AJAX Systems ReX Manuale utente
Posted on May 27, 2021
ReX is a range extender of communication signals that expands the radio
communication range of Ajax devices fitted with a hub up to 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 ! Connection to and
is not provided.
The device is configured via the for iOS and Android
smartphones. Push-notifications, SMS messages and calls (if enabled) notify
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.
ReX expands the radio communication range of the security system allowing
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 specifications on
theand 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
1. Logo with light indicator
2. SmartBracket attachment panel (perforated section is necessary to trigger
the tamper during an attempt to lift the fixed ReX from the surface)
3. Power connector
4. QR-code
5. Tamper button
6. Power button
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!
Only users with administrator rights can add a device to the hub.

2. Create user account, add the hub to the application, and create at least one
room.
3. Open theAjax application.
4. Turn on the hub and check the Internet connection.
5. Ensure that the hub is disarmed and is not updating by checking its status in
the mobile application.
6. Connect ReX to external power.
1. ClickAdd Devicein the Ajax application.
2. Name the extender, scan or manually enter theQR-code(located on the lid
and package), and select the room where the device is located.
3. ClickAdd— the countdown begins.
In order for detection and interfacing to occur, ReX must be located within 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.
1. Go to the ReX settings (Devices →ReX →Settings ).
2. PressPair with device.
3. Choose the devices that should operate via the extender.
4. Go back to the ReX settings menu.
ReX does not support pairing with motion detector with visual alarm
verification since the latter uses additional Wings 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.

The functionality testing of the associated to 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 start depends 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 Jeweller 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.
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, interfloor bridgings, and large objects located in the facility.
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, move ReX or hub
— relocation even by 20 cm can significantly improve the reception quality.
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.
1. 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 that can lead to malfunctioning of the device.
2. Slide ReX onto the attachment panel. After installation, check the tamper
status in the Ajax application and then the panel tightness.
3. In order to ensure higher reliability, fix ReX to the SmartBracket panel with
the bundled screws.
