By-alarm Plus
1. General characteristics
The By-alarm Plus system is latest-generation hybrid burglar alarm system dedicated to protecting people and property from unauthorised access. It comprises a set of wired
devices/peripherals (connected to the system by BUS) and a set of via-radio devices/peripherals.
The system stands out due to the following features:
• modular
• contextual
• flexible
Modular
A By-alarm Plus system is created by using solely the devices required for the needs of the end user. No peripheral is compulsory, the functions with greatest added value can
be implemented by purchasing devices only where required and the system is expandable according to installation requirements. For instance, a system without keyboards
can be created, even though this entails certain restrictions. The radio frequency part, which is also optional, comprises transceivers connected to the control unit via BUS
and signal repeaters; the latter are used to extend the range of “coverage” and are connected via radio to the reference transceiver.
Contextual
Using the By-alarm Pus Manager programming software, the installer can only operate on the system elements that they are actually using, avoiding the display/editing of
parameters or unnecessary functions. For instance, if the system envisages the use of 2 areas, the installer will be able to see and programme all the parameters consist-
ent with just the 2 areas used even though the control unit manages 10 of them. When configuring a specific type of detector, the software shows the installer only those
parameters and options that are consistent with the chosen article since it analyses the context and hides/shows only the parameters of interest.
For the end user the benefits are the same: a keypad will present the user with only those controls actually consistent with the current status of the system. If for instance all
the areas are disabled, the keypad will never have a control available for disabling.
Flexible
The system operates in the same way as a PLC which activates, deactivates, enables, disables, notifies events and statuses that the control unit detects and all the interac-
tions are programmable. The via-radio part, which is also completely optional, is managed with the same criteria, procedures and functions as wired peripherals/devices in
order to standardise the interfaces for the installer and user. In addition to the classic functions of a burglar alarm system, it is for instance possible to create a simple access
control, or to generate interlinked automations and it is also possible to set automatic activations/disconnections that the user can edit at their discretion. With the appropriate
authorisations, a user can also create new users (operation usually permitted only for the installer in current burglar alarm systems).
1.1 Main components of the By-alarm Plus system
• Control unit
It identifies the central processing unit. It consists of the main card, available in 3 versions and this component is necessary for the operation of the By-alarm Plus
system.
• BUS
it is a communication channel consisting of a normal cable with 4 conductors, 2 for the power supply and 2 for data transfer. Each device (also referred to as a pe-
ripheral) can be connected to the BUS in star configuration without the need for end-of-line resistors; this makes it extremely easy to use since a peripheral can be
connected wherever a BUS cable is present without the need to make in-out connections.
• By-alarm Plus Manager Software
This is the software intended for the installer on Microsoft PC. It is designed to configure the system, set all the parameters, save all the systems created and perform
complete monitoring of the system to display, in dedicated sections, the status of peripherals, areas, detectors, outputs, battery levels, radio signal levels, voltages
and absorptions.
• Peripherals
It identifies the various elements that can be connected to the control unit which allow the running of various functions, specific to each type of peripheral. They are
connected to the control unit via BUS. The system allows the routing of each peripheral, both using the By-alarm Plus Manager software as well as using a procedure
on the control unit, in order to assign it to the system configuration. Each peripheral has a unique QR-code in order to detect any unauthorised replacements. The
peripherals which can be connected to the control unit via BUS are as follows:
- LCD keyboards
- Actuators
- Expansions
- LTE communicator
- Sirens
- Transceivers
- BUS isolators
• LCD keyboards
They are distinguished by an LCD graphic display, 5 signalling LEDs, a keypad and other parts which differ depending on the type of keyboard. Thanks to the display,
LEDs and keypad, the user can completely control the system, observing its status and operating all the controls. The articles are:
- LCD keypad art. 03817
- LCD keypad with actuator and 2 I/O terminalsart. 03818
• Actuators
They are quipped with 4 LEDs to display certain system statuses and to perform control operations. Using the transponder keys and with the aid of the LEDs, the user
is in a position to select the control to send to the system. The art. is:
- Actuator art. 03824
• Expansions
These are peripherals with 5 completely programmable I/O terminals which can be connected to detectors (zones) and actuators (outputs). The articles are:
- Expansion in open enclosure art. 03808
- Expansion in closed enclosure art. 03819

