The Ajax Button in black is a versatile wireless device that serves as both a panic button and a smart home controller. Using the Jeweller two-way radio protocol, it maintains a reliable connection with the Hub at distances of up to 1300 meters. You can configure it to trigger various alarm types, including silent or audible alerts for dangerous situations, fire alarms, gas leaks, or general calls for assistance. Beyond security, it acts as a remote for your home automation, allowing you to operate lights, shutters, or gates through short or long presses configured in the app. Designed for durability and ease of use, this black device is dust and splash resistant. It is powered by a single CR2032 battery, which is pre-installed and can last up to 5 years. A small green LED indicator on the case provides visual confirmation of its status. To prevent accidental triggers, the button requires a deliberate press, and you can customize whether a single, double, or long press activates a specific scenario. Setting up the device is straightforward via QR code scanning through the Ajax application. For placement, it includes a holder bracket for surface mounting, though it is equally effective when carried as a keychain or on a lanyard. This makes it a practical choice for anyone needing a quick way to signal for help or manage their home environment from a distance.
