ReX 2 User Manual
Updated May 21, 2022
ReX 2 is a radio signal range extender of a security system with support for
alarm photo verication. Communicates with the hub via radio and Ethernet. It is
designed for indoor installation.
It has a built-in tamper for protection against tampering and is equipped with a
backup battery for 38 hours of battery life.
The range extender only works with . Connection to other hubs,
range extenders, as well as to and , is not provided.
The device is added to the system and congured via iOS, Android, macOS, and
Windows . Users will know about ReX 2 events through push notications,
SMS, and calls (if enabled).

Functional elements
Operating principle
1. Logo with an LED indicator.
2. SmartBracket mounting panel. Slide it down with force to open.
The perforated part is necessary for tamper triggering in case of any attempt to
detach the range extender from the surface. Do not break it off.
3. Power cable connector.
4. Ethernet cable connector.
5. QR code with the identier (service number) of the range extender.
6. Tamper button.
7. Power button.
ReX 2 expands the radio communication range of the security system, allowing
the installation of Ajax devices at a greater distance away from the hub. ReX 2
can communicate with the hub via radio (the Jeweller and Wings protocols) and
Ethernet cable if the devices are within the same network.
ReX 2 receives hub signals, transmits them to the connected devices, and sends
signals from devices to the hub. The hub polls range extender with the
frequency of 12 to 300 seconds (depending on the settings, the default value is
36 seconds). ReX 2 range extender polls all connected devices with the same
frequency.
Regardless of the settings, all alarms are delivered in no more than 0.3 seconds.
The communication range between ReX 2 and the device is limited by the radio
signal range of the device. Radio signal range is indicated on the device page
and in the User Manual.
If the device loses communication with a range extender for some reason, it
does not automatically connect to another range extender or hub.

Jeweller and Wings communication protocols
Range extender uses Jeweller technology to transmit alarms and events and
Wings to transmit photos. These are two-way wireless data protocols for data
transmission that provide fast and reliable communication between the hub,
range extender and system devices connected to a range extender.
The protocols support block encryption with dynamic key and device
identication at every communication session to protect against sabotage and
spoong.
To control communication with system devices and display their statuses, the
Ajax app provides a “hub — devices” polling system with an interval of 12 to 300
seconds. The polling interval is adjusted by the user or PRO with admin rights.
Connection via Ethernet
ReX 2 with the OS Malevich 2.13 rmware supports connection to the hub via
radio and Ethernet. The cable can be used as the only or additional
communication channel. A single Ajax system can now cover such an object as
an oce centre with underground parking, a metal hangar, or a warehouse
complex of several large buildings.

The hub and ReX 2 must be connected to the same network through a router for
this communication channel to work. The router is needed to determine the IP
address for the range extender. The network to which ReX 2 connects must
allow broadcast queries and an open 4269 port for all types of trac.
Connecting ReX 2 directly to the hub via an Ethernet cable is not provided.
ReX 2 can work with both static and dynamic IP addresses. If the range extender
is unable to establish an Ethernet connection with the hub, the will
display a malfunction. For convenience, the MAC address of the range extender
is also available in the error details, which can be used to nd and solve the
problem.
A communication loss notication is sent in two cases: if the hub completely loses
connection with the range extender, and also if the hub loses connection with the range
extender via the photos transmitting channel. If communication via Jeweller only or via
Wings only is lost (when Ethernet is connected), a notication is not sent.
Support of photo verication
ReX 2 radio signal range extender supports connection of
. ReX 2 range extender can transmit not only events and alarms but
also photos taken by the detectors.
Photo delivery time via range extender depends on the channel of the
communication with a hub, the type of detector and the resolution of the
images.

It doesn’t matter exactly what type of range extender is used: ReX or ReX 2.
They can be connected to the system in any combination within the hub
limitations.
ReX 2 connects to the hub only directly. Connection to another range extender is
not provided.
ReX 2 does not increase the number of devices connected to the hub. The
maximum number of devices connected to ReX 2 depends on the hub model.
Hub model Number of connected devices

3. The required hub has been added to the Ajax app.
4. This hub is enabled and at least one room has been created for it.
In order to connect ReX 2 to the hub:
5. You have administrator rights for this hub.
6. The hub has internet access via at least one communication channel:
Ethernet, Wi-Fi, or a cellular connection. You can check this in the Ajax app
or through the hub logo on the faceplate. The logo should light up white or
green.
7. The hub is disarmed and is not being updated. You can check this through
the status of the hub in the Ajax app.
1. Remove the SmartBracket mounting panel by sliding it down with force. Do
not damage the perforated portion as it is needed to trigger the tamper
protecting the range extender from dismantling.
2. Connect ReX 2 to external power supply. Connect an Ethernet cable to ReX

3. Sign in to the Ajax app.
4. Select the hub if you have several of them or if you are using a PRO app.
5. Go to the Devices tab and click Add Device.
6. Name the range extender, scan or enter the QR code manually (indicated on
the device body and packaging), and select a room and a group (if the
is activated).

To make sure ReX 2 is connected to the hub, the range extender must be located at the
same secured facility as the system (within the range of the hub’s radio network).
After connecting to the hub, the logo will change its colour from red to white
within 30 seconds. The connected range extender will appear in the list of hub
devices in the Ajax app. The updating rate of the range extender states depends
on the Jeweller settings (or Jeweller/Fibra for the Ajax hybrid hubs); the default
value is 36 seconds.
If the connection fails, turn off ReX 2 and try again after 5 seconds. Suppose the
maximum number of devices has been added to the hub (depending on the
) when attempting to add the device. In that case, you will receive a
corresponding notication in the Ajax app.
ReX 2 only works with one hub. When connected to a new hub, the range
extender stops sending commands to the old one. Once added to a new hub,
