MultiTransmitter Fibra is an integration module connecting third-party wired devices to an Ajax security system. It has 18 zones for connecting NC, NO, EOL, 2EOL, and 3EOL devices.
MultiTransmitter Fibra is equipped with two tampers for protection against dismantling. The device is powered from the 100–240 V~ mains, and can also be powered from the 12 V⎓ backup battery. It can supply 10.5–15 V⎓ power to connected devices.
The integration module is compatible with Hub Hybrid (2G) and Hub Hybrid (4G). Connection to other hubs, radio signal range extenders, ocBridge Plus, and uartBridge is not provided.
MultiTransmitter Fibra works as part of an Ajax security system, exchanging data with the hub using the secure Fibra wired protocol. The wired connection range is up to 2,000 meters when using a U/UTP cat.5 twisted pair.
MultiTransmitter Fibra is a product of the Fibra wired lineup. The installation, sale, and administration of these devices are performed only by accredited Ajax partners.

Operating principle
MultiTransmitter Fibra is designed to integrate third-party wired devices into an Ajax security system. The integration module receives information about alarms, malfunctions, and events from devices through a wired connection. After that, it sends the event to Hub Hybrid using the Fibra data transfer wired protocol. And Hub Hybrid sends messages to users and the security company CMS (central monitoring station).
MultiTransmitter Fibra is used to integrate alarm and auxiliary request alert buttons, indoor and outdoor motion detectors. As well as detectors that track opening, vibration, glass breaking, fire, gas and water leakage, etc.
Also, you can set up KeyArm Zone that allows switching system arming modes with a third-party device connected to MultiTransmitter Fibra. KeyArm allows you to arm/disarm the system, individual groups, or manage Night Mode.
The KeyArm feature is supported by all hubs (except Hub model) with OS Malevich 2.17 and higher.
The device type is specified in the settings of the zone to which the wired detector or device is connected. The selected type determines the text of alarm messages and events of the connected device, as well as event codes transmitted to the CMS.

Wired devices connection types
- NO (normally open).
- NC (normally closed).
- EOL (connection with one resistor).
- 2EOL (connection with two resistors).
- 3EOL (connection with three resistors).
In the Ajax app, you can select the normal state (normally open or normally closed) for each of the terminal pairs: alarm, tamper, and malfunction terminals. This allows connecting any potential-free (“dry”) contact detector of any configuration to MultiTransmitter Fibra.
Fibra communication protocol
The integration module uses Fibra technology to transmit alarms and events. This is a two-way wired data transfer protocol that provides fast and reliable communication between the hub and integration module. Using the bus connection method, Fibra delivers alarms and events instantly, even if 100 devices are connected to the system.
Fibra supports block encryption with dynamic key and verifies each communication session with devices to prevent sabotage and spoofing. The protocol provides for regular polling of devices by the hub at a specified frequency to control communication and display the state of system devices in Ajax apps.
Sending events to the Central Monitoring Station (CMS)
An Ajax security system can transmit alarms to the PRO Desktop monitoring app as well as the Central Monitoring Station (CMS) using SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other proprietary protocols.
MultiTransmitter Fibra can transmit the following events:
- MultiTransmitter Fibra tampers alarm/restoration.
- Connected devices alarm/restoration.
- Loss/recovery of communication between MultiTransmitter Fibra and hub.
- Disabling/enabling MultiTransmitter Fibra.
- Disabling/enabling wired detectors and devices connected to MultiTransmitter Fibra.
- Unsuccessful attempt to arm the system (if system integrity check is enabled).
When an alarm is received, the monitoring station operator of the security company 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 and the CMS. The list of transmitted parameters may differ depending on the type of the CMS and the selected communication protocol.
The ID and number of the loop (zone) of the integration module and connected devices can be found in their States in Ajax apps. To check the loop (zone) number, open the States of the integration module or the connected wired device. The device number corresponds to the loop (zone) number.
Selecting the installation place
MultiTransmitter Fibra integration module is mounted on a vertical surface with the bundled screws. All the necessary holes for fastening in the casing have already been made. MultiTransmitter Fibra is designed for indoor installation only.
