Operating principle

WallSwitch is a power relay of the Ajax system. The relay is installed in the electrical circuit gap to control the power supply of devices connected to this circuit. The relay can be controlled via the function button on the device (by holding it down for 2 seconds), the Ajax app Button , , and automation scenarios .
WallSwitch switches one single pole of the electrical circuit — the phase. In this case, the neutral is not commuted and remains closed.
WallSwitch can operate in bistable or pulse mode (pulse mode is available with ). The pulse duration can be set in pulse mode from 1 to 255 seconds. The operating mode is selected by users or PRO with admin rights in Ajax apps. rmware version 5.54.1.0 and higher The user or PRO with administrator rights can also set the normal state of the relay contacts (the function is available for WallSwitch with ): rmware version 5.54.1.0 and higher

• Normally closed — the relay stops supplying power when activated and resumes when deactivated.
• Normally open — the relay supplies power when activated and stops when deactivated.

WallSwitch measures the current, voltage, the amount of energy consumed by electrical appliances, and the power they consume. This data, along with other operating parameters of the relay, is available in the device States . Relay states update frequency depends on Jeweller or Jeweller/Fibra settings; the default value is 36 seconds.
The maximum resistive load of the relay is 3 kW. If an inductive or capacitive load is connected, the maximum switching current drops to 8 A.

Automation scenarios

Ajax’s scenarios offer a new level of protection. With them, the security system not only noties about a threat, but also actively resists it.
Scenario types with WallSwitch and examples of usage:

• By alarm. Lighting is switched on when an opening detector raises the alarm.
• By security mode change. The electric lock is automatically blocked when the object is armed.
• By schedule. The irrigation system in the yard is switched on according to the schedule for the specied time. Lighting and TV are switched on when the owners are away so the house doesn’t seem empty.
• By pressing Button. Switching on night lighting by pressing the smart button.
• By temperature. The heating is turned on when the temperature in the room is lower than 20°C.
• By humidity. The humidier is switched on when the humidity level drops below 40%.
• By CO₂ concentration. Supply ventilation is turned on when the carbon dioxide concentration level exceeds 1000 ppm.

Scenarios by the Button pressing are created in the , scenarios by the humidity and CO₂ concentration levels are created in the . Button settings LifeQuality settings

More about scenarios

Control via the app

In Ajax apps , a user can switch on and off electrical appliances connected to an electrical circuit controlled by WallSwitch.
Click the toggle in the WallSwitch eld in the Devices menu: the state of the relay contacts will change to the opposite, and the connected electrical device will switch off or on. This way, a security system user can remotely control the power supply, for example, for a heater or a humidier.
When WallSwitch is in pulse mode, the toggle will change from on/off to pulse.

Protection types
WallSwitch has three types of protection that operate independently: voltage, current, and temperature.
Voltage protection: is activated if the supply voltage exceeds the range of 184– 253 V~ (for 230 V~ grids) or 92–132 V~ (for 110 V~ grids). Protects connected devices from voltage surges. We recommend disabling this protection for WallSwitch with rmware version below 6.60.1.30, which is connected to 110 V~ grids.
Current protection: is activated if the resistive load exceeds 13 A and inductive or capacitive load exceeds 8 A. Protects relays and connected devices from overcurrent.
Temperature protection: is activated if the relay heats up to temperatures above 65°C. Protects the relay from overheating.
When voltage or temperature protection is activated, the power supply through WallSwitch is stopped. Power supply resumes automatically when voltage or temperature returns to normal.
When the current protection is activated, the power supply will not be restored automatically; the user needs to use the Ajax app for this.

Energy consumption monitoring
In the Ajax app, the following energy consumption parameters are available for appliances connected via WallSwitch:

• Voltage.
• Load current.
• Power consumption.
• Power consumed.

Update frequency of parameters depends on Jeweller or Jeweller/Fibra polling period (default value is 36 seconds). Power consumption values are not reset in the app. To reset the readings, temporarily power off WallSwitch.

Jeweller data transfer protocol
WallSwitch uses the Jeweller radio protocol to transmit alarms and events. This wireless protocol provides fast and reliable two-way communication between the hub and connected devices.
Jeweller supports block encryption with a oating key and authentication of devices at each communication session to prevent sabotage and device spoong. The protocol involves regular polling Ajax devices by the hub at intervals of 12 to 300 seconds (set in the Ajax app) to monitor communication with all devices and display their statuses in the app.

