LightSwitch (Dimmer) Jeweller user manual

Design

LightSwitch is a prefabricated smart light switch. All switch components are purchased separately. Elements are connected mechanically without the need for tools. There are two LightSwitch formats in the Ajax product line: single and combined. Combined switches can be horizontal and vertical.

Single switch

A single LightSwitch (Dimmer) Jeweller is a prefabricated device that consists of two components:

• LightCore (Dimmer) Jeweller — dimmer core.
• SoloButton (Dimmer) — touch-sensitive panel for a single LightSwitch (Dimmer) Jeweller.

Combined switch

A combined switch consists of several LightCore relays or LightCore (Dimmer) dimmer cores and touch-sensitive panels installed into one Frame with the appropriate number of seats.

Side touch-sensitive panels are installed on the right and left or on the top and bottom sides of the frame, while central touch-sensitive panels are installed in the center. For example, two side panels and one central panel should be used for three switches in one frame.

Colors

The product line includes 8 colors of touch-sensitive panels: White, Fog, Grey, Graphite, Ivory, Oyster, Olive, and Black.

The RAL colors below are as close as an approximation of the actual color. However, they may slightly differ, so please only use them as a guide to the color choice.

In the switch settings in Ajax apps, the color of LightSwitch can be changed. The color in the app does not have to match the color of the installed panel.

A PRO or a user with admin rights can change the panel color anytime. For example, if the installer has replaced the touch-sensitive panel or a user wishes to set different colors for the switches in the app to distinguish them.

Operating principle

LightSwitch (Dimmer) Jeweller is a smart touch light switch with an integrated dimming slider. It can control the lighting brightness in three ways: manually, through smartphone and PC apps, and using automation scenarios.

LightSwitch is installed without changing the electrical wiring at the facility. The device does not require a neutral wire and operates only from the power phase.

LightSwitch can be used without adding to a hub. In this mode, it operates like a regular touch switch.

LightSwitch (Dimmer) Jeweller can control lighting appliances with a power range of 8 to 150 VA. If, during the connection, the lamp compatible with LightSwitch (Dimmer) Jeweller flickers or the dimmer does not work, connect Bypass (Dimmer) [55]. The bypass is sold separately. Refer to the Installation section of this manual for more information.

The dimmer allows you to adjust the brightness of the lighting appliance remotely in Ajax apps or by pressing the touch-sensitive panel. To change the brightness, long press the dimming slider on the touch-sensitive panel. The zone of the dimmer corresponds to the brightness level: the higher the zone, the higher the brightness will be set on the lighting appliance. The brightness control is smooth, allowing you to adjust the desired brightness level. The set parameters are saved when the device is turned off and reproduced the next time it is turned on.

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

The product line includes one-gang and two-gang regular, two-way, and crossover light switches:

• LightSwitch (1-gang) Jeweller
• LightSwitch (2-gang) Jeweller
• LightSwitch (2-way) Jeweller
• LightSwitch (2-gang/2-way) Jeweller
• LightSwitch (Crossover) Jeweller

Devices combined in a frame can be installed horizontally and vertically. Vertical installation is supported only by switches, dimmers, touch-sensitive panels, and frames with the label “vertical” in the name.

Use the online Ajax switches and outlets configurator to assemble your custom set. Combine devices into a frame, pick the color, and download your configuration as PDF.

Remote control

Control via the app

LightSwitch can be used to control lighting manually and remotely through Ajax apps.

Open the Ajax app and click on the toggle in the LightSwitch field in the Devices menu: the lighting will be turned off/on. This way, system users can, for example, switch on the lights in the room in advance. Move the slider to change the brightness of the lighting appliance.

Lighting control is also available 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 field, and the lighting will be switched on/off. Long tap on the dimmer icon to change the brightness of the lighting appliance.

Automation scenarios

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

LightSwitch supports the following types of scenarios:

• By alarm
• By arming/disarming
• By schedule
• By pressing Button/Button S
• By temperature
• By humidity
• By CO₂ concentration
• By pressing another LightSwitch

Scenarios by humidity and CO₂ concentration are available when LifeQuality is added to the system.

The system does not allow creating sequences of scenarios when the execution of one scenario activates the following one. It prevents accidental endless looping of such scenarios.

Operation modes

LightSwitch can operate in one of two modes: bistable or pulse. The operating mode is set by a PRO or a user with admin rights in the device settings in Ajax apps.

By default, LightSwitch operates in bistable mode, which means the device switches on/off when controlling the lighting.

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 (Dimmer) Jeweller has two independent types of protection: current and temperature.

Overcurrent protection is provided by the fast-blow 3.15 A fuse installed inside the device. The device also has overcurrent protection at the software level: if the current exceeds 0.75 A, LightSwitch (Dimmer) Jeweller turns off the power and sends a notification to Ajax apps.

Temperature protection triggers if the temperature of the switch exceeds +60 °C. If this protection triggers, LightSwitch turns off the power and sends a notification to Ajax apps. The power supply is restored automatically when the temperature of the switch returns to normal.

Types of supported lamps

Information on LightSwitch operation with different types of lamps is provided in the table.

If, during the connection, the lighting appliance compatible with LightSwitch (Dimmer) Jeweller flickers or the dimmer does not work, raise the minimum brightness threshold in the device settings. Connect Bypass (Dimmer) [55] that is sold separately.

Jeweller and Wings data transfer protocols

Jeweller and Wings are wireless data transfer protocols that provide two-way fast and reliable communication between the hub and devices. The light switch uses Jeweller to transmit alarms and events, and Wings to update the firmware.

Firmware update

If a new firmware version for LightSwitch (Dimmer) Jeweller is available, the icon appears in Ajax apps in the Devices tab. You can launch the update in states or via the light switch settings. Follow the on-screen instructions to successfully update the firmware.

Information on firmware updates and new versions is available only for light switches that use the ReX 2 radio signal range extender and/or are added to such control panels:

• Hub 2 (2G);
• Hub 2 (4G);
• Hub 2 Plus;
• Hub Hybrid (2G);
• Hub Hybrid (4G).

Users will receive information about the new firmware version if the light switch is connected to the hub via ReX. However, the update is possible only after adding the light switch directly to the above control panels.

Firmware updates are not available for LightSwitch when operating via Hub Plus.

Sending events to the monitoring station

The Ajax system can transmit alarms to both PRO Desktop monitoring app and the central monitoring station (CMS) in the formats of SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.

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 protection triggering events are not sent to PRO Desktop as alarms.

When an alarm is received, the operator at the security company’s CMS knows what happened and precisely where to dispatch a rapid response team. The addressability of Ajax devices allows sending events to PRO Desktop or the CMS, including the device type, its name, security group, and virtual room. Note that the list of transmitted parameters may vary depending on the CMS type and the selected communication protocol for it.

The ID and number of the device can be found in its states in the Ajax app.

Selecting the installation site

LightSwitch (Dimmer) Jeweller is designed to fit into standard sub-sockets of the European form factor (55). The device should be connected to the power phase wire for proper operation. Connecting the neutral wire is not required.

Do not connect the neutral wire to the LightSwitch (Dimmer) Jeweller terminals. This can damage the device.

Signal strength

The Jeweller and Wings signal strength is determined by the number of undelivered or corrupted data packages over a certain period of time. The icon on the Devices tab indicates the signal strength:

• 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.

Check the Jeweller and Wings signal strength before the final installation. With a signal strength of one or zero bars, we do not guarantee stable operation of the device. Consider relocating the device, as adjusting its position even by 20 cm can significantly improve the signal strength. If the signal remains poor or unstable after relocation, consider using ReX Jeweller or ReX 2 Jeweller radio signal range extender.

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 touch or give false triggerings.
• In rooms with humidity and temperature that are outside the permissible limits. This may cause a malfunction or incorrect operation of the device. 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 qualified electrician or installer should install LightSwitch (Dimmer) Jeweller. Do not turn on the 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 needed to communicate with the hub.

Before installing the dimmer, 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 (Dimmer) Jeweller cannot be connected to electric circuits with a load exceeding 150 VA. 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 functionality testing, 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 flat screwdriver. To complete this, insert it into the hole from below (or from the left for vertical switches) and turn the screwdriver.

LightSwitch (Dimmer) Jeweller can control lighting appliances of 8 to 150 VA. If, during the connection, the lamp compatible with LightSwitch (Dimmer) Jeweller flickers or the dimmer does not work, connect Bypass (Dimmer) [55]. The bypass is sold separately.

Adding to the system

Before adding a device

1. Install the Ajax app.
2. Log in to your account or create a new one.
3. Select a space or create a new one.
   What is a space
   How to create a space
   

   The space functionality is available for apps of such versions or later:

   • Ajax Security System 3.0 for iOS;
   • Ajax Security System 3.0 for Android;
   • Ajax PRO: Tool for Engineers 2.0 for iOS;
   • Ajax PRO: Tool for Engineers 2.0 for Android;
   • Ajax PRO Desktop 4.0 for macOS;
   • Ajax PRO Desktop 4.0 for Windows.
4. Add at least one virtual room.
5. Add a compatible hub to the space. Ensure the hub is switched on and has internet access via Ethernet, Wi-Fi, and/or mobile network.
6. Ensure the space is disarmed, and the hub is not starting an update by checking statuses in the Ajax app.

Only a PRO or a space admin with the rights to configure the system can add a device to the hub.

Pairing with the hub

Power on the switch and register this device only when the touch-sensitive panel is installed. The panel contains antennas necessary for communication with the hub.

LightSwitch should be within the coverage area of the hub’s radio network to pair with the hub. To work via the radio signal range extender, pair LightSwitch with the hub and then add it to the range extender. This can be done in the range extender settings. 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 paired with a new hub, the switch stops sending commands to the old one. However, the device is not automatically removed from the device list of the old hub. This must be done manually in the Ajax app.

To add LightSwitch to the hub:

1. Install LightSwitch if you haven’t done so before.
2. Open the Ajax app and select the space where you want to add the device.
3. Go to the Devices tab and click Add Device.
4. Enter the name of the device.
5. 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.
6. Select a room and a group (if the group mode is enabled).
7. Click Add.
   

   If the maximum number of devices is added to the hub, you will get a notification about exceeding the device limit when you try to add the switch in the Ajax app. The number of devices that can be added to the hub depends on the control panel model and the Jeweller (or Jeweller/Fibra) settings.

8. In a few seconds, LightSwitch will appear in the list of hub devices. Updating the device states 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 you press and hold the button of LightSwitch not paired with the hub for at least 3 seconds, the switch flashes green every second for one minute to inform you that it is not paired with the hub.

Functionality testing

After installation, test the operation of the switch: how it responds to touch and whether it switches on/off the light.

The Ajax 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 and Wings Signal Strength Test are available for LightSwitch. The test allows to determine the strength and stability of the signal at the installation site.

To run a test in the Ajax app:

1. Select the required space.
2. Go to the Devices tab.
3. Select LightSwitch from the list.
4. Go to Settings .
5. Select a test:
   1. Jeweller signal strength test.
   2. Wings signal strength test.
6. Run and perform the test using the prompts in the app.

LED indication

LightSwitch has a backlight that makes the switch visible in the dark. If the lighting is off, the device frame is backlit; if the lighting 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 protection of LightSwitch has been triggered or the touch-sensitive panel removed, the switch flashes red every second.

To inform you that LightSwitch is not paired with the hub, it flashes green every second for one minute:

• when you connect LightSwitch to the power supply the first time;
• when you press and hold the LightSwitch button for at least 3 seconds.

Malfunctions

When the switch malfunction is detected (for example, there is no connection with the hub), the Ajax app displays a malfunction counter on the device icon.

All malfunctions are indicated in the switch states. Fields with malfunctions will be highlighted in red.

A malfunction is displayed if:

• Temperature protection was activated.
• An appliance with insufficient power is connected.
• An insufficient power supply is detected.
• There is no communication between LightSwitch and the hub (or range extender).

What to do in case of communication loss with the device

LightSwitch may lose communication 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 lighting appliance that is not supported by LightSwitch (Dimmer) Jeweller is connected. You can learn about the types of supported lamps here.
• LightSwitch (Dimmer) Jeweller malfunction.

If an event about the loss of communication with the switch is received, the installer should check:

1. Power supply of LightSwitch.
2. Presence of a touch-sensitive panel on the switch.
3. Operability of the lighting appliance.

What to do if the lighting appliance does not operate correctly

If the lighting appliance flickers or does not turn on when connected to LightSwitch (Dimmer) Jeweller:

• Check the compatibility of the lighting appliance connected to LightSwitch (Dimmer) Jeweller.
• Raise the brightness threshold in the dimmer settings.
• Connect the bypass. Bypass (Dimmer) [55] is sold separately.
• Change the lamp. Incorrect operation of the dimmer may be due to the characteristics of the lighting appliance.

If the problem is not resolved, the flickering of the lighting appliance may be caused by an unstable 230 V, 50 Hz power supply.

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.
