FAQ

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

Add a key fob to the receiver and assign buttons to the corresponding zones. The zones must be added to the 24-hour zones of the control panel.

Only one key fob button can be assigned to a single ocBridge Plus zone. When you select the type of zone “Arming/Disarming”, two buttons of the key fob are assigned to the zone at once (arming and disarming).

Copied

Yes, if the third-party system supports the UART data interface and the communication protocol can be configured or programmed. To configure uartBridge, use the uartBridge protocol.

If you have troubles with setting up a third-party security system with uartBridge, please, contact the manufacturer of this device.

Copied

uartBridge does not have dry contacts (NC/NO outputs), but there is a two-way data transfer protocol via the UART interface. With it, you can get information about each device (battery, alarm, sensor status) and connect up to 85 devices.

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, ocBridge Plus response period is set to ping detectors every 36 seconds and to signal an alert after 40 undelivered passes. Under these settings, it will take about 24 minutes for the system to recognize a communication failure.

You can adjust these settings by opening the Ajax configuration settings and connecting to ocBridge Plus. Find the Service Events Control tab, then Lost Connection, and change Passes Number. You can change response period in the Radio Zone tab.

The maximum distance between the Hub and the detector can reach up to 2000 meters in open spaces. Walls, ceilings and other structures between Hub and the detector, reduce the range of action several times. In this case, the maximum distance depends on the material, thickness, and configuration of the walls.

Copied

The detector is set to Always Active. If you don’t need this level of security, you can turn it off in the detector settings.

Always active mode is required for round-the-clock protection of an object, regardless of security system status (armed or disarmed)

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.

At the moment, such an opportunity is not provided, since the equipment of other manufacturers uses other frequencies and communication protocols with the control panels.

You can connect any IP camera using RTSP to the Ajax security system. In total, you can connect up to 10 cameras to Hub, up to 25 cameras to Hub 2, up to 50 cameras to Hub Plus, and up to 100 cameras to Hub 2 Plus.

Dahua cameras and video recorders can be added by scanning their QR codes (similarly to Ajax devices). And EZVIZ, Hikvision and Safire video surveillance systems can be added to the hub with a few clicks. So you don’t have to waste time on setting up network equipment.

Video recorders allow you to bypass the limit on the number of video surveillance devices that can be connected to the hub. The video recorder is a single device to which you can connect multiple video cameras. The video stream from each camera will be available in the Ajax app.

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. Hub Settings 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.