Vertical fixation of the integration module is needed for the tamper to respond if someone tries to detach a device. Learn the battery documentation before installing — some batteries can be mounted only vertically (with terminals upward). Another installation position could cause fast battery degradation.
It is advisable to choose an installation site where the hub is hidden from prying eyes — for example, in the storage room. This helps to reduce the risk of sabotage of the integration module and devices connected to it.
Selecting the installation site for MultiTransmitter Fibra, take into account the parameters that affect the operation of the device module:
- Fibra signal strength.
- Cable length for connecting MultiTransmitter Fibra.
- Cable length for connecting wired devices to MultiTransmitter Fibra.
Consider the placement recommendations when designing the security system project for your object. The security system should be designed and installed by professionals. The list of authorized Ajax partners is available here.
Where it is forbidden to install MultiTransmitter Fibra
- Outdoors. This can lead to the failure of the integration module.
- Inside premises with temperature and humidity values that do not correspond to the operating parameters. This can lead to the failure of the integration module.
- In places where the integration module has an unstable or low signal strength. This can lead to a connection loss between the hub and the integration module.
Fibra signal strength
The Fibra signal level is determined by the number of undelivered or corrupted data packages over a certain period. 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 connected to one Fibra line.
- Cable length and type.
- The correctness of the wire connections to the terminals.
Designing the project
It is essential to properly design the security system to install and configure security system devices correctly. The design must take into account the number and types of devices at the object, their exact location and installation height, the length of Fibra wired lines, the type of cable used, and other parameters.
Tips for designing Fibra wired systems are available in this article.
Topologies
At the moment, Ajax security systems support two topologies — Beam (Radial wiring) and Ring.
Beam connection (Radial wiring) occupies one Fibra line of the hub. Only the segment that remains physically connected to the hub will function in the event of a line break. All devices connected after the breakpoint will lose connection with the hub.
Ring connection occupies two Fibra lines of the hub. If the ring breaks in one place, no device will be disabled. The ring reconfigures into two lines, which continue to operate normally. Users and security company will receive notification about the break.
| Beam (Radial wiring) | Ring |
|
|
Both device connection topologies can be built on the same hub. For example, you can use two Ring connections and four Beam (Radial) connections.
Different types of devices can be connected to a single Fibra line. For example, you can connect opening detectors, motion detectors with photo verification support, sirens, and keypads to the same line at the same time.
The devices are connected to the Fibra line one after another, as shown in the diagram. Branching of lines is not allowed.
For the Beam (Radial) topology, be sure to install a 120 Ohm terminating resistor at the end of the line (included in the hub complete set). The terminating resistor is connected to the signal terminals of the last detector on the line.
Cable length and type
For MultiTransmitter Fibra
The maximum range of a wired connection using the Beam (Radial) topology is 2,000 meters, and using the Ring topology — 500 meters.
Recommended cable types:
- U/UTP cat.5 4 × 2 × 0.51, copper conductor.
- Signal cable 4 × 0.22, copper conductor.
If you use a different type of cable, the communication range for wired connections may vary. No other types of cables have been tested.
For wired devices of third-party manufacturers
The maximum cable length for connecting third-party devices to MultiTransmitter Fibra is 400 meters.
Recommended cable types:
- Signal cable 4 × 0.22, copper conductor.
- Signal cable 4 × 0.22, conductor material is aluminum covered with copper.
If you use a different type of cable, the communication range for wired connections may vary. No other types of cables have been tested.
Verification using a calculator
To make sure that the project is calculated correctly and that such a system will work in real practice, we have developed a Fibra power supply calculator. The calculator helps to check the quality of communication and cable length for wired Fibra devices with the selected configuration at the system design stage.
Additional information
The maximum current that Hub Hybrid can supply in total for all Fibra lines is 600 mA. Please note that the total current consumption of the devices in the system depends on the type of cable, its length, the type of connected device, the quality of the connection of conductors, and other factors. Therefore, after selecting devices, we recommend verifying the project using the Fibra power supply calculator.