By-alarm Plus
• LTE communicators
They notify users and installers of system events via the mobile network operators. They operate in the 2G, 3G and 4G networks that the peripheral automatically
selects (according to the best technology available in the location of the system installation) and send voice messages and text messages. The user may also send
text messages to the peripheral to give the system controls. The articles are:
- LTE communicator art. 03810
- LTE communicator with buffer batteries art. 03820
• Sirens
They carry out the optical-acoustic signalling generated by burglary events. They are equipped with piezoelectric elements that generate high sound power and have
an illuminator/flashing lamp with high-efficiency LEDs. The articles are:
- BUS outdoor siren art. 03826
- Outdoor siren art. 03827
• Radio interfaces
They are devices on BUS which allow the structure of the system to be extended using via-radio communications between various elements (detectors, remote con-
trols, sirens). They operate in the dedicated frequency band centred on 868 MHz. The articles are:
- Transceiver in plastic enclosure art. 03831
- Transceiver on plastic bracket art. 03832
• BUS isolators
They carry out the regeneration of BUS signals and allow the galvanic isolation between two BUS sections. It is the only peripheral for which the connection to the BUS
occurs on 4 terminals dedicated to the incoming BUS and on another 4 terminals dedicated to the outgoing BUS. The articles are:
- Isolator art. 03822
- Isolator with 12V@1A power supply unit art. 03823

How to create a system
2. How to create a system
Below is a description of the different ways a By-alarm Plus system can be created. In actual fact each method is not mutually exclusive from the next and so the installer
will decide the most appropriate one to use.
IMPORTANT: The By-alarm Plus Manager programming software is always indispensable.
CAUTION: The default PIN for the installer, which is necessary to access via the keypad or the software, is 9999.
2.1 Off-line installation
In this mode, after performing the appropriate surveys at the system installation site, the installer performs the entire configuration of the system on a bench using the
software and so without the need to power the elements/peripherals/devices. The procedure is as follows:
1. The installer has everything they need, all the packs and the Qr-codes of all peripherals/devices
2. None of the devices has been installed, all the peripherals/devices are on the bench
3. Open the By-alarm Plus Manager software and create a new system
4. Perform the configuration of all the wired peripherals using the QR-codes
5. Where present, perform the configuration of all devices radio using the QR-codes
6. Set the parameters for the whole system and save it in the PC, assigning it a name
7. Perform the installation (fixings and wiring) of the control unit and of the peripherals/devices in the site the system is to be created in
8. Power up the system
9. Send the system created previously and saved in the software to the control unit.
The system is now up and running.
2.2 On-site installation and routing of wired and radio peripherals/devices using the By-alarm Plus manager software
In this mode, the installer has already installed (fixed and wired) all the peripherals/devices in the installation site. The procedure is as follows:
1) During installation of the wired peripherals on BUS and of the via-radio devices, keep all the Qr-codes and identify their respective position in the system (for instance,
the keypad with QR-code 2C40000236F032 is the one at the entrance; the magnetic contact with QR-code R03000AKB6F035 is the one for the kitchen window,
etc.)
2) Power up the system
3) Open the By-alarm Plus Manager software and create a new system
4) Use the QR-codes of each peripheral on BUS to assign it to the system
5) Where present, use the QR-codes of each via-radio device to assign it to the system
6) Use the software to set the parameters for the entire system and, as they are gradually defined, send them to the control unit
7) When programming is complete, save the system in the PC and assign it a name
The system is now up and running.
2.3 On-site installation and routing of wired peripherals without software
In this mode, the installer has already installed (fixed and wired) all the peripherals/devices in the installation site.
Consider that the By-alarm Plus Manager software will still be necessary to complete the configuration of the entire system. The procedure described herein only per-
forms rapid routing of the peripherals on BUS using push buttons and LEDs present on the control unit card.
The procedure is as follows:
1) During installation of the wired peripherals on BUS, keep all the QR-codes and identify their respective position in the system (for instance the keypad with QR-code
2C40000236F032 is the one installed at the entrance, etc.)
2) Power up the system
3) Go to the control unit and set it to ENROL status (device routing phase start): press and hold down (approximately 2 s) the SERV/ENR push button until the corre-
sponding red SERV/ENR LED starts flashing
4) In sequence, press the ENROL push button on each expansion (art. 03808 or 03819)
5) In sequence, approach a transponder key to each actuator (art. 03824)
6) In sequence, press the ENROL button on each keypad (art. 03817 or 03818)
7) Press the ENROL button on the transceiver (art. 03831)
8) In sequence, press the ENROL button on each BUS siren (art. 03826)
9) At the end, briefly press the SERV/ENR push button on the control unit to exit the routing phase
i) N.B. Points 4) to 8) do not necessarily need to be performed in sequence; the operation described can be performed using any peripheral, for instance by pressing
the ENROL push button on an expansion, then the ENROL button on a keypad, then the ENROL push button on a siren and so on.
ii) The peripherals are acquired by the control unit and routed via a progressive number (1, 2, 3, etc.) depending on how the installer performs the sequence.
iii) Keep in mind that each type of peripheral is routed starting with index 1 (so it is possible for you to have a keypad, an expansion, a siren and an actuator at the
same logical address, but it is not possible for you to have two keypads at the same logical address).
10) Open the By-alarm Plus Manager software and perform a system reading in order to transfer the programming stored in the control unit to the PC
11) Since you marked the physical position of the peripherals, assign a description/label to each peripheral using the software
12) Use the software to set the parameters for the entire system and, as they are gradually defined, send them to the control unit
13) When programming is complete, save the system in the PC and assign it a name
The system is now up and running.

