RK100BS-EX
The RK100BS-EX detector is a newly developed optical beam microprocessor-based smoke detector,
composed of a Transmitter (TX) and a Receiver (RX), which bases its operation on the interaction between
the smoke present in a room and a infrared beam emitted by the Transmitter.
Normal installation involves fixing the Transmitter on a wall and on the opposite wall of the room to be
protected, fixing the Receiver.
For a correct installation, we recommend reading and scrupulously following the instructions listed below.
The excellent operating results of the device, will largely compensate for the time taken to read these
instructions.

2.2 - The RK100BS-EX detector can be installed in areas with danger of explosion: zone 1 - zone 2 - zone
21 - zone 22.
It must not be installed in a hazardous area classified as zone 0.
2.3 - The technical data indicated on the container must be respected
2.4 - Changes to the product are not permitted
2.5 - The RK100BS-EX detector must be installed only if it is completely intact
2.6 - Only EDS spare parts must be used
2.7 - Ordinary and extraordinary maintenance operations must be carried out only by qualified personnel
with the approval of "expert" personnel
2.8 - The national safety and accident prevention regulations and the instructions indicated with the warning
triangle in this technical manual must be strictly observed.
4 - PRECAUTIONS BEFORE INSTALLATION
4.1 - All installation and maintenance operations must be carried out when an explosive
atmosphere is present
5 - AUTHORIZED STAFF
5.1 - All installation, calibration, start-up, maintenance and operation checks of the RK100BS-EX detector
must be performed only by qualified personnel. These people are qualified by virtue of their experience,
participation in specialization courses, knowledge of the regulations in force, properties and technical
specifications of the product and its use. These people are therefore able to avoid errors or damage and
ensure optimal operation of the product. The installation operations indicated below must be carried out in
a time interval during which there are no hazardous conditions in the environment.
5.2 - The RK100B-EX detector must be used in accordance with the technical data and information in this
manual regarding use, installation and environmental and operating conditions.
66 6 - INSTALLATION
6.1 - For the installation of the RK100BS-EX detector we recommend using the following elements in
addition to the normal instruments (drill, expansion caps, etc.):
• 1 - 7 mm C or star key
• 1 - Tester. We recommend an analog hand pointer.
6.2 - Remove the cover of the TX and RX (porthole).
6.3 - Install the Transmitter at a distance from the ceiling within 10% of the height of the room to be protected
(UNI 9795 standard). This distance can be varied by the designer if there are particular environmental
conditions. Wall mounting must be carried out carefully using the 4 holes provided on the container. If the
wall is in masonry, 4 expansion plugs are enough. It is extremely important that the fixing wall is rigid and not
subject to deformation.
6.4 - Install the Receiver on the opposite wall and at the same height as the Transmitter. It is not necessary that

EDS - INFORMAZIONI TECNICHE
5
the Receiver is positioned perfectly in front of and perpendicular to the reflector (corner errors up to 5 ° in all
directions are allowed). For reasons of cable economy, we recommend installing the Receiver in the position
closest to the control panel.
6.5 - Introduce the cables inside using ATEX certified cable glands
7 - CONNECTION CABLES
7.1 - The reduced current of the device (20 mA with normally not attracted alarm relay and 30 mA with attracted
relay) allows the use of cables with small sections. We recommend, for distances up to 500m, a shielded cable
with 8 wires + screen [2x0.75 mmq (for power supply) + 6x0.22 mmq (for alarm relay contacts)].
In this way it is possible to carry away:
• the alarm signal (terminals C1-N1)
• the pre-alarm / fault signal (terminals C3-N3)
• the analogue signal (signal level) - (terminal 9 - SIGN)
The cable shield must be connected as shown in fig.8.
The box must be connected to the earth.
8 - ELECTRICAL CONNECTIONS
8.1 - To make the connection to the TX and RX terminal board, since the space inside the enclosure is very
small, it is necessary to remove the 4 fixing screws of the electronic board and position it adequately to
make the electrical connections on the terminal board. Then reinstall the card in its initial position.
Connect the appliance cables as shown in the diagrams in fig.6-7-8.
The symbols shown represent the following:
• (V+) (V-) - power terminals 11 - 30 Vdc (TX and RX)
• C1-N1 - normally closed contact of the Alarm relay. The connection is valid when the detector is not in
alarm state and the jumper JP2 is in position 2- 3. If the jumper JP2 is positioned between 1-2 the contact
is normally open. Terminals C1-N1 are without voltage
• C3-N3 - normally closed contact of the Fault / Fault relay. The connection is valid when the detector is not
in a fault state and the jumper JP4 is in position 1- 2. If the jumper JP4 is positioned between 2-3, the
contact is normally open. Terminals C3-N3 are without voltage. The Fault relay is normally energized (for
intrinsic safety)
• SIG - terminal with analogue output 0-5V of the detector. To be used only during calibration.
Figures 6-7-8 show the diagrams of the terminal board and the classical diagram for connection to a
control unit with terminated lines
9 - OPERATION
9.1 - The RK100BS-EX detector is equipped with a smoke detection circuit produced by a fire:
• DARKENING - circuit sensitive to darkening.
This circuit bases its operation on the decrease in the intensity of the infrared beam, along the optical path
between the TX and RX, caused by the smoke

