REFLECTIVE TYPE
OPTICAL BEAM SMOKE
DETECTOR
RK100-R - RK100-RS
GENERAL
The RK100-R(S) detector is a microprocessor controlled optical beam smoke detector, that bases its working concept on the interaction
between the smoke present in a room and an infrared beam emitted by a transmitter and reflected by an optical reflector (fig.1).
The normal installation consists in mounting the detector on a wall of the room to be protected and in fixing the FX reflector (FX01, FX02,
FX03, etc depending on the distance- see table in fig.7) on the opposite wall.
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 PERSONELL
1.1 - All the operations of installation, setup, startup, maintenance and verifications of operation of the The RK100-R(S) 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.
1.2 - The RK100R(S) detector must be used according to the tecnical data and to the information of this manual, to the installation and to
the ambiental and operational condition
2 - RELEVANT STANDARDS
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 international and national standards.
3 - INSTALLATION
3.1 - For the installation of the RK100-R detector we suggest to also use, besides the normal tools (drill, expansion plugs, etc), the following
elements:
• 1 - 7mm “C” Key
• 1 - multimeter (we recommend an analog hand Tester or EDS analog STS-01 meter (optional) to be plugged on the special connector positioned
on detector’s circuit.
3.2 - Unscrew the 4 fixing screws (fig. 2) and remove the cover
3.3 - Install the detector 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 - Pass the cables through the holes obtained breaking the suitable zones marked on the sides of the detector’s base.
It is important to use a suitable chock with a connecting pipe to avoid that the dust penetrates inside the device, possibly causing failure
to its correct functioning.

EDS - TECHNICAL INSTRUCTIONS
5
3.5 - Install the FX reflector on the opposite wall at the same distance from the ceiling as the detector. It is not necessary that the device
is perfectly in front of the optical reflector or perpendicular to it (small angle shift are possible in all directions).
4 - CABLE CONNECTIONS
4.1 - The low current of the device (20 mA with normally open (NO) alarm relay and 30 mA with normally closed (NC) alarm relay contact)
allows to use small size section cables. We suggest a shielded cable with 8 conductors + the 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’s possible to take at distance:
•alarm signal (C1-N1 terminals)
•alarm signal for the Turbulence (C2-N2 terminals)
•fault (C3-N3 terminals)
•analog signal output (SIG terminal) - for level signal measurement from distance
The cable shield must be connected as in fig.12
5 - ELECTRICAL CONNECTIONS AND INITIAL SETUP
5.1 - Connect the device cables as shown on fig. 11 and fig.12.
The used symbols indicate what follows:
• (V+) - (V -) - supply’s terminals 11 - 30 Vcc.
• (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) (not present in -S version) - 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. Fault relay is normally powered (intrinsic safety). 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.
• (SIG) - 0-5V analog output terminal. To use during allignment.
5.2 - JP 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 posizion 1-2 (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 RK100-R(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 the 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)

EDS - TECHNICAL INSTRUCTIONS
6
JP7 - Selection of alarm relay operational mode: normally powered (NC) or not powered (NO)
• JP7 ON - relay of alarm normally powered (in case of alarm the relay gets not powered). In this case the indication of the JP2 is inverted
• JP7 OFF - relay of alarm normally not powered (in case of alarm the relay gets powered). In this case the indication of JP2 is according to
figures 11-12 (diagrams of the terminal block and the classical scheme of connection to a control system to terminated lines)
6 - OPERATION
6.1 - The RK100-R(S) detector is equipped with 2 independent smoke detection circuits produced by a fire, but the _S versions only have
the Obscuration circuit.
• Obscuration - circuit sensitive to obscuration.
This circuit founds its operation on the diminution of the infrared ray intensity, along the optic run between the detector and the reflector,
caused by the smoke
• Turbulence (not present in -S version) - circuit sensitive to the Turbulence (heat).
During the beginning phase of the fire, generally there are some clouds of smoke and warm air that climb toward the ceiling. When these
clouds and warm air intercept the infrared ray produced by the detector, they provoke a perturbation of it, because produce a variation of
optic-physics characteristics in the transmission of the infrared ray. This variation is obviously time correlated. An opportune circuit has
been projected to detect this variation and, when these reach the amplitude and the duration in the time programmed, a alarm signal is
produced. The sensitivity and the delay of intervention of this circuit, are independently adjustable so that to fully satisfy the applications
of the technician. 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- Warnings and safety instructions
7.1.1 - The pointer is installed on board of the RK detector in order to speed the optical alignment operation between the detector and the
reflector
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 - 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 factory testing optical bench.
7.1.4 - 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.
7.1.5 - In case of long path distance between the detector and relector, it’s suggested to perform alignment operations in a reduced light
condition environment
7.2 - Fix the detector firmly on the wall and the optical reflector on the opposite wall
7.3 - Apply power to the detector and turn ON the Laser alignment tool using the switch (look at the photo)

