Instant Emergency Alerts Without the False Alarms Introducing the AJAX DoubleButton, a wireless hold-up device designed for immediate threat notification with an advanced layer of protection against accidental activation. In a critical situation, every second counts. The DoubleButton ensures that you can send a confirmed alarm to a security agency or notify family members with a single, decisive action.
Its innovative design requires two buttons to be pressed simultaneously, which are separated by a plastic divider. This thoughtful engineering eliminates false alarms from accidental presses, making it safe to carry in a pocket, purse, or wear on a lanyard. Uncompromising Reliability with Jeweller Technology The DoubleButton operates on AJAX's proprietary Jeweller radio technology, ensuring a secure and reliable connection to the hub up to 1,300 meters away in open space.
This two-way communication protocol features block encryption with a dynamic key and frequency hopping to prevent interception and jamming. All transmitted data is protected, and in case of signal interference, the system instantly switches to a clear frequency, notifying you and your security company.
A clear LED light provides visual confirmation that your alarm has been successfully delivered. Built for Durability and Longevity Designed to be hassle-free, the DoubleButton boasts a pre-installed battery that lasts up to 5 years, eliminating the need for frequent maintenance. Its robust enclosure is rated IP55, making it resistant to dust, splashes, and extreme temperatures ranging from -10C to +40C.
This ensures reliable operation when you need it most. Whether kept portable or fixed to a surface using the AJAX Holder (sold separately), the DoubleButton is a dependable addition to your security system.
