WHY IT DOES NOT RESPOND TO THE SUNLIGHT AND LAMPS
Sun and lamps also generate thermal infrared radiation.
But ame is different because it ickers at a particular frequency in the
range from 3 to 30 Hz (pulses per second).
The IR ame detector is tuned to this pulsing radiation like a radio
receiver is tuned to one station and ignores all others.
Nevertheless direct exposition to the sunlight and lamps must be
avoided, since it causes the detector to become blind or give false
alarms.

WHY IR (infrared) RADIATION
The visible radiation emitted by re is just a small amount of the
emitted energy.
The most part is comprised of invisible thermal infrared radiation,
typically emitted by all hot bodies, with a wavelength varying with the
body temperature.

RIV-601P/F
General notions
The IR ame detector model RIV-601P/F is an electronic optical re
detector device that responds immediately to the thermal infrared
radiation emitted by re, and is tuned to the pulse frequency of the
ame to ignore sun, lamps and other light and infrared radiation
sources.
WHY IR (infrared) FLAME DETECTOR
Eye is faster than nose. In the event of live re the IR ame detector
responds immediately. Its behaviour is similar to that of the eye. In
fact it “sees” the radiation emitted by re, and its sensitivity is inside a
cone of 90° which is called the eld of view.
The minimum ame size that can be detected by the RIV-601P/F
varies with the distance. It doubles at double distance and is half at
half distance. The sensitivity value is 2-3% of the distance.
For example, at 10m the smallest detectable ame size is 20-30cm.
At higher temperature a shorter wavelength is generated and
viceversa. The IR ame detector sees very well this IR radiation but is
near blind to the visible light.
Furthermore the thermal infrared radiation passes through the smoke,
while the light does not.
For this reason the IR ame detector responds to the re also when
smoke is present.
Pulse frequencies
FIELD OF VIEW
Flame radiation spectrum

rev. 0 NOV11 MAFP 4-GB
Normally the detector is installed vertically, centred on the area to be
covered, so as the 90° cone eld of view can be fully used. The ideal
height is 0.7 the side of the square area.
For instance, if side is 10m, then height is 7m and maximum viewing
distance is 10m.
If ceiling is lower, corners are the ideal alternative.
In this case the height can be one third of the side.
Direct viewing of sun and bright lamps must be avoided, since this
can blind the detector.
In outdoor applications a small hood or roof will help.
Vibrating or oscillating mounting must be avoided, since this can be a
cause of false alarms.
IR flame detector RIV-601P/FA
with explosion-proof enclosure
Nominal 24Vdc input power is required, with wide span allowed,
and two different outputs are provided: one heavy changeover relay
contact, and one NPN transistor open collector. Both outputs go
into alarm state after a pre-set time delay, but they come back to the
stand-by state as soon as the re stops. The delay time is normally set
to 5 seconds, but can be set in the range from 1 to 10 seconds.
A protection against the 24Vdc power voltage inversion is provided.
Sensitivity is 2-3% of the distance, that means a 10cm ame at 5m
distance, or a 20cm ame at 10m.
The eld of view is a 90°cone, but beyond 90° the detector can see
with reduced sensitivity, and can also see behind obstacles due to
reections.
A small dust build-up over the detector window does not decrease too
much the detector ability, since thermal infrared radiation is little
attenuated by dust, much less than light is. Therefore a frequent
window cleaning is not required.
Also smoke does not blind the detector, which is operating well with
res in heavy smoke.
IR flame detector model RIV-601P/F
with watertight enclosure
DESCRIPTION
The IR ame detector model RIV-601P/F is an electronic optical re
detecting device which responds immediately to the thermal infrared
radiation emitted by re and is tuned to the ickering frequency of the
ame to ignore sun and lamp light.
It is enclosed in a cast aluminium watertight case with IP66 grade
protection, which allows to withstand dusty environment and rain.
An IP66 explosion-proof enclosure is provided for the
RIV-601P/FA model.
It is equipped with the “teletest” device for remote monitoring of
detector.
This device simulates a ame inside the detector so as to stimulate a
sensor response like to a real re.
The teletest device includes an incandescent bulb and a modulator
circuit that generates a pulsating thermal infrared radiation in front of
the sensor.
The teletest can be manually controlled from a remote site, or it can
be automatic and continuously running.
The detector response to the teletest is a short alarm pulse of half a
second every 4 seconds during all the period the teletest is operated.
These short pulses can be recognised by the control panel as a state
of live stand-by, since the real re alarm is continuous. If pulses stop,
this means a detector failure or the power voltage is off.
A front red LED lamp will signal the detector stand-by or alarm state.

