Security that fits every setting

Superior StreetSiren Plus Jeweller adapts seamlessly to both quiet residential areas and noisy industrial environments. The siren offers two sound patterns, namely Regular and NFA2P-compliant, and adjustable volume ranging from 85 to 107 dB4. The alarm duration can be set3 from 3 seconds to 3 minutes. Alternatively, the siren can operate silently, using only the LED frame to signal alerts. In Ajax apps, installers can configure which detectors activate the siren, avoiding unnecessary alerts.

• Selectable sound patterns: Regular and NFA2P-compliant
• Alarm volume: up to 107 dB4
• Alarm duration: up to 3 minutes3

Weatherproof

Superior StreetSiren Plus Jeweller is designed to withstand various weather conditions. Thanks to the IP54-rated enclosure, the siren resists dust, rain, and snow and can be installed on exterior walls without a canopy.

Outstanding autonomy

Superior StreetSiren Plus Jeweller features a powerful set of eight batteries, which provides up to 10 years of autonomous operation and up to 13 hours of operation in alarm mode. In addition to real-time testing during battery production, Ajax Systems inspects every unit to ensure the accuracy of the batteries’ characteristics. The batteries provide stable performance at temperatures from –25 °C to +60 °C.

• Up to 10 years of autonomous operation
• Up to 13 hours of operation in alarm mode
• Minimal impact of threshold temperatures on battery life
• Battery quality proven by regular tests

Unique wireless technology

Jeweller is Ajax’s proprietary radio protocol for secure two-way communication. It provides block encryption and device authentication during each communication session with an Ajax hub or radio signal range extender. Jeweller prevents sabotage, spoofing, and data theft.

System supervision

All Ajax devices perform automatic self-diagnosis and report their states to the hub. Essential parameters, including tamper, communication, power supply, and sensor statuses, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for CMSs, security companies, and users. In case of any malfunction or communication failure, an engineer is informed immediately to provide necessary services.

Sabotage resistance

Tamper alarm
The device is equipped with two tampers. The first tamper triggers when SmartBracket is unlocked. The second tamper triggers if an attempt to detach the siren from the surface or SmartBracket is detected.

Data encryption
All data the system stores and transmits is protected by block encryption featuring a dynamic key. This encryption deters intentional sabotage attempts on the detector.

Data-rich notifications
An Ajax system instantly delivers informative notifications of alarms and events. Security companies and users receive precise details about the incident, including the triggered device, along with the time and location.

Device authentication against spoofing
The hub checks the siren’s unique parameters for authentication during each communication session. If any parameter fails the check, the hub ignores device commands.

Regular polling
The siren regularly exchanges data with the hub. The system controls each device state and reports if there is a malfunction or connection loss.

Connection loss detection
With minimal polling interval settings (3 data packages in 12 seconds), it takes 36 seconds to identify connection loss and notify the security company and users of the incident.

Protected enclosure
The siren enclosure is designed to minimize the impact of vandals and the environment on its operation. A dense enclosure with special sealing bands and sealant provides weather protection and is certified with an IP54 rating. Durable plastic and metal grating ensure additional protection. Secure mounting prevents the siren from being detached from the wall.

Jamming detection
Superior StreetSiren Plus Jeweller features a radio interference detection algorithm. When a potential jamming attempt occurs, the algorithm detects a sudden increase or decrease in the noise level. It takes into account not only the amplitude of the noise but also the duration over time.

Effortless installation and setup

Superior StreetSiren Plus Jeweller is ready to operate out of the box. Installers can use the SmartBracket panel to mount the siren, eliminating the need to disassemble the enclosure. Ajax apps help quickly make the device a part of the system: simply pair the siren with the hub by scanning the QR code. It can always be reconfigured remotely without the need for on-site visits.
