Wireless control panel. Connectable via Ethernet and SIM card (LTE)
The hub is the central device of the Ajax system. The hub model affects some of the system’s functionality.
The following factors affect the amount of cellular data used by the hub:
You can use an empty space for 180 days from the date the space was created or from the date the last device was deleted. After this period, an empty space will be deleted.
To avoid space configuration loss, the system sends a notification after 173 days from the date the space was created or from the date the last device was deleted.
The system will delete the empty space even if it is armed. The user can delete the empty space only when the system is disarmed. When the space is deleted (automatically or manually), its events are also deleted.
You can create and use a limited number of empty spaces. Ajax space is empty when no Ajax hub, Ajax camera, Ajax NVR video recorder, or Yale smart lock is added.
You can create and use:
If a space is empty, you cannot arm it or use the panic button in Ajax apps.
You can still create and use an unlimited number of spaces with devices.
Yes, you can delete the offline hub from armed space. This can be helpful if the hub fails while the system is armed and there is no way to replace the hub using data transfer. If the hub is removed from the space, the user can continue to use Ajax cameras, Ajax NVR video recorder, and Yale smart lock added to the space.
Admin or Installer with system configuration rights can delete the offline hub from armed space.
To do this, in the Ajax apps:
tab and select the hub you want to delete.
.You can delete the offline hub from armed space if this hub is not connected to the monitoring station.
No, when the space is deleted (manually or automatically), its events are also deleted. You cannot restore it.

No, you need an Ajax hub to connect a system to monitoring software.
Other features do not depend on the adding of a hub to the space, including the Control and Rooms tabs and quick access to automation devices.
No, you only need to update your app:
Features will remain the same, including the Control and Rooms tabs and quick access to automation devices.
No such option is provided for. Deleting security system events is prohibited under the requirements of EN 50131.
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.
menu.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/Hub Plus/ReX.
The number of scenarios by alarm, Button press, and by schedule depends on the hardware capabilities of the hub: Hub (2G) Jeweller and Hub (4G) Jeweller support up to 5 scenarios, Hub 2 Jeweller and Hub Hybrid — up to 32, Hub Plus Jeweller and Hub 2 Plus Jeweller — up to 64.
At the same time, only one reaction to arming/disarming for every automation device can be created. Scenarios of this type are not included in the general limit of the scenarios.
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 (2G) Jeweller, Hub (4G) Jeweller and Hub Plus Jeweller 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.
When hub loses the connection with the server, Ajax apps can notify the users using a standard push-notification sound or a siren sound (enabled by default).
To disable the siren sound when hub loses the connection with the server in the Ajax app:
→ Hub → Settings → Service).
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.
The SIM card number can be determined using two methods:
→ Hub → Settings → Cellular). The menu opposite the SIM card will display its number.
The functioning of the feature depends on whether the manufacturer recorded the number-related information on the SIM card
→ Hub → Settings → Cellular) and select the SIM card. In the USSD-request field, enter the number check code (provided by your operator) and click Check Balance. After the request is executed, the SIM card number will be displayed under the Check Balance button.The number of ReX range extenders connected to the Ajax security system depends on the hub model:
| Hub | 1 |
| Hub Plus | 5 |
| Hub 2 (2G) | 5 |
| Hub 2 (4G) | 5 |
| Hub 2 Plus | 5 |
| Hub Hybrid (2G) | 5 |
| Hub Hybrid (4G) | 5 |
Only hubs on OS Malevich 2.8 and higher support the connection of several ReX.
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).
You can significantly expand the coverage area of the Ajax radio network using several ReX in the security system. However, keep in mind that ReX can only be connected directly to the hub and connecting one range extender to another is not supported.
The number of ReX connected to the security system depends on the hub model.
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.
Tamper is a miniature button on the device board. It reports an alarm in case of opening the device enclosure, removing the device from the mounting panel, or detaching it from the surface.
The tamper status is displayed in Ajax apps, in the Enclosure section in the states of each device. When the body status is Open, a fault symbol appears on the device icon.
The maximum distance between the hub and the device can reach 2,000 meters in an open space.
Walls, ceilings, and other structures that interfere with the radio signal to get through can significantly reduce the range. In this case, maximum distance mainly depends on the structures’ material, thickness, and arrangement.
You can expand the coverage area of Ajax security systems with the help of radio signal range extenders
The Hub (2G) will be receiving new software features as long as its electronic components can support their functioning. Once its development potential is exhausted, the software will be updated to ensure compatibility with the Ajax server and applications.
The aim of developing Ajax is to provide current and future owners of our systems with greater opportunities. New products of the Ajax range will be operated under the control of Hub (2G) and Hub Plus if such support can be ensured by updating the control panels software. In the future, the capacities of the new devices might require other hardware components of the central unit, and a new control panel will be needed to run them.
The Ajax control panels have different purposes. The standard Hub (2G) provides a basic set of features ensuring integrated security of an apartment, a house, a store, or an office. The advanced Hub 2 Plus has unique communication capacities: the control panel is equipped with Wi-Fi and Ethernet modules and two 2G / 3G SIM card slots, and it can ensure security of large facilities, which is attributed to its 150 detectors, 25 groups, 99 users, and 50 cameras, works up to 16 hours from backup battery. For the time being, less than 50% of the Hub 2 Plus hardware capabilities are utilized. Future software updates will uncover the full potential of the device.
