Operating principle

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 on the website 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 identification at every communication session to protect against sabotage and spoofing.

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 firmware 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 office 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 traffic.

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 ReX 2 states 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 find and solve the problem.

A communication loss notification 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 notification is not sent.

Support of photo verification

ReX 2 radio signal range extender supports connection of detectors with photo verification. 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.

Photo delivery time via the Wings radio protocol:

* Values are calculated assuming that the hub is working via Ethernet or 4G, and there are three bars of a signal level between ReX 2 and the detector, as well as between the hub and ReX 2. If you use the Photo on Demand feature, there may be a short delay (up to 3 seconds) before the detector takes a photo.

Photo delivery time via Ethernet:

* Values are calculated assuming that the hub is working via Ethernet or 4G, and there are three bars of a signal level between ReX 2 and the detector. If you use the Photo on Demand feature, there may be a short delay (up to 3 seconds) before the detector takes a photo.

Number of connected range extenders and devices

Depending on the model, the following number of range extenders can be connected to the hub:

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.

Sending events to the monitoring station

Ajax system can connect to the CMS and transmit alarms and events in SurGard (Contact ID), SIA (DC-09), ADEMCO 685 and other proprietary protocol formats. A complete list of supported protocols is available at the link.

The ReX 2 loop (zone) number can be found in the device states. In order to obtain it:

1. Sign in to the Ajax app.
2. Select the hub if you have several of them or if you are using a PRO app.
3. Go to the Devices menu.
4. Select ReX 2. The loop (zone) number is displayed at the very bottom of the page.

The ReX 2 loop (zone) number is also available in the Groups menu (Ajax app → Devices → Hub → Settings → Groups). In order to find out the loop (zone) number, select the group in which the range extender is located. The Device Number corresponds to the loop (zone) number.

ReX 2 requires a hub for operation. List of compatible hubs:

• Hub 2 (2G)
• Hub 2 (4G)
• Hub 2 Plus
• Hub Hybrid (2G)
• Hub Hybrid (4G)

Connection to other hubs, radio signal range extenders, ocBridge Plus and uartBridge is not provided.

Connection

The range extender only works with compatible Ajax hubs. Connection to other hubs, range extenders, as well as to uartBridge and ocBridge Plus, is not provided.

Before connecting, make sure that:

1. The Ajax app is installed.
2. An account is created.
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.
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.

In order to connect ReX 2 to the hub:

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 2.
   

   To comply with the INCERT requirements, use the Screw terminal block Adapter to connect the external power supply. Read more.

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 group mode is activated).
   

   

7. Click Add; the countdown will begin.
8. Turn on ReX 2 by holding the power button for 3 seconds.
   

   

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 hub model) when attempting to add the device. In that case, you will receive a corresponding notification 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, ReX 2 is not removed from the list of devices of the old hub. This has to be done in the Ajax app.

Functionality testing

ReX 2 functionality tests do not begin immediately, but not later than over a single ping period of the hub–detector (36 seconds with the standard settings of the hub). You can change the ping period of devices in the Jeweller menu of the hub settings.

To run a test, in an Ajax app:

1. Select the hub if you have several of them or if you are using a PRO app.
2. Go to the Devices tab.
3. Select ReX 2.
4. Go to Settings .
5. Select one of the available tests:
   • Jeweller Signal Strength Test
   • Wings Signal Strength Test
   • Signal Attenuation Test

Selection of the installation site

When choosing a location, consider 2 main factors:

• Jeweller Signal Strength.
• Wings Signal Strength.

You should consider the signal strength both between the hub and the range extender and between the range extender and all devices connected to it.

Locate ReX 2 in a place with stable Jeweller and Wings signal strength (2-3 bars in the Ajax app). When choosing a site for installation, consider the distance between the range extender and the hub and any obstacles between the devices hindering the radio signal passage: walls, intermediate floors, or large-size objects located in the room.

ReX 2 should be placed between a hub and a device with a weak signal. The range extender does not amplify the radio signal, so installing it near a hub or device with a signal level of 1 or 0 bars will not give the desired result. Our radio range calculator will help you roughly calculate the signal level at the installation site.

Check the Jeweller and Wings signal strength at the installation site. If the signal strength is low (a single bar), we cannot guarantee the stable operation of the security system. At the very least, relocate the device as repositioning even by 20 cm can significantly improve the signal reception.

If the place of installation has no stable signal level (2-3 bars) via Jeweller and Wings between a range extender and a hub, use Ethernet as an additional or main communication channel. This function allows you to install range extenders in basements, metal hangars, and other places where there is no radio signal.

Ethernet can also be used as an additional communication channel with the hub. Connecting via wire and radio will increase the reliability and fault tolerance of the system.

ReX 2 should be hidden from direct view. This will help reduce the likelihood of sabotage or jamming. Also, keep in mind that the device is intended for indoor installation only.

Do not place ReX 2:

• Outdoors. Doing so may cause the device to malfunction or not work properly.
• Near metal objects or mirrors (for example, in a metal cabinet). They can shield and attenuate the radio signal.
• Inside any premises with the temperature and humidity beyond the range of permissible limits. Doing so may cause the device to malfunction or not work properly.
• Close to radio interference sources: less than 1 meter from the router and power cables. This could result in the loss of connection with the hub or devices connected to the range extender.
• In places with low or unstable signal strength if Ethernet is not used as an alternative or main communication channel. This could result in the loss of connection with the hub or devices connected to the range extender.

Installation

Before installing the range extender, make sure 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.

To install ReX 2:

1. Fix the SmartBracket mounting panel with the bundled screws. When using other fasteners, make sure they do not damage or deform the panel. When attaching, use at least two fixing points. To make the tamper react to attempts to detach the device, be sure to fix the perforated corner of SmartBracket.
   

   

   

   Do not use double-sided adhesive tape for mounting. This can cause the range extender to fall. The device may fail if hit.

2. Connect the power supply cable and an Ethernet cable (if needed) to the range extender. Turn on the device.
3. Secure the cable with a plastic retainer plate. This will reduce the likelihood of sabotage, as it takes a lot more to tear away a secured cable.
   

   

4. Slide ReX 2 onto the mounting panel. After installation, check the tamper status in the Ajax app and then the quality of the panel fixation. You will receive a notification if an attempt is made to tear the range extender off the surface or remove it from the mounting panel.
   

   

5. Fix ReX 2 on the SmartBracket panel with bundled screws.
   

   

   

   Do not turn the range extender upside down or sideways when mounting it vertically (for example, on a wall). When properly fixed, the Ajax logo can be read horizontally.

Maintenance

Check the functionality of ReX 2 regularly. The optimal frequency of checks is once every three months. Clean the body from dust, cobwebs, and other contaminants as they emerge. Use a soft, dry cloth that is suitable for equipment care.

Do not use any substances containing alcohol, acetone, gasoline and other active solvents for cleaning the range extender.

If ReX 2 battery becomes faulty and you wish to replace it, use the following guidance:
