Operating principle

ajax streetsiren fibra

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

The siren performs two tasks:

  1. Informs about alarms. The siren responds to tamper triggering and security system alarms, including a buzzer and LED backlight, in less than a second, which scares off intruders and attracts the attention of neighbours.
  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 helpful if you control the security system using key fobs or keypads. In this case, the siren can remind you to disarm the system when you enter the object.

Alarm volume and duration

When alarmed, the siren sounds for 3 to 180 seconds, producing 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. We discuss this feature in more detail in the Settings section.

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

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), 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. Temporarily turning the siren off/on.

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 StreetSiren Fibra, consider 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.

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.

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.

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 security system devices, it is important to properly design the security system project. The design must consider 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 security systems support two topologies: Beam (Radial wiring) and Ring.

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

Beam (Radial wiring) connection method 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 streetsiren fibra

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

ajax streetsiren 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 device connection topologies can be used on the same hub. For example, you can use two Ring connections and four Beam (Radial wiring) 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.

ajax streetsiren fibra

For the Beam (Radial wiring) 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 streetsiren fibra

Cable length and type

The maximum communication range for wired connection using the Beam (Radial wiring) 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 that such a system will work in real practice, we have developed a communication range calculator of Fibra lines (in progress). 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. 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 calculator (in progress).

You can connect up to 100 devices to Hub Hybrid by default.

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 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 cables for a security system, consider 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 location section of this manual. Avoid deviations from the security system project design. 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.

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 specified by the manufacturer in the cable specifications. Otherwise, you risk damaging or breaking the conductor.

The devices are connected to the Fibra 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 only. 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 special 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 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 tips. This will ensure a reliable connection. Follow safety procedures and regulations for electrical installation work.

Connecting StreetSiren 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 board with terminals for connection of StreetSiren Fibra from the holders on the mounting panel by pulling them aside.

Clean the siren enclosure from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth suitable for equipment care.

Do not use substances that contain alcohol, acetone, gasoline, or other active solvents to clean the siren.