3.3 System sizing criteria
This paragraph illustrates the flow diagram with the criteria to follow for the correct sizing of the system in relation to the desired range and to the consumption levels of
the devices in the By-alarm Plus system.
CAUTION: For the correct sizing of the system, always consider the maximum consumption condition; this condition varies according to the number of devices
present in the system and to the conguration created.
Generally speaking, we recommend you pay attention to the condition of total enabling and the active alarm condition.

on steady = control unit under MAINTENANCE (**, see the paragraph concerning the MAINTENANCE status hereunder); certain functions are forbidden, such
as the processing of alarms and sabotages
off = control unit fully operating normally, all the processing is active
flashing = control unit in peripheral on BUS acquisition phase; the control unit waits for the installer to perform the enrolment procedure of keyboards, actuators,
expansions, etc. which are connected to the BUS.
3.6.2 EXE LED
During normal control unit operation, the LED flashes blue, increasing and decreasing its brightness progressively. When exiting the installer menu or at the end of
programming from a PC or during the factory resetting or during firmware reprogramming of the control unit and peripherals, the LED may take on the steady ON
or OFF status for the duration of the operation in progress, at the end of which it should start to flash again. (*) The LED on or off outside the above-mentioned
situations is an indication of a blockage in the running of all the control unit functions (ask for assistance!).
3.6.3 BUS LED
During normal control unit operation and if the system has at least one peripheral on BUS, the LED flashes yellow irregularly, not periodically. When exiting the in-
staller menu or at the end of programming from a PC or during the factory resetting or during firmware reprogramming of the control unit and peripherals, the LED
may take on the steady ON or OFF status for the duration of the operation in progress, at the end of which it should start to flash again. If the system is completely
devoid of peripherals on the BUS, the LED takes on the OFF status; this condition outside the above-mentioned situations is an indication of the blockage of the
BUS, which can be confirmed by verifying the loss of interactivity with readers, expansions or keyboards.
3.6.4 POWER LED
The lit LED indicates the presence of the power supply. If the LED is off, the primary power supply is missing; the control unit will continue to operate until the flat
battery disconnection threshold (9.5V) is reached.
3.7 Push buttons
The following push buttons are present on the control unit card:
• RESET to reset the control unit and restore the factory settings
• FACTORY to reset the control unit and restore the factory settings
• SERV/ENR to launch the learning phase
3.8 ATS categories
The By-alarm Plus controls constitute, either individually or in combination with devices/peripherals, an SPT (Supervised Premises Transceiver) usable to create an ATS
(Alarm Transmission System) according to the definitions set out in standards EN 50136-1 and EN 50136-2.

