DoubleButton Jeweller
DoubleButton Jeweller is a wireless hold‑up device designed for intentional, high‑certainty alarm activation. Its dual‑button design prevents accidental presses, while optional confirmed alarm sequences ensure that only deliberate actions trigger a response. With long‑range encrypted communication, IP55 protection, and up to five years of battery life, it is suitable for both residential and commercial high‑risk environments.
Key Features
- Dual‑button activation to eliminate accidental presses
- Confirmed alarm support using configurable press sequences
- Always active — no wake‑up delay before transmission
- Jeweller two‑way encrypted communication with up to 1,300 m range
- AES‑based encryption and device authentication
- IP55 protection for indoor and sheltered outdoor use
- Up to 5 years battery life on a single CR2032 cell
- Portable or fixed installation using the optional Holder
How It Works
DoubleButton Jeweller communicates with an Ajax hub using the Jeweller radio protocol, ensuring fast and secure alarm delivery. To prevent false alarms, both buttons must be pressed simultaneously, and the plastic divider prevents accidental activation in pockets or bags. For high‑security environments, confirmed alarm sequences can be enabled, requiring a specific combination of short and long presses.
