MultiTransmitter Fibra User Manual

Updated

MultiTransmitter Fibra is an integration module with 18 wired zones for connecting third-party detectors and devices to the Ajax security system. Supports NC, NO, EOL, 2EOL, and 3EOL devices.

MultiTransmitter Fibra is equipped with two tampers that protect against lid opening and detaching from the surface. The device is powered from the 110–240 V~ mains, and can also run on a 12 V⎓ backup battery. It can supply 10.5–15.0 V⎓ power to connected detectors.

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 only works as a part of the Ajax security system, communicating with the hub via secure Fibra protocol. The wired connection range reaches 2000 meters when connected via twisted pair U/UTP cat.5.

MultiTransmitter Fibra is the device of the new Fibra wired product line. Such devices can only be purchased, installed and administered by accredited Ajax partners.

Operating principle

MultiTransmitter Fibra is designed for integrating third-party wired detectors and devices into the Ajax security system. The integration module receives information about alarms, events and malfunctions from detectors and devices via a wired connection. Then the integration module transmits the event to Hub Hybrid using the Fibra wired data transfer protocol. Hub Hybrid sends notifications to users and to the Central Monitoring Station (CMS) of the security company.

ajax multiyransmitter fibra

MultiTransmitter Fibra can be used for integration of panic and medical alert buttons, indoor and outdoor motion detectors, as well as opening, vibration, breaking, gas, fire detectors, etc.

The device type is indicated in the settings of the zone to which the wired detector/device is connected. The selected type determines the text of notifications about alarms and events of the connected device, as well as event codes transmitted to the Central Monitoring Station (CMS) of the security company.

A total of 7 types of events are available for the devices connected to MultiTransmitter Fibra:

Malfunction Chapter in progress

MultiTransmitter Fibra has 18 wired zones. Multiple devices can be connected to one zone. The number of connected devices depends on their power consumption. The total maximum consumption of the devices or detectors connected to all zones is 1 A.

The integration module has 3 power supply lines of 12 V⎓: one separated line for fire detectors and two lines for other devices.

After the fire alarm, fire detectors need a power reset to restore normal operation. Therefore, the power supply of fire detectors should only be connected to a separate line. 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.

Supported 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 (NC or NO) for each terminal pair: panic, tamper, and malfunction. This allows connecting to MultiTransmitter Fibra any detector with “dry” contacts, regardless of its configuration.

Fibra data transfer 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 the rest of the devices. Using the bus connection method, Fibra delivers alarms and events instantly, even if 100 detectors are connected to the system.

Fibra supports floating key block encryption and verifies each communication session with devices to prevent sabotage and forgery. The protocol requires regular polling of sirens and detectors by the hub with a predetermined frequency to monitor connection and display the status of the system devices in real time in the Ajax apps.

Sending events to the monitoring station

The Ajax security system can transmit alarms to the PRO Desktop monitoring app as well as the central monitoring station (CMS) in the formats of the SurGard (Contact ID), SIA (DC-09), ADEMCO 685 and other proprietary protocols. A complete list of supported protocols is available here.

MultiTransmitter Fibra can transmit the following events:

  1. MultiTransmitter Fibra tamper alarm / recovery.
  2. Alarms of connected devices.
  3. Loss / restoration of connection between MultiTransmitter Fibra and the hub.
  4. Loss / restoration of connection with the devices connected to MultiTransmitter Fibra.
  5. Temporary deactivation / activation of MultiTransmitter Fibra.
  6. Temporary deactivation / activation of wired detectors and devices connected to MultiTransmitter Fibra.
  7. Unsuccessful attempt to arm the security system (with enabled integrity check of the system).

When an alarm is received, the operator of the security company monitoring station knows exactly what happened and precisely where to send a fast response team on the site. Addressability of each Ajax device allows you to send not only events to the PRO Desktop or to the CMS but also the type of the device, the name of the device, and the virtual room to which the detector is assigned. Note that the list of transmitted parameters may differ depending on the type of CMS and the selected protocol for communication with the monitoring station.

The integration module ID and the loop (zone) number can be found on its States in the Ajax app. To learn the loop (zone) number, open the States screen of the integration module or the connected wired device or detector. The device number corresponds to the loop (zone) number.

MultiTransmitter Fibra placement

When choosing where to place MultiTransmitter Fibra location, consider the parameters affecting the correct operation of the integration module:

  • Fibra signal strength.
  • Connection cable length for MultiTransmitetr Fibra.
  • Connection cable length for wired detectors and devices connected to MultiTransmitter Fibra.

Consider the placement recommendations when designing your facility’s security system. Design and installation of the security system should be carried out by professionals. A list of authorized official Ajax partners is available here.

