Operating principle

LineSupply Fibra is a module for additional power supply of devices on the Fibra line. You can connect LineSupply at any point along the line, even after another LineSupply.

LineSupply (45 W) features one output line, while LineSupply (75 W) offers two output lines for connecting wired devices. The maximum number of devices that can be connected to the module is determined by the hub (100 devices for Hub Hybrid with standard settings) and the LineSupply output power.

The output power of the module is distributed between the connected devices and the backup battery. For LineSupply (45 W), the distribution is 30 W for devices and 15 W for the backup battery; for LineSupply (75 W) it is 30 W for each output line and 15 W for battery charging.

The module has protection against short circuits and overvoltage on the Fibra output lines. In case of a short circuit or overvoltage, LineSupply turns off the affected output line and attempts to restore power after 12 seconds. If the issue persists, the module de-energizes the line again, repeating this process until normal operation is restored.

LineSupply identifies the malfunction type, and the system sends the corresponding notification to the Ajax apps.

Fibra data transfer protocol

The module uses Fibra technology to transmit alarms and events. It is a wired data transfer protocol for fast and reliable two-way communication between the hub and connected devices.

Sending events to the monitoring station

The Ajax system can transmit alarms to both PRO Desktop monitoring app and the central monitoring station (CMS) in the formats of SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.

LineSupply can transmit the following events:

  1. Tamper alarm and recovery; the module features a connector for attaching a tamper board, included in the Case complete set.
  2. Tamper board connection/disconnection.
  3. Low voltage detection on the module output line and voltage restoration to normal values.
  4. Short circuit detection on the Fibra line and power supply restoration.
  5. Overvoltage detection on the module output signal lines and voltage restoration to normal values.
  6. Backup battery connection/disconnection to the module.
  7. Low backup battery charge and battery charge restoration.
  8. Backup battery malfunction/restoration.
  9. Main power supply loss/restoration.
  10. Connection loss/restoration between LineSupply and the hub.
  11. Module output line power is turned off/on.
  12. Malfunction detection; the module cannot charge the backup battery.
  13. Permanent device deactivation/activation.
  14. One-time device deactivation/activation.
  15. Device temperature is out of acceptable limits; temperature restoration to normal values.

Information including the involved line number is transmitted for all events on the LineSupply (75 W) output lines.

When an alarm is received, the operator at the security company’s monitoring station knows what happened and precisely where to dispatch a rapid response team. The addressability of Ajax devices allows sending events to PRO Desktop or the CMS, including the device type, its name, security group, and virtual room. Please note that the list of transmitted parameters might vary depending on the CMS type and the selected communication protocol for the monitoring station.

The device’s ID and number can be found in its states in the Ajax app.

Adding to the system

LineSupply Fibra is compatible only with Hub Hybrid (2G) and Hub Hybrid (4G). Only verified partners can add and configure Fibra devices in Ajax PRO apps.

Types of accounts and their rights

Before adding a device

  1. Install Ajax PRO app and sign in to the PRO account.
  2. Add a hub that is compatible with LineSupply to the app. Configure the necessary settings and create at least one virtual room.
  3. Ensure that the hub is switched on and has an internet connection, through Ethernet and/or a mobile network.
  4. Ensure that the hub is disarmed and does not start updating by checking its status in the Ajax app.
  5. Ensure that LineSupply is physically connected to the hub and is powered.

Connecting to the hub

There are two ways to add devices in the Ajax PRO app: automatically and manually.

To add a device automatically:

  1. Open the Ajax PRO app and select the hub to which you want to add LineSupply.
  2. Go to the Devices tab and click Add Device.
  3. Select Add all Fibra devices. The hub will scan the Fibra lines. After scanning, all devices connected to the hub that have not been added to the system will be displayed.
  4. Select the desired device from the list. Upon selection, the LED indicator will flash to identify this device.
  5. Name the device, and select the room and security group if Group Mode is enabled. Click Save.

If the connection attempt fails, verify that the wired connection is correctly set up before trying again. If the maximum number of devices (100 for Hub Hybrid) has already been added to the hub, you will receive an error notification while adding.

Once connected to the hub, the module will appear in the list of hub devices in the Ajax app. The device status update frequency in the list depends on the Jeweller/Fibra settings, with the default value of 36 seconds.

LineSupply works with only one hub. When connected to a new hub, the device stops sending events to the old one.

Adding the module to a new hub does not automatically remove it from the device list of the old hub. This must be done through the Ajax app.

Malfunctions

When a LineSupply malfunction is detected, the Ajax app displays a malfunction counter on the device icon. All malfunctions are indicated in the module states. Fields with malfunctions will be highlighted in red.

