AJAX Wall Switch

Wall Switch

WallSwitch is a wireless indoor power relay featuring a power consumption meter. The miniature body of the device is adapted for installation in a European-type socket.

Regardless of the type of electrical circuit, only a qualified electrician should install WallSwitch!

WallSwitch operates only within the Ajax security system (integration into third-party security systems is not provided), communicating with a hub via the protected Jeweller protocol. The communication range is up to 1,000 meters in the line of sight.

Use scenarios to program actions of automation devices (Relay, WallSwitch, or Socket) in response to an alarm, Button press, or schedule. A scenario can be created remotely in the Ajax app.

How to create and configure a scenario in the Ajax security system

The Ajax security system can be connected to the central monitoring station of a security company.

OUT terminals:

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

Operating Principle

WallSwitch input terminals are connected to the grid, and the output terminals are connected to the socket or electrical appliance/system. WallSwitch closes/opens the electric circuit, controlling the power supply by the command of the security system user through the Ajax app. The state of WallSwitch contacts can be switched manually: by holding the function button for 2 seconds. To make WallSwitch react to alarm or schedule automatically, you can configure a scenario.

WallSwitch features a protection system against voltage surge beyond the range of 184V – 253V or overcurrent above 13А. In this case, the power supply is interrupted, resuming after normalizing the voltage and current values.

The maximum resistive load on the relay is 3 kW.

You can check the power usage by the electrical appliance connected via WallSwitch through the app. There is a power consumption meter.

WallSwitch, with firmware version 5.54.1.0 and higher, can operate in pulse orbistable mode. With this firmware version, you can also select the normal relay contact state:

Normally closed (NC) — the contacts open when the relay is activated and closed when the relay is inactive.
Normally open (NO) — the contacts close when the relay is activated and open when the relay is inactive

WallSwitch, with firmware version below 5.54.1.0, only works in bistable mode with a normally open contact.

How to find out the firmware version of the device?

At low loads (up to 25 W), current and power consumption indications may be displayed incorrectly due to hardware limitations.

Connecting to the hub

Before connecting the device

Switch on the hub and check its Internet connection (the logo glows white or green).
Install the Ajax app. Create the account, add the hub to the app, and create at least one room.
Make sure that the hub is not armed, and it does not update by checking its status in the Ajax app.

Only users with administrator rights can add a device to the app

To pair WallSwitch with the hub

Click Add device in the Ajax app.
Name the device, scan it, or enter the QR code manually (located on the caseand packaging), select the room.
Click Add — the countdown will begin.
Press the functional button. If you can’t do this (the device is mounted in the wall), give WallSwitch at least 20 W load for five seconds (by connecting and disconnecting a working kettle or lamp).

For detection and pairing to occur, the device should be located in the coverage area of the hub’s wireless network (at the same object). The connection request is transmitted only at the moment of switching on the device.

If the device failed to pair, wait 30 seconds and then retry. WallSwitch will appear in the list of hub devices.

The device statuses update depends on the ping interval set in the hub settings. The default value is 36 seconds.

When switching on for the first time, WallSwitch contacts are open! When deleting WallSwitch from the system, contacts open!

Indication

The WallSwitch light indicator can light green depending on the device status.

When not paired with the hub, the light indicator blinks periodically. When the functional button is pressed, the light indicator lights up.

Functionality testing

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

The tests do not start immediately but within a period of 36 seconds when using default settings. The test time start depends on the settings of the detector ping interval (the Jeweller menu in the hub settings)

Installation of the Device

Regardless of the type of electrical circuit, only a qualified electrician should install WallSwitch!

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 230 V.

The communication range with the hub in the line of sight is up to 1,000 meters. Take this into account when choosing the location for WallSwitch.

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

Installation process

De-energize the cable to which WallSwitch will be connected.
Connect the grid wire to the WallSwitch terminals according to the following scheme:
Connect a socket using bundled connecting wires or an electrical appliance using a wire with the sufficient cross-section to WallSwitch. It’s recommended to use wires with a cross-section of 1.5 – 2 mm².

Do not connect more than 3 kW load to 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.

When installing WallSwitch in the box, lead out the antenna and place it under the plastic frame of the socket. The bigger the distance between the antenna and metal structures, the lower the risk of interfering (and impairment) of the radio signal.

Do not shorten the antenna! Its length is optimal for operation within the used radio frequency range!

During the installation and operation of WallSwitch, follow the general electrical safety rules and the requirements of electrical safety regulatory acts.

It is strictly forbidden to disassemble the device. Do not use the device with damaged power cables

Do not install the relay

Outdoors.
In metal wiring boxes and electrical panels.
In places with temperature and humidity exceeding the permissible limits.
Closer than 1 m to a hub.

Maintenance

The device does not require maintenance
