Installation TIPS for fogging s stems – RECOMMENDATION 4.
Please observe t e following instructions for installing Orion Tec nology:
1. T e mac ine must be installed avoiding obstructing escape routes.
2. Verify t e fog does not limit t e visibility near: stairs, landings, moving objects t at may cause:
falls down, injuries or any damage to persons.
3. Do not look directly into t e nozzle. Do not add any ot er substance into t e bags.
4. T e nozzle may reac ig temperatures, touc it may cause burns.
5. W en Orion Tec nology produces fog avoid staying closer t an 1 meter from t e mac ine.
6. W en Orion Tec nology is armed avoid staying closer t an 50 cm from t e nozzle.
7. Before testing Orion Tec nology, remember to report it in advance to t e firefig ters in your area
to avoid false alarms.
8. Remember to put warning labels about t e presence of Orion Tec nology on t e windows.
9. Report its installation to t e firefig ters in your area and eventually to ot er institutions if needed.
10. It is necessary to add an external switc to separate t e fog generator from t e alarm system and it
s ould be activated before t e maintenance to avoid t at input tests, for example, can activate t e
fog generator.
11. Never direct t e fog jet towards an object or a wall less t an 2 meters away and if possible increase
t e suggested minimum distance. T anks to t e power of t e jet, Orion Tec nology reac es and
exceeds more t an 10 meters away in t e first 3 seconds from t e point w ere t e mac ine is
installed.
12. Setting t e s ooting time interval between t e minimum and maximum s own in t e s ooting
table, avoid “overs ooting” even if t e produced fog is dry and generally doesn’t leave residue. A
s ot t at goes far beyond t e recommended seconds can create a residue problem in t e room.
13. Orion Tec nology continues to be effective for up to 2 ours wit out 220V main power t anks to
t e insulation system w ic maintains t e temperature in t e eating system.
14. Install at a eig t of about 2.5 meters not to let it be reac ed, avoiding possible tampering.
15. Install wit a maximum inclination of 20°.
16. Do not move t e mac ine w en it is still ot.
17. T e main body of Orion Tec nology, w ic as t e eating system enclosed inside a metal frame,
s ould not be opened unless by specific and aut orized service centers. Do not open and touc for
any reason t e insulation before 24 ours Orion Tec nology as been s ut off. T e internal part
may reac really ig temperature.
18. Do not activate t e Orion Tec nology mac ine before t e installation is completed.
19. Insert t e bags as t e last procedure and verify t e anti-tampering function.
20. W en t e installation is finis ed, always test t e system.
21. From t e moment of Orion Tec nology activation, at least one our is necessary to reac t e
minimum temperature needed for t e fog s ooting.
22. Install Orion Tec nology avoiding any obstacles in front of it w ic can prevent t e spreading of t e
fog.
23. T e external temperature of Orion Tec nology can c ange from room temperature to 50 °C.
24. T e tip of a stranded conductor s ould not be soft-soldered w ere t e conductor is subjected to
contact pressure.

T e “empty” signal doesn’t mean only t at t e bag is empty, but also warns you t at t e
system as s ot at least 100 seconds.
For t is reason is very important to make t e “reset” only w en you really exc ange t e bag,
or you will lose t e seconds counting. (See paragrap 14)
How to Activate the S stem 6.
It is always recommended to fix t e fog generator to a wall even w en it is placed on a flat
surface. T e optional bracket, mainly recommended for ceiling installation, can also simplify
standard installation, by allowing to use back oles for t e passage of cables. Remember to
use t e fixing screw placed in t e bag compartment.
Always verify t at t e bracket or t e support surface are suitable for t e weig t of t e mac ine.
It is suggested not to install t e mac ine be ind walls in a limited closed area wit out a specific ventilation,
in order to prevent a possible over eating.
CAUTION: to avoid injuries please securely fix t e fogging mac ine to t e wall according to t e installation
instructions. In case of installation be ind a wall, it is possible to request a nozzle extension, (7 cm).
After removing t e mac ine from t e package, unscrew t e two screws t at stop t e rig t side panel and
remove it. Remove tamper screw and s ell screws from inside.
At t is point it is possible to remove frontal s ell and see electronic circuit, from ere on called PCB.
To open t e additional compartment in t e lower part, it is necessary to remove bag compartment’s door
and take off t e frontal s ell, unscrew and remove t e screws below.
T e screw in lower left part of bag compartment’s door is longer t an t e ot ers and its removal activates
t e tamper output.

