HomeSiren Fibra User Manual

Updated

HomeSiren Fibra is a wired siren for indoor installation. The device notifies on events and alarms with an LED indicator and sound volume up to 105 dB. Supports connection of an additional wired LED.

The siren 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. Integration with other security systems is not provided either.

HomeSiren Fibra works as part of an Ajax security system, exchanging data with the hub using the secure Fibra wired communication protocol. The connection range is up to 2,000 meters when using the U/UTP cat.5 twisted pair.

HomeSiren Fibra is the product of the Fibra lineup. Only accredited Ajax partners can install, sell and administer these products.

Operating principle

HomeSiren Fibra is a wired indoor siren.

The siren performs two tasks:

  1. Informs about an alarm. The siren responds to tamper and security system alarms in less than a second. It is loud enough to scare away intruders and attract the neighbors’ attention.
  2. Reports the security status. The siren uses LED indication to notify that the object is armed, and reports about Delays When Entering/Leaving with sound. These functions can be helpful when managing the security system using key fobs and keypads: the siren reminds you to disarm the system when you enter the object.

Adjust the siren volume and duration in the app. In case of an alarm, the buzzer can work for 3 to 180 seconds with a sound volume of 81 to 105 dB. In the Ajax app you can specify which detectors will activate the siren. 

It is not easy to disable and dismantle a triggered siren if properly installed. The device has a robust enclosure and a protected buzzer. The siren is equipped with a tamper button for additional protection. It triggers when someone tries to open the enclosure or tear the device off the surface.

Fibra communication protocol

The siren uses Fibra technology to transmit alarms and events. The protocol provides fast and reliable two-way wired communication between the hub and the connected devices. 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 a dynamic key and verifies each communication session with devices to prevent sabotage and spoofing. The protocol provides a regular “hub—sirens” polling with a set frequency to monitor connection and display the device statuses in the Ajax apps in real time.

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) using SurGard (Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other proprietary protocols. The list of supported protocols is available here.

HomeSiren Fibra can transmit the following events:

  1. Tamper alarm/recovery.
  2. Loss/recovery of connection between HomeSiren Fibra and the hub.
  3. Temporary activation/deactivation of HomeSiren Fibra.
  4. Unsuccessful attempt to arm the system (with the system integrity check 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 location (room, group) can be transmitted to PRO Desktop and the CMS.  The list of transmitted parameters may differ depending on the type of CMS and the selected communication protocol.

Check the device ID, loop (zone) number, and bus number in device states in the Ajax app.

Selecting the installation site

When choosing where to place HomeSiren Fibra, take into account the parameters that affect the operation of the device:

  • Fibra signal strength.
  • Cable length for connecting HomeSiren Fibra.
  • Audibility of HomeSiren Fibra.
  • Visibility of HomeSiren Fibra LED indication.
  • Cable length for connecting a third-party LED.

HomeSiren Fibra is mounted on a vertical surface with the bundled screws. The siren is designed for indoor installation only.

The recommended installation height is 2.5 meters or more. This will make it harder for intruders to access the device in case of an attempted sabotage. If the siren cannot be placed at this height, it can be installed lower.

Consider these 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.

Do not install HomeSiren Fibra

  • Outdoors. This could damage the siren.
  • In places where the audio signal of the siren can be jammed. For example, inside a closet or behind thick curtains. This reduces the effectiveness of the siren operation.
  • In rooms with temperature and humidity that do not correspond to operating parameters. This could damage the siren.
  • In places where the siren has an unstable or low signal strength. This can lead to a loss of connection between the hub and the siren.
  • Near glass break detectors. This can cause the glass break detector false alarms.

Fibra signal strength

The Fibra signal level is determined by the number of undelivered or corrupted data packages over a certain period. The icon  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 detectors connected to one Fibra line.
  • Cable length and type.
  • The correctness of wire connections to the terminals.

Project designing

To correctly install and configure security system devices, it is important to properly design the security system project. The design 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.

Designing tips for wired Fibra systems are available in this article.

Topologies

Ajax security systems support two topologies: Beam (Radial wiring) and Ring.

Connecting devices using the Ring topology will be implemented in the next OS Malevich updates. Hardware update of Hub Hybrid is not required.

Beam connection (Radial wiring) occupies one bus output 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.

ajax glassprotect fibra

Ring connection takes two bus outputs 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.

ajax glassprotect fibra
Beam (Radial wiring) Ring
  • takes one bus output of the hub
  • up to 8 beams with the same hub
  • up to 2,000 m of wired communication for the same line
  • a terminating resistor is installed at the end of the line
  • takes two bus outputs of the hub
  • up to 4 rings with the same hub
  • up to 500 m of wired communication for the same ring
  • no terminating resistor is needed at the end of the line

Both topologies can be used 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 the same Fibra line. For example, you can connect opening detectors, motion detectors with photo verification, sirens, and keypads to the same line. 

The devices are connected to the Fibra line one by one, as shown on the diagram. Line branching is not supported.

ajax glassprotect fibra

When using 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.

ajax glassprotect fibra

Cable length and type

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 wired connection range 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 the Fibra power supply calculator (in progress). The calculator helps to check the communication quality and cable length for wired Fibra devices with the selected configuration when designing the system project.

Additional information

The maximum current that Hub Hybrid can supply in total for all Fibra lines is 600 mA. 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 (in progress).

Up to 100 devices can be connected to Hub Hybrid by default. Each device connected to HomeSiren Fibra also occupies one slot within the device limit of the hub.

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 natural wear of the conductor and its 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, take into account 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 any 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 siren, false alarms of connected wired devices, and loss of connection with HomeSiren 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 laying parallel and, if they intersect, at a 90° angle.

Observe the permissible bend radius of the cable. It is indicated by the manufacturer in the cable specifications. Otherwise, you risk damaging or breaking the conductor.

Fibra devices are connected to the line one by one. Line branching is not supported.

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 tips. This ensures reliable connection and protects the conductor from oxidation. 

Recommended cable lug sizes: 0.75 to 1 mm².

Installation and connection

Before installing HomeSiren 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 cables must be hidden from view and located in a place that is difficult for intruders to access. Ideally, run the cables in the walls, floors, or ceilings.

When connecting to the device terminals, do not twist the wires together; solder them. The ends of the wires that will be inserted into the terminals should be tinned or crimped with special tips. This will ensure a reliable connection. Observe safety procedures and regulations for electrical installation work when connecting the device.

Connecting HomeSiren Fibra to the hub

  1. Remove the SmartBracket mounting panel from the siren. To do this, lightly press the panel and slide it down.
  2. Remove the HomeSiren Fibra board from the holders on the mounting panel by pulling them apart.
  3. Prepare holes for cable output in advance. To output cables from the back of the siren, carefully break out the perforated parts on the SmartBracket mounting panel. To output cables from the bottom of the siren, make a hole in the bottom of the enclosure using a drill, a special milling cutter for small holes, or hand-cutting tools.
