Hub 2 Plus is a central device in the Ajax security system, which controls the operation of all connected devices and interacts with the user and the security company.
The hub reports the opening of doors, breaking of windows, threat of fire or flood, and automates routine actions using scenarios. If outsiders enter the secure room, Hub 2 Plus will send photos from MotionCam motion detectors and notify a security company patrol.
Hub 2 Plus central unit must be installed indoors only.
Hub 2 Plus needs Internet access to connect to the Ajax Cloud service. The central unit is connected to the Internet via Ethernet, Wi-Fi, and two SIM cards (2G/3G/4G).
Connecting to Ajax Cloud is necessary for configuring and managing the system through Ajax apps, transmitting notifications about alarms and events, as well as for updating OS Malevich. All data on Ajax Cloud is stored under multilevel protection, information is exchanged with the hub via an encrypted channel.
Connect all communication channels to ensure a more reliable connection with Ajax Cloud and to secure against interruptions in the work of telecom operators.
You can manage the security system and quickly respond to alarms and notifications through apps for iOS, Android, macOS, and Windows. The system allows you to choose of what events and how to notify the user: by push notifications, SMS, or calls.
If the system is connected to a security company, events and alarms will be transmitted to the monitoring station — directly and/or through Ajax Cloud.

The hub monitors the security system operation by communicating with connected devices via the Jeweller encrypted protocol. The communication range is up to 2000 m without obstacles (for example, walls, doors, inter-floor constructions). If the detector is triggered, the system raises the alarm in 0.15 seconds, activates the sirens, and notifies the central monitoring station of the security organization and the users.
If there is interference at the operating frequencies or when jamming is attempted, Ajax switches to a free radio frequency and sends notifications to the central monitoring station of the security organization and to system users.
Hub 2 Plus supports up to 200 Ajax devices connected, which protect against intrusion, fire, and flooding, as well as control electrical appliances automatically according to scenarios or manually from an app.
To send photos from MotionCam motion detector, a separate Wings radio protocol and a dedicated antenna are used. This ensures the delivery of visual alarm verification even with an unstable signal level and interruptions in communication.
Hub 2 Plus is running under a real-time operating system OS Malevich. Similar OS control spacecraft systems, ballistic missiles, and car brakes. OS Malevich expands the capabilities of the security system, automatically updating by air without user intervention.
Use scenarios to automate the security system and decrease the number of routine actions. Set up the security schedule, program actions of automation devices (Relay, WallSwitch, or Socket) in response to an alarm, pressing of the Button or by schedule. A scenario can be created remotely in the Ajax app.
The Ajax logo on the hub front lights up red, white, or green depending on the status of the power supply and Internet connection.
|At least two communication channels — Wi-Fi, Ethernet, or SIM card — are connected||Lights up white|
|A single communication channel is connected||Lights up green|
|The hub is not connected to the Internet or there is no connection with the Ajax Cloud server||Lights up red|
|No power||Lights up for 3 minutes, then blinks every 20 seconds. The color of the indicator depends on the number of the connected communication channels|
The security system is configured and controlled through Ajax apps. Ajax applications are available to professionals and users on iOS, Android, macOS, and Windows.
The settings of Ajax security system users and the parameters of connected devices are stored locally on the hub and are inextricably linked with it. Changing the hub administrator does not reset the settings of the connected devices.
To configure the system, install the Ajax app and create an account. One phone number and email address may be used to create only one Ajax account! There is no need to create a new account for each hub — one account can manage multiple hubs.
Your account can combine two roles: the administrator of one hub and the user of another hub.
When installing and using Hub 2 Plus, strictly adhere to the general electrical safety regulations for using electrical appliances, as well as the requirements of regulatory legal acts on electrical safety.
It is strictly forbidden to disassemble the device under voltage! Also, do not use the device with a damaged power cable.
Connecting to the network
- Remove the SmartBracket mounting panel by sliding it down with force. Avoid damaging the perforated part — it’s essential for the tamper activation in case of hub dismantling!
- Connect the power supply and Ethernet cables to the appropriate sockets, install SIM cards.