T e screw in lower left part of bag compartment’s door is longer t an t e ot ers and its removal activates
t e tamper output. After t e screw as been positioned correctly, t e mac ine emits 4 beeps and
deactivates tamper output.
Main Power suppl 7.
220V-230VAC power source supplies energy only to t e eating system. T e electronic board and t e bag’s
pump are supplied from t e alarm system and batteries. T e eating element is of 0,3KW, at t e very
beginning power consumption is about 250W and in some minutes it goes down reac ing average
consumption is about 40W - 60W.
Do not use inverter or UPS if you are not sure t at t ey generate a true sine wave, not a rebuilt
one. Ask please to t e UPS manufacturer t e correspondence of suc features before
proceeding wit t e connection.

Description of input and output connections 9.
INPUTS 9.1.
+ 12V Power input 9.1.1.
In t ese inputs is necessary to provide a stable supply, between 11V and 14V DC from t e alarm control
panel or from an external 12V power supply. T is power is necessary to t e operation of t e LED. T e
eating system c ecking and t e battery rec arge, t e logic part.
In absence of voltage on t is input, t e logic part will continue to operate, but eating system and LEDS
(except for t e BLUE one, arm) will stop working. Until w en t e eating system allows (about 2.30 ) t e
mac ine may emit fog.
After t at time t e PCB will switc off automatically.

INPUT SIGNALS 9.1.2.
A By connecting t is input to positive, FOGGING SYSTEM is armed, blue frontal LED is switc ed on and
w en t e mac ine reac es proper temperature it means t at it is ready for s ooting.
In case of alarm, opening ARM input, t e fog emission stops immediately, even if t e time set wasn’t
reac ed.
S Putting t is input to positive, if FOGGING SYSTEM is ot and armed, starts fog emission for t e set time
(see paragrap 12).
VALIDATION INPUT
9.1.3.
In order to validate t is input, it’s necessary to insert t e jumper W4. T is input automatically generates
AND function wit input S.
If any input receives t e s ooting command, t e generator doesn’t emit fog if wit in 1 minute doesn’t
receive t e command also from t e second input.
P+ Output positive to give power to a validation sensor or a remote control receiver, max 300 mA.
P- Output negative to give power to a validation sensor or a remote control receiver, max 300 mA.
PV Validation input. It’s possible to connect to t is input a validation sensor wit a contact normally closed
connected to t e terminal P-.
In order to c eck t e correct operation of PV input, it’s necessary to remove t e jumper W4.
W en AND function is disabled, to eac opening of PV input you will ear a “beep” for 5’’. At t e end of t e
test, re-establis AND function inserting jumper W4 again
OUTPUTS 9.2.
E T is output (NPN Open Collector) closes towards negative direction w en t e bag is empty. T is output
(NPN open collector) closes towards negative w en t e fogging mac ine emitted fog for at least 100’’ or
w en t e bag is empty. T e signal is activated by a sensor t at detects t e absence of liquid just w ile
s ooting.
T e empty bag signal is deactivated only making t e RESET (see paragrap 14). For t is reasons, if t e bag is
not inserted, or t ere is an empty bag inside, FOGGING SYSTEM will detect it just after a s ot.
F T is output (NPN Open Collector) closes towards negative w en t ere is a malfunction (suc as batteries
expired, fault of power supply or temperature control fault), w ic compromises t e functioning of t e
device and w ic requires a tec nical action.
T T is output (NPN Open Collector) closes towards negative direction w en you open t e bag door or
w en t e accelerometer detects a sudden movement (suc as t e detac ment from t e wall).
C T is output (NPN open collector) closes towards negative only after t at t e system as emitted fog for
t e set time. If t e emission of fog is interrupted (if t ere is an interruption of ARM command, if t e glycol
finis es, if t ere is not t ermal autonomy anymore) t is output will not c ange its status.
Remember, it is necessary to connect all t ree outputs to an alarm central or an electronic
panel t at can see all t ose information in real time and take proper action.
In order to avoid accidental activation wit subsequent fog emission, t e inputs are in
“negative security”, for t is reason t e disconnection of a wire does not cause activation.
So it is necessary to c eck carefully t e reliability of connections and protect t e cables to t e control panel
to avoid t e risk of accidental damages.

Shooting time setting and fog Flow direction. 12.
To set t e s ooting time, after opening t e cylinders compartment door, at t e
top of t e PCB, facing t e board you must move t e jumper in left position P3
(closer to t e buttons S1/S2). T en, olding down t e button S1 “SET”, 6 LEDs on
t e front will flas and eac flas is equivalent to one second.
If you press t e button again, t e s ooting time is not added to t e one previously
set, but will restart from zero.
N.B. Before opening side door ensure that the control panel is set to “service”, so that the opening of
“anti-sabotage or tamper” circuit does not cause an shooting
T ere mig t be cases in w ic , due to specific c aracteristic of t e location, nozzle type, levels of
temperature and air pressure, degree of t e fog density and lig t in t e target area, t e s ooting time can
be increased or decreased accordingly by referring to t e following formula:
(HxLxP) x D x V x I
HxLxP--------Height x Width x Depth of the area to protect
D-------------Densit of the produced fog
V-------------Temperature and air pressure
R-------------Acceptable residue in case of saturation of V parameter
I--------------Intensit of the surface light
The following guide indicate the suggested fog emission in relation to the number of seconds of shooting
set in average condition of temperature, air pressure and humidit .
So these are the details for the OT-U250PP:
Max. Shooting time per single Shoot: 30 seconds shooting speed: 8.5 cubic meters per second
Bag Low fluid signal after 100 seconds (average)
Total Bag shooting capacit : 116 seconds equivalent to 1500 cubic meters

T e first value indicates in m³ t e area to protect, t e second one indicates t e seconds of emission. T e
value in m³ may vary depending on t e density t at you desire to obtain. Considering t e first value you
obtain a density t at guarantees a visibility of zero meters. Wit t e second value you obtain a density t at
guarantees a visibility of 1.5 meters. Naturally, in places w ere a slig t residue is not a problem, it is
possible to increase t e time of s ooting. We remind you t at more fog is released more time it takes to
ave visibility again. Hig er levels of fog over suggested limits may fill t e room and leave a residue.
Any residue usually goes away by itself wit in 24/48 ours, ot erwise, being soluble in water, it is enoug
to use a wet clot for cleaning.
If you desire to obtain an average of 1 meter visibility after 60 seconds, as specified by t e standard, as
used as reference by all manufacturers of Fog generators, t e number of s ooting seconds must be
doubled.
FOG FLOW DIRECTION 12.1.
To ensure t e rig t direction of t e fog flow, it is recommended to insert a
screwdriver of t e diameter of t e ole and, wit out forcing, orient t e nozzle in
t e correct fog emission direction. T is allows you to clearly see t e direction and
keep it in place w ile tig tening. To screw and unscrew t e nozzle you s ould use
a pair of pliers in good condition to avoid damaging t e plating. Do not over screw
t e nozzle; it is sufficient t at t e Teflon nozzle does not move.
Do not direct t e fog jet towards objects and walls less t an 2 meters away or to
t e floor if it is installed at a eig t lower t an 2.50 meters (we advise against t e
installation on t e floor).
WARNING! After t e fog emission and for a few minutes t e nozzle is very ot RISK OF BURNS IF
TOUCHED by bare ands.

Nozzle Tamper 13.
T e c eck of t e obstruction of t e nozzle is done wit a little air flow, w ile a sensor c eck t e pressure of
t e internal circuit.
In case t e sensor detects an increase of t e internal pressure, means t at t ere is an obstruction inside
t e nozzle.
In t e meantime, t e output of Tamper will be activated; t e buzzer will emit a sound wit a fast frequency
wit t e flas of t e red LEDs.
T is condition of t e alarm will continue until t e system is disarmed and armed again.
As t e little compressor t at introduces t e air flow emits some vibrations, its activation occurs only in t e
following cases:
•W en you press t e button RESET for more t an 5 seconds, besides t e activations of t e drop of
t e motors, will start a cycle of monitoring of 15 minutes, in order to simulate t e obstruction and
c eck t e correct working.
•W en t e system is armed t e cycle of monitoring starts. T is cycle is t e most important, because
as t e system was disarmed probably was easier to go near t e mac ine and obstruct t e nozzle.
After 15 minutes, t e compressor will stop automatically. If t e system is disarmed and armed
again, t e cycle will start again for 15 minutes.
•After t e emission of t e fog, as normally t e zone w ere t e mac ine is installed is t e last w ere
t e visibility is reduced, t e generator remains vulnerable, giving t e possibility to w o generated
t e alarm to attempt t e sabotage. For t is reason, after t e emission of t e fog t e compressor
will be activated for 15 minutes.
Do not obstruct the nozzle when the generator is armed and bag is in.
Installation, Exchange and Bag reset 14.
After removing t e screws of t e door, is sufficient to remove t e bag and reset t e
LED of empty bag.
In order to make t e reset t e jumper P3 must be
on t e rig t position as you can see in t e picture.
After t at, insert a new bag until you ear t e “click” of t e plastic support entering in its ousing, t en
close t e door.
N.B. When ou close the door, the buzzer will make a sound to confirm the tamper is closed.
Attention: Before opening the side doors, make sure that the alarm control panel is in
“service” mode, so that the opening of the “anti-sabotage or tamper” circuit does not cause
an alarm

