CombiProtect Fibra is a wired combined motion and glass break detector. In the
armed mode, the detector instantly transmits an alarm signal to the hub when it
detects motion or glass break. The hub, in turn, activates the sirens connected
to the system, runs , and noties users and the security company.
All CombiProtect Fibra alarms and events are recorded in the notication feed of
the Ajax app. Users know where motion or glass break is detected. The
notications contain the name of the hub (name of the protected facility), the
name of the device, the type of alarm, and the to which the detector
is assigned.
The detector doesn’t switch to the armed mode instantly. The time it takes to switch to
the armed mode depends on two factors: delay when leaving (specied in
) and the “hub — detector” polling interval (in Fibra settings; the default value is
36 seconds). In the rst case, the delay is set by a user or a PRO with administrator
rights. In the second case, the hub noties the detector about the transition to the armed
mode not instantly, but the waiting time does not exceed the duration of one polling
period.
Motion detector
Using an IR (infrared) sensor, CombiProtect Fibra identies intrusions by
detecting moving objects with temperatures close to that of the human body.
The digital SmartDetect algorithm eliminates false alarms, relieving users of
unnecessary anxiety, and security companies from false calls of patrol.

settings

In the armed mode, the detector constantly reads the infrared sensor signals.
When motion is detected, CombiProtect Fibra transmits an alarm to the hub and
signals it by ashing the LED indicator (if indication is enabled).
Glass break detector
Glass break detection is provided through an electret microphone. The detector
uses DualTone — a two-stage algorithm to exclude false alarms. To register a
break, the detector must record a dull (low-frequency) sound of a shock and
then aringing (high-frequency) sound of falling fragments in 1.5seconds. Owing
to this algorithm, the detector does not respond to the barking of dogs or cars
passing by the protected object.
CombiProtect Fibra will not react to a break if a lm is glued to the glass: anti-shock, sun-
protective, decorative, or other. To x the break of such glass, we recommend using
detectors with a shock sensor: or
Fibra data transfer protocol
The detector uses Fibra technology to transmit alarms and events. This is a data
transfer protocol that provides fast and reliable two-way communication
between the hub and the connected devices. Using the bus connection method,
Fibra delivers alarms and events instantly, even if 100 devices are connected to
the system.
Fibra supports block encryption with a oating key and veries each
communication session with devices to prevent sabotage and spoong. To
monitor connection with the system devices and display their statuses in Ajax
apps, the protocol involves regular device polling by the hub with a specied
interval.

Pet immunity
When properly installed and congured, CombiProtect Fibra does not respond to
pets up to 50 centimetres tall and weighing up to 20 kilograms.
The detector is installed at a height of 2.4 metres without any obstruction to its
view. For example, in a corner where the view will not be blocked by a closet or
other furniture on which a pet can climb.
It is also important to set the required sensitivity in the :
If the detector is installed below the recommended height, then the pets will
move in the high sensitivity zone. If a sheepdog walks on its hind legs or a small
spaniel gets loose on a chair, the detector can raise a false alarm. The detector
will also raise an alarm if the pet can jump to the level of the detector or move
near it.
detector settings
High — the detector does not respond to cats (up to 25cm tall).
Normal — the detector does not respond to small dogs (up to 35cm tall).
Low— the detector does not respond to pets up to 50cm tall.
Why detectors respond to pets and how to avoid this
How to install CombiProtect Fibra correctly

Temperature compensation
The detector perceives people and other objects as heat spots. The device
monitors these heat spots and, if they move, detects an alarm. Under ideal
conditions, the human body temperature (36.6°C on average) differs from the
ambient temperature. Due to their contrast, the motion detector accurately
captures the movement of a person in space.
In situations where the ambient temperature is very close to the body
temperature, the detector may not operate properly; it may give false alarms or
fail to respond to motion. To offset this factor, we use temperature
compensation.
Temperature compensation is used in all Ajax motion detectors, so
CombiProtect Fibra detects motion over the entire operating temperature range.
Sending events to the monitoring station
The Ajax security system can transmit alarms to the monitoring
app as well as the Central Monitoring Station (CMS) using SurGard (Contact ID),
SIA DC-09 (ADM-CID), ADEMCO 685, and other proprietary protocols. The full
list of supported protocols .
CombiProtect Fibra can transmit the following events through the hub to the
CMS:

1. Motion alarm.
2. Glass break alarm.
3. Tamper alarm/recovery.
4. Hub connection loss/recovery.
5. Temporary deactivation/activation of the detector.