We are developing Ajax to provide our customers with more opportunities and increase the level of security and resilience of the system. This process cannot affect negatively the user experience and limit the existing opportunities. The central units of all generations will be supported by the Ajax servers and applications.
The type of SIM card used is Micro-SIM.
SIM-card must be inserted with the front part (with the operator’s label) towards the cavity marked with the Hub:
In order to allow automatic updating of the firmware of the Hub, select the Hub in the device list, go to the settings , select Service and turn on the option Automatic software update.
Auto-Update is turn on by default.
Press the power button (the Ajax logo will turn off) and hold for 30 seconds, until the logo is flashing red. This will remove all detector connections, room configurations, and user setting. User accounts will remain connected to the system.
Most likely, several users are receiving SMS alerts. For example, if three people receive SMS alerts, then each notification is sent out three times.
No, Ajax Hub can work without port forwarding.
Yes, as long as the test shows a good enough radio communication. But you will still need to secure the Hub on the table with the provided screws. This is required to ensure the alarm will work if an intruder tries to dismantle Ajax Hub.
To make SIM card work properly, please do the following steps:
Detectors’ LED indication turns only in armed mode in case of alarm. While the detector is disarmed, it won’t blink with the LED in case of actuation.
The functioning of the detector may be checked using the Detection Zone Test
Check if both LEDs are lit on the Ethernet port when the cable is connected. If they aren’t, connect another Ethernet cable. If they are, check your router settings. It should be set to DHCP mode.
The system uses our own two-way protocol, Jeweller. The protocol allows Ajax Hub to monitor securely all network devices up to 2,000 meters away in open space, helps to identify detector failures and radio jamming, and carries out radio and detection zone tests.
By default, Ajax apps notify about the loss of hub connection with the Ajax Cloud server when there is no connection via all the connection channels: Ethernet, Wi-Fi, cellular (connection channels depend on the hub model).
Ajax apps can notify about such an event in two ways: with a push notification, with a siren sound (enabled by default).
To be notified about the connection loss, even on one of the channels, in the Ajax app:
menu and select the hub.
in the upper right corner of the screen.Ajax’s security system can use the following connection channels with the Ajax Cloud server and the security company: Ethernet, Wi-Fi, or cellular. The number and the type of connection channels depends on the hub model. If connection is lost on any of the channels, the hub will instantly switch to another channel available.
When several channels are connected to the hub, priority is given to the faster ones: Ethernet and Wi-Fi (connection channels depend on the hub model). Cellular is used as a backup channel and consumes minimum of traffic. It is impossible to change this priority.
You will receive a push-notification. If you’ve activated SMS alerts, you will receive an SMS alert.
Yes. The battery inside the hub will provide for up to 16 hours of system operation. In the case of switching to backup power, a push-notification and an SMS-message will be sent.
Also hub can be connected to 12V⎓ sources.
The Ajax security system supports connection to Ajax Cloud via all connection channels at once: Ethernet, Wi-Fi, and cellular (channels depend on the hub model). This is necessary to ensure that in case of loss of connection on any of the channels, the hub instantly switches to another channel.
Most of the data is transferred via Ethernet and Wi-Fi, and fewer data is transferred via cellular. It is impossible to change this priority.
The hub update does not exceed 1 megabyte.
The user identifier is a unique number which is assigned by the hub to the specific user being added.
If the user has several hubs, they will be assigned their own unique number in each hub
Your own user identifier can be found in the profile settings (Hub → Settings → User settings ).
Your identifier and combinations for using the keypad personal password are displayed in the settings menu.
Ajax encrypts data using its own proprietary floating key protocol. This protocol is resistant to breaking: even with the power of a supercomputer, it will take years to break the key by a Brute-force search.
Let’s assume a situation where an attacker was able to compromise the key. In this case, the protocol is still protected by the session counter: a new encryption key is generated within each device-hub communication session.
Even if an attacker bypasses the session counter, he will be stopped by device authentication: a secure communication channel is created between the detector and the hub, followed by an ID check.
Each device has a personal ID by which the hub recognizes it.
If the device fails the ID check, the hub will ignore its commands.
Moreover, the hub will detect the loss of the Ajax device that the attackers want to replace with the fake one. The detection time depends on the device type: 3 seconds for wired Ajax devices and the time set in Jeweller settings — for wireless ones. The lost connection notification will be sent to the security company and system users.
To delete a group:
→ Groups)..At the moment, it is impossible to delete all groups from the hub. To completely remove all groups, the hub must be returned to the factory settings!
To disable the group mode, go to groups settings (Hub → Settings → Groups) and deactivate the group mode.
The ID of the group is a number of the group, which is necessary for arm separate groups from the keyboard.
The group number (ID) is displayed in the group settings (Hub → Settings → Groups).
