Promote security. Advertise services.
StreetSiren DoubleDeck Jeweller combines robust security with promotional opportunities. Not only does it alert users and security companies to alarms and system events, but it also features Brandplate — a customizable front panel for displaying logos, contact details, or other branding. This transforms the siren into a visible advertisement for security or installation companies, catching the attention of neighbors and passersby. With sound levels up to 113 dB, LED indication, the Chime feature, and after-alarm indication, the siren ensures that no event goes unnoticed. Suitable for both indoor and outdoor use, StreetSiren DoubleDeck Jeweller relies on secure radio communication via the Jeweller radio protocol and can be easily configured using Ajax apps.

Security that fits every setting
StreetSiren DoubleDeck Jeweller is designed to be used in diverse environments, proving equally effective in quiet suburban areas and bustling public facilities. The piezoelectric alarm indicator can generate sound ranging from 85 to 113 dB in volume for a configurable duration of 3 seconds to 3 minutes. Meanwhile, the siren can also operate silently, using only LED signals to respond to alarms. Ajax apps allow installers to choose which detectors activate the siren, helping to prevent unnecessary alerts.
Wire-free flexibility and reliable performance
The StreetSiren DoubleDeck Jeweller offers wireless flexibility and reliable performance. It runs on pre-installed CR123A batteries, which last about five years and can be monitored via Ajax apps for low-battery warnings. Its unique Jeweller technology ensures secure communication with encryption and device authentication to prevent sabotage. The device includes an automatic self-diagnosis feature to report status and malfunctions. With a tamper alarm, protective enclosure, and an accelerometer, it ensures high security. Installation is easy with a SmartBracket panel, and devices can be managed remotely.

Overview:
StreetSiren DoubleDeck is a wireless outdoor siren with mount for the branded faceplate. Equipped with a LED frame and piezoelectric alarm indicator producing sound volume up to 113 dB, StreetSiren can operate up to 5 years from pre-installed batteries. It can also be powered from an external 12 V power supply.
StreetSiren DoubleDeck communicates with the hub via the secured Jeweller radio protocol. The communication range is up to 1,500 meters provided there are no obstacles.
The siren is set up via Ajax apps for iOS, Android, macOS, and Windows. The system notifies users of all events with push notifications, SMS, and calls (if activated).
