Operating principle

installation, it consists of two blocks: a detector and a magnet. The detector is mounted on a frame or ﬁxed part of the structure, and the magnet is mounted on a movable ﬂap or a sliding part.

The sensitive element of the detector is a reed switch (sealed contact). This is a small ﬂask with an open contact group inside. When a magnet is brought to the detector, a magnetic ﬁeld is generated and the detector contacts are magnetized, attracted, and closed. Opening the ﬂap or door moves the magnet away from the reed switch, which opens the circuit, and the detector detects opening.
It takes a single magnet for the DoorProtect Fibra detector to create a magnetic ﬁeld. Use a small or large magnet depending on the conditions at the installation site.
DoorProtect Fibra has two reed switches, which allows you to install a magnet on both the left and right side of the detector. Note that DoorProtect Fibra works with one magnet on one side only. If magnets are installed on both sides, the detector will not detect opening correctly.

A small magnet acts at up to 1 cm, and a large magnet up to 2 cm.

The DoorProtect Fibra detector in the armed mode, when triggered, transmits an alarm signal to the hub in 0.15 seconds, activates the sirens connected to the hub, and notiﬁes the user and the security company.
Users know exactly where motion is detected. The notiﬁcations contain the name of the hub (name of the guarded object), the name of the device, and the virtual room to which the detector is assigned.

The detector doesn’t go into armed mode instantly. The time it takes to switch to armed mode depends on two factors: exit delays (speciﬁed in the detector settings) and the hub— detector ping interval (Fibra settings, the default value is 36 seconds). In the ﬁrst case, the delay is set by an administrator or a PRO-user with administrator rights. In the second case, the delay occurs because it takes one ping interval for the hub to notify the detector about the transition to armed mode.

Fibra data transfer protocol
The detector uses Fibra technology to transmit alarms and events. This is a two-way wired data transfer protocol that provides fast and reliable communication between the hub and the rest of the devices. Using the bus connection method, Fibra delivers alarms and events instantly, even if 100 detectors are connected to the system.
Fibra supports block encryption with a ﬂoating key and device authentication at every communication session to prevent sabotage and device spooﬁng. The protocol provides for regular polls of detectors by the hub at intervals of 12 to 300 seconds to monitor communication with all devices and display their statuses in real-time in Ajax apps.

Connecting a third-party wired detector
A third-party wired NC detector (normally closed, or NC detector) can be connected to DoorProtect Fibra. It can be any type of detector: motion, opening, or vibration.
DoorProtect Fibra cannot power a third-party detector. It should be connected separately. For the type and voltage of the third-party detector, refer to the device documentation or contact the manufacturer’s technical support.

How to connect a wired detector to DoorProtect Fibra

Sending events to the monitoring station
The Ajax system transmits events to Ajax PRO Desktop or a Central Monitoring Station (CMS) in the formats of SurGard (Contact ID), SIA (DC-09), ADEMCO 685, and other proprietary protocols. A complete list of supported protocols is available here.

Which CMSs can the Ajax system be connected to

Types of DoorProtect Fibra events that are transmitted to PRO Desktop and the CMS:

Opening sensor alarm.
Third-party NC detector alarm.
Tamper alarm/recovery.
Loss/recovery of connection between the detector and the hub.
Permanent deactivation / activation of the detector.
Unsuccessful attempt to arm the security system (with integrity check enabled).

When an alarm is received, the operator of the security company monitoring station knows exactly what happened and precisely where to send a fast response team on the site. Addressability of each Ajax device allows you to send not only events to the PRO Desktop or to the CMS but also the type of the device, the name of the device, and the virtual room to which the detector is assigned. Note that the list of transmitted parameters may differ depending on the type of CMS and the selected protocol for communication with the monitoring station.

The device ID, the loop (zone) number, and the line number can be found in itsstates in the Ajax app.

Selection of the installation site for the detector
When choosing where to place the detector, consider the parameters that affect its normal operation: Fibra signal strength, length of the cable for connecting the detector, and the opening detection zone.
Consider the placement recommendations when designing your facility’s security system. Design and installation of the security system should be carried out by professionals. A list of authorized oﬃcial Ajax partners is available here.

Design and preparation
For the system to work correctly, it is important to properly design the project and install all devices correctly. Failure to follow the basic installation rules and recommendations of this manual may result in detector malfunction, false alarms, or loss of connection with already installed devices.
When designing the layout scheme of the detectors, consider the wiring diagram of the power cables laid on the site. Signal cables must be laid at a distance of at least 50 cm from the power cables when lying parallel, and, if they intersect, it must be at a 90° angle. Detectors are connected in sequence if you connect multiple devices on the same line.