EDS - INFORMAZIONI TECNICHE

10 - OPTICAL ALIGNMENT WITH POINTER
LASER BLP-100
10.1 - The BLP pointers are installed on board the EDS optical detectors in order to speed up the optical
alignment operations between TX and RX (for barrier devices) or between the detector and its optical
reflector (for reflection reflectors)
10.2 - The BLP laser pointer is an accessory that makes the installation of EDS detectors very fast. It allows
a fast primary alignment. However, it is always necessary to carry out the electrical alignment (optimal
signal adjustment). After the electrical alignment, the pointing of the Laser may differ slightly from the
initial one.
10.3 - Warnings
10.3.1 - During the operations described below, take extreme care not to deform the small card that supports
the Laser pointer by impact or pressure, on pain of its misalignment with the optics of the detector. The
Laser BLP pointer has been perfectly collimated with its optic on the optical bench during the assembly
of the detector
10.3.2 - Attention! - when the Laser is switched on, it is not absolutely necessary to point the beam at the
eyes or to look directly at the beam, getting on axis with it
10.3.3 - In the case of long distances between TX and RX, it is advisable to carry out aiming in conditions
of reduced environmental illuminance
12 - TX SETTING
11.1 - On the Transmitter (TX) turn the SW3 selector to one of the positions 1-2-3-4 (fig.5) in relation to the
distance between the TX and RX with reference to the following table:
position 1 ....... distance 25 - 50m
position 2 ....... distance 50 - 75m
position 3 ....... distance 75 - 100m
position 4 ....... distance 100 - 120m
11.2 - Power up the TX transmitter (the blue TX LED will emit a pulse every 10 seconds) and turn on the
pointing laser using the switch (see photo)

EDS - INFORMAZIONI TECNICHE
7
11.3 - Use the V1-V2-V3 bolts (fig.5) to orient the lens of the TX transmitter, so that the Laser beam hits the
RX receiver lens on the opposite wall.
When this happens, the lens of the receiver has an intense bright red spot.
In this way the TX is optically aligned with the receiver RX.
11.4 - on the receiver RX orientate the optic using the bolts V1-V2-V3 so that the red light dot on the white
disk behind the lens and representing the focal point of the incident laser beam, falls to the center of the
white disk (small black hole) where the sensor photo-element is present.
After this operation TX and RX are optically aligned
11.5 - On the TX turn off the alignment laser, close the lid and proceed with the next instructions of the
detector as per manual
12 - RX SETTING
12.1 - On the RX the electrical signal calibration operations must be performed according to the sequence
indicated below
12.2 - Setting the jumpers on the RX receiver
JP1 - jumper to activate / deactivate the optical alignment procedure. To activate the optical alignment
procedure, the JP1 jumper must be inserted in position 2-3 (ON). To deactivate the optical alignment pro-
cedure and thus make the detector operational, the JP1 jumper must be disengaged position 1-2 (OFF):
• JP1 position 2-3 ON .... alignment procedure activated
• JP1 position1-2 OFF ... alignment procedure deactivated
JP2 - JP4 jumpers to set the output contact respectively of the Alarm relay and normally closed NC fault or
normally open NA (see fig.1)
The RK100BS-EX detector is supplied with normally closed NC set contacts. For the Alarm relay the indication
of JP2 is valid if JP7 is in the OFF position.
JP5 - jumper to activate the alarm memory function or deactivate this function (to obtain the detector Auto
Reset)
• in position 1-2 memory off. When the alarm status ceases the detector resets itself (Auto Reset)

EDS - INFORMAZIONI TECNICHE
8
• in position 2-3 memory inserted. In the event of an alarm the detector remains in alarm until the voltage is
removed for 5 seconds
JP6 - jumper for microprocessor Reset
JP7 - jumper for setting the Alarm relay operating mode normally energized or de-energized
• JP7 ON - Alarm relay normally energized (in case of alarm it is de-energized). In this case the indication of
the JP2 jumper shown above is the reverse
• JP7 disabled OFF - Alarm relay normally de-energized (in case of alarm it is energized).
In this case the indication of the JP2 jumper indicated above is concordant
12.3 - Move the Initial Set jumper JP1 (fig.9) to the 2-3 ON position (Alignment) to activate the
initial setting phase
12.4 - The blue and red LEDs will begin to flash in a certain sequence to indicate to the operator the signal
level. In order for the receiver to be initially set so as to guarantee regular operation, the signal level must be
adjusted between 4 - 4.8V using the P1 trimmer.
12.5 - Keep in mind that the cover of the receiver (porthole) when installed will cause a decrease in the
signal due to the absorption of the front glass. In order for the receiver to work smoothly, the measured
signal with the lid inserted must be between 4 and 4.8V.
12.6 - To achieve this result it is therefore necessary to momentarily screw the cover and observe through
the porthole, the flashing of the red and blue LEDs positioned in front of the optic. The flashing of these
LEDs gives an indication of the signal level.
12.7 - Observe the status of the blue and red LEDs on the RX.
The signal level indication is as follows:
• 1 flash of the blue LED indicates 1 Volt
• 1 flash of the red LED indicates 0.5 Volt
• if the signal is less than 0.5V the blue and red LEDs are OFF
• if the signal is between 0.5-1 V, the red LED flashes 1, then 2 seconds remain off and then repeats the
sequence
• if the signal is between 1-1.5 V, the blue LED flashes once, then it remains OFF for 2 seconds and then
repeats the sequence
• if the signal is between 1.5-2V the blue LED flashes 1, after the red LED flashes 1, then 2 seconds remain
OFF and then repeats the sequence
• if the signal is between 2-2.5 V the blue LED flashes 2 times, then 2 seconds remain OFF and then
repeats the sequence
• if the signal is between 2.5-3V the blue LED flashes 2 times, after the red LED flashes 1, then 2 seconds
remain OFF and then repeats the sequence and so on up to 4 V
• if the signal exceeds 4 V, the blue LED flashes with increasing frequency as the signal increases up to
4.7V
• when the signal exceeds 4.7V and is between 4.7V - 4.9V, the blue LED lights up steadily. This is the
optimal calibration position

