BARRIER OPTICAL BEAM
LINEAR SMOKE DETECTOR
RK100-B
RK100-BS
The RK100-B(S) is a new conception of optical beam smoke detector barrier. It’s composed by a Transmiter and a
Receiver, and bases its working concept on the interaction between the smoke present in a room and an infrared beam
emitted by the Transmitter and directed to the Receiver placed on the opposite wall of the room to be protected.
For a correct installation, we recommend to read and follow our instructions carefully. The excellent working results of the
device will widely compensate the time spent reading these instructions.
1 - QUALIFIED PERSONNEL
1.1 - All the operations of installation, setup, startup, maintenance and verifications of operation of the RK100-B detector
must only be performed by qualified personnell. These people are qualified for their experience, specialization courses,
knowledge of the current standards and of the technical specifications, features and usage method of the product.. These
people therefore are able to avoid errors or damages and assure an optimal functioning of the product.
2 - NORMATIVE REFERENCES
2.1 - For the installation in European Community countries you must follow the EC standard EN54-14 (Fire detection
and fire alarm systems). In extraeuropean countries you must respect the relevant internatiobnal and national standards.
3 - INSTALLATION
3.1 - For the installation of the RK100-B(S) we suggest to use, besides the normal tools (drill, expansion plugs, etc), also
the following elements:
• 1 - 7mm “C” key
• 1 - Tester (we recommend an analog hand Tester or our analog STS01 meter (optional) to be plugged on the special
connector positioned on detector’s board.
3.2 - Remove the TX and RX cover acting on the 4 fixing screws set on the 4 angles of the cover (fig.2).
3.3 - Install the Transmitter at a distance from the ceiling within the 10% of the height of the room to protect. This distance
can be varied by the system designer if particular environmental conditions exist. Wall fixing must be done with care using
the 4 holes provided inside the container. If the wall is a solid masonry one, 4 expansion plugs are enough. It’s extremely
important that the fixing wall or surface is rigid and not subject to deformations.
3.4 - install the Receiver on the opposite wall and at the same height of the Transmitter. It is not necessary that the device
is perfectly in front of and perpendicular to the receiver (angle mistake up to 5 degrees is possible in all directions).
We recommends, for the cables economy, to install the Receiver in the nearest position to the alarm control panel.
3.5 - get the cables inside through the holes obtained breaking the suitable zones marked on the sides of the detector’s
base..

EDS - TECHNICAL INSTRUCTIONS

4 - CABLE CONNECTIONS
4.1 - the low detector’s power consumption (20 mA with normally open alarm relay contact (NO) and 30 mA with
normally closed alarm relay contact (NC), allows to use small size sections cables. We suggest to use a shielded cable with
8 conductors + shield ( 2x0,75 mmq for power conductors + 6x0,22 mmq for the signal conductors) for a distance up to
1 Km. In such way it is possible to get a remote connection of the following signals:
• alarm relay contact (terminals C1-N1)
• turbulence (heat) alarm relay contact (terminals C2-N2)
• fault relay contact (terminals C3-N3)
• analog signal output (terminal SIG) - for level signal measurement from distance
The shield of the cable must be connected as in fig.14.
5 - ELECTRICAL CONNECTIONS AND INITIAL SETUP
5.1 - Connect the device cables as shown on the labels facing the terminal board. The given symbols indicate what follows:
• (V+) - (V -) - supply’s terminals 11 - 30 Vdc
• (C1) - (N1) - normally closed Alarm relay contact. The connection is valid when the detector is not in alarm state and JP2
jumper is in 2 - 3 position. If JP2 is positioned on 1-2 the contact results normally open. C1-N1 terminals are voltage free
• (C2) - (N2) - Turbulence alarm normally closed contact relay. Connection is valid when the detector is not in an alarm
state and JP3 jumper is in 2 - 3 position. If JP3 is positioned on 1-2 the contact results normally open. C2-N2 terminals
are voltage free
• (C3)-(N3) - normally closed Fault relay contact. Connection is valid when the detector is not in fault state and JP4
jumper is in 1 - 2 position. If JP4 is in 2-3 position the contact is normally open. C3-N3 terminals are voltage free.
Fault relay is normally powered (intrinsic safety)
• (SIG) - 0-5V analog output terminal. To use only during allignment.
5.2 - Jumper Settings
JP1- to enter/exit the optical alignment procedure. To activate the procedure of optical alignment JP1 must be in 2-3 (ON)
position. To deactivate the procedure of optical alignment JP1 must be in 1-2 (OFF) position.
• JP1 position 2-3 (ON).......alignment procedure ON
• JP1 posizione1-2 (OFF)... alignment procedure OFF
JP2 - JP3 - JP4 to set the output contacts respectively of Alarm relay, Turbulence relay(if present) and Fault relay to
normally closed NC or normally open NO (cap. 5.1) The RK100B(S)/RK200B(S) detector is normally factory preset
with normally closed NC contacts. For the Alarm relay the indication of JP2 is valid if JP7 is in OFF position.
JP5 - activate the Alarm Memory function or to deactivate that function (detector automatically resets alarm output)
• position 1-2 Alarm Memory OFF. When the detector gets out of alarm condition it automatically resets alarm output
• position 2-3 Alarm Memory ON. In case of alarm the detector’s alarm output persists until power supply is switched off
for at least 5 seconds
JP6 - microprocessor reset (SW reset)
JP7 - selection of Alarm relay operational mode : normally powered or not powered

