Enhanced security with additional detectors
DoorProtect Plus Jeweller has terminals for connecting any third-party wired NC detector that can be used to enhance the reliability of the system. An installer can integrate a detector operating on a different principle, such as a roller shutter motion detector. When connected to DoorProtect Plus Jeweller, a third-party detector promptly responds to alarms from other detectors and cable breakage.
Use a detector as a doorbell
The Chime feature transforms the combination of an Ajax opening detector and siren into a shopkeeper's bell. When the system is disarmed, the siren notifies about door openings with one of four available short sound signals. PRO users can adjust the volume and assign different signals for separate entrances, making it easy to recognize whether someone entered through the main or a back door.

Overview:
DoorProtect Plus Jeweller is a wireless opening, shock, and tilt detector. Supports connection of a third-party wired detector with a normally closed (NC) contact type. For indoor installation.
Nota:The detector is not compatible with ocBridge Plus and uartBridge integration modules.
DoorProtect Plus Jeweller operates as part of the Ajax system by connecting to the hub via the secure Jeweller radio protocol designed to transmit alarms and events. The hub communication range is up to 1,200 meters without obstacles.
Key Features:
Beyond opening detection
- Reed switch detects openinJ
- Built-in accelerometer detects shock, vibration, and tilV
- Detector features protection against chattering and an option to ignore single impacts, preventing false alarms
- Three sensitivity levels of the shock sensor are adjustable in Ajax apps
Additional features
- Terminals for connecting a third-party NC detectox
- Chime feature: Ajax sirens notify users about door openings with a special sounq
- Two magnets1 in the kit provide more installation options
