The Ajax Superior StreetSiren DoubleDeck Jeweller in black is a powerful outdoor siren designed to deter intruders and instantly alert the surroundings. Certified to EN 50131 Grade 2 standards, it combines a loud acoustic buzzer with a bright red LED frame for visual notification of alarms and entry/exit delays.
The highlight of the DoubleDeck model is its capacity for commercial branding: the siren is engineered to clip on the Brandplate front panel, allowing security companies and installers to print their logo and contact details. Please note: The Brandplate front cover is NOT included with the siren and must be purchased separately.
The siren features adjustable volume levels from 85 to 113 dB and configurable alarm durations from 3 to 180 seconds. Its rugged IP54-rated enclosure protects internal components against dust and water jets, operating smoothly between −25 °C and +60 °C.
#### Anti-Sabotage Protection & Flexible Power
StreetSiren DoubleDeck is equipped with complete sabotage protection: an onboard accelerometer detects any attempt to detach or unmount the siren from the wall, complemented by an enclosure opening tamper switch. Alarms are transmitted in 0.15 seconds over the encrypted Jeweller radio protocol (up to 1,500m range).
Powered by 4 pre-installed CR123A batteries (providing up to 5 years of battery life), it can also be connected to an external 12 V⎓ power supply (with batteries serving as backup).
