LifeQuality Jeweller User manual

Updated

LifeQuality Jeweller is a wireless air quality detector. Measures temperature, humidity, and CO2 (carbon dioxide) concentration in the room. Reports air pollution using an LED indicator and notifications in Ajax apps.

A hub is required for the detector to operate. The list of compatible hubs and range extenders is available here.

LifeQuality operates as part of the Ajax security system, communicating with the hub over two secure radio protocols: Jeweller and Wings: the detector uses Jeweller to transmit measurements, while Wings transmits data backups. The hub communication range is up to 1,700 meters without obstacles.

Functional elements

  1. LED indicator with a touch button. Reports the air quality and other detector events.
  2. SmartBracket mounting panel. To remove the panel, turn it counterclockwise.
  3. Power button.
  4. Device QR code and ID (serial number). It is used to connect the device to Ajax security system.

Operating principle

LifeQuality Jeweller is a wireless air quality detector. The detector monitors the temperature, humidity, and CO2 (carbon dioxide) concentration, measuring them once a minute.

LifeQuality measurements are available in Ajax apps in the Devices tab. A PRO or a user with system configuration rights can set up comfort thresholds of temperature, humidity, and CO2 (carbon dioxide). When values go beyond the specified limits, hub users receive notifications pointing out which indicator is outside the norm. This allows you to create an optimal microclimate in the room, reacting in time to the detector measurements.

Ajax automation devices respond to changes in LifeQuality indicators and perform user-defined actions using automation scenarios. For example, WallSwitch turns on the heating system when the specified minimum temperature is reached. Using LifeQuality with Ajax automation devices, supply systems, humidifiers, and air conditioning, it’s easy to maintain a comfortable microclimate inside.

Temperature and humidity sensor

Temperature and humidity are measured using a built-in combined SHT40 detector with digital sensors from the Swiss manufacturer Sensirion. The detector is installed in an isolated part of the main board. This excludes the influence of other board components and ensures measurement accuracy: the temperature measurement accuracy is ±0.2°C, and humidity is ±1.8%.

LifeQuality provides more accurate temperature measurements than other Ajax devices. Therefore, if the system includes LifeQuality, the Rooms tab in Ajax apps displays only the temperature measured by LifeQuality. The temperature measurements of other devices are ignored. Microclimate measurements will only consider data from other LifeQuality devices added to the room.

CO2 sensor

CO2 concentration is measured using a built-in Sunrise non-dispersive infrared (NDIR) detector from the Swedish manufacturer Senseair. This detector type is protected from measurement errors that may occur due to aerosols, perfumes or vapour of other substances.

The operating principle of the detector is based on detecting changes in the intensity of infrared radiation. Air naturally enters the detector chamber, through which the infrared lamp transmits radiation. The chamber walls allow the infrared beam to reflect and migrate to the infrared sensor, which absorbs radiation. With a special coating technology inside the chamber, the measurement accuracy is ± (30 + 3%) ppm.

In the migration process through the chamber, the radiation intensity changes due to the absorption of radiation part by carbon dioxide molecules. When the radiation reaches the endpoint and absorbs by the infrared sensor, the detector accurately detects CO2 concentration in the air.

Data storage

The detector measures temperature, humidity level and CO2 concentration once every minute. In Ajax apps, users can view current LifeQuality measurements and their history. The history of measurements is presented by charts. Charts show the trend of the selected air quality value over the last hour, day, week, month, or year. Ajax security system stores this data on the Ajax Cloud server for up to 2 years.

LifeQuality also has built-in memory that allows the detector to store measurements for up to 72 hours if communication with the hub or radio signal range extender is lost. As soon as the connection is restored, all values are sent to Ajax apps and synchronized with the charts.

Calibration

LifeQuality features automatic calibration of the CO2 sensor. This feature allows the sensor continuously transmit the most accurate measurements of the carbon dioxide concentration in the room. At the same time, the temperature and humidity sensor is calibrated at the production stage and does not require additional calibration.