EDS - TECHNICAL INSTRUCTIONS
6
• JP7 ON - Alarm relay normally powered (in case of alarm the relay gets not powered).
In this case the indication of the JP2 is inverted
• JP7 OFF - Alarm relay normally not powered (in case of alarm the relay gets powered). In this case the indication of JP2
is according to figures 12-13-14 (diagrams of the terminal block and the classical scheme of connection to a control
system to terminated lines)
6 - OPERATION
6.1 - the RK100-B detector is equipped with 2 circuits for detection of the smoke produced by a fire, but the -S versions
only have the obscuration circuit.
• Obscuration - circuit sensitive to Obscuration. This circuit bases its operation on the attenuation of the infrared beam
intensity, along the optical path between the transmitter and the receiver, caused by smoke presence.
• Turbulence (not present in -S version) - circuit sensitive to Turbulence. During the beginning phase of a fire, generally
there are some clouds of smoke and warm air that rise up to the ceiling. When these clouds and warm air intercept the
infrared beam produced by the detector, they cause a perturbation of it, because they generate changes of optical and
physics characteristics in the transmission mean of the infrared beam. This variations are obviously time related.
An suitable circuit has been designed to detect these variations and, when these reach the programmed amplitude and the
duration in time, an alarm signals generated.
The sensitivity of this circuit is independently adjustable to fully satisfy the specific application needs.
The advantage offered by this circuit is a great speed of fire detection, because it is detected in dynamic way in its initial
phase.
7 - OPTICAL ALIGNMENT WITH THE LASER POINTER BLP-100
7.1 - General
7.1.1 - The pointer is installed on board of the RK100-B detector in order to speed the optical alignment operation
between the transmitter TX and the receiver RX
7.1.2 - The BLP Laser pointer is an accessory that makes the installation faster EDS detectors. It allows a fast primary
alignment. But it is always useful to make the electrical alignment (fine adjustment).
7.1.3 - Attention ! - When the Laser it’s switched ON it must not be pointed directly to human eyes and nobody should
watch the optics along the optical axis of the beam.
7.1.4 - Be careful when performing the operations below, avoiding to damage the Laser pcb pressing or shocking it, so
that it remains alligned with the optics.The pointer is factory aligned with the optics on the testing optical bench.
7.1.5 - In case of long path distance between the 2 elements it’s suggested to perform alignment operations in a reduced
light condition environment
7.2 - Fix the transmitter TX firmly on the wall and the receiver RX on the opposite wall
7.3 - Power the transmitter TX detector
7.4 - Turn ON the Laser pointer using the switch