When an alarm is received, the monitoring station operator of the security
company knows what happened and where the rapid response unit (RRU) has to
be sent. Addressability of Ajax devices allows sending not only events but also
the type of the device, the name, group, and virtual room assigned to it to the
PRO Desktop and to the CMS. The list of transmitted parameters may differ
depending on the type of the CMS and the selected communication protocol.
The device ID, loop (zone) number, and Fibra line number can be found in
in the Ajax app. The device number corresponds to the loop (zone) number.
Selecting the installation site
CombiProtect Fibra is mounted on a vertical surface or in a corner with the
bundled screws. Drill holes in the SmartBracket mount for installation. The
detector is intended for indoor installation only.
When selecting a location for CombiProtect Fibra, consider the parameters that
affect the correct operation of the detector:

Fibra Signal Strength
The Fibra signal strength is determined by the ratio of the number of undelivered
or corrupted data packages to those expected over a certain period of time. The
icon  in the Devices tab in Ajax apps indicates the signal strength:
2. In places where objects and structures may obstruct the detector’s view. For
example, behind a ower or a column.
3. In places where glass structures may obstruct the detector’s view; it doesn’t
detect movement behind glass.
4. Facing the window to avoid direct sun rays hitting the detector lens. This
can lead to false alarms of the motion detector.
5. Opposite any objects with rapidly changing temperature— for example,
electric and gas heaters. This can lead to false alarms of the motion
detector.
6. Opposite any moving objects with a temperature close to that of the human
body — for example, opposite the swinging curtains above a radiator. This
can lead to false alarms of the motion detector.
7. In places with fast air circulation — for example, near fans, open windows, or
doors. This can lead to false alarms of the motion and glass break
detectors.
8. Close to sirens and speakers. This can lead to false alarms of the glass
break detector.
9. In locations where objects and structures can interfere with the passage of
sound to the detector. For example, in a place where curtains are located
between the detector and the window. This may prevent the detector from
detecting glass break.
10. Inside premises with temperature and humidity outside the permissible
limits. This could damage the detector.
11. In places with low or unstable Fibra signal strength. This may cause
malfunctioning of the detector.
Three bars — excellent signal strength.
Two bars — good signal strength.

The following factors affect the signal strength:
Check the Fibra signal strength before nal installation of the detector. If the signal
strength is as low as one or zero bars, we cannot guarantee stable operation of the
device.

consider the direction of the detector lens, its viewing angles, and the presence
of obstacles to the view of the lens.
The detector can recognize motion at a distance of up to 12 metres. The
direction of the detector lens should be perpendicular to the intended path of
entry into the premises.

Design
detection zone test

To correctly install and congure security system devices, it is important to
properly design the security system. The design must consider the number and
types of devices at the object, their exact location and installation height, the
length of wired Fibra lines, the type of cable used, and other parameters. Tips for
designing Fibra wired systems are available .
Topologies
Ajax’s security systems support two topologies: Beam (Radial wiring) and Ring.
Connecting devices using a Ring topology will be implemented in the next OS Malevich
updates. Hardware update of Hub Hybrid will not be required.
Beam connection (Radial wiring) occupies one bus output of the hub. Only the
segment that remains physically connected to the hub will function in the event
of a line break. All devices connected after the breakpoint will lose connection
with the hub.
Ring connection occupies two bus outputs of the hub. If the ring breaks in one
place, no device will be disabled. The ring recongures into two lines, which
continue to operate normally. Users and the security company will receive
notication of the break.