The built-in CO2 sensor is calibrated every 1–14 days without user or installer interaction. LifeQuality automatically selects a calibration period based on the air conditions in the room. If the detector is used in an unventilated space, it should be manually calibrated every two to three weeks. You can run the calibration manually in Ajax apps.

Jeweller and Wings data transfer protocols

Jeweller and Wings are two-way wireless protocols for fast and reliable two-sided connection between the hub and connected devices. Jeweller technology is used to transmit events and measured values. If connection is lost, Wings allows you to send data backups from the detector to the hub when connection is restored.

The protocols support floating key block encryption and device recognition on every session to prevent sabotage and spoofing.

To monitor connection with system devices and display their statuses Ajax apps have a system of hub–detector polls with a frequency of 12 to 300 seconds. The polling frequency is set by a PRO or a user with system setup rights in the hub settings.

Sending events to the monitoring station

The Ajax security system can transmit events and alarms to the PRO Desktop monitoring app as well as the Central Monitoring Station (CMS) via SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other protocols. The list of supported protocols is available here.

Only communication loss events between LifeQuality and the hub (or the radio signal range extender) are transmitted to the CMS. Use PRO Desktop to receive all smart air quality detector events.

Addressability of Ajax devices allows you to send not only events but also the type of the device, the name, virtual room, and security group assigned to it to the PRO Desktop and to the CMS. The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.

The ID and detector loop (zone) number are available in the detector States.

Adding to the system

Before adding a device

  1. Install the Ajax app.
  2. Create an account if you don’t have one.
  3. Add a hub compatible with the detector to your app. Set the necessary settings and create at least one virtual room.
  4. Make sure that the hub is turned on and has Internet access via Ethernet, Wi-Fi, and/or mobile network. You can do this in the Ajax app or by looking at the hub LED indicator: it lights up white or green.
  5. Make sure that the hub is disarmed and does not start updating by checking the status in the Ajax app.

Only a PRO or a user with system configuration rights can connect LifeQuality to the hub.

LifeQuality should be within the coverage area of the hub radio network. To operate via a radio signal range extender, connect LifeQuality to the hub first. Then connect the detector to the range extender in its settings.

How to add LifeQuality Jeweller to the hub

  1. Open the Ajax app.
  2. Select the hub if you have several of them or if you are using the PRO app.
  3. Go to the Devices tab. Click Add Device.
  4. Specify the name of the device.
  5. Scan the QR code or enter the ID manually. QR code is located on the enclosure and on the device packaging. The ID can be found under the QR code.
  6. Select a virtual room and security group (if group mode is enabled).
  7. Click Add.

    If the maximum number of devices is added to the hub, you will be notified about exceeding the hub limit. The number of devices connected to the hub depends on the hub model.

  8. Turn on LifeQuality by holding the power button for 3 seconds. The hub connection request is sent only if the detector is enabled. If the detector fails to connect to the hub, try again in 5 seconds.

    The detector cannot connect to the hub if they operate on different radio frequencies. The radio frequency range of the device may vary by region. Please contact technical support for information on the operating frequency range of your devices.

Once connected, LifeQuality will appear in the device list in the Ajax app. Device status update depends on the polling interval set in the Jeweller or Jeweller/Fibra settings. The default value is 36 seconds.

LifeQuality operates with one hub only. When connected to a new hub, the detector stops transmitting data to the old hub. Once added to a new hub, LifeQuality is not removed from the list of devices of the old hub. This must be done manually in Ajax apps.

Selecting the installation place

ajax lifequality

The device is for indoor use only.

LifeQuality can be mounted on a vertical surface using an included installation kit. The device can also be placed on any horizontal surface without mounting. We recommend mounting the device on a vertical surface. It will prevent the device from being displaced or accidentally dropped.

We recommend installing the detector at the height of a human airway. For example, locate it in the office at the sitting person’s head level or in the bedroom next to the bedhead. LifeQuality installs in every room in areas that are expected to be crowded. One detector operates effectively in one room, regardless of its size.

We recommend installing the detector in a ventilated room. If this is not possible, the CO2 sensor should be manually calibrated every two to three weeks.

When choosing the location of the detector, consider the parameters that affect its operation:

  • Jeweller signal strength.
  • Wings signal strength.
  • Distance between the detector and the hub.
  • Presence of barriers for radio signal passage between devices: walls, interfloor ceilings, large objects located in the room.

Consider the placement recommendations when designing your Ajax security system for the object. The security system must be designed and installed by specialists. The list of recommended Ajax partners is available here.

Signal strength

The Jeweller/Wings signal strength is determined by the ratio of the number of undelivered or corrupted data packets to expected ones that are exchanged between the hub and the detector within a certain period of time. Signal strength is indicated by the icon on the Devices tab:

  • Three bars — excellent signal strength.
  • Two bars — good signal strength.
  • One bar — low signal strength; stable operation is not guaranteed.
  • Crossed out icon — no signal; stable operation is not guaranteed.

Check the Jeweller and Wings signals strength at the installation place. We cannot guarantee stable operation if the signal strength is as low as one or zero bars. In this case, move the device. Repositioning even by 20 cm can significantly improve signal reception.

If the detector still has a low or unstable signal after it was moved, use ReX 2.

LifeQuality is not compatible with ReX. The list of compatible range extenders is available here.

Do not install the detector

  • Outdoors. This could damage the detector.
  • In places with fast air circulation. For example, near fans, open windows, or doors. This can lead to incorrect measurements.
  • Opposite any objects with rapidly changing temperature. For example, near electric and gas heaters. This can lead to incorrect temperature measurements.
  • In places where the detector has low or unstable signal strength. This can lead to a connection loss between the detector and the hub or radio signal range extender.
  • Inside premises with temperature and humidity outside the device’s operation limits. This could damage the detector.
  • In closed botanic gardens, greenhouses, and rooms with a large number of plants. The detector is not suitable for operation in such conditions.

Installation

Before installing LifeQuality, perform the manual calibration of the CO2 sensor.

How to run the CO2 sensor calibration manually

Make sure that you have selected the optimal location and that it complies with the requirements of this manual.

In order to install the detector:

  1. Remove the SmartBracket mounting panel from the detector. To remove the panel, turn it counterclockwise.
  2. Fix the SmartBracket panel to a vertical surface using double-sided adhesive tape or other temporary fastener. The mounting panel has an UP sign, which indicates the correct position of the panel.

    Use double-sided adhesive tape for temporary fixation only. The device fixed permanently with adhesive tape can peel off the surface at any time, leading to damage if the device is dropped.

  3. Run the Jeweller and Wings signal strength tests. The recommended value is two or three bars.

    If the signal strength is a single bar or lower, we cannot guarantee the stable operation of the system. Move the device as repositioning even by 20 cm can significantly improve the signal reception. If low or unstable signal strength is still reported after relocation, use the ReX 2 radio signal range extender.

  4. Remove the detector from the mount.
  5. Fasten the SmartBracket panel with bundled screws using all fixation points. If using other fasteners, ensure they do not damage or deform the mounting panel.
  6. Place the detector on the SmartBracket mounting panel.

Malfunctions

If malfunction is detected (for example, there is no connection with the hub or range extender), the Ajax app displays a malfunction counter in the device field.

Malfunctions are displayed in the detector States. Fields with malfunctions are highlighted in red.

The device can report malfunctions to the monitoring station of the security company, as well as to users through push notifications and SMS.

LifeQuality malfunctions

  • Temperature is outside the device’s operation limits.
  • Humidity is outside the device’s operation limits.
  • CO2 concentration exceeds the device’s range.
  • No connection to the hub or radio signal range extender.
  • The detector registered the fault of one or several built-in sensors.
  • The battery charge level is low.

Maintenance

Regularly check the functioning of the detector. The optimal frequency of check-ups is once every three months. Clean the enclosure from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care. Do not use substances that contain alcohol, acetone, gasoline, and other active solvents to clean the device.

If the detector is used in an unventilated space, it should be manually calibrated every two to three weeks. You can run the calibration manually in Ajax apps.
