is no
longer required and is delegated amongst the devices in the network.
Pre-step
1. Ensure that the WiZoisnotalreadyconguredaspartofanetwork.
If so, one can master reset the device, as above.
2. Locate the NET and I/O tactile switches.
They are located at the edge of the board, next to each other.

1. Power up the device, allow for 5-10 seconds for the power supply to stabilise.
2. Locate the NET button, and depress.
a. There will be one beep, keep holding the button,
b. Hold until two beeps are heard,
c. Release the NET button. A rapid succession of beeps will be heard.
The network master step needs to take place only once, on one device, and is
not needed again unless one is re-establishing the network.

already Federated (added to a network) and cannot be used as a master unless
it is master cleared or reset.

Mastering a WiZo for a new network needs to happen only once. As soon as one other

In other words, even if the Master falls away, the network remains functional and can be
expanded.

Pre-step
1. Ensure that all the devices that the user wishes to add have been master cleared and
have not previously been added to another network.
2. Ensure that the temporary master has been powered up.
3. Ensure that the WiZos (more than one can be ready) are powered up.
Start
To add new devices, start with the Master WiZo or any device already added if there is
more than one, and do the following;
1. Press and hold the NET button until a single beep is heard.
2. Release the button and all Federated WiZos will beep simultaneously; this indicates
that the network is in Federated mode.
3. Using a WiZo that is not currently added to any network, press and hold the NET
button until a single beep is heard.
4. Once released, the WiZo will search for the network and, once it adds the devices,
