FAQs

• How can I mute the gas alarm?
  • If the gas Pre-Alarm or Alarm sounds, pressing once will mute the alarm tone (See parameter b03).
• How do I know if the device is connected to the NBIoT network?
  • The display will indicate if the device is connected to the NBIoT network (Narrowband). A switched-off display means it is not connected or the license has expired.

IMPORTANT SAFETY 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, to ensure compliance with standards on human exposure to electromagnetic fields.
• The AKO-575400NE device must NEVER be operating without having installed the external antenna. This device can be fitted with any antenna provided it has a gain of fewer than 9.2 dBi and there is a minimum distance of more than 20 cm between it and any person or animal.
• Any type of antenna used with this device must comply with the limits established for the radio interface in the Member States and the following documents: Commission Decision 2010/267/EU of 6 May 2010, ECC Decision (09)03 of 30 October 2009 and CEPT Report 30 of 30 October 2009.

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 vapors may generate false alarms.
• The sensor should be installed away from: -Smoke outlets located in confined spaces or from engines, generators, or motorized 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
• The gases currently used in industrial refrigeration, for which this transmitter has been designed, are heavier than air. They are therefore always concentrated in the lowest part of the refrigerated room or space. Please consider this when choosing the installation site. It is advisable to leave a distance of around 50 cm free.

WIRING

Power Supply To Do The Wiring

• Always disconnect the power supply to do the wiring.
• The wiring between the transmitter and the station must NEVER be installed in a conduit together with power, control or power supply cables.
• Cables for wiring the relay contacts should have an adequate section depending on the unit to be connected.
• Certain international standards maintain that the power supply of the alarm should originate from a different circuit to that used by the refrigeration and ventilation system. Please ensure that you comply with current local regulations.
• If connecting to a MODBUS network the double connection strips included must be used (see box)

Description

• Flashing: Malfunction in NBIoT module
• Constant: Connected to the NBIoT network (Narrowband)
• Switched off: NOT connected to the NBIoT network or expired license.
• 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 and 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.

Operation

Without alarms

• The display shows the current gas concentration in ppm.
• Parameter b02 allows you to fix a value below which the display will always show zero.
• 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.) is sent to the cloud instantly.

Alarms

• The transmitter emits an acoustic alarm, and the alarm indicator flashes and activates the relays when certain gas concentration levels are exceeded. If the transmitter is connected to a station, the station will emit an acoustic alarm. The relays will be activated on both devices.
• Two alarm levels are depending on the concentration of gas detected: Pre-Alarm and Alarm. Both are factory preset but can be modified employing parameters AL3 and AL6. These values comply with domestic and international regulations (RSIF, EN 378 and
• EN 14624). However, please ensure that these values comply with current local regulations. To modify these values, the parameter
• AL1 should be configured to 1.
• Activations and deactivations of pre-alarms and alarms are sent to the cloud instantly.

Default parameters

To set the device to factory default, switch off the power supply and switch it on again, and press the sequence and SET within 2 minutes.
The display shows the message dFp (default parameters) with a choice of two options:

• 0: Parameters are not modified
• 1: All parameters are reset to their default values.

Signing up toakonet.cloud

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:
