📘 WallSwitch User manual

WallSwitch is a device combining a wireless power on and off the relay for electrical appliances with the capacity up to 3 kW, as well as a power consumption detector. The miniature body of the device is adapted for installation in a European socket box.

⚠️ WallSwitch should be only installed by a qualified electrician! Regardless of the type of the electrical circuit in which the device is installed.

WallSwitch operates only with the Ajax security system (it may not be used in any third-party security systems), by connecting via the protected Jeweller protocol to the Hub. Communication range - up to 1,000 meters, absent any obstacles.

The WallSwitch only operates with Hub. Connection to ocBridge and uartBridge integration modules is not provided.

The Ajax security system is self-sustaining, but the user can connect it to the central monitoring station of a private security company.

Functional Elements

  1. Antenna
  2. Terminal blocks
  3. Functional button
  4. Light indicator

IN terminals:

  • L terminal — power supply phase terminal.
  • N terminal — power supply neutral terminal.

OUT terminals:

  • N terminal — connected device neutral output contact terminal.
  • L terminal — connected device phase output contact terminal.

WallSwitch Operating Principle

The WallSwitch input terminals are connected to the mains cable (to the phase cable and neutral conductor), and the output terminals are connected to the socket or electrical appliance/electrical system of the room. WallSwitch turns on/off 220 V power supply according to the scenarios or at user command via the Ajax Security System application.

WallSwitch is furnished with a protection system against voltage variation beyond the range of 161V - 264V or overcurrent protection above 13А. In this case, the power supply is interrupted, resuming after normalization of the voltage and current values. 

The maximum resistive load on the relay is 3 kW.

You may view the consumed power of the electrical appliances connected via WallSwitch through the application. There is a consumed electricity meter in place.

Connecting to the Hub

Before starting connection:

  • Following the Hub instruction recommendations, install the Ajax application on your smartphone. Create an account, add the Hub to the application, and create at least one room.
  • Go to the Ajax application.
  • Switch on the Hub and check the internet connection (via Ethernet cable and/or GSM network).
  • Ensure that the Hub is disarmed and does not start updates by checking its status in the mobile application.
  • Connect WallSwitch to the power supply and wait for 30 seconds

⚠️ Only users with administrative privileges can add the device to the hub.

How to connect the WallSwitch to the Hub:

  1. Select the Add Device option in the Ajax application.
  2. Name the device, scan/write manually the QR Code (located on the body and packaging), and select the location room.

  3. Select Add — the countdown will begin.
  4. Press the WallSwitch functional button (or apply the load to the device no less than 20 W, e.g. by switching on an iron or electric kettle).

For the detection and interfacing to occur, the device should be located within the coverage area of the wireless network of the Hub (at a single protected object). Request for connection to the Hub is transmitted for a short time at the time of switching on the device.

If the connection to the Hub fails, wait for 30 seconds and retry the connection procedure.

The WallSwitch connected to the Hub will appear in the list of devices of the Hub in the application. Update of the detector statuses in the list depends on the device inquiry time set in the hub settings, with the default value - 36 seconds.

When switching on for the first time, the relay is in open status! After deleting WallSwitch from the system, the Ajax switch opens the relay!

If active, power supply will be switched off if the strength of current exceeds 11 A, in the inactive state the threshold is 16 A (or 13 A, if continues for 6 seconds)
Voltage protection
If active, power supply will be switched off in case of a voltage surge beyond the range of 161 - 264 V, in the inactive state — 0 - 500 V

The WallSwitch light indicator may light up green depending on the device status.

The green LED of WallSwitch will blink intermittently if it is not assigned to the Hub. When the functional button is pressed, the green LED lights up.

Functionality testing

The Ajax security system allows conducting tests for checking the functionality of connected devices.

The tests do not start straight away but within a period of 36 seconds when using the standard settings. The test time start depends on the settings of the detector scanning period (the paragraph on “Jeweller” settings in Hub settings).

Installation of the Device

⚠️  WallSwitch should be only installed by a qualified electrician! Regardless of the type of the electrical circuit in which the device is installed.

 WallSwitch is designed for installation inside a socket box with the diameter 50 mm and more and the depth no less than 70 mm. The relay can also be installed within extension cords and other circuits powered by 220 V.

Communication range with the Hub absent any obstacles between the devices - up to 1,000 meters. Take account of this when choosing the location for WallSwitch.

If the device has a low or unstable signal strength, use a radio signal range extender ReX.

  1. De-energize the cable to which WallSwitch will be connected.
  2. Connect the cable of the power system of the room to the WallSwitch terminals according to the following scheme

  3. Connect a socket to the WallSwitch using bundled connecting wires or an electrical appliance using a cable with the sufficient cross-section. It's recommended to use cables with cross-section of 1.5 - 2 mm2.

Do not connect more than 3 kW load to the WallSwitch. When connecting the load, strictly observe the connection diagram since an incorrect connection may cause the device to malfunction and/or damage the property.

In installing the WallSwitch in the socket box, lead out the antenna to the outside and place it under the plastic frame of the socket. The more distanced the antenna is from metal structures, the lower is the risk of screening (and impairment) of the radio signal.

In no case, do not shorten the antenna! Its length is optimal for operation within the used radio frequency range!

During installation and operation of WallSwitch, please adhere to general rules of electrical safety when using electrical appliances, as well as the requirements of electrical safety regulations. It is expressly forbidden to disassemble the device. Do not use the device with damaged power cables.

Do not install the relay:

  1. Outside 
  2. In metal wiring boxes and electrical panels
  3. In places with temperature and humidity exceeding the permissible limits.


The device does not require maintenance.
