Wireless Grade 3 Outdoor Siren with LED Frame, IK08 Protection and Jamming Detection Ajax Superior StreetSiren Plus G3 Jeweller Black
The Ajax Superior StreetSiren Plus G3 Jeweller in black sets a new benchmark for professional outdoor alarm notification. It is the world's first wireless outdoor siren to obtain prestigious EN 50131 Grade 3 certification, designed specifically to safeguard critical infrastructure, commercial premises, and high-risk residential properties requiring ultimate resistance against sabotage.
Featuring a powerful acoustic sounder adjustable between 85 dB and 107 dB at 1 meter (with toggling between Regular and NFA2P sound pattern modes) alongside a bright LED frame, the StreetSiren Plus G3 executes five vital operational missions: sounding loud intrusion alerts, confirming arming/disarming status, signaling entry/exit delays, alerting on door openings (Chime), and displaying continuous after-alarm visual alerts (blinking LED notifying owners if an alarm occurred in their absence).
Engineered to endure extreme outdoor weather conditions without requiring protective canopies, its durable enclosure carries an IP54 rating (resistant to dust, rain, and snow) and IK08 impact protection against vandalism and physical blows, operating seamlessly between −25 °C and +60 °C with humidity up to 95%.
#### Grade 3 Sabotage Resistance & Flexible Power Options
Powered by the Superior Jeweller protocol, the siren features direct onboard jamming detection with dynamic frequency hopping. Sabotage defenses are reinforced by dual tamper switches that trigger instant notifications if the enclosure is opened or unmounted from the SmartBracket mounting panel.
The device offers maximum power flexibility: it operates completely wirelessly on its internal set of 8 pre-installed CR123A lithium batteries (delivering up to 10 years standby life or 4.2 years under regular use) or can be connected to an external 12 V⎓ (1.5 A) power supply. When connected to 12 V⎓, the LED frame provides full-frame backlighting while internal batteries act as emergency power backup.
