Operating principle
Type4 Hub (4G) Jeweller monitors the system operation by communicating with added devices via the Jeweller encrypted protocol. The communication range is up to 2,000 m in an open space (for example, without walls, doors, or inter-floor constructions). If the device is triggered, the system immediately raises the alarm, runs scenarios, and notifies the monitoring company and system users about the incident.
The central unit is added to a space — a virtual entity that brings together various autonomous devices installed at the same facility.
OS Malevich
Type4 Hub (4G) Jeweller runs on OS Malevich, a real-time operating system protected against viruses and cyberattacks.
OS Malevich brings new features and functionality to the Ajax system through over-the-air updates. A PRO or a company with firmware update rights can start an update — when available — from the Type4 Hub (4G) Jeweller field in the Devices tab, or via the central unit states or settings. On-screen instructions help guide the user through the process.
The update takes up to 2 minutes and requires the system to be disarmed, free of active fire alarms, and connected to an external power supply.
Sabotage protection
Type4 Hub (4G) Jeweller has two communication channels for connecting to the Ajax Cloud server: Ethernet and a SIM card. This allows the device to work with multiple communication providers at once. If one channel becomes unavailable, the central unit automatically switches to another and notifies the monitoring station and system users.
If a jamming attempt is detected, the system switches to an idle radio frequency and sends notifications to the monitoring station and users.
No one can turn off the central unit unnoticed. If an intruder attempts to open the central unit enclosure, a tamper alarm is triggered immediately. An alarm notification is then sent to the monitoring company and all system users.
The central unit regularly checks its connection to Ajax Cloud. The ping interval is defined in the central unit settings. When the minimum interval is configured, the server can notify users and the monitoring company as soon as 60 seconds after the connection is lost.
The built-in backup battery ensures up to 15 hours of autonomous operation when the Ethernet connection is switched off. Due to this, the system continues to operate even if the power supply is cut off at the facility. To increase battery life or connect the central unit to a 6 V⎓ or 12–24 V⎓ grid, use a power supply unit: 6V PSU (type A) or 12–24V PSU (type A).
Video surveillance
Type4 Hub (4G) Jeweller is compatible with Ajax cameras and NVRs.
How to connect cameras to an Ajax system
You can calculate the number of cameras and NVRs that can be added to an Ajax space using Video device calculator.
Scenarios
Type4 Hub (4G) Jeweller supports 5 fire alarm scenarios for Type4 Line devices, allowing customization of the system’s response to specific triggers and alarms. These scenarios allow linking devices that can trigger the scenario with devices that can execute it.
Fire alarm scenarios include one general fire alarm scenario, which is present in the system by default, and multiple custom fire alarm scenarios defined by a user.
How to create and customize a fire alarm scenario
In addition to fire alarm scenarios, the Type4-certified system supports intrusion scenarios. If both types of scenarios are created in the system, they are organized into separate groups. Also, it is possible to open all scenarios of a specific type by selecting the corresponding tab.
Ajax account
To set up the system, install an Ajax app and log in to your account, or create a new one if you don’t have one. Don’t create a new account for each space, since one account can manage multiple security systems. Where necessary, you can configure separate access rights for each space. Changing the space admin, adding or removing users does not reset the settings of devices added to the space.
How to create the user account
Connecting the central unit to Ajax Cloud
Remove the SmartBracket mounting panel by shifting it down with force.
Connect the power supply and Ethernet cables to the appropriate sockets.
1 — Power cable socket.
2 — Ethernet cable socket.
3 — Slot for the micro SIM.
4 — Cable retainer clamp.Press and hold the power button for 2 seconds until the logo lights up. The central unit needs approximately 2 minutes to identify the available communication channels.
The bright green or white logo color indicates that the central unit is connected to Ajax Cloud.
If the Ethernet connection fails
If the Ethernet connection is not established, disable proxy and MAC address filtering and activate DHCP in the router settings. The central unit will automatically receive an IP address. After that, you can assign a static IP address to the central unit in an Ajax app.
If the SIM connection fails
Type4 Hub (4G) Jeweller is sold with the Ajax SIM card or a third-party SIM card.
