Operating principle

Button is a wireless panic button that, when pressed, transmits an alarm to users, as well as to the security company’s CMS. In Control mode, Button allows you to control Ajax automation devices with a short or long press of a button.

In panic mode, the Button can operate as a panic button and signal about a threat, or notify of the need for auxiliary help, or inform about the intrusion, fire, gas alarm, or leakage. You can select the type of alarm in the button settings. The text of alarm notifications depends on the selected type, as well as the event codes transmitted to the central monitoring station of the security company (CMS).

In the Button settingsScenarios menu, you can assign the action of an automation device (Relay, WallSwitch or Socket) to a button press.

The Button is equipped with protection against accidental press and transmits alarms at a distance of up to 1,300 m from the hub. Please be aware that the presence of any obstructions that impede the signal (for example, walls or floors) will reduce this distance.

Button is easy to carry around. You can always keep it on a wrist or a necklace. The device is resistant to dust and splashes.

When connecting Button via radio signal range extender, please note that Button does not automatically switch between the radio networks of the radio signal extender and the hub. You can manually assign Button to another hub or range extender in the app.

Connecting the button to the Ajax system

Prior to initiating connection

  1. Follow the hub instructions to install the Ajax application. Create an account, add a hub to the app, and create at least one room.
  2. Enter the Ajax app.
  3. Activate the hub and check your internet connection.
  4. Ensure that the hub is not in armed mode and is not being updated by checking its status in the app.

Only users with administrative rights can add a device to the hub.

In order to connect a Button

  1. Click on Add Device in the Ajax app.
  2. Name the device, scan its QR code (located on the package) or enter it manually, select a room and a group (if group mode is enabled).
  3. Click Add and the countdown will begin.
  4. Hold the button for 7 seconds. When the Button is added, the LEDs will flash green once.

For detection and pairing, the Button must be located within the hub radio communication zone (on the single protected object).

The connected button will appear in the list of hub devices in the application. Updating the statuses of the device in the list does not depend on the polling time value in the hub settings. Data is updated only by pressing the Button.

The Button only works with one hub. When connected to a new hub, the button Button stops transmitting commands to the old hub. Note that after being added to the new hub, the Button is not automatically removed from the device list of the old hub. This must be done manually through the Ajax application.

Use cases

Panic Mode

In the panic button mode, Button can call security or help, as well as alert of an emergency by activating sirens and sending other users a notification in the app. In the Button settings, you can select one type of alarm out of eight:

  • Intrusion
  • Fire
  • Auxiliary alarm
  • Panic button
  • Gas alarm
  • Malfunction
  • Leakage
  • Custom (not sent to the security company monitoring station)

The type of alarm determines the event code sent to the security company monitoring station (CMS) and the notification text received by the user. This ensures the accurate response to the threat.

Note that in Panic Mode, pressing the Button will raise an alarm regardless of the system security mode.

If Button is pressed, an alarm can also run a scenario in the Ajax system.

Button can be installed on a flat surface or carried around. To install on a flat surface (for example, under the table), secure the Button with double-sided adhesive tape. To carry the Button on the strap: attach the strap to the Button using the mounting hole in the main body of the Button.

Control Mode

Button can be used to control the automation devices. In Control mode, the Button has two pressing options: short and long (the button is pressed for more than 3 seconds). These pressings can trigger the execution of an action by one or more automation devices: Relay, WallSwitch, or Socket.

To bind an automation device action to a long or short press of a Button:

  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 the gear icon .
  3. Select the Control mode in the Operation mode section. Click on the actual Button device to save the changes
  4. Go to the Scenarios menu. Click Create Scenario if you are creating a scenario for the first time, or Add Scenario if scenarios have already been created in the security system.
  5. Select a pressing option to run the scenario: Short press or Long press.
  6. Select the automation device to execute the action.
  7. Enter the Scenario Name and specify the Device Action to be executed by pressing the Button.
    • Switch on
    • Switch off
    • Switch the state

    The Device Action setting is unavailable when configuring a scenario for the automation devices operating in pulse mode. During the scenario execution, such devices will close/open the contacts for a set time. The operating mode and pulse duration are set in the automation device settings.

  8. Click Next. The scenario will appear in the list of device scenarios.

Mute Interconnected Fire Detectors Alarm

By pressing the Button, the interconnected fire detectors alarm can be muted (if the corresponding operating mode of the button is selected). The reaction of the system to pressing a button depends on the state of the system:

  • The Interconnected Fire Detectors Alarm have already propagated — by the first press of the Button, all fire detectors sirens are muted, except for those that registered the alarm. Pressing the button again mutes the remaining detectors.
  • The interconnected alarms delay time lasts — the siren of the triggered Ajax fire detector is muted by pressing.

With the OS Malevich 2.12 update, users can mute fire alarms in their groups without affecting detectors in the groups to which they do not have access.

Button can be fixed on a surface or carried around.

How to fix Button

To fix Button on a surface (e. g. under a table), use Holder.

ajax button

To install the button in the holder:

  1. Choose a location to install the holder.
  2. Press the button to test whether the commands can reach the hub. If not, choose another location or use a radio signal range extender.

    When connecting Button via radio signal range extender, note that Button does not automatically switch between the radio networks of the radio signal extender and the hub. You can assign Button to another hub or range extender manually in the app.

  3. Fix Holder on the surface using the bundled screws or double-sided adhesive tape.
  4. Put Button into the holder.

Please note that Holder is sold separately.

How to carry around Button

ajax button

The button is convenient to carry with you thanks to a special hole on its body. It can be worn on the wrist or around the neck, or hung on a key ring.

Button has an IP55 protection rating. This means that the device body is protected from dust and splashes. Tight buttons are recessed into the body and software protection helps to avoid accidental pressing.


Clean the button body from dust, cobwebs and other contaminants as they appear. Use a soft, dry cloth for cleaning appliances. Never use substances containing alcohol, acetone, gasoline and other active solvents to clean the Button.

The pre-installed battery provides up to 5 years of Button operation in normal use (one press per day). More frequent use may reduce battery life. You can check battery level in the Button states in the Ajax app.

The pre-installed battery is sensitive to low temperatures and if the key fob is cooled significantly, the battery level indicator in the app may show incorrect values until the key fob becomes warmer.

The battery level value is updated each time the button is pressed.

When the battery has run down, the user will receive a notification in the Ajax app, and the LED indicator will smoothly light up red and go out each time the button is pressed.
