Operating principle

StreetSiren Fibra is a wired siren of the Ajax system. The device is equipped with a piezoelectric buzzer for sound alerting and an LED frame for visual alerting. The siren has a sealed battery that is used to power the device. The battery is charged from the Fibra line and is used for indication as well as for notification of alarms and events.

In case of the Fibra line damage or an emergency power shortage, the backup battery will provide the siren with power to indicate and alert alarms and events.

Siren performs four tasks:

1. Informs about alarms. The siren responds to tamper triggering and system alarms, including a buzzer and LED backlight in less than a second, which scares off intruders and attracts attention.

2. Indicates the security status. The siren uses LED indication to notify that the object is armed, and reports about Delays When Entering/Leaving with sound and backlight. These functions will be useful when controlling the system with key fobs and keypads. In this case, the siren can remind you to disarm the system when you enter the object.

3. Chime. Sirens with a special sound inform about the triggering of the opening detectors when the system is disarmed. The feature is used, for example, in stores, to notify employees that someone has entered the building.

4. Notifies of triggering until the system is disarmed. The lower right corner of the siren’s LED frame flashes after the sound signal is played. Thanks to this option, users and passing patrols of security companies can see that the system was triggered.

Alarm volume and duration

By alarm the siren sounds from 3 seconds to 3 minutes, emitting a sound volume of 85 to 113 dB. In the Ajax apps, you can set the duration and volume of the alarm, as well as determine which detectors will activate the siren. More details about this feature in the section settings.

Anti-sabotage protection

StreetSiren Fibra is equipped with a tamper button and raises the alarm when the main power is lost. The tamper button is triggered when the siren is removed from the mount or when the body is opened.

In the event of a sabotage, the users and the security company will know exactly which siren the intruders are trying to disable. The notifications contain the hub name (name of the guarded object), the incident time, the siren name, the alert type, and the virtual room to which the device is assigned.

StreetSiren Fibra has a pre-installed battery. It provides the siren with the power to indicate and notify of alarms and events in case of damage to the Fibra line or an emergency power shortage.

Fibra data transfer protocol

The siren uses Fibra technology to transmit alarms and events. This is a wired data transfer protocol that provides fast and reliable two-way 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 floating key and verifies each communication session with devices to prevent sabotage and spoofing. The protocol requires regular polling of devices by the hub with a predetermined frequency to monitor communication and display the status of the system devices in the Ajax apps.

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 proprietary protocols. The list of supported protocols is available here.

StreetSiren Fibra can transmit the following events:

1. Tamper alarm/recovery.
2. Alarm due to loss/restoration of the main power.
3. Loss/recovery of connection between StreetSiren Fibra and the hub.
4. Turning the siren off/on.
5. Battery discharge/charge.
6. Battery disconnection/connection.

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. Addressability of Ajax devices allows you to transmit to PRO Desktop and to the CMS events, device type, its assigned name and location (room, group). The list of transmitted parameters may differ depending on the type of CMS and the selected communication protocol.

Device ID, loop (zone) number, as well as line number can be found in its states.

Selecting the installation site

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

• Fibra signal strength.
• Cable length for connecting StreetSiren Fibra.
• Audibility of StreetSiren Fibra.
• Visibility of StreetSiren Fibra LED indication.

StreetSiren Fibra withstands heat, cold, and temperature drops. The siren is protected from rain and snow and can be installed on the facade of the building without a canopy. The siren enclosure has an IP54 protection class.

The recommended installation height is 2.5 meters or more. This raises difficulties for intruders to gain access to the device in the event of a sabotage attempt. If the siren cannot be placed at this height, it can be installed lower.

Follow placement recommendations when designing the Ajax system for an object. The security system should be designed and installed by professionals. The list of authorized Ajax partners is available here.

Do not install the siren

• Near glass break detectors. The siren sound may trigger an alarm.
• In places where the audio signal of the siren can be jammed.
• In places where the LED indication of the siren will not be visible.
• In places with low or unstable Fibra signal strength.

Fibra signal strength

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

Design

To correctly install and configure the system devices, it is important to properly design the system. 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. Tips for designing Fibra wired systems are available in this article.

Topologies

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

Beam connection (Radial wiring) occupies one line 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.

Ring connection occupies two line 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 the security company will receive notification of the break.

Both device connection 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 support, sirens, and keypads to the same line.

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

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 device in the line.

Cable length and type

The maximum communication range for wired connection using the Beam (Radial) topology is 2,000 meters, and that using the Ring topology is 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 connection may vary. No other types of cables have been tested.

Verification using a calculator

To make sure that the project is calculated correctly and such a system will work in practice, we have developed a Fibra lines distance 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

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, system cables are laid at the construction or repair stage, after the object has been wired.

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 conduit 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.

Consider the locations 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 system cables, take into account not only the general requirements and rules for electrical installation work, but also the specifics of the installation of each device: installation height, method of fastening, how the cable is inserted into the casing and other parameters.

Before installation, we recommend you read the Selecting the installation site section of this manual. Avoid deviations from the system project. Violation of the basic installation rules and the recommendations of this manual lead to incorrect operation, as well as loss of connection with the StreetSiren Fibra.

Check the cables for bends and physical damage before routing. Replace the damaged cables.

The signal cables for the system devices must be laid at a distance of at least 50 cm from the power cables when laid in parallel, and in case of their intersection, the angle must be 90°.

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.

Preparing cables for connection

Remove the insulating layer of the cable and strip the cable with a special insulation stripper only. It strips the cable properly without damaging the conductor. The ends of the wires that will be inserted into the terminals of the device must 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.

Installation and connection

Before installing the siren, make sure that you have selected the optimal location for the device and that it complies with 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, the cables should be set into the walls, floor, or ceiling. Before final installation, run the Volume Test and Fibra Signal Strength Test.

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 end sleeves. This will ensure a reliable connection. Follow safety procedures and regulations for electrical installation work.

Connecting StreetSiren Fibra to the hub

1. Turn off lines power in Ajax PRO app. The function is available in the lines menu:
   1. Hub → Settings → Lines → Lines Power Supply.
2. Plug the cable for the device connection into the hub casing. Connect the wires to the required hub line.
   

   

   +24V — 24 V⎓ power terminal.
   A, B — signal terminals.
   GND — ground.

3. Remove the SmartBracket mounting panel from the device and carefully break out the perforated part to output the cable from the backside. If it is necessary to output cable from the bottom or the side, make holes in the places indicated in the figure using a drill.
   

   

   1 — for cable output from the bottom of the siren.
   2 — for cable output through the wall.

4. If the siren is not the last device in the connection line, prepare a second cable in advance. The ends of the wires of the first and second cables that will be inserted into the terminals of the device should be tinned and soldered together.
5. Connect the wires to the terminals according to the figure below. Be sure to follow the polarity and connection order of the wires. Securely fasten the cable to the terminals. Secure the cable with ties.
   

   

   +24V — power
   А, B — signal terminals
   GND — ground

6. If the siren is the last device in the line and the Beam topology (Radial wiring) is used, install a terminating resistor by connecting it to the signal terminals of the device. When the Ring connection method is used, a terminating resistor is not needed.
7. Temporarily fix the SmartBracket panel to a vertical surface. This is necessary to run the device tests. The recommended installation height is 2.5 meters or more.
8. Install the device on the SmartBracket mounting panel.
9. Turn on lines power in the Ajax PRO app (Hub → Settings → Lines → Lines Power Supply). When power is applied, the LED will notify that the device is turned on.
10. Add StreetSiren Fibra to the system.
11. Run the Fibra Signal Strength Test. The recommended signal strength is two or three bars. If the signal strength is one or zero bars, check the connection correctness and the cable integrity.

    How to test operability in a correct way

12. Run the Volume Test. If the siren is hard to hear, change the volume or move the device.
13. If the device passes the tests, fix the SmartBracket mounting panel with bundled screws using at least two fixing points (one of them is in the perforated part of the mount above the tamper). When using other fasteners, make sure they do not damage or deform the mounting panel.
    

    Don’t use double-sided adhesive tape for temporary or permanent fixation of the siren, as the device may come off the surface at any time.

14. Put the device onto the SmartBracket mounting panel and fix it with the bundled screw.
15. Secure the siren with a screw. This reduces the risk of burglary and sabotage.

How to add StreetSiren Fibra

There are two ways to add sirens via Ajax apps: manually and automatically.

To add a siren manually:

1. Open the Ajax PRO app. Select the hub you want to add StreetSiren Fibra to.
2. Go to the Devices tab and select Add Device.
3. Assign a name to the device.
4. Scan or type in the QR code manually. The QR code is located on the back of the enclosure under the SmartBracket mounting panel and on the packaging.
5. Select a virtual room and a security group (if the Group mode is enabled).
6. Press Add.

To add the siren automatically:

1. Open the Ajax PRO app. Select the hub you want to add StreetSiren Fibra to.
2. Go to the Devices tab and select Add Device.
3. Select Add All Fibra Devices. The hub will scan all Fibra lines. After scanning, the Devices tab will show all devices physically connected to the hub that have not yet been added to the system. The order of the devices will depend on which line of the hub they are connected to.
4. In the list of available devices to add, select the device you need. The LED indicator of this device will start flashing. This way, you’ll know exactly which device you’re adding, how to name it correctly, and which room and group it should be assigned to.
5. To add a device, specify a name, room, and security group if the group mode is enabled. Press Save. If the device is added to the hub successfully, it disappears from the list of devices available for adding and appears in the Devices tab in the app.

Device status updating depends on the Fibra settings; the default value is 36 seconds.

If the connection fails, check if the wired connection is valid and try again. If the hub already has the maximum number of devices added (for Hub Hybrid, the default value is 100), you will get an error notification when you add one.

Please note that only 10 sirens or keypads with a built-in siren can be connected to one hub.

StreetSiren Fibra works with one hub only. After connecting to a new hub, the siren stops exchanging commands with the old one. Once added to a new hub, StreetSiren Fibra is not removed from the list of devices of the old hub. This must be done manually in Ajax apps.

Device Self-test

The Ajax system provides several tests for the correct choice of the device installation place. The test does not start straight away but not later than over a single “hub — device” ping period (36 seconds under default settings of the hub). You can change the ping period of devices in the Fibra menu of the hub settings.

Tests available for StreetSiren Fibra:

• Fibra Signal Strength Test. The test allows you to check a signal strength and stability at the installation site.
• Volume Test. Allows you to check the current siren volume level and select the optimal volume level for the protected object.
