Product is not available in your region
Guardian for doors, windows, and valuables
DoorProtect G3 Fibra is designed to detect intrusion and burglary attempts, offering comprehensive coverage for doors, windows, skylights, and vaults. The detector is equipped with two reed switches as opening sensors and a magnetometer for protection against magnet spoofing. Two sizes of magnets provide more mounting options. The device also identifies shock and tilt with a built-in accelerometer, protecting the facility even when windows are in airing mode. All in line with the Ajax user experience, ensuring quick and easy installation of the device.

High-end reed switches for reliable opening detection
DoorProtect G3 Fibra features two durable reed switches with a minimum service life of 1,000,000 openings, guaranteeing decades of trouble-free operation. Housed in resilient plastic capsules, these switches remain intact even in cases of drops or transportation, ensuring the detector’s effective functionality irrespective of magnet placement.

Magnetometer prevents sabotage
The integrated high-end magnetometer records local magnetic field data during calibration, allowing the sensor to identify and monitor the installed magnet. Immediate alarms are triggered by any changes in the magnetic field, providing protection against magnet spoofing. The straightforward calibration process and adjustment of sensitivity levels in the app ensure precise interference detection and eliminate false alarms. Plastic spacers in the mounting kit reduce the impact of metal surfaces when the detector is installed, for example, on the vault door.

Immediate detection of threats
The built-in accelerometer responds swiftly to shocks, detecting potential burglary attempts such as door forcing and vault breaking. The shock sensor has three levels of sensitivity, which can be adjusted to match the secured facility specifics. The detector can also ignore a single impact to minimize the risk of false alarms triggered by external factors. Whether there are vibrations from neighboring constructions or heavy passing traffic, the installer can choose the most appropriate settings for accurate detection.

Windows protection in an airing mode
The built-in accelerometer is designed to protect open windows, seamlessly adapting to diverse facility requirements. Installers can select a normal tilt angle for doors or windows, ranging from 5 to 25 degrees. The system swiftly detects even the slightest deviations from the usual position and provides customizable tilt detection durations, ranging from 1 second to 1 minute. In case the tilt angle surpasses the specified threshold for an extended period, the system raises an alarm.

Enhanced security with additional detectors
DoorProtect G3 Fibra has terminals for connecting any third-party wired NC detector, enhancing the reliability of the entire system. For example, an installer can integrate an additional detector operating on a different principle, such as a roller shutter motion detector. When connected to DoorProtect G3 Fibra, it promptly responds to alarms from detectors and cable breakage³.
Use a detector as a doorbell
The Chime feature transforms the combination of an Ajax opening detector and Ajax siren into a shopkeeper's bell. When the system is disarmed, the siren notifies about door openings with one of four available short beep patterns. Pro users can choose the volume of sound, and different patterns can be assigned for separate entrances, making it easy to recognize whether someone entered through the main or a back door.

System supervision
All Ajax devices perform automatic self-diagnosis and report their states to the hub. Essential parameters, including tamper, communication, power supply, and sensor statuses, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for ARCs, security companies, and users. In case of any malfunction or communication failure, an engineer is promptly informed to provide necessary services.

Fibra
Unique wired technology
An Ajax system uses secure two-way communication based on Fibra proprietary protocol. It features encryption and device authentication to prevent sabotage, spoofing, and data theft. Fibra lines are versatile and support connecting different types of devices to one line: sirens, keypads, and detectors with photo verification.
Up to 2,000 m of wired communication with a hub or a module that extends the Fibra line2
One line for different types of devices
Photo delivery via Fibra line without interference
Protection against sabotage and spoofing
Energy efficiency as a priority
Fibra communication requires minimum power consumption, with the module consuming only up to 0.035 W at its peak. Fibra operates on the TDMA principle. Each device has a short time frame to exchange data with a hub, and its communication module remains inactive the rest of the time. This significantly reduces power consumption and helps avoid interferences even when multiple devices communicate simultaneously.

PRO is king
The myth about wired systems being difficult to install is busted. Ajax minimized an expensive, long, and dusty experience for PROs by developing an ultimate set of tools to make the process easy and flexible, from project design to client support and system maintenance. Everything for smooth and quick installation is included. Intuitive Ajax apps help make the device a part of the system, and each device can be reconfigured remotely at any moment. No need for programmers — everything is available out of the box.
Fibra power supply calculator
The online tool provides security engineers with detailed data on devices' power consumption, enabling easy pre-installation assessment of the wired system project. It helps design the project in real time, highlights problem spots, and offers solutions. Upon completion, results can be downloaded as a PDF file.
The installation kit includes all the necessary fasteners. The device board is removable, which makes the connection process more comfortable. For cable management, there are bracings inside the casing and several perforated parts for cable routing.

Accounts for companies and installers
An Ajax system transmits alarms to the PRO Desktop monitoring app or any third-party CMS. The security company receives an alarm notification in less than a second. Notifications include all the necessary information: name of the device, time of the event, and the exact room where the device is located. The security company also receives photo or video verification, capturing the reason for the alarm.
