   Operating principle
   The ReX Jeweller extends the radio communication range of the security system, allowing Ajax devices to be installed at a greater distance from the hub.

Communication range
The communication range between ReX Jeweller and the device is limited by the range of the device's own radio signal (specified in the device specification on the website and in the user manual).

Operation
The ReX receives signals from the hub and forwards them to the connected devices, as well as returning signals from the devices back to the hub. The Hub checks the amplifier every 12-300 seconds (default every 36 seconds), while alarms are transmitted within 0.3 seconds.

Number of connected ReX Jeweller

Depending on the Hub model, the following number of signal boosters can be added:

• Hub - 1 ReX Jeweller

• Hub Plus - up to 5 ReX Jeweller

• Hub 2 (2G) - up to 5 ReX Jeweller

• Hub 2 (4G) - up to 5 ReX Jeweller

• Hub 2 Plus - up to 5 ReX Jeweller

• Superior Hub Hybrid - up to 5 ReX Jeweller

Multiple ReX Jeweller connections are supported on devices running Malevich OS 2.8 and later. ReX Jeweller can only be connected directly to the hub - cross-amplifier connections are not supported.
⚠️ ReX Jeweller does not increase the total number of devices that can be connected to the hub!

Connecting ReX Jeweller to a Hub

• Hub and devices operating on different radio frequencies are not compatible.

• Radio frequency range may vary by region. It is recommended to purchase and use Ajax devices in the same region.

• Working radio frequencies can be checked with technical support.

Before connecting the device

1. Install the Ajax app or Ajax PRO.

2. Sign in to an existing account or create a new one.

3. Select an existing Space or create a new one.

   • Space functionality is available from the following versions or later:

     • Ajax Security System 3.0 iOS

     • Ajax Security System 3.0 for Android

     • Ajax PRO: Tool for Engineers 2.0 iOS

     • Ajax PRO: Tool for Engineers 2.0 Android

     • Ajax PRO Desktop 4.0 macOS

     • Ajax PRO Desktop 4.0 Windows

4. Add at least one virtual room(Room).

5. Connect a compatible hub to this Space. Make sure the hub is switched on and has internet access (Ethernet, Wi-Fi and/or mobile network).

6. Make sure the system is disarmed and the hub is not performing an update (statuses visible in the Ajax app).

⚠️ Only a user with administrator rights can add a device to the hub.

Connecting

• Open the Ajax app and select Add Device.

• Name the amplifier, scan or manually enter the QR code (located on the cover and packaging).

• Select the room where the device will be installed.

1. 

2. Connection process

   1. In the app, press Add - a countdown timer will start.

   2. Switch on ReX Jeweller by holding the power button down for 3 seconds.

   3. Once connected to the hub, the device logo will change colour from red to white (within 30 seconds of switching on).

3. 

Detection and connection
For connection and detection to take place, the ReX Jeweller must be within radio communication range of the hub (in the same guarded area).

The connection request with the hub is only sent when the device is switched on.
If the connection with the hub fails:

• Switch off the amplifier by pressing the power button for 3 seconds,

• Repeat the connection procedure after 5 seconds.

Once connected to the hub, the amplifier will appear in the app in the device list. The update interval of the device status in the list depends on the polling time set in the hub settings (default value 36 seconds).

Assigning devices to work via ReX Jeweller
To add a device to the booster:

1. Open the ReX Jeweller settings (Devices → ReX Jeweller → Settings).

2. Press Pair with device.

3. Select the devices that will work through the amplifier.

4. Return to the ReX Jeweller settings menu.

Once connected, the selected devices will be marked with the 🔗 icon in the mobile app.

LED indication

The ReX Jeweller LED indicator may glow red or white depending on the device state.

Functionality check

A test for ReX Jeweller connected devices will be added in future OS Malevich updates.

The Ajax system allows tests to be run to verify the functionality of connected devices. Tests are not initiated immediately, but within up to 36 seconds if standard settings are used. The start time depends on the polling interval settings of the detector(Jeweller section in the hub settings).

Can be checked:

• Jeweller signal strength between ReX Jeweller and the hub;

• Jeweller signal strength between ReX Jeweller and the connected device.

Starting the test:

• To test the signal strength between the amplifier and the hub - open the ReX Jeweller settings and select Jeweller Signal Strength Test.

• To test the signal strength between the amplifier and the connected device - open the settings of the connected device and select Jeweller Signal Strength Test.

Device Setup

Site selection

The location of the ReX Jeweller determines the distance to the hub, the connected devices and the effect of obstacles (walls, covers, large objects) on the propagation of the radio signal.

• The device is intended for indoor use only.

• Be sure to check the signal strength at the selected location!

• If the indicator shows only one level, stable operation is not guaranteed. To improve the signal, move the ReX Jeweller or hub - even a 20 cm movement can significantly improve reception.

Installation procedure

1. Choose a location that meets the requirements of the manual, preferably hidden from direct view.

2. Observe electrical safety rules and regulations during installation.

3. Secure the SmartBracket mounting panel with the screws provided.

   • If you use other fasteners, make sure that the panel is not damaged or deformed.

   • It is not recommended to use double-sided tape as this may cause the device to fall off and be damaged.

4. Slide the ReX Jeweller onto the mounting panel.

5. After installation, check the tamper status in the Ajax app and the rigidity of the panel.

6. For extra security, secure the ReX Jeweller to the SmartBracket panel with the supplied screws.

Installation security

• Do not install the amplifier in an inverted manner in a vertical mounting (e.g. on a wall). In the correctly fixed position, the Ajax logo is readable horizontally.

• If an attempt is made to remove the unit from the surface or disconnect it from the mounting panel, the user will receive a message.

• The device must not be disassembled while it is connected to power.

• It is forbidden to use the appliance with a damaged power cable.

• Do not disassemble or modify the ReX Jeweller or its components - this may cause malfunction or complete destruction of the device.

It is forbidden to install the ReX Jeweller

• Outdoors.

• Near metal objects or mirrors that attenuate or block radio signals.

• In rooms with humidity or temperature levels exceeding the permitted limits.

• Closer than 1 metre to the router or power cables (sources of radio interference).

Maintenance

• Check the Ajax system regularly.

• Clean the housing of dust, spider webs and other dirt using a soft dry cloth designed for the care of machinery.

• Do not use substances containing alcohol, acetone, petrol or other active solvents.
