Two reed switches

Two magnets of different sizes

Tamper against detaching the detector from the surface

Holding screw to secure the detector’s casing

Removable device board

Fixing points for convenient detector installation

Perforated parts for wire routing
High-end reed switches for reliable opening detection
Superior DoorProtect Fibra features two durable reed switches, allowing the magnet to be positioned on either side of the detector (right or left). This flexibility provides installers with more options for wire routing, as the detector functions effectively irrespective of magnet placement. Housed in resilient plastic capsules, reed switches remain intact during transportation, even in case of drops.

Easy integration with third-party detectors
Superior 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, Superior 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.

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 module2 that extends the Fibra line
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 detector consuming only up to 0.036 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.

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 informed immediately to provide necessary services.

Next-level protection of Fibra line
Introducing LineProtect, the module designed to protect an Ajax hub and connected wired devices from sabotage when intruders cause overvoltage, short circuits, apply 110/230 V~, or use stun guns.
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 programming required — everything is available out of the box.

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 several perforated parts for cable routing. The magnet can be installed on either the right or left side: two reed switches detect opening equally fast regardless of the magnet placement.

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.