Maintenance 15.
Orion generators do not require special care owever, it is recommended t e support of qualified and
aut orized personnel for periodic annual monitoring, taking into account t e following:
•Annually verify t e functioning of t e pump.
•C eck t e air tig tness of t e circuit and t e switc functioning.
•T e efficiency of t e batteries is crucial to guarantee t e operation
CHECKING OF THE PNEUMATIC CIRCUIT AND THE PRESSURE CONTROL SYSTEM
THE TEST CAN BE DONE JUST BY QUALIFIED PERSONNEL
Before starting t e test of t e pressure control it’s necessary:
•to remove t e bag
•to be sure t at t e nozzle is cold
•to be sure t at t e nozzle tamper pump is activated
T e pneumatic seal test must be done wit in a few seconds w en t e pump for nozzle tamper control is
turned on, as t e nozzle temperature rises rapidly reac ing temperatures t at may cause serious burns.
The air coming out of the nozzle exceeds 200° C.
IT’S ADVISABLE TO USE GLOWES
1. Obstruct t e nozzle wit soft and insulating material (for example an eraser).
2. Keep t e nozzle obstructed, press t e button P3 previously moved in RESET position (see paragrap
14) and keep it pressed until you ear t at t e pump is activated.
3. Wait 30’’ for t e activation of t e buzzer.
4. Remove t e obstruction taking away your and quickly to avoid being in contact wit t e ot
emission of air.
T e buzzer must stop.
•If t ere is any loss inside t e pressure circuit, wit in 30’’ t e buzzer will be activated.
•If after 30’’ you don’t ear t e buzzer, may be a loss inside t e circuit; please contact t e service
center.
•If after removing t e obstruction t e buzzer doesn’t stop, it means t at t ere is an obstruction;
please contact t e service center.

Reset from Fault condition 16.
T is process is useful to discriminate false interpretations of faults caused by electrical s ocks or serious
problems on power supply from t ermal loop problems.
1. Serious fault signal occurs wit a first p ase w en t e buzzer emits a continuous sound for 20
minutes and blue led flas es, t e output FAULT immediately switc (if t e generator is
disconnected and connected again you can go directly at point 3)
2. After 20 minutes, t e buzzer stops, w ile blue led goes on flas ing, t e FAULT output remains
closed. T is p ase remains permanently, until t e mac ine is completely disarmed.
3. W en you connect again t e mac ine, blue and red LEDs flas alternately and no sound is emitted.
T is p ase lasts for 30 minutes, t en, t e output FAULT is reset and t e generator start to work
again. If during t is process t e generator is disconnected, w en you connect it again t e time start
again from t e beginning and for 30 minutes.
If at t e end of t is process, t e generator start to work again regularly is not necessary any furt er
operation.
If occurs again t e fault condition wit in t e following 20 minutes, it’s necessary a c eck from t e
assistance center, or to send t e mac ine back to t e factory.

DEFECT FOUND
POSSIBLE CAUSE
POSSIBLE SOLUTION
W en you arm t e mac ine
you ear an internal buzz, like
a motor
T e compressor is c ecking t at
t ere are no obstructions in t e
circuit of fog emission
W en t e mac ine is armed, for 15
minutes t e compressor will monitor t e
nozzle. After t is time it will deactivate
automatically: if t e fogging system is
disarmed, t e compressor will go on wit
it reac es 15 minutes.
If t e mac ine is disarmed and t en armed
again, t e count will start again from zero.
W en you arm t e fogging
system, a little fog flow goes
out from t e nozzle even if t e
mac ine as never s ot
before
During testing p ase in t e
factory, we also test t e quality
of fog in all produced systems, a
little quantity of t e fog liquid
remains in t e ducts
T is emission occurs just at first activation,
it will decrease visibly wit any activation,
until disappearing completely.
After an eventual disassembly and
reinstallation or after t e transport of t e
mac ine, wit t e first activations a little
flow of fog can occur again.
