Design security systems freely with LineSplit Fibra

LineSplit brings a new level of flexibility into the installation process. There is no need to replace wiring if you want to replace an outdated security system with Ajax. The module can be installed at any point of the Fibra line (even after another LineSplit(1)). It splits one Fibra line into four and extends each one of them by 2,000 m(2). LineSplit inherits all the advantages of Ajax smart devices: it is easy to control the module from the app, receive event notifications, and configure or test LineSplit remotely.

Devices compatibility

This is the wired device of the Fibra product line. Only accredited Ajax Systems partners can sell, install, and administer Fibra products.

One device, two missions

More freedom in installation

More freedom in installation

LineSplit provides enhanced flexibility during the installation of a security system. Devices can be installed safely, reducing cable and installation costs. LineSplit can also provide a separate line for each connected device.

An installer can run a single cable to LineSplit to cover different rooms with separate lines and then run the cables to other rooms. Without LineSplit, an installer would have to run a cable directly from the hub for each line. This makes the system and its installation more complex and, consequently, more expensive.

Renovating outdated wired system

Renovating outdated wired system

You can replace a legacy security system with Ajax without replacing wiring. Old devices are replaced with Fibra devices. And the already installed cables and their topology can be reused – whether in bus or analog systems.

If the system already has splitters installed, the appropriate number of the LineSplit modules is installed at the required points. It saves installers time and money on laying new cables.

Easy to mount into Case

LineSplit is inserted into Case. This casing has an optimal arrangement of wire channels, special holders for the module, and the tamper. Several variations of casings are available.

You can mount one LineSplit module into Case or fit several devices. The required minimum number of casings can be selected for the facility's needs, which saves the budget and speeds up the installation of the security system.

Unique wired technology

Fibra is a protocol to ensure fast and secure two-way wired communication between the hub and connected devices. Fibra delivers instant data-rich notifications: security companies and users know which device was triggered, when, and where it happened.


Encrypted two-way communication

Connect any Fibra device to the line

Fibra line extension up to 2,000 m(2)

Energy efficiency as a priority

The module consumes up to 0,22 W at peak consumption times. With such low power consumption, an installer can connect more devices to a Fibra line and lengthen the wired connectivity.

Fibra communication follows the TDMA principle. Each device has a short time frame to exchange data with a hub. The rest of the time, their communication modules are inactive. This significantly reduces power consumption and helps avoid interferences even when multiple devices communicate simultaneously.

LineSplit consumption is up to 0,22 W

The casing where LineSplit is installed has a tamper that warns a monitoring company and system users about an attempt to open Case or remove the device from the mounting panel.

Protection against short circuits

Protection against short circuits

Fibra protocol and a special digital algorithm provide reliable protection against unnoticed short-circuiting of the module. If someone tries to short-circuit it, it notifies of a malfunction. Hub informs both the Central Monitoring Station (CMS) and users about the incident.

Encryption of transmitted data

Encryption of transmitted data

All data the system stores and transmits is protected by block encryption with a dynamic key. Encryption makes it extremely difficult to connect to the module with the intention of sabotage.

Device authentication against spoofing

Device authentication against spoofing

The hub checks the device's unique parameters for authentication during each communication session. If any parameter fails the check, the hub ignores device commands.

Communication failure detection

Communication failure detection

The device regularly exchanges data with the hub. With minimal polling settings (3 data packages in 12 seconds), it takes 36 seconds to identify communication loss and notify the security company and users about the incident.

Event notifications

Event notifications

The monitoring station instantly receives notifications on events. The information includes time, device type and name, event type, and location room(5).

Convenient to work for PROs

Installing a wired system is always a challenge. We have taken care of the quick installation of LineSplit Fibra. The module is installed into Case and can be mounted in just a few minutes. With few clicks, it can be paired with the hub in the apps for iOS, Android, macOS, and Windows. Installers can configure the device remotely in the Ajax apps.

LineSplit Fibra is installed into Case, which has an optimal arrangement of channels for wires, special holders for the module, and the built-in tamper module. There are several variations with different sizes of casings. Installation kit with dowels and screws included. No tools are required to install LineSplit into Case.

Installation into Case

Jumper included

Hassle-free installation

Installers can add a module in two ways: automatically scanning lines or scanning a QR code. When scanning lines, there are two ways to identify the desired device: by clicking in the app or tamper activating. When an installer adds a device, it will immediately have a default name and settings are suitable for most cases.

Forget about configuring via the keyboard. All testing and configuration are performed in mobile and desktop Ajax apps. An installer can work both on behalf of the company and as a sole installer.

With proprietary protocols, any Ajax system can transmit alarms to the PRO Desktop monitoring app and third-party CMS.When an alarm is received, the monitoring station operator knows what happened and where the rapid response unit has to be sent. All Ajax devices are addressable, so events, the device type, its assigned name and room can be transmitted to PRO Desktop or third-party monitoring software.

1 — Up to 10 LineSplit Fibra modules can be installed one after the other, connecting each module to the output line of the previous one.

2 — When using a twisted pair cable UTP cat. 5. Other cables may have different values. Fibra power supply calculator

3 — LineSplit Fibra does not provide additional power supply to the line.

4 — Notification of attempts to break or open Case. Case is sold separately.Case has a tamper module connected to the LineSplit terminal (indicated as TAMPER on a device board). LineSplit itself does not have a tamper. Learn more about Case

5 — The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.
