  2. Go to the Devices menu .
  3. Select ReX 2 from the list of devices.
  4. Go to the range extender settings by clicking the gear icon.
  5. Click Ethernet Settings.
  6. Disable the Connection via Ethernet option.

Internal tests and feedback from partners show that the system can work stably with Wi-Fi bridges, VPN tunnels and networks where there are no traffic restrictions.

We cannot guarantee a stable system operation under any other conditions or with any other equipment. Therefore, before installing devices, we recommend testing the system with the network equipment you plan to use.

Note that the network to which ReX 2 is connected must allow broadcast requests, and the 4269 port must be open for all types of traffic.

No. Both ReX 2 and the hub must be connected via Ethernet for this communication channel to work.

In this case, all alarms, events and photos are transmitted via Ethernet.

If ReX 2 loses connection with the hub via Ethernet, the range extender continues to transmit all alarms, events and photos via radio.

If the range extender loses connection with the hub through both communication channels — users and the security company receive notifications about the loss of connection with the range extender and all the connected devices. The time it takes to send messages depends on the hub settings: the Jeweler settings for hubs that support Ajax wireless devices and the Jeweler/Fibra settings for hubs that support wired and wireless devices.

The identifier (ID) is the serial number of the device. It is located under the QR code on the body, board, and packaging of the device.

ID under the lid

The ID can also be found in the device states in the Ajax app.

  1. Sign in to the Ajax app.
  2. Select the required hub from the list if you have several of them or if you are using a PRO app.
  3. Go to the Devices menu.
  4. Select a device from the list. Device ID information is located at the bottom of the status screen.

ReX 2 with a standard power supply unit operates off 110-240 VAC mains.

To connect ReX 2 to 12 V circuits, use 12V PSU.

12V PSU is required to connect the range extender to the power system of a car, trailer, yacht, or an external battery/power supply.

To connect ReX 2 to 6 V circuits, use 6V PSU.

6V PSU is required to allow the range extender to run on an external battery for years — without being connected to the facility’s electric power system — and be ready to protect run-down or empty premises as well as buildings under construction against burglars, vandals, or unauthorized occupants.

You can calculate the run time of ReX 2 from an external battery using a calculator.

Central panels: ReX 2 can be connected to Hub 2 (2G), Hub 2 (4G), Hub 2 Plus, Hub Hybrid (2G), Hub Hybrid (4G).

Range extenders: ReX 2 cannot be connected to another radio signal range extender.

Integration modules: ReX 2 cannot be connected to ocBridge Plus and uartBridge.

Power supplies: ReX 2 is compatible with 12V PSU for Hub 2/ReX 2 and 6V PSU for Hub 2/Hub 2 Plus/ReX 2.

Other devices: ReX 2 is compatible with all Ajax devices that support Jeweller and/or Wings radio protocols.

Copied

You can connect up to 5 ReX 2 range extenders to a compatible hub. Connection to another range extender is not provided.

The list of compatible hubs is available at the link. Connection to other hubs and ocBridge Plus and uartBridge integration modules is not provided.

The delivery time for photo verifications via ReX 2 range extender depends on the hub communication channel, type of detector and the resolution of the images.

Photo delivery time through the Wings radio protocol:

Detector Photo resolution (pixels) Photo delivery time via range extender
MotionCam Jeweller
MotionCam (PhOD) Jeweller
160 × 120 Up to 8 seconds
320 × 240 (default) Up to 18 seconds
640 × 480 Up to 31 seconds
MotionCam Outdoor Jeweller
MotionCam Outdoor (PhOD) Jeweller
320×176 (default) Up to 13 seconds
640 × 352 Up to 30 seconds

Values provided that the hub works via Ethernet or 4G, and there are three bars of signal strength between ReX 2 and the detector, and between the hub and ReX 2. If you use the Photo on Demand feature, there may be a delay of up to 3 seconds before the detector takes a photo.

Photo delivery time via Ethernet:

Detector Photo resolution (pixels) Photo delivery time via range extender
MotionCam Jeweller
MotionCam (PhOD) Jeweller
160 × 120 Up to 6 seconds
320 × 240 (default) Up to 10 seconds
640 × 480 Up to 17 seconds
MotionCam Outdoor Jeweller
MotionCam Outdoor (PhOD) Jeweller
320×176 (default) Up to 10 seconds
640 × 352 Up to 17 seconds

Values provided that the hub works via Ethernet or 4G, and the signal strength between ReX 2 and the detector is three bars. If you use the Photo on Demand feature, there may be a delay of up to 3 seconds before the detector takes a photo.

If the detector is connected via a range extender, alarms are delivered in 0.3 seconds.

Copied

If the connection between the hub and ReX 2 is lost, all devices connected to the range extender also lose their connection with the hub.

Devices that have lost connection with the hub cannot transmit events, alarms, or photos to users and the security company monitoring station until connection is restored.

Thanks to OS Malevich, the range extender combines detectors into an autonomous group. If ReX 2 receives an alarm signal from the detector after the loss of communication, the range extender will activate the siren connected to it.

With OS Malevich 2.9 update, temporary deactivation of devices without removing them from the system has become available.

Deactivation may be necessary if the device is incorrectly installed or configured, loses connection with the hub, or has failed.

To temporarily deactivate a device, in the Ajax app:

  • Select a hub if you have several of them or if you are using the PRO app.
  • Go to the Devices menu.
  • Select the device from the list.
  • Go to its Settings .
  • Select the type of temporary deactivation:
    • Entirely — the device does not execute system commands or run automation scenarios, and the system ignores device alarms and other notifications.
    • Lid only — the system ignores the notifications on the detector’s tamper button triggering.
