Smart wired siren on high alert
Superior HomeSiren Fibra is a wired indoor siren that responds to Ajax system alarms in less than a second. This device emits a sound of up to 105 dB, which is loud enough to deter intruders and alert an entire facility, even as large as a factory. The siren can also indicate exit/entry delays and inform users of alarms from any detector in the system. For example, it is possible to set up a sound signal when the door1 is opened. Superior HomeSiren Fibra users with admin rights can remotely configure alarm types, volume levels, and other siren settings via Ajax apps for PROs.

Informs of any alert
The siren emits an alarm signal in the event of a threat, such as a fire, water leakage, or intrusion. The loud sound will also help scare away an intruder. An installation engineer configures alarm types and the siren volume in Ajax PRO apps.

Indicates delays
Superior HomeSiren Fibra can be configured to signal the delay when entering or leaving. If the feature is enabled, the built-in or external LED indicator and sound remind a user that the site needs to be disarmed.

Displays the security mode
The siren can inform about a security mode change with sound and light indication. The LED indicator can also be always on to keep the siren’s state secret from outsiders.

Notifies of doors being opened
Superior HomeSiren Fibra provides the Chime feature. It allows the siren to play a specific sound when opening detectors are triggered while the system is disarmed. The feature is ideal for stores, as it instantly alerts employees when new visitors enter.

Provides after-alarm indication
When the after-alarm indication is enabled, the LED indicator signals confirmed and unconfirmed alarms and tamper alarms until the system is disarmed.

Precise sound settings
Superior HomeSiren Fibra is flexible in its settings. The buzzer can be configured to emit sound5 from 81 to 105 dB for an adjustable period: from 3 seconds to 3 minutes. Alternatively, the siren can operate silently, using only the LED indicator to signal alerts. In Ajax apps, installers can configure which detectors activate the siren, avoiding unnecessary alerts.

Fibra
Unique wired technology
Fibra is Ajax’s proprietary technology for secure two-way communication between devices and a hub or module that extends the Fibra line. Fibra features encryption and device authentication to prevent sabotage, spoofing, and data theft. The Fibra line supports all types of devices, including sirens, keypads, and detectors with photo verification.

Communication range of up to 6,550 ft
One Fibra line for different device types
Photo delivery via Fibra line without interference
Protection against sabotage and spoofing
Energy efficiency as a priority
Fibra communication is based on the TDMA principle, according to which each device has a short time frame for exchanging data with the hub. The device’s communication module remains inactive the rest of the time. This significantly reduces power consumption and helps minimize interference even when multiple devices communicate simultaneously.
TDMA principle
Power consumption of up to 1.8 W

System supervision
All Ajax devices perform automatic self-diagnosis and report their states to the hub. Essential parameters, such as tamper, communication, and power supply statuses, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for monitoring companies and users. In case of any malfunction or connection failure, an installation engineer is informed immediately to provide necessary services.
Automatic device self-diagnosis with status report
Regular polling to display the current device state in apps

Protection against short circuits and sabotage
Introducing Superior LineProtect Fibra, a module to protect an Ajax hub and wired devices from sabotage when an intruder causes short circuits, applies 110/230 V~, or uses stun guns.
PRO is king
The myth about wired systems being difficult to install is busted. Ajax minimized an expensive, long, and dusty experience for PROs by developing an ultimate set of tools to make the process easy and flexible, from project design to client support and system maintenance. There is no need to disassemble the device for installation. Intuitive Ajax apps help quickly make the siren a part of the system, and each device can be reconfigured remotely at any moment. No programming required — everything is available out of the box.
Fibra power supply calculator
The online tool provides security engineers with detailed data on devices’ power consumption, enabling easy pre-installation assessment of the wired system project. It helps design the project in real time, highlights problem spots, and offers solutions. Upon completion, results can be downloaded as a PDF file.
The SmartBracket panel allows installers to mount the siren on the wall quickly and effortlessly. The installation kit includes all the necessary fasteners.

The device pairs with the hub automatically via Fibra line scanning. This tool is available in desktop or mobile PRO apps. An installer only needs to name the device and assign it to the room and security group. The device can also be added by scanning the QR code or entering its ID manually.

From 3 seconds to 3 minutes.
When the U/UTP cat.5 4×2×0.51 mm (24 AWG) cable is used. Other cable types may have different values. Please use the Fibra power supply calculator to check the wired system project before installing the device.
This means that up to 10 sirens, including keypads with built-in buzzers, can be added to the system.
The volume level was measured 1 meter away from the siren.

Siren in burglar alarm
A burglar alarm siren is a device designed to protect premises from break-ins and thefts. After the security system sensor is triggered, a siren is activated, which, by sound or light, draws the attention of neighbors to the guarded object and scares off intruders from the scene.How a home alarm siren works
After the alarm control panel (central panel) sends an alarm signal received from the sensors to the siren, the light, sound or light and sound indication of the event turns on. The sound signal can be of different tones, with a power of up to 110 dB. The light alert often looks like a flashing beacon or flashing light. Some sirens are also equipped with tampers, as are many other security devices. The tamper is a switch that works and activates the siren if an intruder tries to remove the siren from its mounting or damage its case.Types of sirens
In security systems, sirens of the following types are distinguished:- Wired sirens
- Wireless sirens
- Standalone sirens
Superior HomeSiren Fibra wired siren for indoor installation
Superior HomeSiren Fibra is a wired indoor siren. The detector notifies of the operation of the system's sensors with a sound volume of up to 105 dB. The home siren supports external LED connection. The Superior HomeSiren Fibra indoor siren works only as part of the Ajax security system. The siren communicates with the alarm control panel (central panel) via the secure Fibra protocol. The communication range is up to 2 kilometers if connected via a U/UTP cat.5 twisted-pair cable. The siren works with the Superior Hub Hybrid alarm central panel. Connection to other control panels, radio signal repeaters, integration modules is not provided.Benefits of using the Superior HomeSiren Fibra indoor siren in a security system
- The Ajax Superior HomeSiren Fibra alarm siren responds to security and tamper alarm in less than a second. The sound of a siren for an indoor installation is enough to attract the attention of neighbors and scare off intruders.
- The duration of the sound and the volume level of the siren can be adjusted in the application: in case of an alarm, the buzzer can be activated from 3 to 180 seconds with a sound volume of 81-105 dB. In the Ajax app, you can choose which security sensors will activate the siren.
- The LED indication of the siren informs that the object is under protection, and by sound informs about entry or exit delays. These functions are used when controlling the security system using keypads and key fobs: the siren reminds you to disarm the alarm at the entrance to the premises.
- The wired siren Superior HomeSiren Fibra, which worked, is not easy to dismantle or turn off: the body of the device is strong, and the buzzer is protected. For additional protection of the siren from opening the case, the device is equipped with a tamper button.
- To transmit events and alarms, the siren uses a two-way wired Fibra data transfer protocol. The technology provides fast and reliable communication between the control panel and devices connected to the system.
