Guardian for doors, windows, and valuables
DoorProtect Plus Fibra is designed to detect intrusion and burglary attempts, offering comprehensive coverage for doors, windows, skylights, and vaults. The detector, equipped with two reed switches as opening sensors, features protection against chattering in its operation. 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 Plus Fibra features two durable reed switches, guaranteeing decades of trouble-free operation. Two reed switches allow the magnet to be positioned on either side of the sensor (right or left). 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.

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.

Easy integration with third-party detectors
DoorProtect Fibra has terminals for connecting a third-party wired NC detector. This allows an installer to enhance system reliability with any NC detector, whether newly installed or already in place, such as motion, opening, or vibration detectors. For example, DoorProtect Fibra enables you to integrate an existing third-party3 opening detector into the system.

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.

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.