Sending events to the monitoring station

The Ajax system can transmit alarms and events 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 proprietary protocols.
Which CMSs can Ajax hubs be connected to With PRO Desktop, the CMS operator receives all WallSwitch events. With other CMS software, a monitoring station receives only notication about connection loss between WallSwitch and the hub (or range extender).
The addressability of Ajax devices allows sending not only events but also the type of the device, its name, and room to PRO Desktop/CMS (the list of transmitted parameters may vary depending on the type of the CMS and the selected communication protocol).

The relay ID and zone number can be found in the WallSwitch States in the Ajax app.

Selecting the installation spot

The device is connected to the 110/230 V~ grid. The WallSwitch dimensions (39 × 33 × 18 mm) allow installing the device into the deep junction box, inside the electrical appliance enclosure, or in the distribution board. A exible external antenna ensures stable communication. To install WallSwitch on a DIN rail, we recommend using a DIN Holder.
WallSwitch should be installed with a stable Jeweller signal strength of 2–3 bars. To roughly calculate the signal strength at the place of installation, use a . Use a radio communication range calculator radio signal range extender if the signal strength is less than 2 bars at the intended installation location.
Do not install WallSwitch:

1. Outdoors. Doing so may cause the device to malfunction or not work correctly.
2.  In rooms where the humidity and temperature do not correspond to the operating parameters. Doing so may cause the device to malfunction or not work correctly.
3. Near sources of radio interference: for example, at a distance of less than 1 meter from a router. This can lead to a loss of connection between WallSwitch and the hub (or range extender).
4. In places with low or unstable signal strength. This can lead to a loss of connection between the relay and the hub (or range extender).

Installing

Only a qualied electrician or installer should install WallSwitch.

Before installing the relay, ensure that you have selected the optimal location 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.
When installing WallSwitch in the junction 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 with and deteriorating the radio signal.

When connecting, it is recommended to use cables with a cross-section of 0.75 —1.5 mm² (22-14 AWG). WallSwitch should not be connected to circuits with a load of more than 3 kW.

To install WallSwitch:

1. If you install WallSwitch on a DIN rail, x DIN Holder to it rst.

2.  De-energize the power cable to which WallSwitch will be connected.

3.  Connect the phase and neutral to the power terminals of WallSwitch. Then connect the wires to the output terminals of the relay.

4.  Place the relay in DIN Holder. If the relay is not mounted on the DIN rail, we recommend securing WallSwitch with double-sided tape if it’s possible.

5. Secure the wires if necessary.

Do not shorten or cut the antenna. Its length is optimal for operation in the Jeweller radio frequency range.
After installing and connecting the relay, be sure to run the Jeweller Signal Strength Test, and also test the overall operation of the relay: how it responds to commands, and whether it controls the power supply of the devices.

Connecting

Before connecting the device

1. Install the Ajax app . Log in to your account or create a new account if you don’t have one.
2.  Add a compatible hub to the app, make the necessary settings, and create at least one virtual room .
3.  Make sure that the hub is on and has Internet access via Ethernet, Wi-Fi, and/or mobile network. You can do this in the Ajax app or by checking the hub LED indicator. It should light up white or green.
4. Make sure the hub is not armed and does not start updates by checking its status in the Ajax app.
   Only a user or a PRO with admin rights can connect the relay to the hub.

In order to connect WallSwitch to the hub

1. Connect WallSwitch to a 110–230 V⎓ supply circuit if you haven’t done this before, and wait for 30 to 60 seconds.

2. Sign in to the Ajax app.

3. Select a hub if you have several of them or if you are using the PRO app.

4. Go to the Devices menu and click Add Device.

5. Name the device, select the room, scan the QR code (located on the relay and its packaging), or type the ID of the device.

6. Click Add; the countdown will begin.

7. Press the function button on WallSwitch. If this is not possible (for example, if WallSwitch is installed in a junction box), apply a load of at least 20 W to the relay for 5 seconds. For example, turn on the kettle, wait a few seconds, and turn it off.

To add WallSwitch, it must be within the hub’s radio coverage. If the connection fails, try again in 5 seconds.
If the maximum number of devices is added to the hub, when the user tries to add WallSwitch, he will get a notication about exceeding the device limit in the Ajax app. The maximum number of devices connected to the hub depends on the central unit model .
WallSwitch only works with one hub. When connected to a new hub, it stops sending notications to the previous one. Once added to a new hub, WallSwitch is not removed from the list of devices of the old hub. This has to be done in the Ajax app.
After pairing with the hub and removing from the hub the relay contacts are open.

Malfunctions counter

In case of a WallSwitch fault (e.g., no Jeweller signal between the hub and the relay), the Ajax app displays a malfunction counter in the upper-left corner of the device icon.
Malfunctions are displayed in the relay States . Fields with malfunctions will be highlighted in red.

Malfunction is displayed if:

• Current protection was activated.
• Temperature protection was activated.