EDS - TECHNICAL INSTRUCTIONS
7
7.4 - Adjust optical orientation of the detector acting on the bolts V1-V2-V3 (fig.9), so that the Laser beam is directed on the center of the
reflector on the opposite wall. When this happens, the reflector reflects a bright red light dot.
7.5 - Turn OFF the Laser alignment tool.
7.6 - In this way, the optics of the detector are aligned with their reflector.
7.7 - Proceed with the adjustment of the maximum detector’s signal level as outlined in the following chapter 8.
7.9 - Alternative quick method
- Fix the detector on the wall
- Switch on Laser tool
- Fix the reflector on the opposite wall with the red dot of the Laser in the center of reflector (be careful not to look at the Laser beam)
- Switch off the Laser tool
- Optimize the signal (chapter 8)
8 - SETTING OF THE OBSCURATION CIRCUIT
Setting Operations of the electric signal must be perform according to the following sequence:
8.1 - Switch off the power supply of the detector
8.2 - Rotate the SW3 power selector in one of the positions 1-2-3-4 (fig.9) according to the distance between the detector and the reflector
(FX01-FX02-FX03, etc.) (reference fig.7)
8.3 - Move the jumper of Initial Set JP1 (fig.9) in the position ON (Alignment) to activate the phase of initial setting
8.4 - Power up the detector
8.5 - The blue led and the red one will start to work in the way described ahead in cap. 8.12. Before going on to this chapter read what’s
following
8.6 - the P1 trimmer (regulation of the signal level) is regulated in factory to the 50-60% and it corresponds to a signal of 5V to the maximum
distance
8.7 - 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 EDS 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.8.12
8.8 - If available, connect a 5V fullscale Multimeter between the SIG terminal and the negative power supply terminal 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
8.9 - The detector emits a conic beam which form and dimension, in relation with the distance between detector and FX, are explained in
figures 5 -6. It’s important that the FX is in the center of the transmitter’s conic beam because, under these conditions, even if some small
movements of the wall, on which the detector is mounted, happens (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.
8.10- Regulate the signal to about 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). If this action is not enough, you need to use a smaller reflector or obscure a portion of the
reflector surface in order to reduce the reflective surface. After performing this operation, the adjustment of the trimmer P1 to get the 3V,
becomes simple and non-critical.

EDS - TECHNICAL INSTRUCTIONS
8
8.11 - If the alignment with the Laser pointer was well executed, normally the operation listed below is unnecessary and you can go directly
to step 8.13.
Search for the maximum output signal optimizing the optical alignment of the Transmitter acting slowly and in sequence on the 3 regulation
screws V1-V2-V3 of the optic crew.
This procedure take some time however, if well performed, it assures a perfect work of the detector for many years. We advise to use the
following procedure:
• On the detector slowly turn the screw V1 clockwise and then look at the value of the signal visualized on a Multimeter. If the signal
increased (for example from 3V it rised to 3,5V), then again turn the screw V1 of the detector clockwise and then look at the value of the
signal.
• Continue with this procedure as long as the signal increases. When it has the tendency to decrease instead, stop the operation on the
screws V1 of the detector returning to the previous position.
• If during the operation the signal overcomes 4,5V, to avoid the saturation, act on the trimmer P1 to bring the signal back to 3 V, allowing
the best evaluation of the variations of the signal.
• After finding out the maximum og the signal acting on the screw V1, perform the same operations on the screws V2 and V3.
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.
8.12 - If you don't have a Multimeter, it is still possible to get good results in the optical alignment of the detector, looking at the detector’s
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
• 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.
8.13 - After doing the operations of fine optical alignment using the Multimeter or the indications of the Leds, you must regulate the signal
slowly acting on the trimmer P1, between 4.7V and 4.9V.
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 4.7-4.9V 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.

