ReX

Intelligent radio signal range extender

FAQ

The list of ReX compatible devices:

Security detectors
Fire detectors
Leakage detectors
Automation devices
Control devices
Sirens
Integration modules

ReX is not compatible with ocBridge Plus, uartBridge and MotionCam.

In order to assign device to hub:

  1. Go to ReX Settings in the Ajax application (Devices ReX Settings ).
  2. Click Pair with device.
  3. Uncheck the devices that should directly operate via the hub.
  4. Click Back to save the settings.

In order to assign device to ReX:

  1. Go to ReX Settings in the Ajax application (Devices ReX Settings ).
  2. Click Pair with device.
  3. Select the devices that should operate via the range extender.
  4. Click Back to save the settings.

The devices operating via the range extender are labeled with RE icons in the application’s list of hub devices. In addition, the latter is also specified in the device menu, in the Operates via ReX field.

ReX is designed to operate on a power supply of 110V–240V AC, 50/60 Hz. In the event of a power failure, ReX is fitted with a backup battery that ensures up to 35 hours of operation of the range extender.

Only one ReX range extender can be connected to the hub featuring OS Malevich 2.7 firmware version.

Alarms are communicated within 0.3 seconds.

In the event of a loss of connection between the hub and ReX, all devices connected to the range extender also lose connection with the hub.

By copying the system information from the hub, ReX creates an autonomous group of devices and responds to events instantaneously. If ReX continues to communicate with the connected devices when the connection with the hub is lost, ReX assumes the role of the control panel: it will receive an alarm signal from the detector and activate the siren.

Users can manage the security modes of ReX and of the devices connected to the range extender only after the connection between the range extender and the hub is restored.

ReX functions at a distance of up to 1,800 meters from the hub and can double the radio communication range between the Ajax devices and the hub.

The communication range between ReX and a paired device is limited by the radio signal range of the device (the relevant parameter is indicated in the device’s specifications on the website and in the User Manual).

No. ReX expands the security system’s radio communication coverage, thereby enabling the installation of Ajax devices at greater distances from the hub or in locations where a reliable signal reception from the control panel cannot be ensured.

ReX expands the hub’s radio communication coverage.

ReX receives hub signals and transmits them to the devices connected to the range extender. It also transmits signals received from the devices to the hub. Two-sided connection is provided by the Cargo protocol operating over the Jeweller radio protocol.

Unlike regular range extenders that only re-broadcast signals, ReX controls the functioning of the security system devices. By copying the system information from the hub, ReX creates an autonomous group of devices and responds to events instantaneously. If the hub disconnects from the network for whatever reason, ReX receives an alarm signal from the detector and activates the siren.

ReX does not increase the number of devices connected to the hub!

 

Tamper is a miniature button on the device board. It is released when the lid is opened as well as a result of an attempt to unfasten and/or lift the device from the surface, which initiates an event.

When the tamper is released, the Hub sends push notifications and SMS messages (if this type of notification is enabled) to all users of the security system and also communicates the event to the central monitoring station of the security company.

If the tamper is released, Ajax applications display the Open status in the Lid field of the device menu. In addition, a malfunction badge appears on the device icon.

 

By default, the Hub is set to ping detectors every 36 seconds and to signal an alert after 30 undelivered pings. Under these settings, it will take about 18 minutes for the system to recognize a communication failure. You can adjust these settings by opening the app, going to the Hub Settings →Jeweller.

The loop (zone) number is required to add a guarded facility to the CMS along with descriptions of all devices connected to the hub.

The loop (zone) number is available in the settings after activating the group mode in the Ajax application:

  1. Hub Settings Groups

Having selected a group, you will see a list of its devices. Each device has a Device No. (or DeviceIndex in Ajax PRO Desktop) that corresponds to the loop (zone) number. A number is assigned when a device is attached to the Hub. The first added device has the first loop (zone) number.

After a device or a detector is removed, its number will be assigned to the next added device. However, the numbering of other devices will not change.

In the Ajax app, select the «Devices» tab . Information about the firmware version and device ID is located at the very bottom of the tab with the device parameters.
