   Operating principle

   The ReX 2 Jeweller extends the radio range of the security system and provides photo verification transmission. It receives signals from the hub and sends them to the connected devices, and forwards the devices' signals back to the hub.

Principle of operation

The ReX 2 Jeweller extends the radio range of the security system by allowing Ajax devices to be installed at a greater distance from the hub.

ReX 2 Jeweller can communicate with the hub via radio (Jeweller and Wings protocols) or Ethernet cable if the devices are on the same network.

The amplifier receives signals from the hub, forwards them to the connected devices and sends the devices' signals back to the hub.

• The hub polls the ReX 2 Jeweller every 12 to 300 seconds (by settings, default value is 36 seconds).

• The ReX 2 Jeweller polls all connected devices with the same frequency.

Regardless of the settings, all alarms are transmitted within 0.3 seconds.

The communication range between the ReX 2 Jeweller and the device is limited by the radio signal range of the device itself. The radio signal range is indicated on the device page on the website and in the User Manual.

If the device loses connection to a signal amplifier for any reason, it will not automatically connect to another amplifier or hub.

Jeweller and Wings communication protocols

The signal booster uses Jeweller technology for alarm and event transmission and Wings technology for photo transmission. These are bi-directional wireless data transfer technologies that provide fast and reliable communication between the hub, the signal booster and the connected system devices.

The protocols support block encryption with dynamic keying and device identification in each communication session to protect against sabotage and tampering.

The Ajax application shall provide a 'hub-to-device' polling system at intervals of 12 to 300 seconds to monitor communications with system devices and display their status. The polling interval can be adjusted by the user or by a PRO with administrator rights.

Connection via Ethernet

ReX 2 Jeweller with OS Malevich 2.13 firmware supports connection to the hub via radio and Ethernet. Using a cable connection, a single Ajax system can cover sites such as an office centre with underground parking, a metal hangar or a warehouse complex of several large buildings. Ethernet can be the only communication channel or run in parallel with Jeweller and Wings. If ReX 2 Jeweller is connected to the hub via both Ethernet and radio channels, Ethernet is preferred.

The Hub and the ReX 2 Jeweller must be connected to the same network via a router for this communication channel to work. The router is needed to determine the IP address of the signal booster. The network to which the ReX 2 Jeweller connects shall support broadcast requests and provide an open port 4269 for all data transmissions.

A direct connection to the hub via Ethernet cable is not foreseen.

The ReX 2 Jeweller can operate with both static and dynamic IP addresses. If the signal booster fails to establish an Ethernet connection to the hub, an error will be displayed in the ReX 2 Jeweller status. For convenience, the MAC address of the signal booster is also available in the error information to help find and fix the problem.

A connection loss notification is sent in two cases: if the hub loses connection to the signal booster completely or if the connection to the booster is lost over the photo transmission channel. If the connection is lost only via Jeweller or only via Wings (if Ethernet is connected), no notification is sent.

Photo verification support

The ReX 2 Jeweller radio signal booster supports the addition of detectors with photo verification. ReX 2 Jeweller can not only transmit events and alarms, but also photos taken by the detector.

The photo delivery time through the amplifier depends on the communication channel with the hub, the type of detector and the resolution of the image.

Photo delivery time via Wings radio protocol:

¹ Values are calculated assuming the hub is running over Ethernet or 4G and the signal level between the ReX 2 Jeweller and the detector and between the hub and the ReX 2 Jeweller is three bars. When using the "Photo on Demand" function, there may be a slight delay (up to 3 seconds) before the detector takes a photo.

To run a test in the Ajax app:

• Select a room if there are several.

• Open the Devices tab.

• Select ReX 2 Jeweller.

• Go to Settings.

• Select one of the available tests:

  • Jeweller Signal Strength Test

  • Wings signal strength test

  • Signal attenuation test

Selecting the installation location

There are 2 main factors to consider when selecting an installation site:

• Jeweller signal strength.

