The Ajax HomeSiren Jeweller is a compact wireless indoor siren designed to provide clear audible alerts inside homes, offices, retail spaces, and other protected premises. It forms part of the Ajax security system and helps notify occupants when an alarm is triggered.
HomeSiren connects wirelessly to an Ajax hub using Jeweller radio technology, allowing fast, secure, two-way communication between the siren and the alarm system. The siren can be configured through the Ajax app, making it easy to adjust alarm volume, alarm duration, indication settings, and device status.
The built-in LED can indicate system status, while an external LED indicator can also be connected if required. This is useful for installations where a separate visual status indicator is needed near an entrance, passage, reception area, or other visible location.
Designed for indoor use, the HomeSiren is battery-powered and can operate for up to 5 years from its pre-installed batteries. It includes tamper protection, communication loss detection, and quick SmartBracket mounting for a neat and professional installation.
