1. Introduction
This guide is designed to provide documentation for users and technical staff
who will install, configure, maintain, and set the software up on desktop and
tablet computers, and use it daily, covering the functionality of every available
element and feature, most basic needs and answering most questions that would
assist them in solving issues and difficulties.
Note: For a clearer understanding of this user manual, it is recommended that
chapter 1.3.1., containing a list of useful keywords and terms that are being
repeatedly used throughout the document, be advised.
1.1. Specifications & Features
The product’s architecture can be broken down to the following elements, or
specifications: the database, API, worker, data receiver, Modbus, and User
Interface that essentially is the primary element the present manual describes.
The following image provides a simple overview of the system’s architecture.

6
(i) Database – The database is installed along with the main software
application. The engine powering the database is the Microsoft SQL Server 2019
software. The database serves as the main storage location for several
procedures, the devices’ status and information, and floor plan files among
others.
- The database has a limit of 10GB of storage, depending on Microsoft’s
specifications.
- Only one database is required for the entire network of wireless devices, and it
can be installed on a single computer.
(ii) API– The API is built using the .NET 6 technology. It communicates with the
database using a connection string, which is a string that specifies information
about a data source and the means of connecting to it. All queries placed to the
database are carried out through the Entity framework, using ORM. It serves as
the bridge for the communication of each separate element with one another.
- It can be installed anywhere on the network and is installed as an always-on
service in the background.
- All calls placed to the API use the HTTPS protocol utilizing a self-signed
certificate.
(iii) Worker – It is a Windows service built with the .NET 6 technology. Its
purpose is to receive specific information from the tables of the database and
record and store it in another table that will facilitate the UI and serve as a
summary.
- It checks for any scheduled tasks or procedures that are selected by the user to
ensure their successful execution.
- It utilizes the SMTP protocol and other e-mail services to distribute general
reports and notification messages to the software’s users.
(iv) Data receiver – It is a Windows service built with the .NET 6 technology. The
data receiver is installed on the main computer and is responsible for all
communication between the installed gateways and the wireless points –
luminaires and I/O units – for the transmission of the various commands the user
may send. It records and stores the status of those devices in the database.
- It is installed as an always-on service in the background.
- All requests are being monitored in real time.
- The tasks assigned to devices through user commands may be programmed or
ad hoc created.

7
- Multiple data receivers can be installed – one receiver per installed panel – on
multiple computers within the same network, while enabling their communication
with the same database through the API.
(v) Modbus – It is a Windows service using the .NET 6 technology, responsible
for the Modbus protocol implementation in the software. More information can be
found in chapter 3.1.7.5.
(vi) User Interface – The UI is a Windows Forms application built with the .NET
6 technology and comprises the graphical environment for the system’s
functionality, monitoring and maintenance. It can be installed on every computer
that can be connected to the same network as the wireless devices and each
software installation can be linked to a single panel to expedite the monitoring of
larger installation sites.
- The UI has multiple-user capabilities.
- It facilitates the user’s interaction with all of the devices within the network.
- It utilizes multiple selection criteria for filtering the search results of all
connected devices.
- It enables the user to export any available screen as an HTML format file for
future viewing and print any screen’s contents.
- The floor plan files can be exported as various image formats.
- The software is translated into seven (7) different languages.
1.2. System Requirements
The minimum system requirements are:
- Windows 10/11 x64
- 8GB RAM, or more
- 10GB of free storage, or more
- .NET Framework 4.8
- Internet connection

8
1.3. Topology
The wireless connection among the devices is established through a fast, mesh-
type network, at 868 MHz. A wireless network consists of a wireless network
master – gateway – and a group of wireless devices – luminaires, network
extenders and wireless input/output units – connected to the gateway, the master
device of the network.
Each wireless device can be connected directly to the gateway or use other
wireless devices that essentially serve as repeaters to reach the gateway, as per
the mesh-type network.
The previous image serves as a network formation example, of a mesh-type
network. The wireless range in a building’s interior is approximately 20 to 25
meters from device to device, when the in-between physical obstacles are typical
brick walls and wooden or synthetic furniture.
Multiple wireless networks can co-exist in an installation simultaneously and be
monitored through a single control panel. Each system can support up to 16
gateways and up to 200 wireless devices per gateway.