- Press and hold the power button for 3 seconds until the Ajax logo lights up. It takes about 2 minutes for the hub to upgrade to the latest firmware and connect to the Internet. The green or white logo color indicates that the hub is running and connected to Ajax Cloud.
If the Ethernet connection is not established automatically, disable proxy and MAC address filtration and activate DHCP in the router settings. The hub will automatically receive an IP address. After that, you will be able to set up a static IP address of the hub in the Ajax app.
- To connect to the cellular network, you need a micro SIM card with a disabled PIN code request (you can disable it using a mobile phone) and a sufficient amount on your account to pay for the services at your operator’s rates. If the hub does not connect to the cellular network, use Ethernet to configure the network parameters: roaming, APN access point, username, and password. Contact your telecom operator for support to find out these options.
Adding a hub to the Ajax app
- Turn on the hub and wait until the logo lights up green or white.
- Open the Ajax app. Give access to the requested system functions to fully use the capabilities of the Ajax app and not to miss alerts about alarms or events.
- Open the Add hub menu Select the way of registering: manually or step-by-step guidance. If you are setting the system up for the first time, use step-by-step guidance.
- Specify the name of the hub and scan the QR code located under the SmartBracket mounting panel or enter it manually.
- Wait until the hub is added. The linked hub will be displayed in the Devices tab .
After adding a hub to your account, you become the administrator of the device. Administrators can invite other users to the security system and determine their rights. Hub 2 Plus central unit can have up to 200 users.
Changing or removing the administrator does not reset the settings of the hub or connected devices.

Geofence — configuring reminders for arming/disarming the security system when crossing a specified area. The user location is determined using the smartphone GPS module.
Groups — group mode configuration. This allows you to:
- Manage the security modes for separate premises or groups of detectors.
For example, the office is armed while the cleaner works in the kitchen.
- Delimit access to control of security modes.
For example, the marketing department employees do not have access to the law office.
Security Schedule — arming/disarming the security system by the schedule.
Detection Zone Test — running the detection zone test for the connected detectors. The test determines the sufficient distance for the detectors to register alarms.
Jeweller — configuring the hub-detector ping interval. The settings determine how frequently the hub communicates with devices and how quickly the loss of connection is detected.
- Detector Ping Interval — the frequency of connected devices polling by the hub is setting in the range of 12 to 300 s (36 s by default)
- Number of undelivered packets to determine connection failure — a counter of undelivered packets (30 packets by default).
The time before raising the alarm by the communication loss between hub and device is calculated with the following formula:
Ping interval * (number of undelivered packets + 1 correction packet).
The shorter ping interval (in seconds) means faster delivery of the events between the hub and the connected devices; however, a short ping interval reduces the battery life. At the same time, alarms are transmitted immediately regardless of the ping interval.
We do not recommend reducing the default settings of the ping period and interval.
Note that the interval limits the maximum number of connected devices:
|12 s||39 devices|
|24 s||79 devices|
|36 s||119 devices|
|48 s||159 devices|
|72 s||200 devices|
Regardless of settings, the hub supports 10 connected sirens maximum!
Service — a group of service settings of the hub.
- Time zone — select the time zone in which the hub operates. It is used for scenarios that run on schedule. Therefore, before creating scenarios, set the correct time zone.
Connection settings for the hub and the Ajax Cloud service:
- Server Ping Interval. Frequency of sending pings from the hub to Ajax Cloud server. It is set in the range of 10 to 300 s. The recommended default value is 60 s.
- Connection Failure Alarm Delay. It is a delay to reduce the risk of a false alarm associated with the Ajax Cloud server connection loss. It is activated after 3 unsuccessful hub-server polls. The delay is set in the range of 30 to 600 s. The recommended default value is 300 s.
The time for generation of the message of the connection loss between the Ajax Cloud server and the hub is calculated as follows:
(Ping interval * 4) + Time filter
With the default settings, Ajax Cloud reports the hub loss in 7 minutes:
(30 s * 4) + 300 s = 7 min
- Disable alerts when the connection with the server is lost. Ajax apps can notify about the hub-server communication loss in two ways: with a standard push notification signal or with a siren sound (enabled by default). When the option is active, the notification comes with a standard push notification signal.
