Visual indication
Sounder/VAD (Blue) Jeweller features a blue LED frame that flashes brightly during an alarm in a compliant temporal pattern. The device can be mounted on a wall or ceiling, giving installers more flexibility to achieve optimal visual coverage with fewer devices.
Effortless installation and maintenance
Sounder/VAD (Blue) Jeweller is designed for quick, hassle-free installation. Ready to use out of the box, it can be installed in minutes without disassembling the enclosure. Adding the device to the system and configuring it is just as simple: Ajax apps provide an intuitive interface to minimize the risk of human error during setup.
Adding the device to a system takes just a QR code scan. All setup, connection checks, and coverage tests are handled in Ajax PRO apps — no complex configuration or programming required.
The SmartBracket mounting panel with pre-marked fixing points eliminates the need to disassemble the enclosure. Installers can also fine-tune positioning by rotating the device up to 90 degrees. For added security, the complete set includes a lock to prevent unauthorized removal.
The device automatically tests the signal strength and alarm annunciation. Installers can initiate the test with a simple tap in the app, and the results appear in the log within seconds.
Unique wireless technology
When every second counts, there's no room for delays or a dropped connection. That's why Sounder/VAD (Blue) Jeweller uses the Jeweller two-way radio communication protocol — a proprietary Ajax technology that activates sounders and VADs in as little as three seconds after a fire alarm is triggered.
The device maintains a stable connection to the central unit over a distance of up to 1,700 m in open space — no external communicators required. For sites with obstacles, a range extender can double the coverage or use an Ethernet connection to create a separate radio network.

Efficient autonomy for years to come
Pre-installed batteries provide 5 years of autonomous device operation. Real-time battery state is always visible in Ajax apps. When the battery is low, Ajax apps send a warning notification. Replacing the batteries takes no tools or enclosure disassembly — just remove the battery cover.