EDS - TECHNICAL INSTRUCTIONS
7
7.5 - Acting on V1-V2-V3 (fig.9) bolts of optical orientation of the transmitter TX (see manual), so that the Laser beam
impinges on the lens of the receiver RX on the opposite wall. When this happens the receiver lens has an intense red light
spot. In this way the TX is optically aligned with the receiver RX.
7.6 - the RX receiver orient the optics using the V1-V2-V3 bolts so that the red point of light on the white disk behind the
lens and is the focal point of the incident laser beam, falling in the middle of white disc (small black hole) which has the
photo-element sensor. After this operation TX and RX are optically aligned
7.7 - Turn OFF the alignment laser and proceed with successive instructions of the detector by this instruction manual
8 - SETUP OF THE OBSCURATION CIRCUIT
Electric signal setup must be performed according to the following sequence:
8.1 - do not power up the TX and the RX
8.2 - on the Transmitter (TX) rotate the selector SW3 in one of the positions 1-2-3-4 (fig.10) according to the distance
between TX and RX with reference to fig.7
8.3 - power up the TX and don’t mount the cover. The Red led of the TX will pulse every 10 seconds
8.4 - on the Receiver (RX) move the alignment jumper JP1 (fig.9) in the position ON (Alignment) to activate the initial
setup operation mode
8.5 - power up the Receiver
8.6 - the Blue led and the Red one will start working in the way described ahead in chap. 8.13. Before going on to this
chapter read what’s following
8.7 - the P1 trimmer (regulation of the signal level) is factory preset to the 50-60% and it corresponds to a signal of 5V at
the maximum distance
8.8 - to get the best results in the following operations, we recommend the use a measuring instrument (Multimeter),
preferably an analog hand type, for better control of the variations of the signal during the setup.
Good results are also obtained using analog meter STS01 (optional), designed for this application, that must be inserted on
the special connector CN4, set on the printed circuit of the detector (v. fig. 11).
If you don’t have a Multimeter or the STS01, you can perform the setup operations anyway evaluating the signal level
with the frontal Leds indications as described in chap.8.13

EDS - TECHNICAL INSTRUCTIONS
8
8.9 - if available, connect a 5V fullscale Multimeter between the SIG terminal and the negative power supply one and read
the analog output signal. Instead of the Multimeter it is possible to use the STS01 meter (optional - fig. 11). If the output
signal is very low it means that the operations of optical alignment described in chapter 5 have not been performed in the
right way and therefore must be repeated
8.10 - the Transmitter emits a conic beam which form and dimension, in relation with the distance between TX and RX,
are explained in figures 5 -6.
It’s important that the Receiver is in the center of the Transmitter conic beam because, under these conditions, even if some
small movements of the wall on which the Transmitter is installed (caused by deformations), the reflector remains always
within the beam and therefore active.
To obtain this, the operations of fine centering with output signal measuring, explained below, must be performed
with care.
8.11 - adjust the signal around 3V acting on the trimmer P1 (fig.9).
Attention! - Whether to get the 3V is necessary to adjust the trimmer counterclockwise to almost zero, or if
turning the trimmer with small movements, you notice big changes on the signal level, this means that the
signal sent by the Transmitter, is too powerful.
In this case it is necessary to decrease the power of the Transmitter by acting on the the SW3 switch and turning it to the
lowest steps (eg if SW3 was set to 3, turn on 2 or even to 1).
After performing this operation, the adjustment of the trimmer P1 to get the 3V, becomes simple and non-critical.
8.12 - search for the maximum output signal optimizing the optical alignment of the Transmitter acting slowly and in
sequence on the 3 screws of regulation V1-V2-V3 present on the optical block.
This procedure takes some time but, if performed well, it assures a perfect operation of the detector for many years.
We suggest to use the following procedure:
• on the TX slowly turn the screw V1 clockwise 1/2 turn and then look at the value of the signal visualized on the
multimeter on RX. If the signal increased (for example from 3V it rised to 3,5V) then again turn the screw V1 of the TX
clockwise and then look at the value of the signal on the RX
• continue with this procedure as long as the signal on the RX increases. When it has the tendency to decrease instead,
stop the operation on the screws V1 of the TX returning to the previous position
• if during the operation the signal overcomes 4,5V, to avoid the saturation, act on the trimmer P1 of the RX to bring
the signal back to 3 V, allowing the best evaluation of the variations of the signal
• after finding out the maximum of the signal acting on the screw V1, perform the same operations on the screws V2 and
V3 of the TX. In such way the best possible position of optical allignment is reached.
This procedure is important because it will assure a perfect operation of the detector for long time
8.13 - if you don't have a Multimeter it is possible to get good results in the optical alignment of the detector as well, looking
at the RX Blue and Red leds indications. Operation is the following:
• 1 flash of the Blue Led: 1 Volt
• 1 flash of the Red Led: 0,5 Volts
• if the signal is smaller of 0,5V the Blue led and Red one are OFF

