Operating Principle
The siren performs four primary functions:
- Informs about alarms: Responds to system alarms and tamper triggers with sound and LED backlight to deter intruders and attract attention.
- Indicates security status: Provides visual notification of the system's armed status. It also alerts users to entry/leaving delays with sound and light signals.
- Notifies of opening (Chime): When the system is disarmed, it signals the activation of opening detectors, useful in retail environments to alert staff to customer entry.
- Notifies of triggering until disarmed: After an audible alert, the LED indicator flashes, allowing users and security personnel to identify triggered sirens.
Alarm Volume and Duration
Upon activation, the siren sounds for 3 seconds to 3 minutes, with a volume ranging from 85 to 107 dB. Users can configure alarm duration and volume, as well as specify which devices trigger the siren, through the Ajax apps.
Protection Against Sabotage
The Superior StreetSiren Plus Fibra is equipped with tamper buttons that trigger an alarm if the main power is lost or if the siren enclosure is opened/broken, or if an attempt is made to remove it from the SmartBracket. Sabotage events provide detailed notifications including hub name, incident time, siren name, alarm type, and assigned virtual room.
The pre-installed battery ensures the siren can indicate and notify of alarms and events during power outages or Fibra line disruptions.
Fibra Data Transfer Protocol
The siren utilizes Fibra technology for transmitting alarms and events, offering fast and reliable two-way communication. This wired protocol supports bus connection for instant delivery of alarms and events, even with up to 100 devices connected. Fibra employs block encryption with a dynamic key to prevent sabotage and spoofing, with regular device polling by the hub to monitor communication and status.
Sending Events to the Monitoring Station
Ajax systems can transmit alarms to the PRO Desktop monitoring app and central monitoring stations (CMS) using protocols such as SurGard (Contact ID), SIA (DC-09), and ADEMCO 685. The Superior StreetSiren Plus Fibra can transmit the following events:
- Lid open/closed status.
- Mounting panel locked/unlocked status.
- Alarms related to main power loss/recovery.
- Connection loss/recovery between the siren and the hub.
- Siren turning off/on.
- Battery discharging/charging.
- Battery disconnecting/connecting.
Addressability allows for detailed event transmission to PRO Desktop and CMS, including device type, name, and location. The specific parameters transmitted may vary based on the CMS and communication protocol.
Note: Device ID, loop (zone) number, and line number can be found in the device's states.
Selecting the Installation Site
When selecting an installation site for the Superior StreetSiren Plus Fibra, consider the following factors:
- Fibra signal strength.
- Required cable length for connection.
- Audibility of the siren's sound signal.
- Visibility of the siren's LED indication.
The siren is designed to withstand heat, cold, and temperature fluctuations, and is protected from rain and snow with an IP54 protection class. It can be installed on building facades without a canopy.
The recommended installation height is 2.5 meters or more to deter intruders. If this height is not feasible, the siren can be installed lower.
Follow placement recommendations for designing an Ajax system. The system design and installation should be performed by professionals. A list of authorized Ajax Systems partners is available here.
Do Not Install the Siren
- Near glass break detectors, as the sound may trigger false alarms.
- In locations where the siren's audio signal can be jammed.
- In places where the LED indication will not be visible.
- In areas with low or unstable Fibra signal strength.
Fibra Signal Strength
Fibra signal strength is determined by the ratio of undelivered or corrupted data packages to expected packages over a period. The Ajax app's Devices tab displays signal strength using icons:
- Three bars: Excellent signal strength.
- Two bars: Good signal strength.
- One bar: Low signal strength; stable operation not guaranteed.
- Crossed out icon: No signal; stable operation not guaranteed.
Factors affecting signal strength include:
- Number of devices on a Fibra line.
- Cable length and type.
- Correctness of wire connections to terminals.
Designing
Proper system design is crucial for correct installation and configuration. Consider the number and types of devices, their location and installation height, Fibra wire line lengths, and cable types. Tips for designing wired Fibra systems are available in this article.
Topologies
Ajax systems support three topologies: Beam (Radial wiring), Tree, and Ring.
Beam connection method
Occupies one line output of the hub. In case of a line break, only the connected segment functions; devices after the break lose connection.
Ring connection method
Occupies two line outputs of the hub. If the ring breaks, it reconfigures into two lines, maintaining normal operation. Users and security companies are notified of breaks.
Beam (Radial wiring) vs. Ring Topology:
Feature | Beam (Radial wiring) | Ring |
---|---|---|
Hub Line Output | One | Two |
Lines per Hub | Up to 8 | Up to 4 rings |
Communication Range | Up to 2,000 m | Up to 500 m |
Termination Resistor | Required at the end of the line | Not required |
Both topologies can be used on the same hub. For example, a hub can support two Ring connections and four Beam topology connections.
Various devices, including opening detectors, motion detectors with photo verification, sirens, and keypads, can be connected to a single Fibra line.
For Beam (Radial wiring) topology, a 120 Ohm terminating resistor must be installed at the end of the line, connected to the signal terminals of the last device.
Diagram showing Hub Hybrid connected to a Fibra device via a terminating resistor.
Line branching and Tree topology require Superior LineSplit Fibra.
Cable Length and Type
The maximum communication range for Beam (Radial wiring) is 2,000 m, and for Ring topology, it is 500 m.
Recommended cable types:
- U/UTP cat.5 4×2×0.51 mm (24 AWG) cable, copper conductor.
- 4×0.22 mm² signal cable, copper conductor.
Using different cable types may affect the communication range. Only tested cable types are recommended.
Verification Using a Calculator
Ajax has developed a Fibra power supply calculator to ensure correct project calculation and system functionality. The calculator assists in verifying communication quality and cable length for wired Fibra devices based on the system design.

Preparing for Installation
Cable Arrangement
When laying cables, adhere to local electrical and fire safety regulations. Routing cables inside walls, floors, and ceilings provides invisibility, protection from intruders, and durability against external factors.
If internal routing is not possible, protect cables with conduits or corrugated pipes, ensuring they are hidden and free from sagging, tangling, or twisting.
Avoid routing cables near sources of electromagnetic interference such as motors, generators, transformers, and power lines. Use twisted-pair cable in such areas.
Cable Routing
Consider general electrical installation requirements, installation height, fastening methods, and cable insertion into the enclosure when routing cables.
Refer to the 'Selecting the installation site' section before installation. Deviations from the system project or installation rules may lead to incorrect operation and loss of connection.
Inspect cables for bends and damage before routing; replace damaged cables.
Signal cables should be laid at least 50 cm from power cables when parallel, and at a 90° angle when intersecting.
Preparing Cables for Connection
Strip the cable using a special insulation stripper. Tin or crimp the wire ends with a sleeve for reliable connection and oxidation protection. Recommended cable lug sizes are 0.75 to 1 mm² (18 to 17 AWG).