MAFP 9-GB
The RIV-601P/F infrared Flame Detector turns on into the alarm state
after a pre-set delay time (waiting time) from the moment a ame is
started and is seen inside the 90° eld of view.
As soon as the ame stops, the detector returns back to the stand-by
state.
If the ame duration is less than the delay time, then the detector
never reaches the alarm state and the time count is reset to zero.
The delay time is set to 5 sec. during production. It can be adjusted
within the setting range of 1 to 10 sec. by the customer during the
installation by turning the one-turn screwdriver potentiometer.
The detector eld of view is a 90° cone, starting at the optical window
centre.
Outside the eld of view the detector sensitivity is lower but not zero,
due to reection from walls and objects. For the same reason the
detector can see behind obstacles.
This ame detector can be used for all the applications, indoors and
outdoors, where there is a high risk of fast spreading re (fuels,
ammable liquids, etc.), and an immediate alarm is required.

Mounting information
The waterproof model RIV-601P/F can be installed without any
bracket by means of four screws.
The explosion-proof model RIV-601P/FA is made by mounting the
model RIV-601P/F inside the explosion-proof enclosure model
ADF-600AP. It will be installed on the requested position using the four
screws included in the package.
 - Vertical application with FULL area coverage.
The detector must be installed over the area to be monitored, looking
down vertically on the centre, at a height that is 0.7 times the side of
the area (square).
For example, from a height of 10 m a oor area of 14x14m can be
controlled.
This sort of installation uses the full detector eld of view, that is the
best one.
All oor area is covered.
Since the detector sensitivity is 2% of the distance (4% for the
explosion-proof model), the smallest detectable ame size is 20cm at
the centre where the distance is 10m, and 28cm at the corner where
the distance is 14m.

- Vertical application with PARTIAL area coverage
When ceiling is low or not high enough for full coverage, the
centre vertical mounting is anyway used, provided only small
corner areas are out of the detector eld of view, and these
small areas are not under risk of re.
For example, a room 10m high with a oor of 16x20m is almost
completely under the detector eld of view. Only four small
areas on the corners are out.
The smallest detectable ame size is 20 cm on the centre (2%
of 10m distance) and 28cm on the border (2% of 14m
distance).
The limit of this application could be a room 10m high with a
oor of 20x20m, where the cone eld of view base circle
touches the oor sides. In this case the side length is 2 times
as much as the ceiling height, and the smallest detectable
ame size is 28cm in the worst case (2% of 14m distance).

 - Diagonal application with FULL area coverage
When ceiling is too low for full area coverage with centre vertical
mounting, and only one detector is preferred, then the detector can
be mounted on a ceiling corner so as it looks diagonally down 45°
towards the oor.
For example, a room 10m high with a oor of 16x20m is fully under
the detector eld of view.
The smallest detectable ame size is 20cm under the detector corner
(2% of 10m distance) and 55cm on the most distant oor corner 2%
of 27.5m distance).
As you see, the smallest ame on the opposite corner is more than
two times as much as under the detector corner. This disadvantage
must be considered when choosing this type of application.
Also, the diagonal mounting makes the detector seeing other strong
infrared lights entering into its eld of view, like lamps and sun, which
can cause false alarms. It is recommended to properly choose the
detector position in order to avoid false alarms.
The limit of this application could be a room 10m high with a oor of
30x30m. In this case the side length is 3 times as much as the ceiling
height, and the smallest detectable ame size is 80cm in the worst
case (2% of 40m distance).

