MotionProtect Fibra is a wired motion detector. Using an IR sensor, the detector
can identify intrusions by detecting moving objects with temperatures close to
that of the human body.
In the armed mode, the detector instantly transmits an alarm signal to the hub
when it detects motion. The hub activates connected sirens, runs , and
noties users and the security company.
All MotionProtect Fibra alarms and events are recorded in the notication feed
of the Ajax app. Users know exactly where motion is detected. The notications
contain the name of the hub (the name of the protected object), the name of the
device, and the to which the detector is assigned.
The detector registers alarms every 5 seconds. That is, 5 seconds is the
minimum interval in which alarms can be sent to the monitoring station and
Ajax apps.
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 (specied in the )
and the “hub — detector” polling interval (in Jeweller/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 delay occurs because the hub noties the detector about
the transition to the armed mode not instantly, but during one polling period.

Fibra data transfer protocol
The detector uses Fibra technology to transmit alarms and events. This is a
wired 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 veries each
communication session with devices to prevent sabotage and spoong. 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 specied
interval.
Pet immunity
When properly installed and congured, MotionProtect Fibra does not respond
to pets up to 50 centimeters tall and weighing up to 20 kilograms.
The detector is installed at a height of 2.4 meters 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 desired 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 even 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 is able to jump to the level of the
detector or move near it.

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 motion detectors respond to pets and how to avoid this
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
MotionProtect 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), ADEMCO 685, and other proprietary protocols. The list of
supported protocols is .
MotionProtect Fibra can transmit the following events:

Which CMSs can the Ajax security system be connected to
1. Motion alarm.
2. Tamper alarm/recovery.
3. Hub connection loss/recovery.
4. 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 you to send 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
MotionProtect 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 MotionProtect Fibra, consider the parameters
that affect the correct operation of the detector:
Consider the placement recommendations when designing the security system
project for your object. The security system should be designed and installed by
professionals. The list of authorized Ajax partners is .

Outdoors. This can lead to false alarms and detector failure.
In places where objects and structures may obstruct the detector’s view. For
example, behind a ower or a column.
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:
The following factors affect the signal strength:
In places where glass structures may obstruct the detector’s view; it doesn’t
detect movement behind glass.
Facing the window to avoid direct sun rays hitting the detector lens. This
can lead to false alarms.
Opposite any objects with rapidly changing temperature — for example,
electric and gas heaters. This can lead to false alarms.
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.
In places with fast air circulation — for example, near fans, open windows, or
doors. This can lead to false alarms.
In places with low or unstable Fibra signal strength. This may cause
malfunctioning of the detector.
Inside premises with temperature and humidity outside the permissible
limits. This could damage the detector.
Three bars — excellent signal strength.
Two bars — good signal strength.
One bar — low signal strength; stable operation is not guaranteed.

Detection zone
When selecting detector placement, run a . This test allows
you to check the operation of the device and accurately determine the sector in
which the detector detects motion.
The location of the detector determines the area to be monitored and the
effectiveness of the security system. When selecting the installation site,
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 meters. The
direction of the detector lens should be perpendicular to the intended path of
entry into the premises.

Detection Zone Test
To correctly install and congure 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 and hybrid systems are available .
Topologies
Ajax 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 recongures into two lines, which
continue to operate normally. Users and the security company will receive
notication 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, you can use two
Ring connections and four Beam (Radial) connections.
Different types of devices can be connected to the same Fibra line. For example,
you can connect opening detectors, motion detectors with photo verication
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 meters, and that using the Ring topology is 500
meters.
