DoubleButton is a wireless hold-up device with advanced protection against accidental presses. The device communicates with a hub via the encrypted Jeweller radio protocol and compatible only with Ajax system. The line-of-sight communication range is up to 1300 meters. DoubleButton operates from the pre-installed battery up to 5 years.
DoubleButton is connected and configured via Ajax apps on iOS, Android, macOS, and Windows. Push notifications, SMS, and calls can notify about alarms and events.
Functional elements

- LED indicators / plastic protective divider
- Mounting hole
Operating principle
DoubleButton is a wireless hold-up device, featuring two tight buttons and a plastic divider to protect against accidental presses. When pressed, it raises an alarm (hold-up event), transmitted to users and to the security company’s monitoring station.
An alarm can be raised by pressing both buttons: one-time short or long press (more than 2 seconds). If only one of the buttons is pressed, the alarm signal is not transmitted.
All DoubleButton alarms are recorded in the Ajax app’s notification feed. The short and long presses have different icons, but the event code sent to the monitoring station, SMS, and push notifications do not depend on the pressing manner.
DoubleButton can only operate as a hold-up device. Setting the type of alarm is not supported. Keep in mind that the device is active 24/7, so pressing the DoubleButton will raise an alarm regardless of the security mode.
Only alarm scenarios are available for DoubleButton. The control mode for automation devices is not supported.
Event transmission to the monitoring station
The Ajax system can connect to the CMS and transmit alarms to the monitoring station in SurGard (Contact ID), ADEMCO 685, SIA (DC-09) and other proprietary protocols. A complete list of supported protocols is available at the link.
Connection
The device is not compatible with ocBridge Plus, uartBridge, and third party security control panels.
Before starting connection
- Install the Ajax app. Create an account. Add a hub to the app and create at least one room.
- Check if your hub is on and connected to the Internet (via Ethernet cable, Wi-Fi, and/or mobile network). You can do this in the Ajax app or by looking at the Ajax logo on the front panel of the hub. The logo should light with white or green if the hub is connected to the network.
- Check if the hub is not armed and does not update by reviewing its status in the app.
Only users with administrator permissions can connect a device to a hub.
How to connect DoubleButton to a hub
- Open the Ajax app. If your account has access to several hubs, select the hub to which you want to connect the device.
- Go to the Devices tab
and click Add device. - Name the device, scan or enter the QR code (located on the package), select a room and a group (if group mode is enabled).
- Click Add — the countdown will begin.
- Hold any of two buttons for 7 seconds. After adding DoubleButton, its LED will flash green once. DoubleButton will appear in the list of hub devices in the app.
and click Add device.
To connect DoubleButton to a hub, it should be located on the same protected object as the system (within the hub’s radio network range). If the connection fails, try again in 5 seconds.
DoubleButton can be connected to one hub only. When connected to a new hub, the device stops sending commands to the old hub. Added to a new hub, DoubleButton is not removed from the device list of the old hub. This must be done manually in the Ajax app.
Updating the device statuses in the list occurs only when DoubleButton is pressed and does not depend on the Jeweller settings.

Alarms
A DoubleButton alarm generates an event notification sent to the security company’s monitoring station and system users. The pressing maner is indicated in the event feed of the app: for a short press, a single-arrow icon appears, and for a long press, the icon has two arrows.
To reduce the probability of false alarms, a security company can enable the alarm confirmation feature.
Note that the alarm confirmation is a separate event that does not cancel the alarm transmission. Whether or not the feature is enabled, DoubleButton alarms are sent to a CMS and to security system users.

Application
DoubleButton can be fixed on a surface or carried around.
How to fix DoubleButton on a surface
To fix the device on a surface (e. g. under a table), use Holder.
To install the device in the holder:
- Choose a location to install the holder.
- Press the button to test whether the commands are delivered to a hub. If not, choose another location or use a radio signal range extender.
When routing DoubleButton through a radio signal range extender, keep in mind that it does not automatically switch between a range extender and a hub. You can assign DoubleButton to a hub or another range extender in the Ajax app.
- Fix Holder on the surface using the bundled screws or double-sided adhesive tape.
- Put DoubleButton into the holder.
Please note that Holder is sold separately.
How to carry DoubleButton
The button is easy to carry around thanks to a special hole on its body. It can be worn on the wrist or neck, or be hanged on a keyring.
DoubleButton has an IP55 protection index. Which means that the device body is protected from dust and splashes. And a special protective divider, tight buttons, and the need to press two buttons at once eliminate false alarms.
Using DoubleButton with alarm confirmation enabled
Alarm confirmation is a separate event that a hub generates and transmits to a CMS if the hold-up device has been activated by different types of pressing (short and long) or two specified DoubleButtons have transmitted alarms within a specified time. By responding to confirmed alarms only, a security company and police reduce the risk of unnecessary reacting.
Note that the alarm confirmation feature does not disable the alarm transmission. Whether or not the feature is enabled, DoubleButton alarms are sent to a CMS and to security system users.
How to confirm alarm with one DoubleButton
To raise a confirmed alarm (hold-up event) with the same device, you need to perform any of these to actions:
- Hold both buttons simultaneously for 2 seconds, release, and then press both buttons again briefly.
- Simultaneously press both buttons briefly, release, and then hold both buttons for 2 seconds.
How to confirm alarm with several DoubleButtons
To raise a confirmed alarm (hold-up event), you can activate one hold-up device twice (according to the algorithm described above) or activate at least two different DoubleButtons. In this case, it doesn’t matter in what way two different DoubleButtons were activated — with a short or long pressing.
Maintenance
When cleaning the device body, use products suitable for technical maintenance. Do not use substances containing alcohol, acetone, gasoline, or other active solvents to clean DoubleButton.
The pre-installed battery provides up to 5 years of operation, considering one pressing per day. More frequent use may decrease battery life. You can check the battery status at any time in the Ajax app.
Keep new and used batteries away from children. Do not ingest battery, Chemical Burn Hazard.
If DoubleButton cools down up to -10°C and below, the battery charge indicator in the app can show low battery status until the button heats up to above-zero temperatures. Note that the battery charge level is not updated in the background, but only by pressing DoubleButton.
When the battery charge is low, users and a security company monitoring station receive notification. The device LED smoothly lights up red and goes out after each button pressing.