All the details can be found in the instruction sheets for the above articles.
A separate line from the electrical distribution board is needed to power the control unit. This line must be protected by disconnection and protection devices.
CAUTION: Take great care when connecting the primary source. Electric shock hazard.
Install the disconnection device in an easily accessible place outside the equipment. The gap between contacts must be at least 3 mm. The recommended disconnec-
tion device is a circuit breaker with a C trip curve and maximum rated current of 16 A.
The site earthing system must comply with the current regulations.
1. Route the power supply cables through the cable outlet hole.
2. Connect the mains power supply to the corresponding terminals. To comply with the safety standards, the phase conductor must be connected to the “L” terminal
and the neutral conductor must be connected to the “N” terminal.
3. Ensure that safety extra-low voltage or signal conductors cannot touch points at hazardous voltages. Use a cable tie to secure the conductors together and fasten
them securely to one of the cable hooks on the bottom of the cabinet.
N.B.: Do not strengthen the ends of stranded conductors with soft soldering at the points in which they are subject to contact pressure.
4. Crimp the earth conductor to the ring terminal provided.
5. Secure the cable with the ring terminal to the earthing stud using the nut provided.
Connecting the buffer battery
The plastic enclosure can house a 12V 7Ah lead battery (not provided).
Take great care to observe the battery polarity:
• black cable = negative
• red cable = positive
For the battery connection, use the dedicated connection cable supplied with the control unit card.
Connect the cable to the control unit through the corresponding connector on the power supply unit.
CAUTION!
The control unit recharges and supervises the status of the buffer battery. The battery efciency is controlled by dedicated tests every 4 minutes. In the event that
the battery is not efcient, in other words the control unit detects a voltage below 10.4V, the “Flat Battery” event is generated, which is restored in the event that
the voltage exceeds 11.4V. In this case the yellow LED on the keyboards will light up. To display the failure on the keyboard display, press the info button, which
will become available
Temperature probe
A temperature probe is available to adjust the battery charging voltage to compensate its temperature. Using this probe prevents the battery from overheating, which
would damage it.
To connect the temperature probe, proceed as follows:
• Disconnect the battery.
• Connect the temperature probe to the connector on the power supply unit
• Secure the temperature probe to the battery in such a way as to ensure good heat transfer.
3.11 Opening and closing the control unit
To gain access to the control unit, proceed as follows:
• On a keypad, long press push button , enter the PIN and press OK: access to the installer menu prevents activation of the outputs and any notifications pro-
grammed in correspondence with the control unit opening.
• Open the cover on the enclosure or remove it.
• Perform any maintenance/other work
• Close the cover.
• Exit the installer menu.

By-alarm Plus
The control unit
3.12 Connecting the PC
This can be done in the following ways:
• USB: this is a direct connection to the control unit via the USB port.
The connection operation depends on the installation of the drivers for communication via USB which are normally available on PCs where Microsoft® Windows®
is installed.
• LAN networks: this type of connection occurs via the gateway art. 03812.
Communication operation depends on the configuration of the network itself. You should therefore check with the network administrator.
Refer to the By-alarm Plus Manager software manual for connection details.
3.13 SERVICE/MAINTENANCE status
The SERVICE/MAINTENANCE status is used during the system configuration phases. When the control unit is in SERVICE/MAINTENANCE mode, it is completely
operational with the exception of the following functions:
• all the outputs and the recording of events activated in correspondence with the events listed below are forced to standby and, in the presence of such events, will
not be activated;
- alarm or zone and area sabotage
- peripheral sabotage
- control unit removal/tampering sabotage
To set the control unit to SERVICE/MAINTENANCE status, briefly press the SERV/ENR push button; the corresponding red LED will light up.
To exit the SERVICE/MAINTENANCE status, briefly press the SERV/ENR push button again; the corresponding red LED will turn off.

Connecting the peripherals to the control unit bus
4. Connecting the peripherals to the control unit bus
Connection of peripherals to the control unit is with a 4-wire (or more) shielded cable.
Caution: Connect the shield to one of the earth (or GND) terminals at the control unit end only, and ensure that it follows the entire BUS without being connected
to earth at any other point.
Connection to the BUS is done on the “+ D S -” terminals present on the peripherals.
D+ –S
D+ –SD+ –S
D
8 9 107
+ –S
D+ –S
The sizing of the BUS line, in other words the distribution of the peripherals and the use of cables to connect them, should be done according to various design factors,
in order to guarantee the correct transmission of signals of the “D” and “S” conductors and of the power supply provided by the “+” and “- ” conductors.
These factors are:
• The current absorption of the connected devices.
In the event of insufficient power supply from the BUS line to the peripherals and sensors, it can also be provided by external power supply units.
• Type of cables.
• Speed of communication on the BUS.
This parameter can be set using the By-alarm Plus Manager software. The communication speeds are: 125kbs, 250kbs.
• Number and distribution of isolators (art.03822, 03823).
To increase the reliability and extension of the BUS, you need to use isolator devices.
The section of the cables used affects the dispersion of the conductor signals.

