The Ajax Superior HomeSiren Jeweller in white is a wireless indoor siren designed to issue loud audible alerts during intrusions and scare away uninvited guests. Certified to EN 50131 Grade 2 standards, it features a high-intensity piezoelectric sounder generating up to 105 dB and an integrated LED frame for visual feedback.
As part of the professional Superior product line by Ajax Systems, it is optimized for commercial and high-end residential security installations. In addition to custom volume levels (81 dB to 105 dB), the siren features a dedicated connector for a third-party external LED, extending visual alarm status indication outside the mounting room.
HomeSiren Jeweller also supports the Chime function, emitting a pleasant tone when magnetic opening detectors are triggered while the system is disarmed.
#### Sabotage Protection & Battery Life
The device is built with anti-tamper hardware on the SmartBracket mounting panel, triggering an immediate alarm if unmounted or opened. A dedicated holding screw prevents rapid physical removal by intruders.
Two-way communication with the hub relies on the Jeweller radio protocol at distances of up to 2,000 meters in open space. It runs autonomously for up to 5 years on two pre-installed CR123A batteries.
