Operating principle
Type4 Fire Hub Jeweller is the fire alarm central unit of an Ajax system, designed for comprehensive management of fire safety systems. It also supports video surveillance and automation devices, making it a unified solution for protecting commercial and municipal sites. The central unit controls the operation of connected devices and indicates the current state of the fire safety system.
The central unit is added to a space — a virtual entity that brings together various autonomous devices installed at the same facility.
You can connect up to 200 wireless Ajax devices to Type4 Fire Hub Jeweller. To monitor the operation of all connected devices, the central unit communicates with them using two encrypted protocols:
1. Jeweller is a radio protocol for transmitting events and alarms from Ajax wireless devices. The communication range is up to 1,800 m in open space, without obstacles such as walls, doors, or inter-floor structures.
2. Wings is a radio protocol for transmitting large data packets. The communication range is also up to 1,800 m in open space.
If a fire detector is triggered, the system raises an alarm within three seconds. In this case, the central unit activates the sirens, runs scenarios, and alerts the monitoring station and all users.
Fire protection
Type4 Fire Hub Jeweller is fully compliant with key fire detection and fire alarm system standards, specifically Type4. It allows building wireless fire detection and alarm systems in commercial and municipal facilities.
Ajax devices from the Type4 Line connected to the central unit are assigned to one of 40 Fire zones. When a fire is detected in any zone or an Ajax manual call point is pressed, all Ajax Type4 sounders and visual alarm devices (VADs) across the facility raise an alarm.
The central unit display shows complete incident information: the cause of the alarm, the time it started, and where (zone, room, location), along with the last activated zone and the total number of zones in the fire alarm state.
Thanks to its intuitive interface and detailed LED indication, users can quickly respond to alarms, locate the fire, or activate the evacuation manually.
Users with the appropriate rights and access level can control the fire alarm from the central unit display or via Ajax apps: Control 
tab → tap the 
icon. The Control tab provides the following actions:
- Start evacuation — activates sounders and VADs;
- Stop evacuation — silences sounders and VADs;
- Indication test — run the central unit indication test.
The alarm can be reset only after all fire signals in the system have been cleared.
Event center
Ajax apps keep a detailed log of alarms, events, and user actions. The central unit display also shows an event log, limited to Ajax Type4 devices connected to the central unit. The Event center tab provides detailed information about fire alarms, device faults, disablements, tests, and other important events. The information is organized into separate tabs for easier navigation.
Fire alarm tab
The Fire alarm tab becomes active only when a fire is detected in the system. Tapping this tab opens a list of zones currently in the fire alarm state, sorted by the time the fire started. Selecting a zone from the list displays the alarms registered in that zone.
Fault, test, or disablement tab
The Fault, test, or disablement tab displays all active system events matching the types listed in its name. The tab becomes active only when the system is running a test of Ajax Type4 devices, when some devices are fully or partially disabled, or when a fault has occurred within the fire alarm system, and it has not yet been restored. Tapping this tab opens a list of the corresponding system events.
Event log tab
The Event log tab is always active. Tapping it opens a chronological list of all events and alarms related to the fire alarm system. The central unit event log stores up to 5,000 events.
Fire zones
Type4 Fire Hub Jeweller allows for managing Ajax Type4 devices in different Fire zones. Users can quickly access the Fire zones list from the central unit display to view the current state of each zone and check for any device disablements within them. An admin or a user with access level 2 can initiate a test or disable devices directly from the central unit touch screen.
Authorization
Unauthorized users have access to the central unit Control tab and can perform basic actions: start an indication test, start and stop evacuation.
Authorized users with access level 2 or higher have access to the broader central unit functionality, such as starting evacuation, silencing alarms, running device tests, etc.
Available authorization methods:
- Entering an access code on the central unit display.
Access level 2 can be configured in Ajax apps:
- For admins — in the Users section of the space settings.
An admin with system configuration rights is assigned access level 2 by default. Only a PRO with system configuration rights can manage admin permissions in Ajax PRO apps.
To disable the Fire system access level 2 toggle, the System settings toggle must be disabled first.
- For unauthorized users — in the Access codes section of the central unit settings.
Settings
In the Settings tab on the Type4 Fire Hub Jeweller display, users can adjust the screen backlight brightness and select the interface language. These options are available to all users.
All other central unit settings can be configured via Ajax apps.
Sabotage protection
Type4 Fire Hub Jeweller supports four communication channels for connecting to the Ajax Cloud server: Wi-Fi, Ethernet, and two SIM cards. 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.
The central unit regularly checks the connection quality with all linked devices. If any device loses connection, and the configured timeout expires, all system users (depending on the settings) and the monitoring station will receive a notification of the incident.
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.
A 5 Ah or 10 Ah backup battery can be installed in the central unit. Type4 Internal Battery (24h) provides up to 24 hours of autonomous system operation, while Type4 Internal Battery (72h) offers up to 72 hours.
Internal battery is not included in the central unit complete set and must be bought separately.
OS Malevich
Type4 Fire Hub 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 Fire Hub 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.
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.
Adding the central unit in an Ajax app
We highly recommend creating personal access codes, as well as access codes with access level 2, after adding Type4 Fire Hub Jeweller to a space. A code is required to log in and manage the fire alarm system from the central unit touch screen.
Use the latest versions of Ajax apps to access all available features and ensure proper system operation.
After adding a central unit to your account, you become the admin of the device. Admins can invite other users to the system and determine their rights. You can connect up to 200 users to Type4 Fire Hub Jeweller. Each PRO account connected to the central unit, as well as the security company profile, is considered a user of the system.
If there are already users on the central unit, the central unit admin, PRO with the rights to configure the system, or the installation company maintaining the selected central unit can add your account. You will be notified that the central unit has already been added to another account. Contact our Technical Support to determine who has admin rights on the central unit.

Jeweller
Setting the polling period between the central unit and connected devices. The settings indicate how often the central unit communicates with devices and how fast a connection loss is detected.
- Device ping interval, sec — the frequency of polling of 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 — counter of undelivered packets. The default value is 8 packets.
Do not decrease the default values of the ping interval and ping period unless it is necessary.
The time before sending a message regarding the loss of connection between the central unit and the device are calculated using the following formula:
Detector ping interval × Number of missed pings to determine connection failure
The shorter the ping period, the faster the central unit will know about the events of the connected devices, and the devices will receive central unit commands. Information about alarms and sabotage is transmitted instantly, regardless of the ping interval. Decreasing the ping period will affect the battery life of wireless devices.
The ping interval limits the maximum number of connected devices:
| Interval | Connection limit |
| 12 s | 39 devices |
| 24 s | 79 devices |
| 36 s (by default) | 119 devices |
| 48 s | 159 devices |
| 72 s | 200 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 VADs.
- Standard response — time from alarm detection to device activation is up to 6 s for sounders and up to 13 s for VADs.
Radio interference detection — the following settings ensure the system complies with the EN 50131 (Grade 3) requirements. There are two options:
- Advanced radio interference detection.
- Send radio interference detection event as alarm — if enabled, the notification of a high radio interference level will be sent as an alarm to all system users.
Telephony settings
Telephony settings allow configuring the central unit to communicate with the monitoring station via the SIP protocol.
In Ajax PRO Desktop, you can create and apply a telephony setting template to save time when configuring multiple systems.
Service
Group of central unit service settings. These are divided into two groups: general settings and advanced settings.

This menu allows to manually check whether the new firmware version is available. If so, a PRO or a company with firmware update rights can initiate the update.
Hub system logging
This setting allows you to select the transmission channel for the central unit logs or disable their recording:
- Ethernet — system logs are transmitted over the wired Internet.
- Wi-Fi — system logs are transmitted over the Wi-Fi.
- Off — logging is disabled.
- Cellular for 10 minutes — system logs are transmitted via the cellular channel. 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 errors in the operation of the system.
Delaying notifications of external power loss
Settings for the delay time when sending an external power loss notification.
You can select a delay time from 1 minute to 1 hour with a selection interval of 1 minute.
“While hub offline’ events amount
Events during communication failure with the server are recorded in the central unit buffer and will be delivered to Ajax apps after the connection is restored.
This setting allows you to choose the number of the last events, that central unit will send to Ajax apps after returning online.
You can select between 100 (default value) and 1000 events with increment of 50 events.
Also, all events, related to Type4 devices, are available in the central unit Event log that saves up to 5,000 events. To see the log on the central unit touch screen, go to the Event center tab → Event log tab.
Advanced settings
Server connection
Communication settings between the central unit and the Ajax Cloud server:
- Delay of server connection failure alarm, sec. The delay is necessary to reduce the risk of false notification of a lost connection with the Ajax Cloud server. Activated after 3 unsuccessful central unit–server polls. The delay is set in the range of 30 to 600 s. The recommended default value is 300 s.
- Hub-server polling interval, sec. Frequency of sending pings from the central unit to Ajax Cloud server. It is set in the range of 10 to 300 s. The recommended default value is 60 s.
The time before sending a notification regarding the loss of communication between the central unit and the Ajax Cloud server is calculated using the following formula:
(Ping interval × 3) + Time filter.
With the default settings, Ajax Cloud registers the central unit loss in 8 minutes:
(60 s * 3) + 300 s = 8 min.
- Get notified of server connection loss without alarm. Ajax’s apps can notify about the central unit-server connection loss in two ways: with a standard push notification signal or with an intrusion siren sound (enabled by default). When the option is active, the notification comes with a standard push notification signal.
- Notify of connection loss over channels. The Ajax security system can notify both the users and the security company about the loss of connection 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 via which the system will notify about the loss of connection (Ethernet, Wi-Fi, cellular), as well as the transmission delay of such notifications.
- Loss notification delay, min — time of the delay before sending the notification about the loss of connection via one of the communication channels. Set in the range from 3 to 30 minutes.
The time of sending a notification about the loss of connection via one of the communication channels is calculated using the following formula:
(Ping interval × 3) + Time filter + Notification delay.

Type4 Fire Hub Jeweller supports 64 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.
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.
Selecting the installation site
The central unit is designed for indoor installation only. It is recommended to install it in a visible and easily accessible location — for example, near the entrance on the first floor of the building. This helps ensure timely response to a fire alarm, quick identification of the fire location, and informed decisions about evacuation.
Install the central unit on a vertical surface. This will ensure proper tamper button response if someone attempts to remove the device. Refer to the battery documentation before installation. Note that incorrect positioning may accelerate battery degradation.
Choose a location where the central unit can access all available communication channels: Wi-Fi, Ethernet, and two SIM cards. 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 wireless 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 wireless 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 and Wings signal strength tests 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 Fire ReX Jeweller.
We recommend laying out power or signal cables inside the wall. Otherwise, use the GlandBox wiring accessory with 20 mm cable glands (not included) for external cable routing.
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 wireless Ajax devices.
- In places with high levels of radio interference. This could result in the loss of connection between the central unit and wireless 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 wireless 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 and wired devices.
Before installing Type4 Fire Hub Jeweller make sure that you have selected the optimal location and that it meets the requirements of this manual.
To install Type4 Fire Hub Jeweller:
- Remove the SmartBracket mounting panel from the device. To do this, insert the special tool into the hole, and slide the mounting plate down.
- Carefully break out the necessary perforated part to output the cable from the rear side (top, bottom, or through the wall).
If you are not routing cables inside the wall, use the GlandBox wiring accessory with red cable glands (not included).
- Run the power, Ethernet, and optionally signal cables into the central unit enclosure.
- Secure the SmartBracket mounting panel to a vertical surface at the selected installation site using the bundled screws at all fixation points. One of them is in the perforated part above the tamper button — it is required for tamper alarm triggering in case of any attempt to detach the device.
The UP key on SmartBracket marks the top of the device. Orient these markings when installing the central unit. Also use the bubble level to check the inclination angle of the mount during installation.
- Connect the Ethernet, external power cable, and optionally signal cables to the appropriate connector and terminals.
Selecting the cables for connecting to power supply and relay outputs, adhere to the rules and requirements of regulatory legal acts on electrical safety.
1 — Ethernet cable connector.
2 — terminals for connecting external power supply 110–240 V, 50/60 Hz.
3 — relay output for connecting the signal cable for sending events to the monitoring station in case of any fault in the system.
4 — relay output for connecting the signal cable for sending events to the monitoring station in case of fire alarm. - Install the internal battery.
Use only Type4 Internal Battery (24h) or Type4 Internal Battery (72h). We do not guarantee correct device operation with third-party batteries, and they can cause the central unit to fail.
- Install SIM cards:
1 — the first micro SIM slot.
2 — the second micro SIM slot. - Add the central unit to a space.
- Place the turned on device on the SmartBracket mounting panel.
- Switch on the external power supply, if the power cable was de-energized previously.
- Check the status of the central unit in an Ajax app. If a tamper alarm is indicated, ensure that the mounting panel is closed tightly.
- Run the central unit indication test.
If Ethernet connection fails
If the Ethernet connection is not established, disable proxy and MAC address filtration 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 the Ajax app.
If SIM connection fails
To connect to the cellular network, you need to install a micro SIM card with a PIN code request disabled and a sufficient amount of funds on the account to pay for services as per the operator’s tariff. To disable the PIN code request, insert the SIM card into the phone.
If the central unit fails to connect to the cellular network, use Ethernet to configure the network parameters: roaming, APN access point, user name, and password. To find out these parameters, contact the support service of your mobile operator.

How to run Zone test
Zone test is a special mode that allows installers to check fire detector operation in selected zones. In test mode, smoke detectors respond to test aerosols, such as Solo 332. During the test, installers can define which outputs, such as sounders, visual alarm devices (VADs), or I/O module relays, will be activated in each zone.
An admin or user with access level 2 can run Zone test from the central unit touch screen or via Ajax apps.
- Go to the Fire zones tab on the central unit touch screen.
- Select the required zone.
- Tap Run zone test.
- Select whether to activate outputs (sounders, VADs, and relays) during the test:
- Don’t activate outputs
- Activate only in tested zones
- Activate in all zones.
- If the Activate only in tested zones or Activate in all zones option is selected, choose the devices to be triggered by the test alarm:
- Sounders
- VADs
- Relays.
- Tap Start test.
To add another zone to the current test, select the required zone and tap Add to current zone test.
