ReX User manual
Updated January 20, 2021
ReX is a range extender of communication signals that expands the radio communication range of Ajax devices o 2-fold. Developed only for indoor use. It has a built-in tamper resistance and is equipped with a battery that provides up to 35 hours of operation without external power.
The extender is compatible only with the Ajax hubs! Connection to uartBridge and ocBridge Plus is not provided.
The device is coned via the mobile
application for iOS and Android smartphones.
Push-notifications ReX user about all events.
The Ajax security system can be used for independent monitoring of the site
and can be connected to the Central Monitoring Station of the security
company.
Functional elements
- Logo with light indicator
- SmartBracket attachment panel (perforated section is necessary to trigger the tamper during an attempt to lift the ed ReX from the surface)
- Power connector
- QR-code
- Tamper button
- Power button
Principle of operation
ReX expands the radio communication range of the security system allowing the installation of Ajax devices at a greater distance away from the hub.
The communication range between ReX and the device is limited by the radio signal range of the device (indicated in the device speci the website and in the User Manual).
ReX receives hub signals and transmits them to the devices connected to ReX, and transmits signals from the devices to the hub. The hub polls the extender every 12~300 seconds (by default: 36 seconds) while the alarms are communicated within 0.3 seconds.
The number of connected ReX
Depending on the hub model, the following number of range extenders can be connected to the hub:
Hub | 1 ReX |
---|---|
Hub Plus | up to 5 ReX |
Hub 2 | up to 5 ReX |
Hub 2 Plus | up to 5 ReX |
Connecting multiple ReX to the hub is supported by devices with OS Malevich
2.8 and later. At the same time, ReX can only be connected directly to the
hub, and connecting one range extender to another is not supported.
ReX does not increase the number of devices connected to the hub!
Connection of ReX to the hub
Prior to initiating the connection:
- Install the Ajax application onto your smartphone following the instructions of the hub guide.
- Create a user account, add the hub to the application, and create at least one room.
- Open the Ajax application.
- Turn on the hub and check the Internet connection.
- Ensure that the hub is disarmed and is not updating by checking its status in the mobile application.
- Connect ReX to external power.
Only users with administrator rights can add a device to the hub.
Connecting ReX to the hub:
- Click Add Devic e in the Ajax application.
- Name the extender, scan or manually enter the QR-code (located on the lid and package), and select the room where the device is located.
- Click Add — the countdown begins.
- Turn on ReX by pressing the power button for 3 seconds — shortly after connecting to the hub the logo will change its color from red to white within 30 seconds after ReX is switched on.
In order for detection and interfacing to occur, ReX must be located within
the radio communication range of the hub (on the same guarded facility).
The 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, turn off
the extender by pressing the power button for 3 seconds and retry the
connection procedure after 5 seconds.
The extender connected to the hub will appear in the list of hub devices in
the application. The updating of device statuses in the list depends on the
polling time set in the hub settings; the default value is 36 seconds.
Choosing devices for operation via ReX
In order to assign a device to the extender:
- Go to the ReX settings (Devices → ReX → Settings ).
- Press Pair with the device.
- Choose the devices that should operate via the extender.
- Go back to the ReX settings menu.
Once the connection is established, the selected devices will be marked with the RE icon in the mobile application.
ReX does not support pairing with MotionCam motion detector with visual alarm radio protocol.
A device can only be paired with one ReX. When a device is assigned to a range extender it is automatically disconnected from another connected range extender.
In order to assign a device to the hub:
- Go to the ReX settings (Devices → ReX → Settings ).
- Press Pair with the device.
- Uncheck the devices that need to be connected to the hub directly.
- Go back to the ReX settings menu.

Two options are available:
Entirely — the device will not execute system commands or participate in
automation scenarios, and the system will ignore device alarms and other
notifications
Lid only — the system will ignore only notifications about the triggering of
the device tamper button

devices
Note that the system will ignore only the disabled device. Devices
connected via ReX will continue operating normally

Functionality testing
The functionality testing of the associated ReX devices will be added to the next updates of OS Malevich.
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 starts depending on the settings of the detector scanning period (the paragraph on “Jeweller” in hub settings).
You can test the Jeweller signal strength between the range extender and the
hub, as well as between the range extender and the device connected to it.
To check the Jeweller signal strength between the range extender and the hub,
go to the ReX settings and select the Je weller Signal Strength Test.
To check the Jeweller signal strength between the range extender and device,
go to the settings of the device connected to ReX, and select Jeweller
Signal Strength Test.
Device installation
Selection of the installation site
The location of ReX determines its distance from the hub, the devices
connected to the extender, and the presence of obstacles preventing the
passage of the radio signal: walls, integer objects located in the facility.
The device was developed only for indoor use.
Check the signal strength at the installation site!
If the signal strength reaches just one bar on the indicator, the stable operation of the security system can not be guaranteed. Take whatever action is necessary to improve the quality of the signal! At the very least, moving ReX or hub — relocation even by 20 cm can significantly the reception quality.
Installation procedure
Before installing ReX, be sure to choose the best location that meets the
requirements of this guide! It is desirable for the extender to be hidden from
direct view.
During mounting and operating, follow the general electrical safety rules when
using electrical appliances as well as the requirements of electrical safety
laws and regulations.
Device mounting
-
Fix the SmartBracket attachment panel with the bundled screws. If you choose to use other fasteners, make sure that they do not damage or deform the panel.
It is not recommended to use double-sided adhesive tape for installation. This can result in ReX falling which can lead to the malfunctioning of the device. -
Slide ReX onto the attachment panel. After installation, check the tamper status in the Ajax application and then the panel tightness.
-
In order to ensure higher reliability, o the SmartBracket panel with the bundled screws.
Do not change the extender when attaching vertically (for instance, on a
wall).
When properly ed, the Ajax logo can be read horizontally.
You will receive a notice to detach the extender from the surface or remove it
from the attachment panel if detected.
It is strictly forbidden to disassemble the device connected to the power supply! Do not use the device with a damaged power cable. Do not disassemble or modify ReX or its individual parts — this may interfere with the normal operation of the device or lead to its failure.
Don’t place ReX:
- Outside the room (outdoors).
- Near metal objects and mirrors that cause attenuation or screening of radio signals.
- In rooms characterized by humidity and temperature levels beyond the permissible limits.
- Close to radio interference sources: less than 1 meter from the router and power cables.
Maintenance of the device
Check the functionality of the Ajax security system regularly.
Clean the body from dust, cobwebs, and other contaminants as they emerge.
Use a soft dry napkin suitable for equipment maintenance.
Do not use substances that contain alcohol, acetone, gasoline or other active
solvents to clean the extender.
