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.

Both the monitoring station and security system users instantly receive notifications about events. The information provided includes time, device name, event type, and room location4.

Authentication against detector spoofing

Authentication against detector spoofing

During each communication session, the hub authenticates the device using its unique parameters. If any parameter fails the authentication check, the hub ignores device commands.

Protection against short circuits

Protection against short circuits

Fibra protocol, combined with a special digital algorithm, provides robust protection against unnoticed short circuits of the device. If someone attempts to short-circuit it, the device promptly notifies of a malfunction. The hub informs the Central Monitoring Station (CMS) and users about the incident.

Encryption of transmitted data

Encryption of transmitted data

All data the system stores and transmits is protected by block encryption featuring a dynamic key. This encryption deters intentional sabotage attempts on the detector.

Regular polling

Regular polling

The device regularly exchanges data with the hub. At minimal polling settings (3 data packages in 12 seconds), it takes 36 seconds to detect communication loss and notify the security company and users about the incident.

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.

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 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.

Security opening sensor for alarm

Opening sensors help protect the space by detecting the opening of windows and doors. By installing opening detectors, it is possible to avoid the intrusion into the premises under protection, theft and damage to property.

The principle of operation of sensors for opening windows and doors

Opening sensors are autonomous or work as part of a security alarm. Standalone devices are often equipped with a siren activated after the detector has detected an opening. The sensor helps to draw the attention of the environment to the incident and scare off the intruder. Security opening sensors as part of the security system transmit an alarm signal to the control panel, which, in turn, reports the incident to the system's users, the security company's monitoring console, and turns on the sirens. Door opening sensors are often mounted in the entrance area or in places where a high level of protection is needed: vaults, rooms with securities, etc. Windows are protected in places easily accessible to thieves on the lower and upper floors of the building.

How to choose an opening sensor for a security system

For the correct choice of the opening sensor for the alarm, you need to determine the place of use and the device's purpose.
  • Opening sensors should be small and inconspicuous.
  • The case of the device must not be damaged. The integrity of the opening sensor is important since cracks can affect performance. It is worth ensuring that the sensor package has all the wires, fasteners and batteries.
  • Decide the type of device connection. Wireless opening sensors do not require cabling and can be installed in a finished interior. Wired models of door and window opening sensors provide for laying communications but are considered more reliable. The second type will work in warehouses with thick load-bearing walls and partitions without harming contact with the signalling central.

Wired window and door opening sensor DoorProtect Fibra

Wired bus detector DoorProtect Fibra is designed for indoor installation. The device supports the connection of a third-party NC sensor. The DoorProtect Fibra opening detector with a wired network connection works with the Ajax alarm system. Data received by the sensor is transmitted to the security system's control panel via the secure Fibra protocol. The communication range of the devices is up to 2 kilometres when connected via a U/UTP cat.5 twisted-pair cable.

The principle of operation of the wired sensor for opening windows and doors from Ajax

The wired DoorProtect Fibra opening sensor is connected to the Hub Hybrid alarm control panel via a bus and operates using the Fibra protocol. The main components of the device: are a detector and magnet. The sensor is mounted on the frame or fixed part of the window or door, and the magnet is mounted on the sliding part of the movable sash. The DoorProtect Fibra opening sensor has a sensitive element - a sealed contact or reed switch. The contact is a flask with an open contact group inside. When the magnet approaches the detector, a magnetic field is formed, and sensor contacts are attracted by the influence of the magnet and close. When the door opens, the circuit opens, and the sensor detects the fact of opening. The DoorProtect Fibra wired opening sensor needs one magnet to create a magnetic field. Depending on the conditions at the installation site, a large or small size magnet is used.

Features of the wired opening sensor DoorProtect Fibra

The Ajax wired door and window opening sensor has the following features:

Protection against opening and dismantling

A tamper protects the device from removing the device from the mounting and damage. When you try to remove the opening sensor, the control panel will notify alarm users about the incident.

Possibility to connect the alarm system to the monitoring by the security company

Security companies accept for control only certified security systems, whose security equipment has been thoroughly tested for reliability and performance in various conditions.

Speed ​​of response to an incident

The DoorProtect Fibra wired opening sensor sends an alarm signal to the alarm central in 0.15 seconds in armed mode. The control panel will notify system users and the security company and activate sirens depending on the settings.

Sensor targeting

Thanks to the targeting of the opening sensors, the user and the security company know in which room the door or window has opened. The incident report contains the name of the device, the name of the control panel, and the space to which the opening detector is connected.

Testing the performance of the opening sensor

For the correct choice of the installation location of the window and door opening sensor, testing of the security device is provided. DoorProtect Fibra tests will help determine the installation location with a high signal level for the correct operation of the window and door opening sensor.

Installation and configuration of DoorProtect Fibra

Before installing a wired DoorProtect Fibra opening sensor, it is essential to make sure that the installation site meets all requirements:
  1. The wires must be hidden from prying eyes - so the attacker will not notice the security device.
  2. Fibra signal strength tests and detection area tests need to be done.
Wired window and door opening sensor DoorProtect Fibra can be sold, installed and administered only by accredited Ajax partners.