In hubs with the firmware version OS Malevich 2.6 and latest hub administrator can limit the user’s access to the following functionality:
All these settings you can find in the user’s settings (Hub → → Users → User settings ).
The rights to the group, viewing notifications, devices and rooms can only be removed from the user account!
The second IP address is a backup in case of direct connection to the Central Monitoring Station (CMS).
If the main IP address is not available, the hub uses the second IP address to send events.
When the hub communication with the server fails (the Ajax logo lights red), the security system continues autonomous operation responding to all events, executing the enabled scripts, and activating the siren when applicable.
The events during the communication failure are recorded in the hub buffer and are delivered to the Ajax applications when communication with the server is restored.
The number of events stored in the hub buffer can be set in the hub settings. You can select from 100 (by default) to 1000 events in increments of 50 events. This feature is available for hubs with OS Malevich firmware version 2.25 and later (except for Hub (2G) Jeweller model). For hubs with firmware version up to OS Malevich 2.17, the buffer can contain no more than 130 events. Except for the Hub (2G) Jeweller, it can store up to 64 events.
Since the Ajax applications communicate with the hub via the server, you cannot operate the hub via applications in the case of Internet connection failure.
If the hub connection to cellular network is active, it continues calling and sending SMS to users — if these notification methods are enabled.
The direct connection (Monitoring Station tab) is the channel used to transmit hub events directly to the Central Monitoring Station (CMS) of the security provider, bypassing our server.
When direct connection is used, all events are communicated directly to the security company’s central monitoring station without affecting the functioning of the Ajax apps. If the direct connection is lost for any reason, the server acts as a redundant communication channel.
By default, the hub is set to a hub–detector ping interval of 36 seconds and 30 undeliverable data packets to consider the device lost. With these settings, the hub will detect the loss of the detector in 18 minutes.
To reduce this time, go to the hub settings in the Jeweller section and change the settings. The minimum time for detecting loss of connection with the device is 36 seconds (3 polls of 12 seconds each).
The time before raising the alarm by the communication loss between hub and device is calculated with the following formula:
Detector Ping Interval × Number of missed pings to determine connection failure
Note that with the minimum ping interval, short-term interference can lead to loss of connection with the device. Therefore, set the minimum values only if it is critically important to promptly inform about events in the system.
At the moment, such an opportunity is not provided, since the equipment of other manufacturers uses other frequencies and communication protocols with the control panels.
The automatic update is optional and can be disabled. To do this, go to the service settings of the hub (Devices → Hub → Settings → Service) and disable Firmware Auto-Update.
Remove the SIM card of the previous operator from the hub and replace it with the SIM card of the new mobile operator. For more details on installing a SIM card in the hub, please refer to the section Connecting the hub to Ajax Cloud in the hub user manual.
Before changing the SIM card, check the tariff, tariff conditions, and APN data with the telecommunications operator whose SIM card you plan to use.
After changing the SIM card, check the cellular network connection parameters in the Ajax app. If necessary, make changes to the SIM card settings.
The number to top up is on the plastic card holder of the SIM card, included in the box. Top up like any other mobile phone account.
You need to click on the Number field, enter the balance check USSD code (available from the mobile phone service provider).
After entering the number, click “Check balance”. It takes about a minute to complete the request. After the query is executed, you will see the status of the SIM card account.
The hub consumes mobile traffic regularly to check the functioning of the GSM channel and its availability as a backup communication channel.
The volume data depends on the settings and the number of devices assigned to the Hub. Working in the regular mode without alarms, the Hub uses up to 10 Megabytes per day.
The loop (zone) number is required to describe all devices connected to the hub when adding a protected facility to the security company monitoring station.
The number is assigned when adding a device to the hub. The first added device has the first loop (zone) number. After removing the device from the system, its number becomes available. This number can be assigned to the next device to be added to the system.
The loop (zone) number is available in the states of each device in the Ajax app:
Monitoring Station — is a function used by security companies to configure a Direct Connection to the Hub with the CMS. When the Direct Connection is enabled, the Hub will send events directly to the IP and the port specified in the settings (without the participation of our server).
The firmware version can be found in the device states in the Ajax app.

Devices → Hub → Settings → Cellular
It is possible. In the Ajax Security System application, on average, you can add up to 50 Hubs. Such an amount can withstand the average user’s smartphone, the number of the attached Hubs is not limited and depends only on the phone characteristics.
However, we do not recommend using the Ajax Security System application to monitor a large number of objects, for these purposes there is a solution for professional installers, Ajax PRO: Tool For Engineers.
The detection time of communication failure with the server depends on two parameters in the Hub settings (Hub → Settings → Service):
The connection delay is activated after 4 failed pings.
The time until the message about the loss of communication between the Hub and the server is generated is calculated by the formula:
(Ping interval * 3) + Connection Delay
With the default settings, the server records the loss of the hub after 8 minutes:
(60 s * 3) + 300 s = 8 minutes
Reducing the time of registration the loss of communication with the Hub can be achieved by reducing the values of the ping interval and the connection delay. But this increases the likelihood of a false event of loss of connection with an unstable Internet connection.
Go to the Devices tab , select the device you want to check.