EDS - TECHNICAL INSTRUCTIONS
9
• if the signal in the range 0,5-1 V the Red led performs 1 flash, remains off for 2 seconds and then it repeats the sequence
• if signal is among 1-1,5 V the Blue led flashes once, remains off for 2 seconds and then it repeats the sequence
• if signal is among 1,5-2V the Blue led flashes once and the Red led flashes once. They remain off for 2 seconds and then
the sequence is repeated
• if signal is among 2-2,5 V the Blue led flashes 2 times, remains off for 2 seconds and then it repeats the sequence
• if signal is among 2,5-3V the Blue led flashes 2 times and the Red led flashes once. They remain off for 2 seconds and
then the sequence is repeated
• same type of indication up to 4 V
• if the signal overcomes 4 V, the Blue led flashes faster and faster as the frequency signal increases up to 4,7V
• when the signal overcomes the 4,7V and in the range 4,7V - 4,9V, the Blue led is continously ON. This is the
position of optimal setup
• if the signal gets over 4,9V the two Blue and Red leds are permanently ON. This is the saturation indication.
The table of fig.8 recaps the leds operation.
8.14 - install the cover of the TX
8.15 - after closing the cover of the TX and performing the operations of fine optical alignment using the Multimeter, the
STS01 meter or the indications of the leds, adjust the output signal on the RX to a level between 4,5-4,9V, slowly turning
the trimmer P1.
When the signal it is included within this range, the Blue led is costantly ON. This it is the position of optimal setup.
If the signal overcomes the 4.9V, the detector goes in saturation and the Blue and Red leds are both ON.
Therefore acting on P1, it is necessary to set the signal between 4.5-4.9V so that the Red led switches OFF and is only
the Blue Led remains ON (to avoid saturation).
Attention! - This adjustment is not critical. The above procedure is optimal, however it is sufficient that the
signal is just above the 4V and the Blue LED is blinking or lit, to have a good calibration.
Avoid, however the saturation (red LED lit).
The microprocessor automatically compensates for inaccuracies in the calibration.
If this signal adjustment is critical or, if turning the trimmer with small movements, you notice big changes on
the signal level, review as described in cap. 8.11.
8.16 - select the alarm threshold level of the circuit sensible to Obscuration acting on the selector SW2 with the following
possible choiches :
• position 1 - low sensitivity - obscuration alarm threshold set to 70%
• position 2 - low to medium sensitivity - obscuration alarm threshold set to 60%
• position 3 - medium to high sensitivity - obscuration alarm threshold set to 50%
• position 4 - high sensitivity - obscuration alarm threshold set to 40%
8.17 - sensibility must be regulated according to the environmental situation. The setting must normally be a medium
sensitivity level, but in case of dusty and perturbed environments it will be useful to set a lower sensitivity level.9

EDS - TECHNICAL INSTRUCTIONS

9 - SETUP OF THE TURBULENCE - (HEAT) CIRCUIT
(not relevant for -S version)
9.1 - The RK100B detector is equipped with a special additional circuit for the detection of air Turbulence (heat). This
circuit is independent from the classic Obscuration one and in particular situations it can be used to increase the performan-
ce of the detector. If these particular situations are not present the Turbulence circuit can be left unused.
9.2 - This circuit is particularly useful when, for environmental reasons, the detector must be installed at distances from the
ceiling higher than the nominal. When the fire begins, it produces smoke clouds and hot air bubbles that go up. When these
bubbles intercept the infrared beam, they perturbate it because they produce a change of the optical-physical characteristics
of infrared beam. These changes are obviusly correlated in time. This circuit is been projected to detect these changes and,
when these changes reach the programmed width and time duration, an alarm signal is generated. The advantage of this
circuit is the quicker fire detection, because the fire is detected in its beginning phase.A typical example is the complete
protection of the dome of a church with important pictures on its surface. The linear optical beam smoke detectors must be
installed at the baseline of the dome and therefore much lower than the ceiling. In this case using the Turbulence (heat)
detection circuit is very useful to improve the detection.
9.3 - selection of the sensitivity level of the circuit sensitive to Turbulence(heat).
The operation is performed acting on selector SW1 of the RX that has 4 positions (fig.9).
• sensitivity increases from 1 to 4
• position 1 : minimum sensitivity
• position 4 : maximum sensitivity
Regulation must be performed with caution because with an higher sensitivity a quicker response time is obtained, but also
the probability of false alarm is increased. So the sensitivity selection must be done according to the environmental
conditions. If these conditions are good, an high sensitivity regulation is possible. If in the environment, because of the
normal working conditions, dust's clouds, vapor or smoke are systematically produced, it will be necessary to adjust the
sensitivity to a lower level, so that these factors doesn't generate false alarms.
10 - AUTOCOMPENSATION
10.1 - the inside electronics of the detector is equipped with a special function of autocompensation of the signal. If the
detector is installed inside a particularly dusty place, the dust that is deposited on the front of the TX and RX causes a drop
of the output signal level. This problem is automatically eliminated by the autocompensation.
11 - FAULT OUTPUT
11.1 - the Fault relay contact is available on the terminal block of the RX. This relay is normally activated and will be
deactivated if at least one of the following conditions are verified:
• the output signal falls below the 90% preset value (optical beam completely interrupted by an obstacle)
• the circuit of autocompensation has reached its limit (when this happens it is necessary to do some maintenance on the
detector)
• operation fault (detectors’s circuit malfunction)
Attention: the current standards indicate that the fault output can be used for remote signaling, but must not be used for
inhibiting the alarm signal
11.2 - Total Obscuration Option
It is possible to activate a function for rapid total obscuration (<1 sec, 90%) that activates only the fault output (30 second
delay) and not the alarm.
This could be useful to indicate that an obstacle was accidentally introduced through the path of the optical beam.
This operational mode is only working when total obscuration is rapid (<1 sec).