 - Vertical application of two detectors with FULL area
coverage
When a room cannot be under the eld of view of one detector, then
the room can be divided into two detection areas, each of them being
monitored by one detector mounted vertically on the centre of each
area.
This type of application is the double of the “A” type described above,
and has a better performance than the “C” type of the previous page.
In the case of a room 10 m high with a oor of 14x28 m the smallest
detectable ame size is 20cm on each area centre (2% of 10m
distance) and 28cm on each area corner (2% of 14m distance).
The limit of this application could be a room 10m high with a oor of
20x40m, which has eight small areas on the eight oor corners not
fully under the detectors eld of view.

 - Diagonal application of two detectors with FULL area
coverage
In this example of application two detectors are mounted diagonally
and perform the monitoring of a big room with both full area coverage
and a partial common area for a double checking.
In the rst case the room is 10m high and has a oor of 20x40m.
In the second case the room is the same but the two detectors are
mounted in a slightly different position.
The disadvantages of the diagonal mounting must be considered

 - Vertical application over pole with FULL area coverage
For outdoor applications the rules to be followed are the same as the
ones for indoor or room applications. The detector must be mounted
vertically looking down.
The elements to be considered are the area surface to be monitored,
the height of the pole available, the smallest ame size needed to be
detected with 2% detector sensitivity (the smallest ame size is 2% of
the distance) and 90° cone eld of view.
The oor area diameter is two times as much as the height, and the
distance of the oor circle is 1,4 times as much as the height itself.
Also, in outdoor applications a roof or cap or an equivalent
mechanical protection must be provided in order to prevent both rain
or snow to build up over the detector enclosure and to prevent as
well the detector from seeing directly the sun or other strong lamps
present around, so as to avoid false alarms.
In the case sensitivity is too high for the application, one or more
attenuation optical lter can be added on the front of the optical
window. These lters can be delivered on demand, free (see page
MAFP 19)
Caution must also be taken to design a strong and rigid support to
avoid oscillations and vibrations under mechanical shocks and wind
pressure.
One practical example is a oor area of 40m in diameter and a 20m
high pole.
In this case the smallest detectable ame size is 40cm on the centre
(2% of 20m height), and 56cm on the circle (2% of the 28m distance).

IR flame detector electrical connections
The electrical connections are done on 7-way screw type terminal
block, plug in type.
Each terminal function is printed on the top of every terminal and on
the circuit board just before the connector.
The input power voltage is 24Vdc nominal value, with an accepted
range of 20 to 28Vdc.
The current values are rather low, typically 0.1 to 0.2 Adc. Therefore
the wire gauge is only chosen to be strong enough, not for the rated
current.
A max 1,5 square mm wire gauge is suggested to avoid a difcult wire
entry into the screw terminal.
Before turning the input power on is highly recommended to check the
power voltage value and polarity in order to avoid damage.
Input power:
The 24Vdc power voltage must be entered into the two terminals
marked ( +) and ( -). Pay attention to the polarity, even if an
anti-inversion diode is provided on the ( +) terminal.
Please remember that after the 24Vdc power voltage is applied the
detector is disabled and standing by for about 10 seconds (start-up
delay) before starting the normal operation and being able to start an
alarm.
Output:
• One static output on the “S” terminal from an NPN collector.
Normally it is high (+24V). In alarm goes low (+0.1V or higher,
depending on the load). Max load 50mA to +24V.
• One changeover SPDT relay contact on the C-R-L terminals, rated
1A 30Vdc.
C-R normally closed contact. Opens in alarm.
C-L normally open contact. Closes in alarm.
Test:
The T +must be connected to +24V through a normally open
pushbutton, which will be depressed for more than 5 sec in order to
perform the manual test (see the next page).
The T +terminal must be permanently connected to +24V if the
automatic continuous self test is wanted (see the next page).

