LineSplit is a module designed to split Fibra lines in a wired or hybrid Ajax system. LineSplit connects to any point of the Fibra line and splits it into four lines. Each device output line can have a length of up to 2,000 meters when connected using the U/UTP cat.5 twisted pair cable.

Do not connect Fibra output lines created with LineSplit in a Ring topology. Learn more

LineSplit modules can be connected one after another. Up to 10 LineSplit Fibra modules can be installed one after the other, connecting each module to the output line of the previous one. The total output current on the hub lines and the hub specifications limits the number of connected devices. You can connect up to 100 devices to Hub Hybrid.

LineSplit Fibra does not provide additional power supply to the line. To provide additional power supply to the line, LineSupply Fibra can be used.

LineSplit is designed for indoor installation. We recommend installing LineSplit into Case (the casing is sold separately). The casing is available in multiple versions.
The module is equipped with a connector for a tamper board (included in the Case complete set). The tamper reacts if someone tries to break or open the casing lid. If it triggers, the notification is sent to the Ajax apps.
What is the tamper
Fibra data transfer protocol

LineSplit 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.
Learn more
Sending events to the monitoring station
The Ajax system can transmit alarms to the PRO Desktop monitoring app, as well as to the central monitoring station (CMS) using SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other protocols.
LineSplit can transmit the following events:
1. Tamper alarm. Tamper recovery. 2. Low supply voltage and when voltage returns to normal. 3. Loss of communication between LineSplit and the hub. Reconnecting. 4. Temporary deactivation/activation of the device. 5. Short circuit on the Fibra line and when the power supply is restored.
. Overvoltage on the Fibra line and when voltage returns to normal.
When an alarm is received, the CMS operator knows exactly what happened and where to send the rapid response team. The Ajax devices are addressable, meaning that PRO Desktop app and CMS receive events, device type, assigned name, and location (room, group). The list of transmitted parameters may differ depending on the type of CMS and the selected communication protocol.
You can find the device ID, loop (zone) number, and the line number in the device States.
Selecting the installation site for LineSplit
When choosing a spot to install LineSplit, consider the parameters that affect the operation of the device:

Fibra signal strength. The length of the cable used to connect LineSplit. Length of the cable used to connect wired devices to LineSplit. Follow these recommendations when designing the Ajax system project for an object. The security system should be designed and installed by professionals. The list of authorized Ajax partners is available here.
Installing into Case
LineSplit is designed for indoor installation only. It is recommended to install device into Case. The casing is available in multiple versions. Installing one LineSplit module or several devices into Case is possible. Use Case configurator to get the most optimal placement of your Fibra devices in the casing. Case has mounts for the modules, wire channels, and a tamper that connects to LineSplit. The CMS and users receive notifications if someone tries to break the casing or open the lid.
Case is sold separately from LineSplit.
Learn more about Case

LineSplit cannot be installed
1. Outdoors. This could damage the module. 2. Inside premises with temperature and humidity values that do not
correspond to the operating parameters. This could damage the module. 3. In places with low or unstable Fibra signal strength. 4. Without Case.
Fibra signal strength
Fibra signal strength is determined by the ratio of the number of undelivered or corrupted data packages to those expected over a specific time. The icon in the Devices tab in Ajax apps 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; stable operation is not guaranteed.
The following factors affect the signal strength:
The number of devices on the Fibra line. Cable length and type. The correctness of the wire connections to the terminals.
What is Fibra Signal Strength Test
Lines Power Test
The test simulates the maximum energy consumption of devices connected to the control panel: the detectors give alarms, sirens turn on, and keypads activate. If the system passes the test successfully, all its devices have enough power in any situation.

If at least one Fibra line does not have enough power, the app displays a notification with the status of each line:
Test passed.
Test passed with malfunctions.
Test failed.
What is Lines Power Test
Designing the system project
It is crucial to properly design the system project to install and configure the devices correctly. The project must take into account the number and types of devices at the object, their exact location and installation height, the length of wired Fibra lines, the type of cable used, and other parameters. Read the article to learn tips for designing the Fibra system project.
LineSplit can be connected at any point of the Fibra line, splitting it into four lines. Each output line of the device can have a length of up to 2,000 meters when connected using the U/UTP cat.5 twisted pair cable.
Different types of devices can be connected to the same Fibra line. For example, you can use opening detectors, motion detectors supporting photo verification, sirens, keypads, and LineSplit modules on the same line.

Connecting multiple LineSplit modules one after the other allows you to expand the Ajax system by splitting lines. One Fibra line splits into four, four into sixteen, and so on. Up to 10 LineSplit Fibra modules can be installed one after the other, connecting each module to the output line of the previous one. The number of wired devices in the system is limited by the output current of the hub and its specifications. You can connect up to 100 devices to Hub Hybrid.
LineSplit Fibra does not provide additional power supply to the line. To provide additional power supply to the line, LineSupply Fibra can be used.
If LineSplit is the last device on the line, the terminating resistor jumper is installed on two contacts.
Ajax systems also support Beam (Radial) and Ring topologies. The output lines created when using LineSplit do not support the Ring topology.
More about topologies
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 wired connection range may vary if you use a different cable type. No other types of cables have been tested.
Verification using a calculator
To make sure that the project is designed correctly and that the system will work in practice, we have developed a Fibra power supply calculator. The calculator

helps to check the communication quality and cable length for wired Fibra devices when designing the system project.
Preparing for installation
Cable arrangement
When preparing to lay cables, check the electrical and fire safety regulations in your region. Strictly follow these standards and regulations. Tips for cable arrangement are available in this article.
Cable routing
We recommend you to carefully read the Selecting the installation site section before installation. Avoid deviations from the system project. Violating the basic installation rules and the recommendations of this manual may lead to incorrect operation and loss of connection with LineSplit. Tips for cable routing are available in this article.
Preparing cables for connection
Remove the insulating 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. This ensures a reliable connection and protects the conductor from oxidation. Tips for preparing the cables are available in this article.