To connect to the cellular network, you need to install a micro SIM card with a PIN code request disabled and sufficient funds on your account to pay for services according to the tariff plan. To disable the PIN code request, insert the SIM card into your phone.
If the central unit fails to connect to the cellular network, use Ethernet to configure the network parameters, such as roaming, APN access point, username, and password. To obtain these parameters, contact the support service of your mobile operator.

APN settings are applied only after a successful internet connection with new parameters is established. If the connection attempt fails, the central unit continues to work with the previous APN settings.
How to configure or change central unit APN settings
Mobile data usage. The menu contains information about mobile traffic used by an Ajax system, allowing you to reset the statistics and check the SIM card balance.
The data is calculated by the central unit and may differ from the operator’s statistics. This is because each mobile operator calculates incoming and outgoing traffic individually.
Incoming — the amount of data received by the central unit. Displayed in KB or MB.
Outgoing — the amount of data sent by the central unit. Displayed in KB or MB.
Reset statistics — allows resetting the statistics for incoming and outgoing traffic.
Check balance
USSD code. Enter the code used to check the balance in this field. For example, *111#. To send a request, tap Check balance after entering the code. The request result will be displayed under the balance check button.
Jeweller
Setting the polling period between the central unit and connected devices. The setting indicates how often the central unit communicates with the devices and how quickly a connection loss is detected.
Device ping interval, sec — the frequency of polling connected devices by the central unit; set in the range from 12 to 300 seconds. The default value is 36 seconds.
Number of missed pings to determine connection failure — a counter of undelivered packets. The default value is eight packets.
Do not reduce the default polling interval value unnecessarily.
The time after which the system sends a message about a connection loss between the central unit and the device is calculated with the following formula:
Device polling interval × Number of missed polls to determine connection failure
The shorter the polling period, the faster the central unit will know about the connected device events, and the faster the devices will receive central unit commands. Information about alarms and sabotage attempts is transmitted instantly, regardless of the polling interval. Reducing the polling period will affect the battery life of devices.
The polling interval limits the maximum number of connected devices:
Interval | Device limit |
12 s | 39 devices |
24 s | 79 devices |
36 s and more | 100 devices |
Send alarm when connected device goes offline — when enabled, events about connection loss are sent as alarms to all system users.
Fire alarm response time — defines how quickly notification devices are activated after a fire alarm is detected. There are two options:
Fast response — time from alarm detection to device activation is up to 3 s for sounders and up to 10 s for visual alarm devices.
Standard response — time from alarm detection to device activation is up to 6 s for sounders and up to 13 s for visual alarm devices.
Telephony settings
This setting is only available in Ajax PRO apps.
Telephony settings allow configuring the central unit to communicate with the monitoring station via the SIP protocol.
How to configure telephony settings for an Ajax central unit
In Ajax PRO Desktop, you can create and apply a telephony setting template to save time when configuring multiple systems.
How to create and apply setting templates in an Ajax system
Service
The central unit service settings are divided into two groups: general settings and advanced settings.
General settings
LED brightness
This setting allows configuring the central unit’s LED indicator brightness.
Firmware update
The menu contains the central unit firmware update settings.
Check for new version allows manually checking and installing firmware updates when they are available or assigned to the central unit. This option is available only when the Firmware auto-update setting is enabled.
If the central unit firmware is outdated, an error may occur when you add a device to the central unit. In this case, the system will prompt you to open the Firmware update section in the Service settings and check for a new firmware version. If it is available, you can proceed with an on-demand firmware update.
Hub system logging
This setting allows selecting the central unit log transmission channel or disabling log recording:
Off — logging is disabled.
Ethernet — system logs are transmitted via the Ethernet channel.
Cellular for 10 minutes — note that the cellular logging significantly increases mobile data usage.
Logs are files containing information about system operation. Do not disable the logs, as this information may be helpful in case of system errors.
Delaying notifications of external power loss
This setting allows configuring a delay time for sending an external power loss notification.
You can select the delay time from 1 minute to 1 hour in 1-minute increments.
“While hub offline” event amount
In case of server connection failure, events are recorded in the central unit buffer and will be delivered to Ajax apps once the connection is restored.
This setting allows choosing the number of recent events that the central unit will send to Ajax apps after returning to normal operation.
You can select from 100 (default value) to 1,000 events with an increment of 50 events.
Advanced settings
Server connection
These settings allow configuring the connection between the central unit and the Ajax Cloud server:
Delay of server connection failure alarm. The delay is necessary to reduce the risk of false notifications of a connection loss with the Ajax Cloud server. It is activated after three unsuccessful central unit–server polls. The delay can be set in the range from 30 to 600 s. The recommended default value is 300 s.
Hub-server polling interval, sec. Indicates the frequency of polling requests from the central unit to the Ajax Cloud server. It can be set in the range from 10 to 300 s. The recommended default value is 60 s.
The time before the central unit sends a notification of a connection loss with the Ajax Cloud server is calculated with the following formula:
(Polling interval × 3) + Time filter.
With the default settings, Ajax Cloud detects a connection loss with the central unit within 8 minutes:
(60 s * 3) + 300 s = 8 min.
Get notified of server connection loss without alarm. Ajax apps can notify users of a connection loss between the central unit and the server in two ways: with a standard push notification or with a siren sound (enabled by default). When the option is active, the notification comes as a standard push.
Notify of connection loss over channels. An Ajax system can notify both users and the monitoring company of a connection loss between the central unit and the Ajax Cloud server even via one of the communication channels.
In the menu, you can select the communication channels through which the system will notify users of a connection loss, as well as the transmission delay for such notifications.
Loss notification delay — the delay time before the system sends a connection loss notification via one of the communication channels. The delay can be set in the range from 3 to 30 minutes.
The time for the system to send a connection loss notification via one of the communication channels is calculated with the following formula:
(Polling interval × 3) + Time filter + Notification delay.

Selecting the installation site
When choosing where to place Type4 Hub (4G) Jeweller, consider the parameters that affect its operation:
Jeweller signal strength.
The distance between the fire alarm central unit and devices.
Install the central unit on a vertical surface. This will ensure proper tamper button response if someone attempts to remove the device.
Choose a location where the central unit can access all available communication channels: Ethernet and a SIM card. Ensure that the cellular signal at the installation site is stable and reaches at least 2–3 bars. Correct device operation is not guaranteed if the cellular signal is weak.
When selecting the installation site, consider the distance between the central unit and devices, as well as any obstacles that may interfere with radio signal transmission, such as walls, intermediate floors, or large objects in the room.
To roughly calculate the signal strength at the place of installation of devices, use our radio communication range calculator. Note that if the signal strength is excellent, the device can automatically adjust the power of radio transmission to reduce power consumption and radio interference.
Run the Jeweller signal strength test before final installation. The test checks the signal strength at the device’s maximum transmission power. To comply with Type4 requirements, the signal strength between the device and the central unit must be at least two bars. With a signal strength of one or zero bars during the test, we do not guarantee stable operation of the system.
If the system has devices with signal strength of 1 or 0 bars, consider relocating the central unit or device. If this is not possible or the device still has low or unstable signal strength after being moved, use Type4 ReX Jeweller.
Where not to install the device
Outdoors. This could result in device failure.
Near metal objects and mirrors. They can cause attenuation or shielding of the radio signal. This could result in the loss of connection between the central unit and Ajax devices.
In places with high levels of radio interference. This could result in the loss of connection between the central unit and Ajax devices or false notifications about security system jamming.
Less than 1 meter away from the router and power cables. This could result in the loss of connection between the central unit and devices.
Less than 1 meter away from Jeweller devices. This could result in the loss of connection between the central unit and these devices.
In places where the central unit will have a signal strength of 1 or 0 bars with connected devices. This could result in the loss of connection between the central unit and these devices.
Inside premises with temperature and humidity beyond the permissible limits. This could result in a failure of the central unit.
In places with no cellular signal or 1 bar signal strength. We do not guarantee the correct operation of the device with a low cellular signal strength.
Installation
During installation and operation of the Ajax system, adhere to the rules and requirements of regulatory legal acts on electrical safety. Do not disassemble the device while it is energized or use it with a damaged power cable. Observe the safety procedures and the rules for electrical installation work when connecting the central unit.