• Wings signal strength.

The signal strength between the hub and the signal amplifier and between the signal amplifier and all connected devices must be assessed.

Place the ReX 2 in a Jeweller location with stable Jeweller and Wings signal strength (2-3 bars in the Ajax app). When choosing the installation location, take into account the distance between the signal booster and the hub, as well as obstacles between the devices that prevent the radio signal from propagating: walls, ceilings or large objects in the room.

ReX 2 Jeweller should be placed between the hub and a device with a weak signal. The signal booster does not increase the power of radio signals, so placing it next to a hub or device with a signal level of 1 or 0 bars will not give the desired result. Use our radio signal range calculator to estimate the signal level at the installation site.

Check the signal strength of Jeweller and Wings at the installation site. If the signal strength is low (one pole), we cannot guarantee stable operation of the security system. Moving the device even 20 cm can significantly improve signal reception.

If there is no stable signal level (2-3 bars) between the signal booster and the hub at the installation site via Jeweller and Wings, use Ethernet as the main communication channel. This feature allows signal boosters to be installed in basements, metal hangars and other locations where radio signals are not available.

Ethernet can be the only communication channel or run in parallel with radio protocols. Connection via both cable and radio will increase system reliability and operational reliability. In this configuration, the Ethernet channel is preferred.

The ReX 2 Jeweller shall be positioned so that it is not directly visible. This will help reduce the likelihood of sabotage or interference. Remember that the device is intended for indoor use only.

Do not install the ReX 2 Jeweller:

• Outdoors. This may cause the device to malfunction or completely stop working.

• Close to metal objects or mirrors (e.g. in a metal cabinet). These can obscure and weaken the radio signal.

• In rooms where the temperature and humidity exceed the permissible limits. This may cause the device to malfunction or completely stop working.

• Close to sources of radio interference: closer than 1 metre from the router and power cables. This may cause loss of connection to the hub or devices connected to the signal amplifier.

• In areas with low or unstable signal strength, if Ethernet is not used as the main communication channel. This may cause loss of connectivity to the hub or devices connected to the signal booster.

Installation

Before installing the signal booster, make sure that you have selected the optimum location and that it meets the requirements of this manual.

When installing and operating the device, observe the general rules for electrical safety in the use of electrical appliances and the requirements of the electrical safety regulations.

To install the ReX 2 Jeweller:

• Secure the SmartBracket mounting panel with the screws provided. When using other fasteners, make sure that they do not damage or deform the panel.

• Use all fixing points when attaching.

• Be sure to secure the SmartBracket's perforated corner so that the sabotage sensor responds to attempts to disconnect the device.

1. 

   

   Do not use double-sided adhesive tape for mounting. This can cause the signal amplifier to fall off. The device may be damaged by impact.

   Connect the power cable and, if necessary, the Ethernet cable to the signal amplifier. Switch on the device.

   Secure the cable with the plastic locking plate. This will reduce the risk of sabotage as it is much more difficult to tear off a fixed cable.

   Slide the ReX 2 Jeweller onto the mounting panel. After installation, check the status of the sabotage sensor in the Ajax app and then the quality of the fixing of the panel. You will receive a notification if an attempt is made to pull the signal amplifier off the surface or remove it from the mounting panel.
   

   

   Secure the ReX 2 Jeweller to the SmartBracket panel with the screws provided.
   

   

   

   Do not install the signal amplifier inverted or sideways if it is mounted vertically (e.g. on a wall). When properly mounted, the Ajax logo is readable horizontally.

   Maintenance

   Check the operation of the ReX 2 Jeweller regularly. The optimum frequency is every three months. Clean the housing of dust, cobwebs and other dirt as it appears. Use a soft, dry cloth designed for the care of machinery.

   Do not use substances containing alcohol, acetone, benzine or other active solvents for cleaning.

   If the ReX 2 Jeweller battery becomes damaged and you wish to replace it, use the following instructions:
