Life Quality Jeweller Temperature Humidity and CO2 Monitor

Life Quality 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, enables automation scenarios.

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 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.

Operating principle

Life Quality Jeweller is a wireless air quality detector. The detector monitors the temperature, humidity, and CO2 (carbon dioxide) concentration, measuring them once a minute.
Life Quality 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) concentration. 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 Life Quality indicators and perform user-deﬁned actions using automation scenarios. For example, Wall Switch turns on the heating system when the speciﬁed minimum temperature is reached. Using Life Quality 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%.

Life Quality provides more accurate temperature measurements than other Ajax devices. Therefore, if the system includes Life Quality, the Rooms tab in Ajax apps displays only the temperature measured by Life Quality. The temperature measurements of other devices are ignored. Microclimate measurements will only consider data from other Life Quality 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 is absorbed by the infrared sensor, the detector accurately detects CO2 concentration in the air.

Data storage

AJAX LifeQuality Jeweller Temperature Humidity and CO2 Monitor - Data
storage

The detector measures temperature, humidity level and CO2 concentration once every minute. In Ajax apps, users can view current Life Quality 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 system stores this data on the Ajax Cloud server for up to 2 years.

Life Quality 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.
How to view charts

Calibration

Life Quality 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 at the production stage and automatically every 15 days without user or installer interaction. The automatic calibration mode is effective for ventilated rooms where CO2 concentration is reduced to 400 ppm at least once every 15 days. If the detector is used in an unventilated space, we recommend calibrating it manually once a year. You can run the calibration manually in Ajax apps.

How to run the CO2 sensor calibration manually
The CO2 sensor calibration cannot be reset to the production or previous version. It takes effect as soon as the calibration process is completed. If it is interrupted, the device retains the result of the previous calibration.

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 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.

Which CMSs Ajax connects to

Only communication loss events between Life Quality 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

Install the Ajax app.
Create an account if you don’t have one.
Add a hub compatible with the detector to your app. Set the necessary settings and create at least one virtual room .
Make sure that the hub is turned on and has Internet access via Ethernet, WiFi, 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.
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 Life Quality to the hub.

Life Quality should be within the coverage area of the hub radio network. To operate via a radio signal range extender ReX 2, connect Life Quality to the hub ﬁrst. Then connect the detector to the range extender in its settings.

Note that Life Quality does not work with the ReX radio signal range extender.

How to add Life Quality Jeweller to the hub

Open the Ajax app.
Select the hub if you have several of them or if you are using the PRO app.
Go to the Devices tab. Click Add Device.
Specify the name of the device.
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.
Select a virtual room and security group (if group mode is enabled).
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.
Turn on Life Quality 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, Life Quality 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.
Life Quality 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, Life Quality is not removed from the list of devices of the old hub. This must be done manually in Ajax apps.

The CO2 sensor is calibrated for up to 20 minutes. After clicking the Start button, the timer in the app will start the countdown. Calibration ends automatically after the countdown is completed — return Life Quality to the selected installation place.

Selecting the installation place

AJAX LifeQuality Jeweller Temperature Humidity and CO2 Monitor - Selecting
the installation place

The device is for indoor use only.

Life Quality can be mounted on a vertical surface using an included installation kit.
The device can also be placed on a horizontal surface without mounting. We recommend mounting the device on a vertical surface or on a ceiling. 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. Life Quality installs in every room in areas that are expected to be crowded. One detector operates effectively in one room, regardless of its size.
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, inter ﬂoor ceilings, large objects located in the room.

Consider the placement recommendations when designing your Ajax 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.

Life Quality 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

Remove the Smart Bracket mounting panel from the detector. To remove the panel, turn it counterclockwise.
Fix the Smart Bracket 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.
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.
Remove the detector from the mount.
Fasten the Smart Bracket panel with bundled screws using all ﬁxation points.
If using other fasteners, ensure they do not damage or deform the mounting panel.
Place the detector on the Smart Bracket 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.