EDS - TECHNICAL INSTRUCTIONS
11
To activate this function operator must insert the JP8 jumper (fig. 9).
Test of this function can be done with a piece of opaque material quickly covering the transmitter or receiver.
After around 30 seconds, the fault output should be activated.
12 - ALARM MEMORY AND CONFIGURATION DATA
12.1 - the receiver of the RK100-B(S) is equipped with alarm Memory that can be activated / deactivated with the JP5
jumper (fig.9):
• jumper JP5 in position 1-2 - memory deactivated (OFF)
• jumper JP5 in position 2-3 - activated (ON)
When the alarm Memory is activated, if the detector gets in alarm, the alarm output relay and the frontal Red led remain
activated until the alarm condition gets off and power supply is removed for at least 5 seconds.
When the memory is not activated, if the detector gets in alarm the alarm output relay and the Red frontal led are deactivated
as soon as the alarm condition gets off.
12.2 - memory of configuration and settings data.
In case of default of power supply the internal memory retains the data. When the power supply is back the detector, after
a setup time of 2 minutes, returns to normal operation
13 - DETECTOR’S ACTIVATION
13.1 - on the RX, put the jumper of initial Setup JP1, in OFF ALI (mark on circuit) position (alignment OFF)
13.2 - the Blue alignment led flashes in a certain way (2 slow flashes - a delay - 2 fast flashes and then this sequence is
repeated)
13.3 - install the cover of the RX. This closing operation must be done within 5 minutes. The signal level will be decreased
because of the attenuation caused by the cover but will be automatically corrected by the microprocessor
13.4 - the inside electronics wait 5 minutes for the installation of the cover and then perform a quick procedure (1-2
minutes) to get the RK100/200B output signal level back to 4,7-5V
13.5 - after this activation procedure, the detector becomes operational. The Blue alignment led switchs OFF and it begins
to flash as described in 13.6
13.6 - every 10 seconds the Blue led will give out a short flash that indicates the normal operation of the detector. In case
of alarm the frontal Red led will light up and remain switched on until the alarm state is present or, if the Memory function
is activated, until the power supply is switched off for at least 5 seconds (v. chap.14)
14 - OPERATIONAL TEST
14.1 - verification of the circuit sensible to obscuration
The verification is done simply darkening the TX or the RX with an opaque screen. After 10 seconds, the RX alarm relay
must activate / deactivate (chap.5.2 - jumper JP7) and the frontal alarm Red led must be switched ON. After that, remove
the screen and the alarm relay must be switched and red led switchs OFF, and the Blue led restarts to flash every 10
seconds.
If the function of memorization is activated (v. chap.14), it is necessary to remove the power supply of the RX for at least
5 seconds to remove the persistence of the alarm indication.

