Description:
The HomeSiren Jeweller offers an adjustable sound volume from 80 to 98 dB, with alarm durations ranging from 3 seconds to 3 minutes. Its built-in LED and external LED connector display the armed or disarmed status, delays, and after-alarms. The siren connects wirelessly to the hub or range extender within a 2,000 m range and operates autonomously on pre-installed CR123A batteries for up to five years. It supports tamper detection, jamming alerts, and two-way encrypted communication to prevent sabotage or spoofing. Installation is simple using the SmartBracket panel, and device setup is completed through the Ajax app.
Features:
Advanced Protection for Smart Interiors
This device goes beyond simple noise generation by acting as a comprehensive status indicator for your property. It can be configured to signal entry and exit delays, reminding users to disarm the system and preventing false alarms. The integrated LED offers a visual confirmation of the current security mode, while an additional connector allows for an external LED to be mounted outside an office or apartment to show the armed status from a distance.
Functional Versatility and Chime Mode
- Audible alerts for fire, water leaks, or unauthorized entry help protect lives and property.
- The Chime feature is an ideal solution for retail environments, producing a distinct sound when doors open while the system is disarmed.
- Users can customize which specific detectors trigger the siren and for what duration.
- Visual after-alarm indications allow owners to see if a security breach occurred during their absence.
Reliability Through Jeweller Technology
Operating on the proprietary Jeweller radio protocol, the siren maintains a constant, encrypted connection with the Ajax hub. This technology ensures that any attempts at signal jamming or interference are detected immediately. The system uses block cipher encryption and device authentication during every session to prevent spoofing or unauthorized access. Even in complex environments with thick walls, the signal remains stable, and the range can be further extended using radio signal range extenders.
Optimized Energy Efficiency
- Pre-installed CR123A batteries provide up to 5 years of autonomous operation without maintenance.
- The Ajax app provides early low-battery warnings to ensure the system is always active.
- Intelligent power management adjusts the signal strength based on the distance to the hub to conserve energy.
Quick Mounting and Configuration
Setting up the siren is a straightforward process that requires no specialized tools or enclosure disassembly. The device is ready to work right out of the box with batteries already inside. By scanning a QR code through the mobile app, the siren pairs with the hub instantly. The included SmartBracket mounting panel allows for secure attachment to walls in just a few minutes, while all fine-tuning of volume and logic is handled remotely through the software interface.
