Hub 2

Intelligent security control panel supporting detectors with photo verification

FAQ

You can connect any battery with the operating voltage of 4.2–16 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 from it 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.

* 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.

Copied

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

Copied

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.

12V 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.

Copied

Replace the standard 110/230V power supply unit with the 6V PSU for Hub 2/Hub 2 Plus.

How to install 6V PSU

Copied

No. Hub is designed for indoor installation.

Copied

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.

Divide the capacity of the external battery by the power consumption of the central panel.

Power consumption of the central panel depends mostly on active communication modules — the average values ​​are indicated in the table:

Central panel Active communication modules Average input current
Hub GSM 42 mA
Ethernet 80 mA
GSM+Ethernet 90 mA
Hub Plus GSM 35 mA
Ethernet 72 mA
GSM+Ethernet 93 mA
Wi-Fi 20 mA
Wi-Fi+GSM 42 mA
Wi-Fi+Ethernet 80 mA
Wi-Fi+GSM+Ethernet 96 mA
Hub 2 GSM 33 mA
Ethernet 80 mA
GSM+Ethernet 86 mA
Hub 2 Plus GSM 146 mA
Ethernet 200 mA
GSM+Ethernet 248 mA
Wi-Fi 98 mA
Wi-Fi+GSM 147 mA
Wi-Fi+Ethernet 213 mA
Wi-Fi+GSM+Ethernet 285 mA
ReX 20 mA

For instance, when connected to a 40A·h battery, Hub 2 — with active GSM module only — will operate approximately 1200 hours (40A·h / 0.033A).

Copied

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

Copied

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.

Copied

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 ReX.

Copied

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.

Copied

Our wireless data transmission protocol will continue to work at a GPRS rate of 0.5 kbit/s.

Copied

All Ajax detectors and devices can be connected to Hub 2 except another Ajax hubs and ocBridge Plus and uartBridge integration modules.

Copied

Correct operation of Hub 2 is guaranteed at a temperature ranging from -10°C to +40°C and humidity up to 75%.

Mounting Hub 2 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.

Copied

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.

Copied

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

Copied

Yes. The built-in battery of Hub 2 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.

Copied

Hub 2 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.

Copied

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

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 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.

Copied

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.

Copied

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.

Copied

Up to 9 security groups.