Beam (Radial wiring) Ring
Occupies one bus output of the hub.
Up to 8 beams on the same hub.
Up to 2,000 m of wired communication for the
same line.
A terminating resistor is installed at the end of
the line.
Occupies two bus outputs of the hub.
Up to 4 rings on the same hub.
Up to 500 m of wired communication for the
same ring.
No terminating resistor is installed at the end of
the line.
Both topologies can be used on the same hub. For example, two Ring
connections and four Beam (Radial) connections on the same control panel can
be used.
Different types of devices can be connected to the same Fibra line. For example,
an installer can connect opening detectors, motion detectors with photo
verication support, sirens, and keypads to the same line.
The devices are connected to the Fibra line one by one, as shown on the gure.
Line branching is not supported.
For the Beam (Radial) topology, be sure to install a 120 Ohm terminating resistor
at the end of the line (included in the hub complete set). The terminating resistor
is connected to the signal terminals of the last detector on the line.
Cable length and type

The maximum communication range for wired connection using the Beam
(Radial) topology is 2,000 metres, and that using the Ring topology is 500
metres.
Recommended cable types:
If using a different type of cable, the communication range for wired connection may
vary. No other types of cables have been tested.
Verication using a calculator
To make sure that the project is calculated correctly and the system will work in
practice, we have developed a .
The calculator helps to check the quality of communication and cable length for
wired Fibra devices with the selected conguration at the system design stage.

Up to 100 devices can be connected to Hub Hybrid (with default settings).

Cable arrangement
When preparing to route cables, check the electrical and re safety regulations
in your region.
It is safest to route cables inside walls, oors, and ceilings; this way, they will be
invisible and unavailable for intruders. It also ensures greater durability; the
cable will be affected by fewer of the external factors that can impact the
natural wear of the conductor and its insulating layer.
As a rule, security system cables are routed during the construction or repair
stage and after wiring at the object.
If impossible to install cables inside the walls, route them so that the cable is
suciently protected and hidden from prying eyes. For example, in a cable
conduit or a protective corrugated pipe. It is recommended to hide them. For
example, behind the furniture.
We recommend using protective pipes, cable conduits, or corrugated pipes to
protect cables, regardless of whether they are routed inside the wall or not. The
cables should be arranged carefully; no sagging, tangling, or twisting is allowed.
Consider the locations of possible signal interference. If the cable is routed near
motors, generators, transformers, power lines, control relays, and other sources
of electromagnetic interference, use twisted-pair cable in these areas.
Cable routing
When routing cables for a security system, consider not only the general
requirements and rules for electrical installation work but also the specic
installation features of each device: installation height, mounting method, how
the cable is inserted into the enclosure, and other parameters. Before
installation, we recommend reading the section of
this manual.
Try to avoid any deviations from the security system project design. Violation of
the basic installation rules and the recommendations of this manual may lead to
incorrect operation of the devices.
selecting the installation site

Check the cables for bends and physical damage before routing. Replace the
damaged cables.
Cables of the security system devices must be routed at a distance of at least
50 cm from the power cables when laying parallel, and, if they intersect, at a 90°
angle.
Observe the permissible bend radius of the cable. It is specied by the
manufacturer in the cable specications. Otherwise, an installer can damage or
break the cable.
The devices are connected to the Fibra line one by one. Line branching is not
supported.
Preparing cables for connection
Remove the insulating layer of the cable and strip the cable with a special
insulation stripper only. It strips the cable properly without damaging the
conductor. The ends of the wires that will be inserted into the detector’s
terminals should be tinned or crimped with end sleeves. This ensures reliable
connection and protects the conductor from oxidation. Recommended cable lug
sizes: 0.75 to 1 mm².
Installation and connection
Before installing CombiProtect Fibra, make sure that the optimal detector location has
been selected and that it meets the requirements of this manual. To reduce the risk of
sabotage, the cables must be hidden from view and located in a place that is dicult for
intruders to access. Ideally, the cables should be set into the walls, oor, or ceiling.
Before nal installation, run the and .
When connecting to the device terminals, do not twist the wires together; solder
them. The ends of the wires that will be inserted into the terminals should be
tinned or crimped with special end sleeves. This will ensure a reliable
connection. Follow safety procedures and regulations for electrical installation
work.

2 — for cable output from the side of the detector.
3 — for cable output from the bottom of the detector.
4. If the detector is not the last device in the connection line, prepare a second
cable in advance. The ends of the wires of the rst and second cables that
will be inserted into the terminals of the device should be tinned and
soldered together.
5. Run the cable from the hub into the detector enclosure through the hole that
was made.
6. Connect the wires to the terminals according to the gure below. Be sure to