EDS - TECHNICAL INSTRUCTIONS

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. 8.10.
8.14 - It must be checked out that, since the detector founds its operation on the reflection of the projected beam, this reflection is effected by
the FX reflector only and not from other elements.
To be certain that the signal is produced by the reflection of its FX reflector and not from other elements, it is useful to do a simple verification.
It is necessary to obscure the reflector with a non reflecting screen (opaque).
In that case the signal on SIG terminal must decrease under 0,5V. (check indications in the following pages).
8.15 - Select the alarm threshold level of the circuit sensible to obscuration acting on the selector SW2 keeping in mind the following :
• position 1 - low sensitivity - obscuration alarm threshold set to 70% .........................signal level 1.5V
• position 2 - low to medium sensitivity - obscuration alarm threshold set to 60% .....signal level 2.0V
• position 3 - medium to high sensitivity - obscuration alarm threshold set to 50%.....signal level 2.5V
• position 4 - high sensitivity - obscuration alarm threshold set to 40%...........................signal level 3.0V
8.16 - Sensitivity 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 - SETTING OF THE TURBULENCE CIRCUIT
(not relevant for -S version)
9.1 - The RK100-R 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 performance 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 optical beam smoke 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 has been designed to detect these changes and, when these changes reach the programmed amplitude
and time lenght, 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 detector that has 4 positions (fig.9).
• sensitivity increases from 1 to 4
• position 1 : minimum sensitivity
• position 4 : maximum sensitivity
The 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 endowed with a special circuit of auto-compensation of the signal. If the detector is installed
inside a particularly dusty place, the dust that is deposited on the front surface of the cover causes a drop of the signal. This drawback
is automatically eliminated by the circuit of autocompensation.

EDS - TECHNICAL INSTRUCTIONS
10
11 - FAULT OUTPUT
11.1 - On the terminal block of the detector is available the contact of fault/anomaly relay. This relay is normally excited and will turn not-
excited if the followings conditions are verified:
• the signal goes down under the 90% setting value (optical beam completely interrupted by an obstacle)
• the circuit of autocompensation has reached the limit (when this happens to proceed it is necessary to the maintenance of the detector)
• operation failure (it means breakdown of some component)
Attention: As stated by the relevant standards, 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).
To activate this function operator must insert the JP8 jumper (fig. 9).
Test of this function can be done with a piece of non reflecting material quickly covering the reflector. After around 30 seconds of reflector
covering, the fault output should be activated.
12 - ALARM MEMORY
12.1 - The RK100R(S) is endowed with alarm memory that can be switched ON/OFF through the jumper JP5 (fig.9):
• jumper JP5 in position 1-2 - memory not activated (OFF)
• jumper JP5 in position 2-3 - activated (ON)
When the memory is activated, if the detector goes to alarm, the alarm relay and the frontal red Led remain activated until it doesn't stop
the alarm and is not removed power for over 5 seconds. When the memory is not activated, if the detector goes to alarm, the alarm relay
and the frontal Led are disarmed as soon as it stops the alarm.
12.2 - Memory of the data of configuration and setting.
In case of black out the memory inside preserve the data. To the return of the feeding the detector, later once of initialization of about 2
minutes, returns to normal operation
13 - DETECTOR’S ACTIVATION
13.1 - Put the jumper of initial Set JP1 in position 1-2 (OFF)
13.2 - The blue Led of Alignment flashes in particular way (2 flash slow flashes - 1 break - 2 fast flashes, repeated)
13.3 - Install the cover. The operation of detector’s closing must be done within 5 minutes. The level of the signal will be decreased
because of the absorption caused by the cover
13.4 - The inside electronics attends 5 minutes for the installation of the cover and later performs a rapids procedure (time 1-2 minutes) take
again the signal of the RK100-R to 4,7-5V
13.5 - After this phase of adjustment, the detector becomes operational. The blue Led of Alignment stops (detail cap.10.2) and and it
begins to flash as described in 10.6
13.6 - every 10 seconds the blue Led will emit a short flash that points out the normal operations of the detector. In case of alarm the frontal
red LED turned fixed ON and remains turned ON until it stops the state of alarm or, if it is setted the function of memory, until the supply
is not removed for 5 seconds (v. cap.14)
14 - VERIFICATION OF OPERATION
14.1 - Verification of the sensitive circuit to obscuration..
The verification is carrried out simply by darkening the reflector with an opaque screen. After 10 seconds, detector alarm relay must
activate / not activate (cap.5.2 - jumper JP7) and the alarm frontal red Led must be turned ON. After, remove the screen, the relay of alarm