9
1.4. Wireless Network Specifications & Terms
(i) Wireless network master – The gateway is the master device of a wireless
network. A gateway’s role is to collect wireless data from the wireless emergency
lighting installation and transfer this data to the master control panel. Available
models include models with Ethernet/Wi-Fi, and USB connectivity.
(ii) Wireless device – Such a device may be any type of wireless device, i.e.,
emergency luminaires, network extenders and input/output units, that connect to
a wireless network.
(iii) UID (Unique ID) – UID is the unique address of each wireless device. It is
used by the central system to distinguish each wireless device from another. It
comes in 8-digit hexadecimal values.
(iv) SID (System ID) – SID represents the wireless network’s name. All wireless
devices within a wireless network must share the same SID to form a connection.
The default SID value is 00000001, in its 8-digit hexadecimal form.
(v) NKey (Network Key) – NKey is a key used to encrypt all transmitted
communications, providing a high security level, and preventing attacks on the
wireless network(s). The default NKey is set to 00000000, in its 8-digit
hexadecimal form.
(vi) RF Channel – This is the operating frequency of the wireless network. There
are four (4) available channels – numbered as 2, 3, 4 and 5 – within the 868.150
MHz – 868.450 MHz frequency range, to be used for the network(s), which can
be changed through the Installation menu of the software. When there are other
wireless networks operating nearby, a different RF channel should be used for
each network to avoid data traffic. The default channel is 2.
(vii) Hop level – The hopping functionality constitutes the primary feature of a
mesh-type network. Through this feature the wireless devices do not require to
be directly connected to a gateway, as data can be re-transmitted by any
wireless device located between the gateway and the target device, provided that
every in-between device is within the same network and in range. Thus, each
device in-between is also a repeater. The Hop level value indicates the number
of times the data hopped from one nearby device to another till it reached the
gateway. Typically, a wireless network is able to sustain up to 16 hops.
(viii) Network level – It is identical to the Hop level and indicates the number of
devices serving as repeaters between the gateway and a wireless device.
(ix) Self-healing – If a wireless device, e.g., a luminaire, which connects to a
gateway through hopping, loses its connection with its link, it will automatically
search for a new available route, if there is one, and reconnect. This function
does not require human interaction.

10
(x) Listen-before-talk – Prior to transmitting any data, a wireless device checks
the communication channel for occupancy in order to avoid any collisions and
data loss.
Note: In order for a gateway and a group of wireless devices to form a network
and connect to one another, they must share the same SID, Nkey and RF
Channel values.
When the SID and RF channel between two devices match, but the NKey values
do not, there will be a wireless connection where the transmitted data will not be
able to be decrypted, and thus no valid data will be received. When the SID or
the RF channel value between two devices differs, there will be no connection
between those two devices, as they will belong to different networks.
1.5. Wireless Network Installation & Restrictions
(i) If another wireless system operating at 868 MHz is present in the area, prior to
installation, the external Wireless Installation Tool application needs to be used
along with a GR-7605/V2 or GR-7607/V2 device to check the frequency
spectrum, through the same application, on channels 2, 3, 4 and 5. During
installation free channels are preferred over occupied RF channels, in order to
avoid collisions and data loss.
(ii) It is recommended to use a different RF channel for neighboring wireless
networks. An RF channel can be reused by two separate networks when their
closest devices are at least 80 meters away. When the distances between two
networks are shorter, a different RF channel should be used.
The distance can vary depending on the structure of the building.
(iii) During the installation of a wireless network, it is recommended that the GR-
7605/V2 Wireless Signal Strength Tester – RSSI – be used to check the signal
reception levels before installing and activating a wireless device, such as a
luminaire, at that position. The installation area that is closest to the gateway
should be measured first, persisting for at least 1 minute for better measurement
results. The observation of level indications of 3 and above is recommended. The
same should be repeated for each of the next installation areas. It should be

11
noted that each signal reading originates from any active and re-transmitting
wireless device. In cases where the signal is lower than level 3 and another
emergency luminaire cannot be installed in-between, the installation of a wireless
network extender should be considered.
(iv) The wireless signal is capable of traveling through the interior brick walls and
conventional furniture – wooden or synthetic – covering distances of 20 to 25
meters within the building’s interior. Building floors are usually made of reinforced
concrete with steel/iron bars that can interfere with the passing of the signal.
Therefore, when the installation area requires the coverage of multiple floors, it is
recommended that an independent wireless network be used for every floor. All
gateways can be connected to a local network and monitored from a single
control panel.
(v) The same wireless network to cover multiple buildings should be avoided,
even when the number of wireless devices has not reached the gateway’s limit of
200 devices. Attempting to cover multiple buildings with a single network may
lead to connection instability, due to weather conditions or outside obstacles.
Thus, an independent network should be created for every building, which can be
controlled via the same control panel, provided that there is a single local area
network that can be shared among the buildings.
(vi) Gateways are recommended to be installed at central points, where there is
at least 1 wireless device, such as a luminaire, within range and that is directly

12
connected to a gateway for every 15 wireless devices. For example, for a
network of one hundred and 120 wireless devices in total, at least 8 of them
should be directly connected to the gateway, within a 25-meter radius, in every
direction. Thus, a formation closely resembles the star formation is achieved and
the overall data load is split more efficiently.
(vii) The gateway’s device limit of 200 should not be exceeded. For maximum
capacity to be achieved, the previous rule must apply. Therefore, the gateway
should be installed at a position where at least 12 or 13 wireless devices are in
range to be directly connected to the gateway, spreading towards each direction.
(viii) During the technical study and prior to the installation, it is recommended
that alternative routes for most of the wireless devices be predicted and created,
to ensure proper communication, even in the event of a wireless link of a device
with the other devices breaking. In-line connections should be avoided whenever
possible because they do not provide alternative routes for the signal to pass
through when a link is broken.

