Exact Ajax 117727.268.WH1 White Variant

This listing is specifically for the Ajax Superior StreetSiren Plus Fibra 117727.268.WH1 in White.

The product identity should remain consistent throughout the EKM product name, description, specifications, FAQs, Merchant Center data, image alt text and structured product information.

This model must not be confused with the black Superior StreetSiren Plus Fibra, the wireless Superior StreetSiren Plus Jeweller, standard Ajax StreetSiren models or StreetSiren DoubleDeck products. Superior StreetSiren Plus Fibra is a wired Fibra device designed for compatible Ajax Hub Hybrid systems.

EN 50131 Grade 3 Professional Security

Superior StreetSiren Plus Fibra is designed for professional security installations and is specified to EN 50131 Grade 3.

Grade 3 equipment is intended for security systems where there is a significant risk of intrusion and where attackers may be expected to have knowledge of alarm systems and access to specialist equipment.

Ajax also specifies compliance with PD 6662:2017 for this product, making it particularly relevant to professionally designed UK intrusion-alarm systems where compatible devices are configured according to the appropriate system requirements.

Compliance of an individual device does not automatically mean that every installation achieves a particular security grade. The complete alarm system must be designed, installed and configured using compatible equipment and appropriate installation practices.

Powerful Adjustable 85–107dB Alarm

The built-in speaker provides an adjustable alarm sound level from 85dB to 107dB measured at a distance of 1m.

This allows installers or authorised Ajax users to select a suitable alarm volume for the protected premises rather than operating at one fixed sound level.

The alarm duration can also be configured from approximately 3 seconds to 3 minutes through compatible Ajax applications.

• Minimum configurable alarm volume: approximately 85dB at 1m
• Maximum alarm volume: approximately 107dB at 1m
• Configurable alarm duration: 3 seconds to 3 minutes
• Speaker frequency: approximately 1,400–1,600Hz

The siren can therefore provide a strong audible deterrent while allowing the installation to be configured according to the requirements of the building and alarm system.

Bright LED Frame for Visual Alarm Indication

Superior StreetSiren Plus Fibra incorporates a highly visible LED frame in addition to its acoustic alarm.

The visual indication can be used for multiple security-system functions including alarm indication, security-mode indication, entry and exit delays and after-alarm indication.

This visual feedback can make it easier for users, installers and responding personnel to understand the current alarm state without relying entirely on acoustic signals.

After-Alarm LED Indication

The siren can provide an after-alarm LED indication to show that an alarm has previously occurred in the system.

This can be useful when users or security personnel approach the protected premises after an event because the siren can provide visible confirmation that an alarm has taken place.

The exact behaviour depends on the Ajax system configuration and firmware.

Entry and Exit Delay Indication

Superior StreetSiren Plus Fibra can provide acoustic and LED indication during configured entry and exit delays.

This helps users understand when the security system is counting down before arming or before generating an alarm after entry.

The required indication behaviour can be configured through compatible Ajax applications by authorised users or installers.

Chime Function for Door Opening Notifications

The siren supports the Ajax Chime function when used with compatible opening detectors.

When enabled, Superior StreetSiren Plus Fibra can produce a short audible notification when an opening detector is triggered while the security system is disarmed.

This can be useful for shops, offices, reception areas and other premises where staff want an audible indication when a monitored entrance or door is opened.

Encrypted Fibra Wired Communication

Superior StreetSiren Plus Fibra communicates with a compatible Ajax hub using Ajax Fibra wired technology.

Fibra is designed for secure two-way communication between professional Ajax wired devices and the hub. Device data is encrypted during communication, helping protect system information against unauthorised interception or substitution.

Because this is a Fibra product, it is fundamentally different from Ajax Jeweller wireless sirens. It requires a physical wired connection to a compatible Fibra line.

Up to 2,000m Wired Communication Range

Ajax specifies a Fibra wired communication range of up to 2,000m when Superior StreetSiren Plus Fibra is connected using suitable U/UTP Cat.5 copper cable under the specified conditions.

This long wired range can make Fibra suitable for larger residential properties, commercial buildings, warehouses, offices, industrial sites and other installations where alarm devices may be positioned significant distances from the main hub.

The achievable cable length in a real installation depends on cable type, topology, connected devices, power requirements and overall system design.

Compatible with Ajax Hub Hybrid

Ajax specifies compatibility with:

• Ajax Hub Hybrid (2G)
• Ajax Hub Hybrid (4G)

This siren should not be treated as a standalone device and should not be advertised as compatible with every Ajax hub.

Because it uses Fibra wired technology, the system requires a compatible Ajax controller with Fibra support.

Built-In Rechargeable Backup Battery

Superior StreetSiren Plus Fibra contains a pre-installed rechargeable backup battery. The battery is automatically charged from the Fibra line during normal operation.

If the Fibra line is damaged or primary line power becomes unavailable, the built-in battery can continue powering alarm and event indication for a limited period.

Ajax technical documentation specifies an LTO 18650 rechargeable battery rated at 3,000mAh and 2.4V. The published technical sheet specifies up to approximately 30 minutes of alarm signalling after loss of primary power.

The backup battery is integrated as resilience for the alarm system and should not be confused with normal battery-only operation. Superior StreetSiren Plus Fibra is fundamentally a wired Fibra device.

24V Power from the Fibra Line

Normal operating power is supplied through the Ajax Fibra line at 24V DC.

This means the same wired infrastructure provides both communication and power for the siren within the compatible Ajax system.

Correct cable selection and system power calculations remain essential, particularly when multiple devices are installed on the same Fibra infrastructure.

Protection Against Sabotage

Superior StreetSiren Plus Fibra incorporates protection designed to detect attempts to interfere with the device or remove it from its mounting position.

The SmartBracket installation system and enclosure tamper detection allow the Ajax system to generate tamper events if the device is opened or improperly removed.

Fibra system architecture also provides protection against communication faults such as line breakage and short circuits when the overall system is correctly installed and configured.

SmartBracket Professional Installation

The siren is supplied with the Ajax SmartBracket mounting panel.

SmartBracket allows the device to be mounted without unnecessarily dismantling the main enclosure and provides suitable fixing and tamper points for professional installation.

Ajax also incorporates a bubble level into the mounting arrangement to assist with accurate positioning during installation.

Indoor and Outdoor Installation

Superior StreetSiren Plus Fibra is designed for both indoor and outdoor installation.

The enclosure carries an IP54 protection rating and is designed to withstand normal outdoor exposure including rain, snow and changing environmental conditions when installed according to Ajax instructions.

Ajax specifies an operating temperature range from -25°C to +60°C and operating humidity up to 95%.

• Protection rating: IP54
• Operating temperature: -25°C to +60°C
• Operating humidity: up to 95%

Recommended Installation Height

Ajax recommends positioning Superior StreetSiren Plus Fibra approximately 2.5m or higher where practical.

A higher mounting position can make the device more difficult for an intruder to reach while improving visibility of the LED indication and distribution of the audible alarm.

The siren can be mounted lower where site conditions require it, but installers should consider audibility, LED visibility, Fibra communication and sabotage resistance when selecting the final position.