Up to 100 devices can be connected to Hub Hybrid at default settings. Each device connected to MultiTransmitter Fibra also occupies one slot within the device limit of the hub.
MultiTransmitter Fibra supports EOL resistors with resistance from 1 to 15 kOhm. The total resistance of all resistors is up to 30 kOhm. To increase anti-sabotage protection, use EOL resistors with different resistances in one detector. The recommended resistance ratio of EOL resistors: R1＝R, R2＝2·R, R3＝3·R.
The integration module has four 10.5-15 V⎓ power supply lines: one for the fire detectors and three — for other devices.
After an alarm, fire detectors require a power reset to restore the normal operation mode. Therefore, the fire detectors power supply should only be connected to a dedicated line. Also, avoid connecting other detectors and devices to power terminals of fire detectors as this may lead to false alarms or incorrect operation of the devices.
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.
It is safest to route cables inside walls, floors, and ceilings: this way they will be invisible and unavailable for intruders. It also ensures their greater durability — the cable will be affected by fewer external factors affecting the conductor’s natural wear and insulating layer.
As a rule, security system cables are laid during the construction or repair stage and after wiring at the object.
If impossible to install cables inside the walls, route them so that the cable is sufficiently protected and hidden from prying eyes. For example, in a cable tray or a protective corrugated pipe. It is recommended to hide them. For example, behind the furniture.
We recommend using protective pipes, cable conduits, or corrugated pipes to protect cables, regardless of whether they are routed inside the wall or not. The cables should be arranged carefully: no sagging, tangling, or twisting is allowed.
Take into account the places of possible signal interference. If the cable is routed near motors, generators, transformers, power lines, control relays, and other sources of electromagnetic interference, use twisted-pair cable in these areas.
Cable routing
When laying cables for a security system, you need to know not only the general requirements and rules for electrical installation work but also the specific installation features of each device: installation height, mounting method, how the cable is inserted into the enclosure, and other parameters.
Before installation, we recommend you read the Selecting the installation site section of this manual, as well as the manual for a third-party wired device. If you have questions about the operation of third-party wired devices, please contact the technical support of the manufacturer of this device.
Try to avoid any deviations from the security system project design. Violation of the basic installation rules and recommendations of this manual, as well as the instructions of the manufacturer of third-party wired devices, may lead to incorrect operation of the integration module, false alarms of connected wired devices, and loss of connection with MultiTransmitter Fibra.
Check the cables for bends and physical damage before installation. Replace the damaged cables.
Signal cables of Fibra devices must be laid at a distance of at least 50 cm from the power cables when lying parallel, and, if they intersect, it must be at a 90° angle.
Observe the permissible bend radius of the cable. It is specified by the manufacturer in the cable specifications. Otherwise, you risk damaging or breaking the conductor.
Fibra devices are connected to the line one after another. Branching of lines is not allowed.
Preparing cables for connection
Remove the insulating layer of the cable and strip the cable with a special insulation stripper. It strips the cable properly without damaging the conductor. The ends of the wires that will be inserted into the detector’s terminals should be tinned or crimped with a sleeve. This ensures reliable connection and protects the conductor from oxidation.
Recommended cable lug sizes: 0.75 to 1 mm².
Features of enclosures of third-party wired devices may exclude the use of insulated ferrules. To connect such devices, you can use a wire-end ferrule without insulation with a cross-section of 0.5 mm² or more.
Installation and connection
Before installing MultiTransmitter Fibra, make sure that you have selected the optimal location and that it meets the requirements of this manual. To reduce the risk of sabotage, the ables must be hidden from view and located in a difficult place for intruders to access. Ideally, the cables should be mounted in walls, floors, or ceilings. Run the Fibra signal strength test before final installation.
When connecting to the terminals of the device, do not twist the wires together, but solder them. The ends of the wires that will be inserted into the terminals should be tinned or crimped with a special sleeve. This will ensure a reliable connection. Observe the safety procedures and the rules for electrical installation work when connecting the integration module and third-party devices.