- LED Brightness. Adjustment of the brightness of the LED logo set in the range of 1 to 10. The default value is 10.
- System Integrity Check. If enabled, the hub checks the status of all devices before arming: battery charge, tampers, connection. If a problem is detected during the arming, the hub does not arm the system and displays a warning.
- Arming Permission (the option becomes active only after enabling the System Integrity Check). If enabled, the security system can be armed even if there is a malfunction.
To arm the security system with malfunctions through the Ajax app:
- Activate the armed mode — you will receive a notification with a list of malfunctions.
- Confirm arming by pressing Arm.
- Activate the armed mode — you will receive a refusal.
- Confirm the arming of the system by re-activating the armed mode within 30 s.
- Firmware Auto-Update. Configuring automatic OS Malevich firmware updates.

- If disabled, the system does not update automatically. If a new firmware version is available, the app will offer to update the OS Malevich.
FireProtect and FireProtect Plus fire detector configuration
- Interconnected FireProtect alarm. The function activates built-in sirens of all fire detectors if at least one of them is triggered. Sirens are activated within the hub-detector ping interval according to the Jeweller settings.
Interconnected alarms are supported by FireProtect and FireProtect Plus detectors with firmware versions 3.42 and higher. Please note that when you turn on the Interconnected Alarms, you cannot set the hub-detector ping interval (Jeweller settings) of more than 48 seconds.
- Ignore First Alarm. Alarm snooze function to check for the presence of smoke with fire detectors.
The option works as follows:
- The smoke alarm is triggered.
- The built-in 30 s timer inside the detector is activated.
- If after 30 seconds the detector still detects a threat, an alarm is sent to the hub.
This setting is recommended for premises with potential sources of false alarms, for example, if the device is installed in a place where dust or steam can get into the detector.
The settings for collecting and storing Ajax security system logs
- Hub System Logging. You can disable logs or select a transmission channel:
- No — logging is disabled
We do not recommend disabling logs as this information can help in the event of errors in the operation of the system!

Connection to the Central Monitoring Station (CMS) is implemented via the Contact ID or SIA protocol.
Prior to installing the hub, make sure that you have selected the optimal location and that it complies with the requirements of this manual! It is desirable that the hub be hidden from direct view.
Make sure that the communication between the hub and all connected devices is stable. If the signal strength is low (a single bar), we cannot guarantee a stable operation of the security system. Implement all potential measures to improve the signal quality! At the very least, relocate the hub as even repositioning by 20 cm can significantly improve the signal reception.
If low or unstable signal strength is still reported after relocation, use the ReX radio signal range extender.
When installing and using the device, follow the general electrical safety regulations for using electrical appliances, as well as the requirements of regulatory legal acts on electrical safety. It is strictly forbidden to disassemble the device under voltage! Do not use the device with a damaged power cable.
- Fix the SmartBracket mounting panel with bundled screws. When using other fasteners, make sure they do not damage or deform the panel.
We do not recommend using double-sided adhesive tape for installation: it can cause a hub to fall in case of an impact.
- Attach the hub to the mounting panel. After installation, check the tamper status in the Ajax app and then the quality of the panel fixation. You will receive a notification if an attempt is made to tear the hub off the surface or remove it from the mounting panel.
- Fix the hub on the SmartBracket panel with bundled screws.
Do not flip the hub when attaching vertically (for example, on a wall). When properly fixed, the Ajax logo can be read horizontally.
Do not place the hub:
- Outside the premises (outdoors).
- Nearby or inside any metal objects or mirrors causing attenuation and screening of the signal.
- In places with high radio interference level.
- Close to radio interference sources: less than 1 meter from the router and power cables.
- Inside any premises with the temperature and humidity beyond the range of permissible limits.
Check the operational capability of the Ajax security system on a regular basis. Clean the hub body from dust, spider webs and other contaminants as they appear. Use soft dry napkin suitable for equipment maintenance.
Do not use any substances containing alcohol, acetone, gasoline and other active solvents for cleaning the hub.