EDS - TECHNICAL INSTRUCTIONS
12
14.2 - verification of the circuit sensitive to Turbulence (if present).
Place and remove an opaque screen in front of the RX several times with the following sequence (dark / light) and selecting
the corresponding sensitivity with SW1 selector:
• position 1.... 2 second dark - 2 second light for 10-12 times
• position 3.... 2 second dark - 2 second light for 8-10 times
• position 2.... 2 second dark - 2 second light for 6-8 times
• position 4.... 2 second dark - 2 second light for 4-6 times
After the correct sequence the Turbulence relay must be activated.
15 - FRONTAL LEDS OPERATION
15.1 - the frontal leds of the RX during the normal operation of the detector, give out the following indications (see fig.9):
• normal operation: the Blue led flashes every 10 seconds
• alarm: the Red led is constantly ON
• limit of compensation, interrupted beam, fault: the Blue led flashes every second
16 - MAINTENANCE
16.1 - the instrument requires an easy and periodic maintenance. It can be programmed or made automatic using remote
signaling of the detector.
During the normal operation and after a certain time from installation, if maintenance is not performed, the detector,
because of the dirt and dust deposited on the front of the covers, gives out a fault output signal, because of the decrease of
the signal below the limit of compensation.
Then it will be time to proceed to cleaning in order to restore the initial optical conditions.
16.2 - The operations to be done are the following :
• remove power supply
• verify the inside terminal board tightening the terminals in the case they are loose
• verify the optical alignment in case some changes of the structure on which the detector is installed. In this case repeat
the operations of chap.8
• perform the cleaning of the front covers of TX and RX.
We suggest to use a wet cloth with water with some trace of soap. Chemical products like alcohol, ammonia and similar
must not be used. The cleaning of the front cover is fundamental for the good operation of the device
• power up the device
17 - CHANGING THE SENSITIVITY
17.1- Afer the installation and after some working time, if you want to modify the sensitivity of the detector, read what
follow:
• remove the cover of the receiver (it is not necessary to power OFF the detector)
• modify the sensitivity acting on the SW2 selector
• close the cover

P1 - trimmer for the regulation of the signal level. Normally regulated to 50-60% that corresponds to a signal of 5V at the
maximum distance
SW1 - selector for the regulation of the sensitivity of the Turbulence circuit. Sensitivity increases from 1 to 4. Position 1,
minimum, position 4, maximum. Not present in -S version.
SW2 - trimmer for the regulation of the sensitivity of the circuit sensible to Obscuration
• low sensitivity - alarm level for obscuration at 70%, position 1
• middle / low sensitivity - alarm level for obscuration at 60%, position 2
• middle / high sensitivity - alarm level for obscuration at 50%, position 3
• high sensitivity - alarm level for obscuration at 40%, position 4
V1-V2-V3 - scews for the regulation of the optical block
CN4 - connector for the STS-01 meter (optional)
JP1 - jumper for activate / deactivate the procedure of optical alignment.
To activate the procedure of optical alignment JP1 jumper must be inserted (ON).
To deactivate the procedure of optical alignment and therefore get the detector operational, the JP1 jumper must be
disconnected (OFF)
• JP1 position 2-3 (ON)......alignment procedure activated
• P1 position 1-2 (OFF)...... alignment procedure deactivated
JP2 - JP3 - JP4 - jumpers to set the relay contacts, respectively of the alarm relay, turbulence and fault normally closed
NC or normally open NO.
• position 1-2 - output contact normally open NO
• position 2-3 - output contact normally closed NC
JP4 must be in position 1-2 to have the contact closed because the fault relay is normally activated.
The RK100-B(S) detector is normally factory preset with closed NC contacts.
For the alarm relay the indication of JP2 is valid if JP7 is in OFF position
JP5 - jumper to activate the alarm memory function or to deactivate such function (to get the auto Reset of the detector)
• position 1-2 memory deactivated. When it stops the state of alarm the detector him autoripristina (Auto Reset)
• position 2-3 memory activated . In case of alarm the shores-bearer remains in alarm until tension is not removed for 5
second
JP6 - jumper of microprocessor Reset
JP7 - jumper to set alarm relay operation normally powered or not powered
• JP7 ON - alarm relay normally activated (in case of alarm deactivated). In this case the indication of the jumper JP2
inverted
• JP7 OFF - alarm relay deactivated (in case of alarm activates). In this case the indication of the jumper JP2 is according
JP8 - Total obscuration Fault option- JP8 ON = activated