MultiTransmitter Fibra can be mounted on a vertical surface with bundled fasteners. All the necessary holes for mounting are already made.

ajax multiyransmitter fibra

We recommend choosing the installation place where the integration module is hidden from the burglar’s eyes, for example, in the storeroom. This will help to reduce the possibility of sabotage. Please note that MultiTransmitter Fibra is intended for indoor installation only.

Design and preparation

For the system to work correctly, it is important to properly design the project and install the integration module, as well as all the connected wired detectors and devices. Read the manual for third-party wired detectors and devices before installation. Be sure to follow this manual. If you have any questions, please contact the technical support of the detector or device manufacturer.

Violation of the basic installation rules and recommendations of this manual, as well as the manual for third-party wired detectors and devices may lead to incorrect operation of the integration module, false alarms of connected wired devices, or loss of connection with MultiTransmitter Fibra.

When designing the layout scheme of the detectors, consider the wiring diagram of the power cables laid on the site. Signal cables 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. Note that, if you connect multiple devices on the same bus, detectors are connected in sequence.

Note that Fibra detectors and devices are connected sequentially end-to-end in a line if you connect multiple devices to the same hub bus.

The maximum number of connectable devices for the Hub Hybrid is 100 at the default settings, including wired detectors and devices connected to MultiTransmitter Fibra.

How to calculate the number of detectors to be connected (in progress)

For facilities that are under construction or renovation, cables are laid after the main wiring of the facility. Use protective tubes to route system cables to organize and secure the wires; ties, clips, and staples can be used to secure them.

When laying wires externally (without mounting them inside the walls), use an electric channel raceway. Raceways should be no more than half-filled with cables. Do not allow cables and wires to sag. The raceway should be hidden from view if possible — for example, behind furniture.

We recommend laying cables inside walls, floors, and ceilings. This will provide greater security: the wires will not be visible, and it will be impossible for an intruder to access them.

When selecting a cable, consider the length of the connecting lines and the number of detectors connected to the line; those parameters affect signal strength. We recommend using shielded copper cables with a high-quality insulating layer.

When installing, observe the bend radius that the manufacturer specifies in the cable specs. Otherwise, you risk damaging or breaking the conductor.

Be sure to check all cables for bends and physical damage before installation. Perform the installation in a way that minimizes the possibility of damage to the cables from the outside.

Signal strength and wire length

The Fibra signal level is determined by the number of undelivered or corrupted data packages over a certain period. The icon on 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.

The signal strength is influenced by the following factors: the number of devices connected to one bus, the length and type of cable, and the proper connection of the wires to terminals.

Check Fibra signal strength before the final installation of the devices. In case of one or zero bar signal strength, we cannot guarantee stable operation of the device.

The maximum permissible cable length depends on its type, material, and the method of connecting the devices. When connected using the Star connection method with a twisted pair U/UTP cat.5 (4×2×0.51), the wired connection length can be up to 2,000 meters.

When devices are connected using the Ring connection method, the maximum cable length is 500 meters when using a twisted pair.

Connecting devices using the Ring connection method will be available with future OS Malevich updates. Hardware update of Hub Hybrid won’t be required.

The maximum length of the signal cable used to connect third-party devices or detectors to MultiTransmitter Fibra is 400 meters (the copper-plated aluminum cable with 0.22 sq mm cross-section). The value may vary if a different type of cable is used. No other types of cable have been tested.

Do not install MultiTransmitter Fibra

  1. Outdoors. This may damage the integration module.
  2. Inside premises with temperature and humidity outside the permissible limits. This could damage the integration module.
  3. In places where the integration module has 0 or 1 bar of Fibra signal. This could result in the loss of connection between the hub and the integration module.

Installation and connection

Before installing MultiTransmitter Fibra, make sure that you have chosen the optimal location and that it meets the conditions of this manual. The wires must be hidden from the burglar’s eyes in an inaccessible place inaccessible to reduce the possibility of sabotage. If possible, the wires must be hidden inside the walls, floor or ceiling. Run Fibra Signal Strength Test before final installation.

When connecting the integration module, do not twist the wires together; solder them. The ends of the wires which will be inserted into the integration module terminals should be tinned or crimped with a special sleeve. This will ensure a reliable connection. Follow safety precautions and electrical installation rules when connecting the integration module and third-party devices and detectors.

How to connect MultiTransmitter Fibra to the hub

  1. Disconnect the external power supply and the backup battery of the hub.

    ajax multiyransmitter fibra
  7. If MultiTransmitter Fibra is not the last in the connection line, prepare and wire the cable for the next device into MultiTransmitter Fibra terminals in advance. If the integration module is the last in the line, install a terminating resistor at the end of the connecting line in case of the Star connection topology. With the Ring connection topology, a terminating resistor is not required.

