AJAX Hub 2 (2G) / (4G) - User Manual

Hub 2 is the control panel of the security system and supports photo verification of alarms. It controls the operation of all connected devices and interacts with the user and the security service. The device is intended for indoor installation only.

The Hub central unit reports the opening of doors, the breaking of windows, the risk of fire or flooding and automates routine actions based on scenarios. When outsiders enter the secured room, Hub 2 sends photos from MotionCam / MotionCam Outdoor motion detectors and notifies a security patrol.

Hub 2 requires Internet access to connect to the Ajax Cloud service. The control panel has three communication channels: Ethernet and two 4G SIM cards.

Connect all communication channels to ensure a more reliable connection to the Ajax Cloud and avoid interruptions related to the work of telecom operators.

You can manage the security system through iOS, Android, macOS and Windows apps and respond to alarms and event notifications. The system allows you to choose which events and how the user should be notified: through push notifications, SMS or calls.

Hub 2 supports up to 100 connected Ajax devices that protect against burglary, fire or flooding and control electrical devices according to scenarios or via an app.

The hub controls the operation of the security system and all connected devices. To do this, it communicates with the system devices via two encrypted radio protocols:

1. Jeweller is a radio protocol used to transmit events and alarms from Ajax wireless detectors. The communication range is 2000 m in an open area (no walls, doors or intermediate floor structures).

Learn more about Jeweller

2. Wings is a wireless protocol used to transmit photos from MotionCam and MotionCam Outdoor detectors. The communication range is 1700 m in open space (no walls, doors or intermediate floor structures).

Learn more about Wings

Every time the detector is triggered, the system sounds an alarm in less than a second. In this case, the hub activates the sirens, starts the scenarios and notifies the security service monitoring center and all users.

Sabotage protection

Hub 2 has three communication channels: Ethernet and two SIM cards. This allows the system to connect to Ethernet and two cellular networks.

Wired Internet and cellular connections are maintained in parallel to ensure more stable communication. This also makes it possible to switch to another communication channel without delay if one of them fails.

In case of interference on Jeweller frequencies or attempts at sabotage, Ajax switches to a free radio frequency and sends notifications to the security service monitoring center and the system users.

What is security system sabotage?

Nobody can switch off the hub without being noticed, even if the system is disarmed. If an intruder tries to dismantle the device, this immediately triggers the tamper protection alarm. All users and the security service receive notifications about the triggering.

What is tamper protection?

The Hub checks the connection with the Ajax Cloud at regular intervals. The polling period is set in the Hub settings. When using the minimum settings, the server can notify users and the security service within 60 seconds after the connection is lost.

The hub has a backup battery with a runtime of 16 hours. This allows the system to continue working even if the power supply to the facility is interrupted. To extend the battery life or to connect the hub to 6 or 12 volt networks, use a 12V PSU and a 6V PSU .

OS Malevich

Hub 2 runs on the real-time operating system OS Malevich. The system is immune to viruses and cyber attacks.

OS Malevich updates installed over the air open up new possibilities for the Ajax security system. The update is automatic and takes only a few minutes if the security system is disarmed.

How to update OS Malevich

Connection to video surveillance

You can connect cameras and DVRs from Dahua, Hikvision, Safire, EZVIZ and Uniview to the Ajax security system. Thanks to the support of the RTSP protocol, it is possible to integrate third-party video surveillance devices. You can connect up to 25 video surveillance devices to the system.

Please note that the user and system settings as well as the settings of the connected devices are saved in the hub's memory. If the hub administrator changes, the settings of the connected devices will not be reset.

Connecting the Hub to the Ajax Cloud

Hub 2 requires Internet access to connect to the Ajax Cloud Service. This is necessary for running Ajax apps, remotely setting up and controlling the system, and receiving push notifications from users.

The central unit is connected via Ethernet and two 4G (LTE) SIM cards. We recommend that you connect all communication channels simultaneously to increase the stability and availability of the system.

To connect the Hub to Ajax Cloud:

1. Remove the SmartBracket mounting plate by pushing it down with force. Do not damage the perforated part as it is needed to trigger the anti-tamper alarm that protects the hub from dismantling.
   
2. Connect power and Ethernet cables to the appropriate sockets and install SIM cards.
   1 — Socket
   2 — Ethernet jack
   3, 4 — slots for installing micro SIM cards
3. Press and hold the power button for 3 seconds until the Ajax logo lights up.

It takes up to 2 minutes for the hub to connect to the Internet and update to the latest version of OS Malevich, provided there is a stable Internet connection. A green or white LED indicates that the hub is running and connected to the Ajax Cloud. Also remember that the hub must be connected to the external power supply to perform the update.

If the Ethernet connection fails

If an Ethernet connection cannot be established, disable proxy and МАС address filtering and enable DHCP in the router settings. The hub will receive an IP address automatically. After that, you can set up a static IP address for the hub in the Ajax app.

