Operating principle

00:00

00:14

LightSwitch Jeweller is a smart touch light switch. It controls the lighting in three ways: manually, through smartphone and PC apps, and using Automation Scenarios.

The device is installed without changing the electrical wiring of the object. The device does not require a neutral wire and works only from the supply phase.

The switch can control 5 to 600 W lighting devices. The kit includes a capacitor connected in parallel with the lighting device for low-power lamps. See the installation section of this manual for details.

LightSwitch frame has a LED backlight. The backlight is not bright, so it will not disturb users even if the device is installed near a bed. If necessary, a PRO or user with administrator rights can disable the backlight in Ajax apps.

The product line of devices includes 1­gang, 2­gang, and 2­way light switches: 1­gang — control one lighting line (one lamp). 2­gang — control two lighting lines (two lamps). 2­way — control one light source from several seats.
If necessary, LightSwitch can also control other devices. For example, one of the buttons can control the light, and the other one — room ventilation.
Manual control
LightSwitch allows controlling lighting when a hand is 15 millimetres away from the switch or when touching the touch-sensitive panel of the switch. Contactless control does not limit the possibility of use, even if hands are dirty or wet. The

sensor reacts under any conditions. Therefore, the switch can be installed in crowded places: restaurants, factories, and o ces. The LightSwitch sensor instantly reads the signal and transforms it into an electric pulse. LightCore receives this pulse and activates a relay that switches on/off the lighting device or another connected load, such as a cooker hood. The entire LightSwitch panel is touch sensitive. Therefore, the lighting can be controlled by pressing or reaching any part of the touch-sensitive panel with a hand.
Remote control
Control via the app LightSwitch can be used to control lighting manually and remotely through Ajax apps.
Press the switch in the LightSwitch eld in the Devices menu in the Ajax app, and the state of the switch contacts will change to the opposite; lighting will be switched off or on. This way, system users can remotely control the lighting. For example, switch on the light in the room in advance before entering the room.

The lighting also can be controlled in the Control menu. To do this, go to the Control menu and swipe up. All control devices added to the hub will appear in the list. Click on the switch in the LightSwitch eld, and the state of the device’s contacts will change to the opposite. The lighting will switch on or off.
Automation scenarios

00:00

00:07

Scenarios help automate security and reduce the number of routine actions. For example, set the lights to switch on by the schedule or when disarming the security system.

LightSwitch supports the following types of scenarios:
By alarm. By arming/disarming. By schedule. By Button pressing. By temperature. By humidity. By CO2 concentration. By LightSwitch pressing.
Scenarios by humidity and CO2 concentration are available when LifeQuality is added to the system.
More about scenarios
Operation modes
LightSwitch can operate in one of two modes: bistable or pulse. The operating mode is set by a user with admin or PRO rights in Ajax apps in the device settings. By default, LightSwitch works in bistable mode. When controlling the lighting, it switches on or off. When working in pulse mode, the lighting can be switched on for the required time: from 10 seconds to 2 hours. This mode is useful, for example, if a user needs to switch on the lighting in the corridor for 5 minutes when disarming the security system.
Types of electrical protection of the switch

LightSwitch has two independent types of protection: current and temperature.
Current protection is activated if the load current on the switch is 2.6 A or more. If the protection triggers, LightSwitch switches off power and sends a noti cation to Ajax apps. At the same time, the switch itself begins to ash red every second.
The power supply is not automatically restored when this protection is triggered. It can be reset by clicking on the toggle in the Ajax app or on the touch panel of the switch.
Temperature protection triggers if the temperature of the switch is greater than +60°C. If this protection triggers, LightSwitch turns off power and sends a noti cation to Ajax apps. The power supply resumes automatically when the switch temperature returns to normal.
Detection of lighting devices with insu cient power

LightSwitch regularly measures the switching current. If LightSwitch controls the power of a lighting device with insu cient power (up to 5 W), the system will notify the users of the Ajax system. In this case, it is necessary to replace the lighting device with a similar one with higher capacity or to connect a bundled capacitor in parallel with the lighting device.
Jeweller data transfer protocol
Jeweller is a radio protocol for fast and reliable two-way communication between a hub and connected devices. The protocol provides a range of wireless radio communication between LightSwitch and the hub (or range extender) up to 1,100 meters. This communication range allows installing switches not only in ats or private houses but also in open spaces or large warehouses.
Jeweller is responsible for transmitting all the necessary information and providing instant control of any number of LightSwitch devices in the system. Thanks to Jeweller, users can always control the light and see the current state of switches in Ajax apps at any time.
Jeweller supports block encryption with a oating key and authentication of devices at each communication session to prevent sabotage or device spoo ng. The protocol involves regular polling of system devices by the hub at intervals of 12 to 300 seconds (depending on the Jeweller or Jeweller/Fibra settings) to monitor communication with all devices and shows their statuses in the Ajax apps.
More about Jeweller

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.
Which CMSs are compatible with the Ajax security system
Only events of lost connection between the switch and the hub (or range extender) are transmitted to the CMS. No other events are sent to third-party monitoring stations of security or monitoring companies. Use PRO Desktop to receive all switch events on the CMS.
Temperature or current protection triggering events are not sent to PRO Desktop as alarms.
The addressability of Ajax devices allows sending to PRO Desktop or to CMS not only events but also the type of the device, its assigned name, security group, and room. The list of transmitted parameters may vary depending on the selected communication protocol with the CMS. The largest amount of information is transmitted to the PRO Desktop CMS.
The switch ID and loop (zone) number can be found in their states in the Ajax app.
Selecting the installation site

LightSwitch is designed to t into standard sub-sockets of the European form factor (55). The device should be connected to the power phase cable for proper operation. Connecting the zero power cable is not required.
Do not connect the zero power cable to LightSwtich. This can damage the device.
When installing LightSwitch, consider the Jeweller signal strength. It is determined by the ratio of the number of undelivered or corrupted data packages to those expected that are exchanged between the switch and the hub or range extender over a certain period.
The signal strength is indicated by the icon in the Devices menu. The signal strength is also indicated in the switch states.
Signal strength value:
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 signal strength at the installation site. The switch should have a signal strength of two or three bars. To roughly calculate the signal strength at the place of installation, use a radio communication range calculator.
With a signal strength of one or zero bars, the stable operation of the switch is not guaranteed. Use the radio signal range extender if the selected installation site has a signal strength of fewer than two bars.
Do not install the switch
Outdoors. The device has an IP20 protection class. This may result in device failure or incorrect operation.
On metal structures. This can lead to incorrect operation of the sensor: it may not respond to pressing or give false triggerings.
In rooms with humidity and temperature that are outside the permissible limits. Doing so may cause the device to malfunction or not work properly. The operating temperature range is from ­10 to +40°C. The permissible humidity is up to 75% without condensation.
In places with low or unstable signal strength. This may result in a loss of communication between the hub (or range extender) and the switch.
Installation

Only a quali ed electrician or installer should install LightSwitch. Do not switch on power at the switches before installing the touch-sensitive panels. Also, do not try to register the device before installing the touch-sensitive panel, as it contains antennas necessary for communication with the hub.
Before installing the switch, ensure that the optimal location has been selected and that it complies with the requirements of this manual. When installing and operating the device, follow the general electrical safety rules for using electrical appliances and the requirements of electrical safety regulations. For connection, use cables with a cross-section recommended by the manufacturer of the lighting device. LightSwitch cannot be connected to electric circuits with a load exceeding 600 W. The device does not require a neutral wire and works only from the supply phase. After installing and connecting the switch, be sure to run the Jeweller signal strength test and check the operation of the device: how it responds to touch, and whether it switches on/off the lights.
The installed touch-sensitive panel can be removed from LightSwitch with a at screwdriver. To complete this, insert it into the hole from below and turn the screwdriver.

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 switch to the app. Set the required settings
and create at least one virtual room. 4. Make sure that the hub is on and has Internet access via Ethernet, Wi-Fi,
and/or mobile network. This can be done in the Ajax app or by looking at the LED indicator of the hub: it should light up white or green. 5. Make sure the hub is not updated and not disarmed by checking its status of the Ajax app.
A PRO or user with admin rights can connect LightSwitch to the hub.
Connecting to the hub
Do not switch on power at the switches before installing the touch-sensitive panels. Also, do not try to register the device before installing the touch- sensitive panel, as it contains antennas necessary for communication with the hub.

LightSwitch should be within the coverage area of the hub’s radio network to connect to the hub. To work via the radio signal range extender, connect the LightSwitch with the hub and then connect the device to the range extender. This can be done in the range extender settings. The detailed instructions can be found in the manual for the relevant range extender.
The hub and the switch operating at different frequencies are incompatible. The radio frequency range of the device may vary by region. We recommend buying and using Ajax devices in the same region. Please contact Technical Support for information on the operating frequency range.
LightSwitch only works with one hub. When connected to a new hub, the switch stops sending commands to the old one. When added to a new hub, the switch is not removed from the device list of the old hub. This must be done through the Ajax app.
To connect LightSwitch to the hub:
1. Install LightSwitch if you haven’t done so before.
2. Open the Ajax app.
3. Select the hub if you have several of them or using the Ajax PRO app.
4. Go to the Devices tab and click Add device.
5. Enter the name of the device.
6. Scan the QR code of the device or enter the ID manually. QR code is located on the rear panel of LightCore, the front panel of LightCore, and the device packaging. The device ID can be found below the QR code.
7. Select the virtual room and security group (if the group mode is enabled).
8. Click Add — the countdown will begin.
If the maximum number of devices is added to the hub, when you try to add the switch in the Ajax app, you will get a noti cation about exceeding the device limit. The number of devices that can be connected to the hub depends on the central unit model and the Jeweller (or Jeweller/Fibra) settings.

9. In a few seconds, LightSwitch will appear in the list of hub devices. Refreshing the device statuses in the list depends on the Jeweller (or Jeweller/Fibra) settings. The default value is 36 seconds.
If the connection fails, try again in 5 seconds. But this time, during the countdown, press and hold the switch button for at least 3 seconds. If adding a 2-gang switch, press either button.
Functionality testing
After installation, test the operation of the switch: how it reacts to touch and whether it switches on/off the light.
Ajax security system provides several tests to select the location of devices correctly. Tests do not start immediately. However, the waiting time does not exceed the duration of one “hub–device” ping interval. The default value is 36 seconds. The device ping interval can be changed in the Jeweller (or Jeweller/Fibra) menu in the hub settings.
The Jeweller signal strength test is available for LightSwitch. The test allows for determining the strength and stability of the signal at the installation site.
To run a test in the Ajax app:
1. Select the hub if you have several of them or using a PRO app. 2. Go to the Devices tab. 3. Select LightSwitch. 4. Go to Settings . 5. Select Jeweller Signal Strength Test. 6. Run and perform the test using the prompts in the app.

LightSwitch has a backlight that makes the switch visible in the dark. If the frame of the device is backlit, the light is off. When the light is on, the frame is not backlit. The backlight is not bright, so it will not disturb users even if the device is installed near a bed. The backlight can be turned off in the Ajax app if necessary. If the temperature or current protection of LightSwitch has been triggered, or the touch-sensitive panel removed, the switch ashes red every second.
Malfunctions

When a device identi es a fault (for example, there is no connection with the hub), the Ajax app displays a fault counter in the device eld. All malfunctions are shown in switch states. Fields with malfunctions will be highlighted in red. A malfunction is displayed if:
Current protection was activated. Temperature protection was activated. A device with insu cient power is connected. An insu cient power supply is detected. There is no connection between LightSwitch and the hub (or range extender).
What to do in case of connection loss with the device
LightSwitch may lose connection with the hub for the following reasons: Power is no longer supplied.

The touch-sensitive panel has been removed (it has antennas on it, which are necessary for communication with the hub or range extender). The lighting device is faulty (for example, the incandescent lamp burned out). A device with insu cient power (up to 5 W) is connected. LightSwitch malfunction.
If an event is received about the loss of communication with the switch, the installer should check:
1. Power supplied on LightSwitch. 2. The presence of a touch-sensitive panel on the switch. 3. The operability of the lighting device.
If LightSwitch controls a lighting device with insu cient power (up to 5 W), it is necessary to replace the lighting device with a similar one with a higher power or connect a bundled capacitor in parallel with the lighting device.
Maintenance
Check the functioning of the switch regularly. 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, petrol, and other active solvents to clean the device.
