Wireless reed-switch opening detector

Standards and certifications
DoorProtect Jeweller · DP.Y.J. Manufacturer-listed marks; regional and installation conditions apply.
Know when a door or window opens.
DoorProtect Jeweller monitors the position of a door or window using a detector and magnet. An opening becomes an event in the Ajax system, helping protect entrances and other accessible openings. Its compact two-part design fits around the frame, with the installation gap chosen for reliable detection.

Know when an opening changes.

Opening detection
A reed switch registers when the supplied magnet moves away. Mount the detector and magnet on the correct fixed and moving parts, keeping the closed-position gap within the manual’s limits.
DoorProtect detects opening. It does not provide the built-in shock and tilt sensing of DoorProtect Plus.
Bring an additional contact into the system.
External NC input
The detector’s terminals can accept a supported third-party wired detector with a normally closed contact. An installer checks its contact type, wiring and event behaviour before connecting it.
DoorProtect cannot power a third-party detector. Supply any required power separately.
Know when a visitor arrives.

Chime while disarmed
Together with a compatible Ajax siren, the opening detector can announce a door opening while the system is disarmed. Different short patterns can identify different entrances.
Chime requires an Ajax siren and configuration; the opening detector itself does not sound the notification.
Power for everyday protection.

Replaceable battery power
A replaceable preinstalled CR123A battery supports up to seven years of operation. Check battery state in the app and keep access for servicing.
Battery life depends on settings, use, temperature and signal conditions. Respond to the app’s low-battery notification.
A secure link to your system.
Jeweller communication
Jeweller carries alarms, status and commands between this detector and a compatible hub or range extender. The two-way link uses encryption and device authentication.
The stated range is up to 1,200 m in open space. Walls, metal and the actual installation reduce usable coverage.
Reach the areas your system needs.

Plan around walls and distance
Test the signal where the detector will be installed. If coverage is insufficient, select a compatible range extender; an Ethernet-equipped model provides another route back to the hub.
Range extenders are optional equipment. Check supported models and quantities against the exact hub before planning coverage.
Know that protection is working.

Device state in the app
The detector reports its condition to the hub. Communication, power and tamper information help identify a device that needs attention. Clear device and room names make an alert easier to act on.
Professional alarm monitoring is a separate service. Notification and connection-loss timing depend on system settings and connectivity.
Protection that also watches itself.

Removal alerts
The tamper reports attempts to remove the detector from its mounting panel. Secure the mounting arrangement and check that the event reaches the intended users.

Authenticated communication
The hub checks the detector’s identity during communication. Encryption protects the exchanged data, while authentication helps reject a device attempting to impersonate it.
Installed for your actual space.

Connect
Scan the device QR code to add it to a compatible hub. Assign a clear name and the room or area where it will operate.

Communication
- Jeweller communication technology
- Two-way system communication for the functions specified for this model.
- Radio signal range
- up to 1,200 m Between detector and control panel (or range extender) in an open space.
- Encrypted communication
- Encrypted device communication.
- Frequency hopping
- Radio communication uses frequency hopping to prevent interception and jamming.
Detection
- Sensitive element
- 1 reed switch
- Magnets
- small and big one come in the set The small magnet operates at a distance of up to 1 cm from the detector, and the big magnet — up to 2 cm. Attach the magnet on the right side of the detector.
- Protection against reed switch chattering
- The detector ignores vibrations lasting up to 0.15 s.
- Input to connect an additional detector
- Wired detector with the normally closed (NC) contact type.
- Chime
- When the system is disarmed, the siren makes a special sound to notify that the opening detectors are triggered.
Sabotage protection
- Tamper alarm
- Notifications on attempts to detach the detector from the surface or remove it from the mounting panel.
- Protection against spoofing
- device authentication
- Communication loss detection
- after 36 s Depends on the Jeweller or Jeweller/Fibra settings.

For your installation
- Confirm the supported control panel, device software and regional radio version; test coverage at the final installation position.
- Do not install the detector using both magnets at the same time. The detector recognizes only one magnet on one side of the detector. Attach the magnet to the moving part of the door (window) to the right of the detector. The side to which the magnet should be attached is marked with an arrow on the detector’s enclosure. The device is designed for indoor use only.