For correct isolator installation, the branch of the BUS where the isolator is located needs to be sized according to the number of peripherals connected to this branch
and to their total current absorption. This absorption should therefore be compared to the “Maximum control unit absorption” value.
Another characteristic to take into account is the line length downstream of the isolator up to the next isolator or to the end of the line. The table below shows the indica-
tive values of this length in relation to the BUS speed

The length (L) indicated here corresponds:
• in the case of a single line, to the length of the cables between an isolator and the subsequent peripherals or between two subsequent isolators.
• in the case of branched lines, to the sum of the lengths of all lines between an isolator and the subsequent isolators or that end with peripherals.
The figure below illustrates a sample system with BUS speed of 125kbps.

4.2 Connecting isolators
The isolators have a dual purpose:
- to regenerate the electrical signals of the BUS which deteriorate in the presence of long sections or in the presence of multiple connected devices;
- isolate the BUS itself galvanically both to protect it from tampering and for the correct management of the additional auxiliary power supplies
The articles available in the range are:
art. 03822 basic isolator with the possibility of galvanic isolation of the power supply;
art. 03823 isolator with galvanic isolation of the power supply and regeneration of power supply 13.8V@1A.

Connecting alarm sensors and balancing
5. Connecting alarm sensors and balancing
Connecting sensors (detectors) and balancing them depends on their type and on the protection degree you wish to achieve. Sensors can be powered:
• by terminals [+AUX/12V] and [-/earth] present on the control unit
• by terminals [+AUX/12V] and [-/earth] present on the expansions, art. 03808 and 03819
• by terminal [+/12V] and by terminals [-/mass] present on the keyboards, art. 03818
• by any source of 12V auxiliary power supply provided it has the earth reference (GND) in common with the earth reference of the control unit.
N.B. The terminals constantly provide 12 V but in the By-alarm Plus Manager software, they can be used as programmable outputs; in this case, they must NOT be
used to power sensors.
The default resistors used and provided and the related colour bands are:
• 3.3kΩ 1/4 W orange-orange-red gold
• 4.7kΩ 1/4 W yellow-purple-red gold
• 15kΩ 1/4 W brown-green-orange gold
CAUTION!
The resistors used must be connected directly to the terminals of the sensors, not to the terminals of the control unit or of the peripherals.
Generally speaking, the level of protection provided by the type of balancing used is shown in the following table
BALANCING
N.O.
(norm. open)

(norm. closed)
Single balancing
(one EOL resistor)
Double/triple balancing
(two or three EOL resistors)
Level of protection very low low medium high
5.1 N.C./N.O. balancing
The Normally open and Normally closed balancing is easy to achieve but are equally unavoidable. No resistors are used for which only two statuses of the terminal which
they are connected to can be detected:
• standby
• alarm (violated/activated)
Below is an illustration of the connection structure for the N.C. /N.O. balancing This connection can typically be used for both the terminals of the alarm and sabotage/
tamper signals of the detector.

To detect sabotage/tampering, you need to connect the related signal to the terminal configured as MAINTENANCE type GENERAL ZONE
5.2 Single balancing
Single balancing (often indicated as single end-of-line resistor or with single EOL) uses a single resistor for which three statuses of the terminal which it is connected to
can be detected:
• standby
• alarm (violated/activated)
• sabotage (via short-circuit)
Below is an illustration of the connection structure for the single balancing.

In case a, 2 separate terminals are used for the alarm and tamper signals.
In case b, a single terminal is sufficient for the alarm and tamper signals to be detected correctly.
This connection can typically be used for both the the alarm and sabotage/tamper signals of the detector.
As for the single balancing, for the detection of sabotage/tampering on a dedicated terminal, you need to connect the signal to a 24H input

Connecting alarm sensors and balancing
Note
The level of protection of the single balancing is as safe as the double balancing if the sabotage contact of the sensor is connected to a balanced input.
5.3 Double balancing
Double balancing (often indicated as double end-of-line resistor or double EOL) uses two resistors, for which four statuses of the terminal which they are connected to
can be detected:
• standby
• alarm (violated/activated)
• sabotage (via short-circuit)
• sabotage (via wire cutting/detector opening)
Below is an illustration of the typical connection structure for double balancing.

5.4 Triple balancing
Triple balancing (often indicated as triple end-of-line resistor or triple EOL) uses three resistors, for which six statuses of the terminal which they are connected to can
be detected:
• standby
• alarm (violated/activated)
• anti-masking
• alarm + anti-masking
• sabotage (via short-circuit)
• sabotage (via wire cutting/detector opening)
This balancing is also used to manage two separate detectors on a single terminal; in this case the anti-masking signal is replaced by the alarm signal of the second
detector.
