Hub 2 (2G) / (4G)

The detector only works with Hub Plus, Hub 2 , Hub Hybrid and Hub 2 Plus. Connection to the Hub is not provided!

You can connect any battery with the operating voltage of 4.2–10 V to the hub using 6V PSU.

We recommend using zinc-air alkaline batteries for extended autonomous operation. Before connecting such a battery, remove the stickers or open the air shutoff valves. If possible, leave the battery with access to the air for up to 2 hours. This will trigger a chemical reaction inside the battery and ensure proper functioning.

Below is a list of recommended batteries with guaranteed compatibility.

List of recommended batteries

* The battery lifetime was calculated with Jeweller’s default settings (hub–detector polling interval of 36 seconds), average temperature of 25℃, and 4 detectors connected to the hub.

If you want to use another battery, you can calculate the approximate time by this link.

Hubs can only work with one power supply: standard or alternative (6V PSU, 12V PSU or 12-24V PSU).

With 6V PSU the hub can run on an external battery for years — without being connected to the facility’s electric grid — and be ready to protect run-down or empty premises, as well as buildings under construction against burglars, vandals and unauthorized occupants.

12-24V PSU is used to connect the hub to the low-voltage network of a car, trailer, yacht or to power it from an external battery/power supply.

Replace the standard 110/230V power supply unit with the 6V PSU.

How to install 6V PSU

No. The hub is designed for indoor installation, operates in temperatures from -10°C to + 40 °C, and relative humidity up to 75%.

Outdoor installation may damage the device or lead to its malfunction.

The hub identifier or its serial number is the first 8 characters under the QR code of the hub.

You can find identifier of the hub under the SmartBracket mount, on the box label, as well as in the hub states in the Ajax application.

Replace the standard 110/230 V~ power supply unit with 12V PSU for Hub 2/ReX 2.

This is a hardware limitation. To support visual alarm verification, Hub 2 is equipped with two radio modules. The first module uses the Jeweller radio protocol, which is responsible for communication between the hub and Ajax security devices, as well as for prompt delivery of alarms. The second radio module is reserved for the new Wings radio protocol, transmitting images of MotionCam motion detector.

Hub and Hub Plus are equipped with one radio module and communicate with Ajax security devices via the Jeweller radio protocol only.

OS Malevich 2.9 update has added the ability to transfer data from one hub to another without reconfiguring the system, adding users or devices.

To use the function, go to the Data Import menu in the settings of the hub to which you want to transfer data, and follow the on-screen instructions. To transfer data, OS Malevich of both hubs must be 2.9 or higher.

Hubs don’t have a Radio Signal Extender operation mode. If you need to expand the coverage of your security radio network, use radio signal extender.

We do not provide hub exchange services for a new model or buyback.

At the same time, we guarantee that the hub you purchased will continue to work as an Ajax security system control device: it will retain the server and applications support, as well as compatibility with Ajax devices that can be delivered by OS Malevich update.

The hub can operate with a 2G network connection, sending all alarms, events and Photo in Case of Alarm (depends on the hub model) to the users and the security company’s Central Monitoring Station.

The minimum connection speed required for the hub operation is 0.5 kbps.

All Ajax detectors and devices can be connected to a hub except another Ajax hubs and ocBridge Plus and uartBridge integration modules.

Please note that Hub 2 (2G) and Hub 2 (4G) are not compatible with wired Fibra products.

Correct operation of a hub is guaranteed at a temperature ranging from -10°C to +40°C and humidity up to 75%.

Mounting a hub inside rooms with a different temperature mode can lead to loss of communication with Ajax devices, and in the worst case — to failure of the device. Note, that the battery life of the hub can be significantly reduced at low temperatures.

Yes, the Ajax security system can operate when only one of the communication channels is used.

Nevertheless, we recommend connecting all communication channels as one channel may stop functioning. For example, if you run out of balance on your account or due to a malfunction of the operator’s equipment.

Hub 2 (2G) uses only 2G technology to transfer data via the mobile internet connection.

Hub 2 (4G) supports 3G and 4G (LTE) networks.

Yes. The built-in battery of a hub provides up to 16 hours of battery life.

In the case of switching to a backup power source, a corresponding notification is sent to the user and the security company.

To connect the hub to a 12 V backup power source and increase the battery life, replace the pre-installed power supply unit with a 12V PSU.

To connect the hub to portable batteries, use a 6V PSU power supply unit.

Hub 2 (2G) uses 3 communication channels for transmission of alarms to users and the monitoring station of a security organization: Ethernet (main communication channel) and two 2G SIM cards (backup channel). If one of the channels is temporarily unavailable, the system switches to the other one automatically and without delay.

You can install a SIM card of any operator supporting 2G internet into Hub 2 (2G).

Prior to installing the SIM card into the hub, disable the PIN code request in the settings menu (in order to do this, you need to insert the card into a phone). Furthermore, your mobile account must have a positive balance or bonus megabytes of traffic.

We recommend inserting two SIM cards into Hub 2 (2G) at the same time as one SIM card may stop functioning if you run out of balance or if a failure occurs on the provider’s side.

It is possible under the following conditions:

• hub signal strength with all detectors and devices is 2-3 bars
• reliable reception of the GSM signal

It is also recommended to attach the hub to the table with screws. Otherwise, if you try to demount the device, the tamper will not be triggered and you will not receive a notification.

The communication range between the hub and the device is limited by the radio signal range of the device (indicated in the specifications of the device page on the website and in the User Manual). The maximum communication range with Ajax devices is 2000 meters without obstacles.

Up to 9 security groups.

Up to 25 cameras or DVRs.

Up to 50 security system users (regular and PRO).

Up to 100 detectors or Ajax devices.

No more than 10 sirens HomeSiren or StreetSiren can be connected to the hub!

Hub 2 (2G) represents an intelligent security system control panel that supports detectors featuring photo verification of alarms.

*Scenarios of reaction to changing the security mode are not taken into account in the total limit of the hub scenarios

The firmware version can 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. The firmware version information is located on the status screen at the bottom.
