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.

3. Mounting hole

All DoubleButton alarms are recorded in the 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.

How to connect DoubleButton to a hub

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,

1. Install the . Create an . Add a hub to the app and create at
least one room.

2. 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.

3. Check if the hub is not armed and does not update by reviewing its status in
the app.

1. Open the Ajax app. If your account has access to several hubs, select the hub
to which you want to connect the device.

2. Go to the Devices tab and click Add device.

3. Name the device, scan or enter the QR code (located on the package), select a

room and a group (if group mode is enabled).

4. Click Add— the countdown will begin.

5. 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.

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.

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:

1. Choose a location to install the holder.

2. Press the button to test whether the commands are delivered to a hub. If not,

choose another location or use the .

When routing DoubleButton through ReX, 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 ReX in the Ajax app.

ReX radio signal range extender

3. Fix Holder on the surface using the bundled screws or double-sided adhesive
tape.

4. 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:

How to configure confirmation of a hold-up device

1. Hold both buttons simultaneously for 2 seconds, release, and then press both
buttons again briefly.

2. 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.

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.
