Two types of scenarios can be bound to SpaceControl, KeyPad Plus or KeyPad:

  1. by alarm;
  2. reaction to arming/disarming.

If you choose scenario by alarm, an automation device (Relay, WallSwitch or Socket) will be triggered by pressing SpaceControl or KeyPad panic button.

Also, the automation device can respond to arming/disarming using SpaceControl or KeyPad. However, in this case, the device will also respond to automatic arming/disarming according to the schedule or using the app. In this type of scenario, the determining factor will be the system status, not the control device.

Button operates in two modes: as a panic button and as a control button. In the panic button mode, pressing the Button raises an alarm, which, in turn, can trigger a scenario. In the control button mode, the Button controls automation devices by long or short pressing, without raising an alarm.

To change the Button operation mode:

  1. Open the Ajax app and go to the Devices tab.
  2. Select Button in the list of devices and go to settings by clicking on the gear icon .
  3. Select the needed mode (Panic or Control) in the Operating mode section.

Without obstacles, the communication range between the hub and the device is up to 1,300 meters.

If key fob commands are not delivered to the security system, relocate the hub to minimize obstacles between the hub and the key fob.

If the key fob range is insufficient after relocation, use a security system radio signal range extenders


The QR code is on the lid of the key fob box. If you don’t have the box at hand, disassemble the key fob, separating the halves of the body via a thin flat object. You will find another QR code inside.


When using SpaceControl with Ajax hub, you can disable only the panic button. To disable the panic button:

To disable the alarm button:

  1. Go to the SpaceControls settings.
  2. Disable the panic button with toggle.

Reassignment of the SpaceControl buttons is not provided. It is possible to adjust buttons’ settings to control the third-party central unit when SpaceControl is connected to it via ocBridge Plus.


You can’t assign the key fob to the several hubs. It can only work with one device it was assigned last.


Yes, you can. The keyfob is compatible with wired and wireless systems using Ajax ocBridge Plus or Ajax uartBridge.


The duress code allows for simulating an alarm shutdown. In this case, you won’t be given away by the Ajax application and sirens installed at the facility, and the security company and other security system users will be warned about the incident.

Alarm special features when entering the duress code:

  • The security company’s Central Monitoring Station (CMS) will receive a “disarming under duress” alarm event. The response unit responds accordingly after arriving at the facility.
  • All users of your hub receive notifications of security system disarming, where the disarming icon (torn circle on the user icon) will be red.

If the security system is disarmed using the duress code by mistake, contact the Central Monitoring Station (CMS)

The duress code can be set in the user settings:

  1. HubSettings UsersYour profile settings User passcode

Available in hubs with firmware version OS Malevich 2.6 or later

Each user sets a personal password individually in their profile settings (HubSettings UsersYour profile settings ).

After choosing a personal password, it is necessary to enter the following in order to arm a specific group:

  • User identifier * Personal password * Group identifier → Arming button

The user identifier is available in the profile settings


Available in hubs with firmware version OS Malevich 2.6 or later

In order to assign the keypad to a group:

  1. Go to the keypad settings (KeypadSettings )
  2. Select the required group in the Arming/Disarming permission menu.

After this, the keypad will control arming/disarming only for the selected group.



Tamper is a miniature button on the device board. It is released when the lid is opened as well as a result of an attempt to unfasten and/or lift the device from the surface, which initiates an event.

When the tamper is released, the Hub sends push notifications and SMS messages (if this type of notification is enabled) to all users of the security system and also communicates the event to the central monitoring station of the security company.

If the tamper is released, Ajax applications display the Open status in the Lid field of the device menu. In addition, a malfunction badge appears on the device icon.



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:

Ping interval * (number of undelivered packets + 1 correction packet).

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.


The loop (zone) number is required to add a guarded facility to the CMS along with descriptions of all devices connected to the hub.

The loop (zone) number is available in the settings after activating the group mode in the Ajax application:

  1. HubSettings Groups

Having selected a group, you will see a list of its devices. Each device has a Device No. (or DeviceIndex in Ajax PRO Desktop) that corresponds to the loop (zone) number. A number is assigned when a device is attached to the Hub. The first added device has the first loop (zone) number.

After a device or a detector is removed, its number will be assigned to the next added device. However, the numbering of other devices will not change.


How to find out the device identifier (ID)

The identifier (ID or serial number) of the device can be found out in the Ajax app or on the box of the device.

How to find out the identifier on the box

Each package contains two device IDs: at the bottom of the box and under the lid.

ID at the bottom of the box

ID under the lid

How to find out the ID in an Ajax app

  1. Sign in to the Ajax app.
  2. Select the required hub from the list if you have several of them or if you are using a PRO app.
  3. Go to the Devices menu.
  4. Select a device from the list. Device ID information is located at the bottom of the status screen.

How to find out the device firmware version

The firmware version of the device can be found in the Ajax apps. In order to obtain it:

  1. Sign in to the Ajax app.
  2. Select the required hub from the list if you have several of them or if you are using a PRO app.
  3. Go to the Devices menu.
  4. Select a device from the list. The firmware version information is located on the status screen at the bottom.

Go to the Device tab , select the device you want to check.