EDS - INFORMAZIONI TECNICHE

12.9 - Then act on trimmer P1 until the signal level indicated by the LEDs and displayed through the porthole,
is between 4 - 4.8V (blue LED flashing or fixed). After a few attempts the result is reached.
This is the optimal calibration position.
This procedure is important because it will ensure a perfect functioning of the detector for a long time.
Warning! - if to obtain this signal level it is necessary to adjust the trimmer in an anti-clockwise
direction almost to zero or, if turning the trimmer with small shifts you notice large variations in
the signal level, it means that the signal sent by the transmitter is too powerful.
In this case it is necessary to decrease the power of the TX by acting on the selector SW3 and turning it
towards lower steps (for example if SW3 was set on 3, rotate it on 2 or even on 1). After carrying out this
operation, the adjustment of the P1 trimmer to obtain the 4 - 4.8V becomes simple and not critical.
12.10 - Attention!
If the signal is adjusted beyond 5V, the detector goes into saturation and the blue and red LEDs light up
steadily. Therefore acting on P1, it is necessary to adjust the signal back to 4-4.8V so that the red LED
turns off and only the blue remains lit (avoid saturation).

• if the signal exceeds 4.9V, both blue and red LEDs light up steadily. This indicates saturation.
12.8 - The following table summarizes the above data.

EDS - INFORMAZIONI TECNICHE
10
Warning! - the adjustment between 4 - 4.8V is not critical.
The procedure indicated above is the optimal one.
However it is sufficient that the signal is just above 4V and the blue LED is flashing or on steady,
to have a good calibration.
The microprocessor will automatically compensate for the inaccuracies in the calibration.
However, it is necessary to avoid saturation (red LED lit) because, in this condition, the detector
will not work properly.
12.11 - After carrying out these operations, adjust the alarm level of the circuit sensitive to the Darkening by
acting on the SW2 selector, bearing in mind the following:
• position 1 - low sensitivity - alarm level for dimming at 70% .........................1.5V signal level
• position 2 - medium / low sensitivity - alarm level for dimming at 60% ........ 2.0V signal level
• position 3 - medium / high sensitivity - alarm level for dimming at 50% ....... 2.5V signal level
• position 4 - high sensitivity - alarm level for dimming at 40% .........................3.0V signal level
12.12 - Sensitivity must be adjusted according to the environmental situation.
Normally the calibration must be done for medium sensitivity, but in the case of dusty and perturbed
environments, it will be good to use a lower sensitivity.
13 - SELF-COMPENSATION
13.1 - The internal electronics of the detector is equipped with a special signal compensation circuit. If the
detector is installed inside a particularly dusty room, the dust deposited on the front of the TX and RX
causes a decrease in the signal. This problem is automatically eliminated by the self-compensation circuit.
14 - FAULT OUTPUT
14.1 - As already indicated in chapter 4, the contact of the fault and fault relay is available on the RX terminal
board. This relay is normally energized and is de-energized if at least one of the following conditions is met:
• the signal falls below the calibration value by 90% (optical beam completely interrupted by an obstacle)
• the autocompensation circuit has reached the limit (when this occurs it is necessary to carry out maintenance
of the detector)
• circuit operating anomaly (means failure of some component)
15 - ALARM MEMORY AND DATA
15.1 - The RK100BS-EX receiver is equipped with an alarm memory that can be enabled / disabled using
the JP5 jumper (fig.1):
• jumper JP5 in position 1-2 - memory not activated (OFF)
• jumper JP5 in position 2-3 - memory activated (ON)
When the memory is activated, if the detector goes into Alarm, the alarm output relay and the frontal red
LED remain activated until the alarm stops and the voltage is not removed for more than 5 seconds.
When the memory is not activated, if the detector goes into alarm, the alarm output relay and the front LED
turn OFF as soon as the alarm stops.
