REFLECTIVE TYPE
OPTICAL BEAM SMOKE
DETECTOR
RK100R - RK100RS
GENERAL
The RK100R detector is a newly-conceived microprocessor 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 RK100R 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 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 - RELEV ANT ST ANDARDS
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 RK100R detector we suggest to also use, besides the normal tools (drill, expansion plugs, etc), the following elements:
• 1 - 7mm “C” Key
• 1 - alignment lamp (we recommend to use LAL02 lamp (optional) or an electric torch with powerful and contrated beam)
• 1 - multimeter (we recommend an analogic hand T ester or an analogical STS01 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. W all 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.
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. W e 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 tourbolece (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) - 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. T o use only 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. T o 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 - T o set the output contacts respectively of Alarm relay, Turbulence relay and Fault relay to normally closed NC or normally open NO (cap. 5.1) The RK100R 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)
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 - OPERA TION
6.1 - The RK100R detector is equipped with 2 circuits of detection
of the smoke produced by a fire:
Obscuring - circuit sensitive to the obscuring. 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 - circuit sensitive to the Turbulence. 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 reveal this variation and, when these reach the ampleness and the duration in the time programmed, a signal of alarm is produced. The sensibility 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
7.1 - Proceed with the optical alignment of the detector and FX
reflector. To facilitate the operation we suggest to do it in low ambient light conditions and to proceed in the following way:
• place in front of the reflector FX (fig.3) an optical alignment lamp able to project a concentrated and sufficiently intense light beam. (we recommend the EDS alignment lamp LAL02)
• direct the light beam of the lamp to the lenses of the detector
• look at the screen that is behind the lens, inside the Transmitter (right lens). On it you will see a bright point that represents the image of the lamp
• move the optical block using her special screws V1-V2-V3 with a key, so that the bright point falls in the center where a small hole is present through which the photodiode is visible (fig.4). It’s important that the bright point falls on the photoemitting zone of the photodiode. This zone is represented by the small dark dot in the center of the photodiode (fig.4). In such way the detector will be alligned with the reflector FX. After doing the optical alignment of the detector it is necessary to do the electric signal setting operations, proceding with the following instructions.
8 - SETTING OF THE OBSCURA TION CIRCUIT
Setting Operations of the electric signal must be perform according to the following sequence:
8.1 - Do not power supply the detector
8.2 - Rotate the SW3 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 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 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
8.9 - 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 detector’s conic beam because, under these conditions, even if some small movements of the wall on which the transmitter is mounted on happen (caused by deformations), the reflector remains always within the beam and therefore active.
T o obtain this, the operations of fine centering with output signal measuring, explained below, must be performed with car e.
8.10- Regulate the signal to about 3V acting on the trimmer P1
(fig.9)
8.11 - 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 set on 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 Tester 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 regulation is not critical. The procedure indicated above is the optimal one, but it is enough if the blue Led is flashing or constantly ON to have a good setting. However it is necessary to avoid the saturation (red Led ON). The microprocessor automatically compensates the inaccuracies of the setting.
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. T o 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%
• 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%
8.16 - Sensitivity must be regulated according to the environmental
