We reserve the right to supply materials that might vary slightly to those described in
our Technical Sheets. Updated information is available on our website.
Warning
-Transmitters / detectors should be installed in a place protected from vibrations, water and corrosive gases, where the ambient temperature does not exceed the value indicated in the technical data.
-The transmitters / detectors are not suitable for areas classified as potentially explosive.
-Transmitters/detectors supervise a point and not an area. If the gas leak does not reach the sensor, or the level of concentration in that point does not reach the foreseen values
according to the type of gas no alarm will be activated. If perimeter supervision is required, several sensors should be installed around that area.
-Avoid installing the device on metal walls or near devices that may produce radio emissions.
-This device must be installed in a location where a minimum distance of 20 cm to the human body can be guaranteed, in order to ensure compliance with standards on human exposure to electromagnetic fields.
Working conditions:
-Avoid handling refrigerant gases near the sensor. If this is unavoidable, use Set Hold or Maintenance mode. Do not paint the sensor or place it near solvents or paints. Exposure to acetone vapours may
generate false alarms.
-The sensor should be installed away from: -Smoke outlets located in confined spaces or from engines, generators or motorised machinery (fork-lift trucks, etc.).
-Particularly damp areas or areas with strong ventilation.
-The detector should usually be installed in an area where gas may concentrate, near places where gas leaks could start
-CO is heavier than air. Therefore, it always concentrates in the lowest part of the refrigerated room or space. Please take this into consideration when choosing the installation site. It is advisable to leave a
2
distance of around 50 cm free.

Gas sensor
Keyboard
Display Constant: NBIoT module in operation
Flashing: Malfunction in NBIoT module
Constant: Connected to the NBIoT network (Narrow band)
Switched off: NOT connected to the NBIoT network or expired license.
+Forces data transfer to the cloud via NBIoT connectivity.
If the gas Pre-Alarm or Alarm sounds, pressing once will mute the alarm tone (See parameter b03).
In the programming menu, it exits the parameter without saving changes, returns to previous
level or exits programming.
Pressing for 3 seconds activates or deactivates Set Hold mode.
Pressing for 6 seconds activates or deactivates maintenance mode.
In the programming menu it allows scrolling around the different levels, or during the setting of
a parameter, changing its value.
Fixed: Gas pre-alarm activated.
Flashing: Gas alarm activated.
Fixed: Set Hold mode activated
Flashing: Maintenance mode activated
The display shows the type of gas detected. The display shows the current gas concentration in ppm (parts per million).
The value displayed should be multiplied by 10.
Gas alarm on mute
Unit in programming mode.
Pressing once (< 1 second) will show the type of gas detected, the date and time in
sequential order.
Pressing for 3 seconds displays the Pre-Alarm and Alarm levels that have been configured.
In the programming menu it allows scrolling around the different levels, or during the
setting of a parameter, changing its value.
Pressing for 3 seconds accesses the configuration of alarm and pre-alarm levels.
Pressing it for 6 seconds accesses the advanced programming menu.
In the programming menu, it accesses the level shown on the display or, during the
setting of a parameter, accepts the new value.

Signing up to akonet.cloud
In order for the transmitter to be able to send operating data to akonet.cloud, it must be registered. To do this, go to
https://akonet.cloud (requires registration), click on “Add new device” and continue with one of these two methods:MAS
A.-Enter the serial number (S/N) and validation code / IMEI that appear on the tag and press “Search”.
B.-Capture the QR code that appears on the tag using the option (requires having a camera on your PC, tablet or QRC
mobile phone).
These data are found on the tag on the right hand side of the transmitter.
More information can be found in the akonet.cloud user guide at:
”http://help.ako.com/manuales/akonet-cloud”
To access akonet.cloud, enter this address in your browser (the use of Google Chrome is recommended):
https://akonet.cloud.
Before activating the device, make sure that there is enough reception at the installation location. Activated
devices may not be returned.
Forcing transmission
When the steps of the configuration wizard and the registration process are completed in akonet.cloud, you must force a
first transmission to verify the level of reception:
ŸPress and hold the ESC and SET keys for 3 seconds.
ŸAfter a moment, the display shows the quality of the NBIoT signal received:
The transmitter does not start transmitting data to akonet.cloud until the first transmission is forced.
Operation
Without alarms
The display shows the current gas concentration in ppm.
The transmitter regularly sends to the cloud (akonet.cloud) the gas concentration data and other operation information at specific intervals based on the akonet.cloud
parameter “continual log interval”.
Any change in the configuration of the transmitter or its operation (mode changes, errors, etc.) are sent to the cloud instantly.
Alarms
The transmitter emits an acoustic alarm, the alarm indicator flashes and activates the relays when certain gas concentration levels are exceeded.
There are two alarm levels depending on the concentration of gas detected: Pre-Alarm and Alarm. These have a factory setting of 1000 and 1400 PPM respectively. These
values comply with domestic and international regulations. However, please ensure that these values comply with current local regulations. In order to modify these values,
parameter AL1 should be configured to 1.
Activations and deactivations of pre-alarms and alarms are sent to the cloud instantly.
There are two possible methods for modifying the transmitter’s configuration:
-Through the device’s programming menu (refer to the user manual available at www.ako.com).
-At www.akonet.cloud, by accessing the device parameters menu.