EDS - TECHNICAL INSTRUCTIONS
11
must be restored and the red Led restarts to flash every 10 seconds. If the function of memorization is activated (cap.14) for the restoration,
it is necessary to remove the eletric power from the detector for 5 seconds.
Attention!
• This test must be effected darkening with a screen the reflector only
• The screen must not be set in front of the detector
14.2 - verification of the sensitive circuit to the Turbulence (if present). Verify of the sensitive circuit to the turbulence putting a non-
reflecting screen in front of the reflector more times with the following sequence (dark / light) and selecting sensitivity through the
selector SW1:
• 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 detector, during the normal operation of the detector, give the following indications (v. fig.9):
• normal operation: the blue Led flashes every 10 seconds
• alarm: the red Led is fixed ON
• limit of compensation, interrupted ray, breakdown: the blue Led flashes
16 - MAINTENANCE
16.1 - The instrument asks for a simple and periodic maintenance. It can be programmed or made automatic on special signaling of the
detector. During the normal operation and after a certain time from the installation, if the maintenance is not performed, the detector,
because of the dirt deposited on the front surface of the cover, produces a Fault signal because of the drop of the signal under the limit of
compensation. Then it will be the moment to proceed to cleaning of the surface so that the initial optical conditions are restablished.
16.2 - The operations to be carried out are the following:
• the detector must not be powered
• clean the cover surface of the detector. You must use a wet cloth with water and some trace of soap. Chemical products like alcohol,
ammonia and similar must not be used . The cleaning of the surface is fundamental for the good detector operation
• verify the inside terminal board tightening the terminals in case they are loose
• verify the optical alignment in case of some deformations of the structure on which the detector is installed. In such case then repeat the
operations of the chap.8
• power up the device
17 - CHANGE THE SENSITIVITY SELECTION
17.1- After the installation and after some operation time, if you want to modify the sensitivity of the detector, read what follows:
• remove the cover (it is not necessary to power down the detector)
• modify the sensitivity acting on the SW2 selector
• close the cover

INTERNAL PARTS
P1 - Trimmer for the signal level regulation 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 circuit sensible to Turbulence (heat). Sensitivity increases from
1 to 4. In position 1, minimum, in 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
SW3 - Selector for the regolation of the transmission power. The power increases from 1 (minimum) to 4 (maximum)
V1-V2-V3 - Scews for the regulation of the optical block
CN4 - Connector for the STS-01 meter (optional)
JP1 - Jumper to activate/deactivate the procedure of optical alignment.
To activate the optical alignment procedure, the JP1 jumper must be on 2-3 position (ON).
To deactivate the optical alignment procedure, JP1 jumper must be on 1-2 position (OFF).
• JP1 position 2-3 (ON)...... alignment procedure activated
• JP1 position 1-2 (OFF)...... alignment procedure deactivated
JP2 - JP3 - JP4 - Jumpers to set the relay contacts, respectively of the alarm relay, turbulence (if present) 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-R-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 autoreset of the detector)
• in position 1-2 memory deactivated. When the alarm state ends the detector resets (Autoreset).
• in position 2-3 memory activated . In case of alarm the detector maintains the alarm state till the power supply is switched
OFF for at least 5 seconds.
JP6 - Jumper for microprocessor Reset (SW reset).
JP7 - Jumper to set alarm relay operation normally activated or deactivated.
• JP7 ON - Alarm relay normally activated (in case of alarm it gets deactivated). In this case the indication of jumper JP2
is inverted.
• JP7 OFF - Alarm relay deactivated (in case of alarm it activates). In this case the indication of the jumper JP2 is correct.
JP8 - Total obscuration fault option- JP8 ON = activated

Example of connection of RK100R-S receiver with a zones control unit.
In this case the detector is a zone of the system.
The state of the indicated relays correspond to the normal operation condition of the detector.
The alarm output is the one of the alarm relay (circuit sensible to obscuration in alarm) or the one from the turbulence relay
(circuit sensible to turbulence (heat) in alarm).
The turbulence relay, if not necessary, can be left unused.
The fault output is the one from the NC contact of the fault relay of RK100R-S.
The values of the resistances of Alarm and End of Line will be indicated by the control unit manufacturer.
