The Ajax Superior StreetSiren Plus Fibra in black is a wired outdoor acoustic and visual notification siren engineered for building facades and high-security perimeter wall mounting. Designed to deter intruders and alert neighbours instantly, it features a powerful piezoelectric sounder with configurable volume levels from 85 to 113 dB (at 1 meter distance) and customizable alarm durations from 3 seconds to 3 minutes. Its rugged IP54 weather-rated enclosure ensures reliable operation in rain, snow, and extreme temperatures from −25 °C to +50 °C.
In addition to acoustic alerts, the StreetSiren Plus Fibra incorporates a bright peripheral LED frame that flashes vividly during alarms while providing visual feedback for system arming states and entry/exit delays. Comprehensive physical protection is guaranteed by dual anti-tamper mechanisms: a physical tamper button for case opening and an internal accelerometer that triggers an alarm if the siren is moved, tilted, or torn from the mounting wall. It fully complies with top security standards, holding EN 50131-4 Grade 3, NFA2P, and PD 6662:2017 certifications.
#### Encrypted Long-Range Communication over Fibra Bus
Signal transmission and device power operate over the proprietary Fibra encrypted bus protocol, enabling extended line lengths up to 2,000 meters with optimized power consumption.
