Instant, Powerful, and Smart Indoor Alert
Deter intruders and alert everyone in the vicinity with the AJAX HomeSiren Jeweller, a powerful wireless indoor siren designed for the modern smart security system. Ready to work straight out of the box, this sleek black siren installs in minutes and provides an immediate and robust layer of audible security. When any detector in your Ajax system is triggered, the HomeSiren activates with a loud, adjustable alarm, ensuring that any threat is met with an unmistakable warning.
Customizable to Your Needs
Take full control of your alert system. Through the intuitive Ajax mobile app, you can easily adjust the siren's volume from 81 to 105 dB and set the alarm duration from 3 seconds up to 3 minutes. This flexibility allows you to tailor the siren's response to suit the size of your space and your specific security preferences. The device also features a built-in LED to indicate the system's armed or disarmed status and includes a connector for an optional external LED, which can be placed outside to visibly monitor your security status.
Uncompromising Wireless Reliability
The HomeSiren operates on AJAX's proprietary Jeweller radio technology, ensuring a secure and reliable connection to the hub up to 2,000 meters away in open space. This advanced two-way communication is encrypted and protected against jamming and forgery, providing a tamper-resistant link you can trust. The system constantly polls the device, with communication loss detected in as little as 36 seconds. With a remarkable battery life of up to 5 years from its pre-installed CR123A batteries, you can count on long-term, maintenance-free protection.
Advanced Features for Complete Peace of Mind
Beyond a simple alarm, the HomeSiren is a smart component of your security ecosystem. It features a 'Chime' function that can produce a special sound to notify you when opening detectors are triggered while the system is disarmed. A built-in tamper alarm will instantly notify you of any attempt to detach the siren from its mount or remove the enclosure. Easy to install with the SmartBracket mount and simple to connect to your hub via a QR code, the HomeSiren Jeweller is the essential indoor audible alert for your AJAX security system.