    We recommend connecting devices via the Ring connection method (hub – detector – hub), because, if the line is broken, the devices will be connected via the Star connection method and will continue to transmit events to the hub. Notification about the Ring failure will be sent to users and the security company. Ring network connection will be implemented in the next updates of OS Malevich. Hardware update won’t be required.

    ajax multiyransmitter fibra
  8. Secure the casing with the bundled screws on the vertical surface at the chosen installation place. When mounting, use all the fixing points available on the casing. One of them, in the perforated part of the mount above the tamper, is necessary for tamper triggering in case of any attempt to detach MultiTransmitter Fibra from the surface.
  9. Install a 12 V⎓ backup battery on the special holders in the casing. Note that third-party power supplies cannot be connected to the terminals.

    Use a 12 V⎓ battery with a capacity of 4 or 7 A⋅h. You can also use similar batteries of a different capacity if their size fits the casing and the maximum full charge time doesn’t exceed 30 hours. The maximum overall battery dimensions is 150 × 65 × 94 mm with weight up to 5 kg.

  10. Connect the backup battery to the terminals according to the diagram below using the bundled connection cable. Follow the polarity of wire connection. Securely fix the wires in the terminals.
    ajax multiyransmitter fibra
  11. Turn on the hub.

Measure the detector resistance Launches the assistant to automatically measure the resistance of the resistor connected to the detector.
Type of event Selecting the event type of the connected detector or device:

  • Intrusion
  • Fire
  • Medical help
  • Panic button
  • Gas
  • Tamper

The text of notifications in the event feed and SMS, as well as the code transmitted to the CMS depend on the selected type of event.

Detector Type Type of connected detector or device:

  • Pulse — for example, a motion detector. After an alarm, a recovery event will not be sent if the detector returns to the normal state.
  • Bistable — for example, an opening detector. After an alarm, a recovery notification will be sent when the detector returns to the normal state.

Make sure to set the type matching the connected detector.

  • 20 msec
  • 100 msec (default value)
  • 1 sec

An alarm is triggered if the pulse from the detector exceeds the specified time.

It can be used as a false alarm filter.

Alert with a siren if alarm is detected If enabled, the sirens added to the system are activated in case an alarm is detected.
Alert with a siren if a contact is lost or shorted out If enabled, the sirens added to the system are activated when a broken or shorted out contact is detected.

How to set Chime
What is Chime

Temporary deactivation

Allows to disable the device without removing it from the system.

Two options are available:

  • No — the device or detector operates normally and transmits all events.
  • Entirely — the device will not execute commands or participate in automation scenarios. The system will ignore device alarms and other events.

Learn more about temporary deactivation of devices

The system can also automatically deactivate devices when the set number of alarms is exceeded or when the recovery timer expires.

Auto deactivation of devices is configured in the Service menu in the hub settings.

Unpair device Unpairs the wired detector or device from the hub and deletes its settings.

How to set Chime

Chime is a sound signal Ajax sirens that notifies about the opening detector trigger when the system is disarmed. The feature is used, for example, in stores to notify employees that someone has entered the building.

Notifications are configured in two stages: setting up, the opening detectors and setting up the sirens.

Setting up a wired opening detector connected to MultiTransmitter Fibra

Before setting up the Chime feature, make sure that a wired opening detector is physically connected to MultiTransmitter Fibra and the following options have been configured in the detector settings in the Ajax app:

  • Input type: Detector.
  • Type of event: Intrusion.
  • Work mode: Normally closed.
  • External detector type: Bistable.
  • Pulse time: set the required time to protect the detector from rattling.

Detector settings:

  1. Go to the Devices tab.
  2. Find MultiTransmitter Fibra in the list.
  3. Click Devices under the MultiTransmitter Fibra status icons.
  4. Select the opening detector from the list.
  5. Go to Settings by clicking the icon .
  6. Go to the Chime Settings menu.
  7. Enable If an external contact is open.
  8. Select the chime sound: 1 to 4 short beeps. Once selected, the Ajax app will play the sound.
  9. Click Back to save the settings.
  10. Set up the required siren.

MultiTransmitter Fibra functionality test

Ajax security system provides several types of tests that help you make sure that device’s installation place is chosen correctly. The tests do not start immediately but not later than over a single hub–detector polling period which sets automatically depending on the number of devices connected to the hub.

For MultiTransmitter Fibra the Fibra Signal Strength Test is available.

To run a test in the Ajax app:

  1. Select the hub (if you have several of them or if you are using the PRO version of the app).
  2. Go to the Devices tab.
  3. Choose MultiTransmitter Fibra.
  4. Go to Settings .
  5. Select Fibra Signal Strength Test.
  6. Run the test.

MultiTransmitter Fibra maintenance

Check the functionality of the integration module and the connected wired devices on a regular basis. The optimal interval for the check is once every three months. During the check, it is necessary to verify the correctness of the wire connection to the integration module terminals.

Clean the casing from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth that is suitable for equipment care. Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to clean the device.