The test function makes it possible to remotely monitor the full
detector operation both if in alarm state or if faulty. This function is
performed by powering a small incandescent bulb placed near the
infrared sensor inside the detector. The bulb light is made pulsing by a
built-in modulator circuit, in order to simulate a real ame.
If the test is held on for more than 5 seconds, then the detector goes
into the alarm state just for a small time of 0.5 seconds, then it restarts
the waiting cycle of 5 seconds. During all the time the test is on, the
detector outputs a small alarm pulse of 0.5 second every 5 seconds.
During this test pulse The front LED lamp is lighted for 0.5 seconds,
the Sterminal goes low for 0.5 seconds, and the relay contact too
is activated for 0.5 seconds, i.e., the normally closed contact (C-R)
opens for 0.5 seconds, and the normally open contact (C-L) closes for
0.5 seconds. If the detector is faulty, it does not respond to the test
function, and no test pulse is generated. Therefore the test pulses do
mean the detector is healthy, instead the absence of test pulses do
mean the detector is faulty.
Please remember that this internal test does not allow to check the
detector optical window integrity from a dust or dirt build-up but only
the electronic circuit operation. Then if the optical window is dirty, the
sensitivity is reduced, and the re could not be detected, even if the
test is ok. Anywhere, a small dust or dirt amount does not make the
detector blind.
To externally check the detector, a cigarette lighter could be lighted in
front of the detector, but it must be waived in order to create a real re
ame. For an automatic optical window integrity checking, the
optional LAM-612 unit could be used, which will generate the test
pulsing light from an external position to the detector window.
Manual test
The T+ terminal is connected to +24V through a normally open test
pushbutton. Hold the push button on for at least 10-20 seconds.
After 5 seconds the detector gives a short 0.5 seconds alarm pulse,
then restarts and waits another 5 seconds to give a second
0.5 seconds pulse, etc., for as long as the pushbutton is held closed.
As soon as the pushbutton returns open the test cycle is reset.
During the manual test the alarm panel must disable all alarm outputs,
or it must be able to recognise the short pulses only as a healthy
detector state, since the re alarm state is longer, at least 5 seconds.
Automatic test
The T+ terminal is wired to (+) terminal (+24 V).
After the 5 seconds initial delay time the test pulses cycles are started.
One 0.5 seconds alarm pulse is given every 5 seconds time period.
In this case the alarm panel must be able to recognise the short
pulses only as a healthy detector state, since the re alarm state lasts
longer, at least 5 seconds, in order to provide a fault warning signal if
the test pulses are discontinued.
With a standard alarm panel which cannot be programmed to
recognise the test pulses, a more standard solution is suggested, as
described in the following page, in which the test is used to cause a
line short circuit fault warning signal.

rev. 0 NOV11 MAFP 18-GB
Electrical connections to a standard fire alarm
panel
Both the normally open (C-L) and the normally closed (C-R) relay
contacts are used.
The normally open contact (C-L) is used for the re alarm and
provides the line current determined from the R1 and R2 resistors
parallel.
The normally closed contact (C-R) is used for the fault warning signal
(detector always OFF or 24Vdc power voltage OFF).
Since during the automatic test the detector generates a short 0.5
seconds pulse every 5 seconds (C-L closes for 0.5 seconds and C-R
opens for 0.5 seconds) the L1 line must be delayed for at least 5-10
seconds before giving a re alarm signal when C-L closes.
The fault warning signal must be delayed for at least 10-20 seconds
before the C-R closure can be considered a fault.
Every 5 seconds the C-R contact opens for 0.5 seconds, and the
delay time is reset.
Note:
The two standard fault warning signals are still available:
- open line fault
- short circuit line fault

Sometimes the presence of strong noise, coming from sun or
incandescent lights modulated by moving trees or other things, that
cannot be avoided by changing the detector position, needs to
decrease the detector sensitivity in order to avoid false alarms.
For this purpose one or more attenuation optical lters are provided,
which do reduce the detector sensitivity.
These optical lters are yellow adhesive plastic (poly-carbonate) discs,
39mm in diameter and 0.25mm thick, that can be placed externally
over the optical window.
The sensitivity reduction prevents the detector from issuing false
alarms, still assuring a good sensitivity level.
One lter disc decreases the detector sensitivity from the standard
value of 2% to 3%.
Then the smallest detectable ame size becomes 3% of the distance.
This means that at a 10m distance the smallest detectable ame size
is increased from 20cm to 30cm.
With two lter discs the sensitivity becomes 4% of the distance, that
is, at a 10m distance the smallest detectable ame size is 40cm.
With three lter discs the sensitivity becomes 6%, that is, at a 10m
distance the smallest detectable ame size is 60cm.
When needed, usually only one lter disc is used. The use of more
than three lter discs is wrong.
