GlassProtect Fibra is a wired glass break detector. It responds to glass breaking
using a built-in electret microphone. The detectorʼs microphone using the
DualTone digital algorithm only responds to sound vibrations characteristic of
the sound of glass breaking, cutting off false alarms.
In the armed mode, the detector instantly transmits an alarm signal to the hub
when it detects a break. The hub activates connected sirens, runs ,
and noties users and the security company.
Users will know where a glass break has been detected. The notications
contain the name of the hub (name of the guarded facility), the name of the
device, the type of alarm, and the to which the detector is assigned.
Protection from false alarms
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 an
impact 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 facility.
GlassProtect Fibra will not react on a break if a lm is glued to the glass: anti-shock, sun-
protective, decorative, or other. To detect 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
wired data transfer protocol to provide 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 oating key block encryption 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 the Ajax apps, the protocol
involves regular device polling by the hub with an interval of 12 to 300seconds.
Connection of a third-party wired detector
A third-party wired detector with a normally closed (NC) contact type can be
connected to GlassProtect Fibra. This can be any detector: motion, opening, or
vibration.
GlassProtect Fibra will not power the third-party detector. The detector should
be connected separately. To learn the type and input voltage of the third-party
detector, refer to the device documentation or contact the manufacturerʼs
technical support.
Sending events to the Central Monitoring Station (CMS)
The Ajax security system can transmit events and alarms to the ,
monitoring app as well as the Central Monitoring Station (CMS) via SurGard
(Contact ID), SIA DC-09 (ADM-CID), ADEMCO 685, and other proprietary
protocols. A list of supported protocols .
GlassProtect Fibra can transmit the following events:

Which CMSs can the Ajax security system be connected to?

When an alarm is received, the operator of the security company monitoring
station knows what happened and where to send the fast response team.
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
GlassProtect Fibra is mounted on a vertical surface with the bundled screws. All
the necessary holes for fastening in the enclosure have already been made. The
detector is intended for indoor installation only.
When choosing a location for GlassProtect Fibra, consider the parameters that
affect the correct operation of the detector:
Consider the placement recommendations when designing your facilityʼs
security system. The security system should be designed and installed by

Fibra signal strength
The Fibra signal strength is determined by the number of undelivered or
corrupted data packages over a certain period. The icon in the Devices
tab in the Ajax apps indicates the signal strength:
The following factors affect the signal strength:
available here
Outdoors. This can lead to false alarms and detector failure.
Close to sirens and speakers. This can lead to false alarms of the break
detector.
In places with fast air circulation — for example, near fans, open windows, or
doors. This can lead to false alarms of the break detector.
In places where objects or structures can interfere with the passage of
sound to the detector. For example, in places where the curtains will be
between the window and the GlassProtect Fibra. This may prevent the
detector from registering glass breakage.
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.
Crossed out icon— no signal, stable operation is not guaranteed.
The number of devices connected to one Fibra line.
Cable length and type.
The correctness of the wire connections to the terminals.

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.
Detection zone
When choosing a place to install the detector, run a to check
the operation of the device and determine the sector in which the detector
registers glass breaking.
The location of the detector determines the area to be monitored and the
effectiveness of the security system. When deciding where to install the
detector, consider the directivity of the microphone and the presence of
obstacles interfering with the microphone operation.
The microphone of the detector identies glass breaks at a distance of up to 9
meters. To detect a break, the detector should be positioned at an angle of up to
90 degrees to the window or windows.

Designing
To correctly install and congure security system devices, it is important to
design the security system properly. The design must consider the number and
types of devices at the object, their exact location and installation height, the
length of Fibra wire lines, the type of cable used, and other parameters. Tips for
designing wired Fibra systems are available .

Topologies
Currently, 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 is not required.
Beam connection (Radial wiring)occupies one bus output of the hub. In the
event of a line break, only the segment that remains physically connected to the
hub will function. 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 deactivated. The ring recongures into two lines, which
continue to operate normally. Users and the security company will receive
notication about the break.
Beam (Radial wiring) Ring
Occupies one bus output of the hub.
Up to 8 lines on the same hub.
Up to 2,000 m of wired communication for the
same line.
A termination 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 termination resistor is installed at the end of
the line.

Both topologies can be used on the same hub. For example, you can use 2 ring
and 4 beam (Radial wiring) connections on the same control panel.
Different types of devices can be connected to a single Fibra line. For example,
you 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 in the
diagram below. Branching of lines is not allowed.
When using the Beam (Radial)topology, be sure to install a 120 Ohm
terminating resistor at the end of the line (included in the hub kit). The
termination resistor is connected to the signal terminals of the last detector on
the line.
Cable length and type
The maximum range of a wired connection using the Beam (Radial)topology is
2,000 meters, and using the Ring topology — 500 meters.
Recommended cable types:
U/UTP cat.5 4 × 2 × 0.51. The conductor material is copper.
Signal cable 4 × 0.22. The conductor material is copper.

If you use a different type of cable, the communication range for wired connections 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
real practice, we have developed a communication range calculator of Fibra
lines (in progress). 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.

Preparing for installation
Cable arrangement
When preparing to lay cables, check the electrical and re safety regulations in
your area. Strictly follow these standards and regulations.
It is safest to route cables inside walls, oors, and ceilings: this way they will be
invisible and unavailable for intruders. It also ensures their greater durability: the
The maximum current that Hub Hybrid can supply in total for all Fibra lines
is 600 mA. The total current consumption of the devices in the system
depends on the type of cable, its length, the type of connected device, the
quality of the connection of conductors, and other factors. Therefore, after
selecting devices, we recommend verifying the project using the
