HomeSiren Jeweller

Wireless siren with an LED connector.

Loud and reliable

HomeSiren Jeweller is a smart indoor device that does more than alerting alarms. It can also serve as a security status indicator, notify ​of​ door openings​, and display delays when entering or leaving and after-alarm. The device operates autonomously on pre-installed batteries for up to 5 years and uses wireless Jeweller radio protocol to communicate with a hub or range extender at a distance1 of up to 2,000 m. HomeSiren Jeweller is protected at hardware and software levels and easy to control via Ajax apps.

One device. Five missions

• Informs about any alert
• Indicates the delays
• Displays a security mode
• Notifies of door opening
• Signals the after-alarms

Unique wireless technology

An Ajax system uses two-way secure radio communication based on the Jeweller proprietary protocol. It provides block cipher encryption and device authentication at each communication session with the hub to prevent sabotage, spoofing, or data theft.