If the SIM card connection fails

To connect to the mobile network, you need a micro SIM card with the PIN code request disabled (you can deactivate it using a mobile phone) and sufficient funds on your account to pay for the services at your operator's rates.

If the hub cannot connect to the cellular network, configure the network parameters via Ethernet: roaming, APN access point, username and password. Contact your telecom operator to learn about these possibilities.

To change or remove the room image or name, go to the room settings by selecting Rooms from the Rooms menu. on the gear symbol press.

How to connect a detector or device to the hub

1. Log in to the Ajax app. Select the appropriate hub if you have multiple ones or if you are using a PRO Ajax app.
2. Open the Rooms menu on.
3. Open the room and select Add Device .
4. Name the device, scan its QR code (or enter it manually) and select a group (if group mode is enabled).
5. Click Add — the countdown for adding a device begins.
6. Follow the instructions in the app to connect the device.

To connect a device to the hub, the device must be within wireless range of the hub (in the same secured premises). If the connection fails, follow the instructions in the user manual for that device.

Notifications of events and alarms

The Ajax security system informs the user about alarms and events using three types of notifications: push notifications, SMS and phone calls. Notification settings can only be changed for registered users connected to the hub.

Hub 2 does not support calls and SMS using VoLTE (“Voice over LTE”) technology. Before purchasing a SIM card, please make sure that it only supports the GSM standard.

The hub does not notify users about the activation of opening detectors in disarmed mode - even if the doorbell function is enabled and configured. Only the sirens connected to the system report the opening.

How Ajax notifies users about messages

Choice of location

There are three main factors to consider when choosing a location:

• Jeweller signal strength,
• Wings signal strength,
• Strength of the mobile signal.

Place Hub 2 in a location with stable Jeweller and Wings signal strength of 2-3 bars with all connected devices (you can view the signal strength with each device in the list of states for the respective device in the Ajax app).

When choosing the installation location, consider the distance between the devices and the hub, as well as any obstacles between the devices that may hinder the passage of the radio signal: walls, false floors or large objects in the room.

To roughly calculate the signal strength at the installation location, use our wireless range calculator .

For correct and stable operation of the SIM cards installed in the hub, a cellular signal strength of 2-3 bars is required. If the signal strength is 0 or 1 bar, we cannot guarantee that all event notifications and alarms will be delivered via call, SMS or mobile internet.

Check the signal strength between the hub and all devices at the installation site. If the signal strength is low (a single bar), we cannot guarantee stable operation of the security system, because a device with low signal strength may lose connection with the hub.

If the signal strength is insufficient, try moving the device (hub or detector) to a different location, as moving it 20 cm can significantly improve signal reception. If repositioning the device does not work, try using a wireless repeater .

Hub 2 should be hidden from direct view to reduce the likelihood of tampering or interference. Please also note that the device is intended for indoor installation only.

Do not place Hub 2:

• outdoors. This may cause the device to not work properly.
• near metal objects or mirrors, for example in a metal cabinet. This can block and weaken the radio signal.
• in rooms where the temperature and humidity are outside the permissible range. This may cause the device to not function properly.
• near sources of radio interference: less than 1 meter from the router and power cables. This may result in loss of connection with the hub or devices connected to the wireless repeater.
• in locations with low or unstable signal strength. This may result in the connection to connected devices being lost.
• less than 1 meter from wireless Ajax devices. This may cause the connection to the detectors to be interrupted.

installation

Before installing the hub, make sure that you have chosen the optimal location and that it meets the requirements of this manual.

When installing and operating the device, the general safety regulations for the operation of electrical devices and the requirements of the legal provisions on electrical safety must be observed.

To install the hub:

1. Fasten the SmartBracket mounting plate using the screws provided. If you use other fastening devices, make sure that they do not damage or deform the plate. Use at least two fastening points when fastening. In order for the tamper protection alarm to be triggered when attempting to remove the device, the perforated corner of the SmartBracket must be fastened. Do not use double-sided tape to attach it. This may cause the hub to fall down or cause the device to fail after a blow or impact.
2. Connect the power cable, Ethernet cable and SIM cards to the hub. Turn on the device.
3. Secure the cables with a plastic retaining plate. This reduces the likelihood of sabotage as it is much more difficult to rip off a secured cable.
4. Slide the Hub 2 onto the mounting plate. After installation, check the tampering status in the Ajax app and then the quality of the plate attachment. You will receive a notification if there is an attempt to tear the Hub off the surface or remove it from the mounting plate.
5. Attach the hub to the SmartBracket mounting plate using the screws provided. Do not turn the hub upside down or sideways when mounting it vertically (e.g. on a wall). When the device is mounted correctly, the Ajax logo will be horizontal.

maintenance

Regularly check the functionality of the Ajax security system. The optimal check interval is three months. If necessary, clean the housing of dust, cobwebs and other contaminants. Use a soft and dry cloth suitable for device care.

Do not use substances containing alcohol, acetone, gasoline or other active solvents to clean the hub.