A malfunction is displayed if:

  • the casing is detached from the surface or its integrity is compromised;
  • short circuit on the Fibra line;
  • overvoltage on the module output signal lines;
  • low voltage on the module output line;

Functionality testing

The Ajax system offers several types of tests to help select the correct installation place for the devices. Tests do not start immediately. However, the waiting time does not exceed the duration of one “hub—device” polling interval. The polling interval can be checked and configured at hub settings (HubSettings Jeweller/Fibra).

To run a test, in the Ajax app:

  1. Select the required hub.
  2. Go to the Devices tab.
  3. Select LineSupply from the list.
  4. Go to the Settings .
  5. Run the Fibra Signal Strength Test.

Device placement

Install LineSupply on the line before the Fibra devices with the highest power consumption, which may lack power from the hub. These could be devices like sirens or keypads, for example. LineSupply can also function as a repeater to extend the line’s range.

While you can install the module even after another LineSupply, avoid connecting the module’s Fibra output lines in a Ring topology.

When choosing a location for LineSupply, consider the parameters that affect its operation:

  • Fibra signal strength.
  • Length of the cable used to connect LineSupply.
  • Length of the cable connecting wired devices to LineSupply.

Follow these recommendations when designing the system project for an object. Only professionals should design and install the Ajax system. The list of authorized Ajax partners is available here.

Installing into Case

To install LineSupply, use Case C (260) or Case D (430), which are sold separately. You can mount one LineSupply in Case C (260) and several modules or other devices in Case D (430).

Each Case is equipped with mounts for the modules, wire channels, and a tamper that can be connected to LineSupply.

LineSupply in Case C (260) LineSupply in Case D (430)

Do not install LineSupply

  1. Outdoors, as it can lead to module failure.
  2. Inside premises where temperature and humidity levels exceed the permissible limits, as this can damage the module.
  3. In places with low or unstable Fibra signal strength, since this might cause a loss of connection with the hub.

Fibra Signal Strength

The Fibra signal strength is determined by the number of undelivered or corrupted data packages over a certain period of time. The icon in the Devices tab indicates the signal strength:

  • three bars — excellent signal strength;
  • two bars — good signal strength;
  • one bar — low signal strength, stable operation is not guaranteed;
  • crossed out icon — no signal.

Lines Power Test

The test simulates the maximum energy consumption of devices connected to the hub. If the system passes the test successfully, all its devices have enough power in any situation.

After the test, the app displays a notification with the status of each line:

  • test passed;
  • test passed with malfunctions;
  • test failed.

If Lines Power Test fails or passes with a malfunction, the device list will indicate which devices are connected to the hub via LineSupply.

For devices connected to LineSupply (75 W), the list additionally indicates the number of the output line on which devices are located.

Designing

It is crucial to design the system project properly to ensure the correct installation and configuration of the devices. The design must consider the number and types of devices at the object, their exact locations and installation heights, the length of wired Fibra lines, the type of cable used, and other parameters. Refer to the article to learn tips for designing the Fibra system project.

LineSupply can connect at any point on the Fibra line. When using a U/UTP cat.5 twisted pair cable, the output line length (between LineSupply and the last device) can be up to 2,000 meters. Any Fibra device can be connected to the module’s output line, such as opening detectors, motion detectors, sirens, and keypads. However, the number of wired devices in the system is limited by the module’s output power per line (up to 30 W) and the hub’s technical specification. You can connect up to 100 devices to Hub Hybrid.

While Ajax systems support Beam and Ring topologies, avoid connecting the module’s Fibra output lines in a Ring topology.

Cable length and type

Recommended cable types:

  • U/UTP cat.5 4 × 2 × 0.51, copper conductor.
  • Signal cable 4 × 0.22, copper conductor.

The maximum line length of up to 2,000 m is relevant when using U/UTP cat.5, 4 × 2 × 0.51 cable. Please note, the wired connection range might vary if other cable types are used. As of now, no other cable types have been tested.

Verification using a calculator

To ensure that the project is designed correctly and the system functions as intended in practice, we have developed a Fibra power supply calculator. It helps to check the communication quality and cable length for wired Fibra devices when designing the system project.

Preparing for installation

Cable arrangement

Before laying cables, check the electrical and fire safety regulations applicable in your region. Strictly follow these standards and regulations. Tips for cable arrangement are available in this article.

Cable routing

Before beginning the installation, we strongly advise reviewing the Device placement section thoroughly. Stick to the outlined system project without deviation. Violation of the basic LineSupply installation rules and the recommendations of this manual may lead to incorrect operation, as well as loss of connection with the device. Tips for cable routing are available in this article.

Preparing cables for connection

First, remove the insulation layer and strip the cable with a special insulation stripper. The ends of the wires inserted into the device terminals must be tinned or crimped with a sleeve. It ensures a reliable connection and protects the conductor from oxidation. Tips for preparing the cables are available in this article.