15
1.7. Wireless Devices Installation
Each wireless device comes with the factory default values for the SID, Nkey and
RF channel of 00000001, 00000000, 2,respectively. In order for a device to join
a wireless network, the SID, Nkey and RF channel values must match those of
the network.
Before starting the installation process, it is recommended that at least 1 GR-
7605/V2 Wireless Signal Strength Tester RSSI T2 be available with a fully
charged battery. While it is plugged into a USB port for charging, the orange LED
– CHA will remain lit as long as it is still in charging mode. When the battery is
full, this LED will be turned off.
The step-by-step guide that follows is optional, but also the safest way to ensure
that the quality of the connection among the wireless devices is adequate and
stable.
(i) The gateway must be installed at its given location and activated. Chapter
3.1.6.1. should be referred to for further instructions on the installation or addition
of a gateway device to the system.
(ii) Once the gateway is active, it will start transmitting. The transmitted signal is
picked up by other wireless devices in order to detect and join a wireless
network. It can also be tracked by the Wireless Signal Strength Tester RSSI T2
that can read and display the received signal level – Received Signal Strength
Indication – with LED levels ranging from 1 through 5.
(iii) Once close to a position within 25 meters of the gateway, the Wireless Signal
Strength Tester RSSI T2 should be used to measure the signal. First, it should
be activated by pressing the main button for 3 seconds and then pushing it again
to change to the RSSI Tester indication mode. The red LED on the left will
immediately turn on. Within a few seconds, mode LEDs will be and remain turned
on so long as there is signal present at that position. After at least a full minute
passes, for better measurement results, the strength of the signal should have
been stabilized. If the indication level contains 3 or more turned on LEDs, then
the position is optimal for installing a wireless device and the quality of the
connection will be within the acceptable levels. Afterwards, the wireless device,
such as the luminaire, can be installed and activated. When the signal is weaker,
the addition of another wireless device in-between, such as a network extender
or another luminaire, should be considered to enhance the signal reception.

16
(iv) When installing a wireless device, it is advised that notes be taken regarding
the device’s location and UID address. The package-included extra UID stickers
can be used towards this end. This action will assist a potential graphical
installation plan later on.
(v) After installing and activating the first wireless devices, the same method can
be used to measure the signal’s strength at the following closest installation
position, and so on. It should be noted that every time a new device is activated,
the signal-level reading indicates the signal level that is received from the
gateway or any of the already installed wireless devices that operate as
repeaters. Similarly, the process may continue until the installation is completed.
(vi) By observing the LED indicators on the wireless adapters inside a luminaire,
it can be confirmed whether the device has joined the wireless network or not.
The blinking of both the LD2 and LD3 green LEDs indicates the successful
connection, while the blinking frequency indicates the connection’s quality. When
the LD3 LED is turned off, there is no connection. The corresponding manual
regarding the wireless adapter’s indication should be referred to.
(vii) When the installation of the wireless devices has been completed, a
graphical installation plan of the entire installation should be created, on paper or

17
via digital means. This step is important for any future installations, maintenance,
and troubleshooting. A sample image of a floor plan is displayed below.
The above image is only an example. A graphical floor plan may be created to
meet the needs of the installation.
(viii) When the installation is completed, along with a detailed graphical
installation plan, the networking of the wireless devices can commence, as
described in chapter 3.1.6.4.
This document’s layout contains chapters and sub-chapters that provide a
detailed account of the software’s installation and launch processes, a step-by-
step course through the home page’s functions and controls, and a detailed
treatment of each of the menu items and their respective sub-items, in the above
order.
Before starting
A very crucial step of the commissioning is to create proper documentation which
describes every aspect of the wireless emergency lighting installation, in such a way
that provides helpful information for later maintenance, replacements and
troubleshooting in general.
For each individual wireless network; write network parameters (SID / NKEY / RF
Channel), device location and models with matching UIDs, IP addresses for
Gateways and Master PC, etc. An example is depicted below:

18
There is not any specific form for this spreadsheet document. You may write
additional information or use a different formation, as long as the data are sufficient
for later maintenance, inspection, or modifications.
For the IPv4 network parameters it is recommended to use the same subnet for
Gateways and master PC. Consult an IT technician if needed. For the Gateway, the
IPv4 can be set as static or DHCP. For the master PC that runs the “Autronica GR-
7600/V2” application, the IPv4 always has to be static.

19
2. Software Installation
The installation process begins with the opening of the executable setup file.
When the file runs, it initializes a common setup wizard that guides the user
through the process.
By clicking Next, the user will be prompted to select the components they wish to
install. The default recommended option is the Full installation. All components
are necessary for the software’s complete functionality and first use. This
package includes the SQL server for which the user will be required to create an
account, all services that are needed to run the application, and the framework
on which all components will operate.

20
By clicking Next, the user will be given the option to create a desktop shortcut for
the application.