The maximum number of connectable devices for the Hub Hybrid is 100

For facilities that are under construction or renovation, cables are laid after the main wiring of the facility. Use protective tubes to organize and secure the cables; ties, clips, and staples can be used to anchor them.
When laying cables externally (without mounting them inside the walls), use an electric channel raceway. Raceways should be no more than half-ﬁlled with cables. Do not allow cables to sag. The raceway should be hidden from view if possible —for example, behind furniture.

We recommend laying cables inside walls, ﬂoors, and ceilings. This will provide greater security; the cables will not be visible, and it will be impossible for an intruder to access them.

When selecting a cable, consider the length of the connection lines and the number of detectors to be connected; these parameters affect the signal strength. We recommend using shielded copper cables with a high-quality insulation layer.
Observe the bend radius when installing. It is speciﬁed by the manufacturer in the cable speciﬁcations. Otherwise, you risk damaging or breaking the conductor.
Be sure to check all cables for bends and physical damage before installation. Perform the installation in a way that minimizes the possibility of damage to the cables from the outside.

**The DoorProtect Fibra working distances***
When mounting the detector on perpendicular planes, use a small magnet. The distance between the small magnet and the detector should not exceed 1 cm.
Use a big magnet if parts of DoorProtect Fibra are mounted on the same plane. The table below provides information about the working distances between the big magnet and the detector.

DoorProtect Fibra has two reed switches. This allows both left- and right-hand installation of the magnet. DoorProtect Fibra works with one magnet on one side only. If magnets are attached on both sides, the detector cannot detect the opening correctly.

Relatively to the detector, the magnet can move along three axes: X (X1), Y, or Z. It depends on the DoorProtect Fibra installation location. For example:

X- axis (or X1): on the roller shutter.
Y- axis: on the sliding door.
Z- axis: on the window.
— for small magnet all measurements will be reduced.

Do not exceed the boundary distance between the detector and the magnet. This may cause false alarms or detector malfunction (it will not react to closing/opening of the door or window).

Signal strength and cable length
The Fibra signal level is determined by the number of undelivered or corrupted data packages over a certain period. The icon on the Devices tab indicates the signal strength:

Three bars — excellent signal strength.
Two bars — good signal strength.
One bar — low signal strength, stable operation is not guaranteed. Crossed out icon — no signal.

The signal strength is inﬂuenced by the following factors: the number of devices connected to one line, the length and type of cable, and the proper connection of the wires to terminals.

Check the Fibra signal strength before ﬁnal installation of the detector. With a signal strength of one or zero bars, we do not guarantee stable operation of the device.

The permissible cable length depends on its type, material, and the method of connecting the detectors. When connected via the Beam connection (Radial wiring) using the U/UTP cat.5 (4×2×0.51) twisted pair, the wired connection length can reach up to 2,000 meters.
When devices are connected via the Ring connection method, the maximum cable length is 500 meters in case of using a twisted pair.

How to check the wire connection length
Connecting devices using the Ring connection method will be available with future OS Malevich updates. Hardware update of Hub Hybrid won’t be required.

Detection zone
When choosing where to place the detector, conduct a Detection Zone Test verify the operation of the device and to ensure that the detector responds correctly to opening and closing of a door or a window.

Do not install the detector

Outdoors. This can lead to false alarms and detector failure.
With two magnets at a time. The detector recognizes only one magnet on one side of the detector — left or right.
Inside premises with temperature and humidity outside the permissible limits. This could damage the detector.

Do not install DoorProtect Fibra with two magnets at a time. The detector recognizes only one magnet on one side — left or right.

Installation and connection
Before installing DoorProtect Fibra, make sure that you have selected the optimal location and that it meets the conditions of this manual. Cables must be hidden from view and located in a place that is diﬃcult for intruders to access to reduce the likelihood of sabotage. Ideally, mount them in the walls, ﬂoor, or ceiling. Before the ﬁnal installation, conduct tests of the detection zone and the Fibra signal strength.

DoorProtect Fibra is connected with a 4-core cable: two cores for powering the device (+24V and GND) and two cores for data transmission (line A and line B).
When connecting to the detector terminals, do not twist the wires together; solder them. The ends of the wires that will be inserted into the detector terminals should be tinned or crimped with special tips. This will ensure a reliable connection. Follow safety procedures and regulations for electrical installation work.
