Introduction of the Product

2.

Thank you for purchasing Orion Technology product.
The great patented technological innovations such as the liquid injection system, the fact with the heating
system, all of them make the FAST fog generators the best fog devices with the best performance in the
security market.

- Simple: Easy to install machines
Can be integrated to any existing alarm system

Conditions of use and Warnings

3.

The fog generated by Orion Technology does not create particular problems or injuries for a human being
for a short stay in a fogged room if the system is used according to the manufacturer’s recommendations.
Generated fog is certified as safe for people and animals from an authorized international certification
company and is proved that it does not leave any residual. The systems are certified respecting European
laws and regulations. Any certifications required in specific countries are a responsibility of the distributor
of that specific country.
The documents related to certifications can be requested by mail to [e-mail]. It is not
guaranteed by the manufacturer the use of Orion Technology system in the presence of objects that may
be damaged anyway by the contact with substances based on glycol, water and alcohol. Any employee or
worker that may be exposed to fog must be warned in advance and must be checked for any allergy to the
substances listed above. At the date of printing of this manual it has never been pointed out any problem
related to any allergy. Orion Technology is in no way responsible for any damage or condition of use that
has not been required and specifically approved by any specific written request prior to the installation of
its products. For fog fluid please refer to Orion Technology fluid safety data sheet published on the website
and carefully read it at www.Orion-technology.eu. Contact a doctor if for any reason you swallow fog fluid
or if after contact with eyes or skin you have any kind of reaction, and in any case wash it immediately with
water and soap. Do never stay for a long time in a room filled with fog. Do not use charged bags that are
not the ones suggested by Orion Technology and never try to recharge them, they are made for a single
use. Follow your national rules for the dispose of empty bags. Keep Orion Technology bags out of reach of
babies and animals. The nozzle may be hot and touching it may cause burns. Do not look directly into the
nozzle. Never use Orion Technology products for any purpose that is not related to protection from thief or
robbery (the choice of the conditions of use in case of robbery will be suggested by your security
consultant).
Never use different fog fluids or add any other substance into the bags. Do not use or keep charged Orion
Technology machines in vehicles and do never transport Orion Technology before 24 hours since it has
been shut off. During transport it must be not armed.

Installation TIPS for fogging systems – RECOMMENDATION

4.

Please observe the following instructions for installing Orion Technology:

1. The machine must be installed avoiding obstructing escape routes.

2. Verify the fog does not limit the visibility near: stairs, landings, moving objects that may cause:

falls down, injuries or any damage to persons.

3. Do not look directly into the nozzle. Do not add any other substance into the bags.

4. The nozzle may reach high temperatures, touch it may cause burns.

5. When Orion Technology produces fog avoid staying closer than 1 meter from the machine.

6. When Orion Technology is armed avoid staying closer than 50 cm from the nozzle.

7. Before testing Orion Technology, remember to report it in advance to the firefighters in your area

to avoid false alarms.

8. Remember to put warning labels about the presence of Orion Technology on the windows.

9. Report its installation to the firefighters in your area and eventually to other institutions if needed.

10. It is necessary to add an external switch to separate the fog generator from the alarm system and it

should be activated before the maintenance to avoid that input tests, for example, can activate the
fog generator.

11. Never direct the fog jet towards an object or a wall less than 2 meters away and if possible increase

the suggested minimum distance. Thanks to the power of the jet, Orion Technology reaches and
exceeds more than 10 meters away in the first 3 seconds from the point where the machine is
installed.

12. Setting the shooting time interval between the minimum and maximum shown in the shooting

table, avoid “overshooting” even if the produced fog is dry and generally doesn’t leave residue. A
shot that goes far beyond the recommended seconds can create a residue problem in the room.

13. Orion Technology continues to be effective for up to 2 hours without 220V main power thanks to

the insulation system which maintains the temperature in the heating system.

14. Install at a height of about 2.5 meters not to let it be reached, avoiding possible tampering.

15. Install with a maximum inclination of 20°.

16. Do not move the machine when it is still hot.

17. The main body of Orion Technology, which has the heating system enclosed inside a metal frame,

should not be opened unless by specific and authorized service centers. Do not open and touch for
any reason the insulation before 24 hours Orion Technology has been shut off. The internal part
may reach really high temperature.

18. Do not activate the Orion Technology machine before the installation is completed.

19. Insert the bags as the last procedure and verify the anti-tampering function.

20. When the installation is finished, always test the system.

21. From the moment of Orion Technology activation, at least one hour is necessary to reach the

minimum temperature needed for the fog shooting.

22. Install Orion Technology avoiding any obstacles in front of it which can prevent the spreading of the

fog.

23. The external temperature of Orion Technology can change from room temperature to 50 °C.

24. The tip of a stranded conductor should not be soft-soldered where the conductor is subjected to

contact pressure.

25. The Orion Technology machine should not be exposed to water spray or dripping.

26. Request to Orion Technology or its distributors to take part in courses for installers to ensure the

optimal installation of the equipment.

The “empty” signal doesn’t mean only that the bag is empty, but also warns you that the
system has shot at least 100 seconds.
For this reason is very important to make the “reset” only when you really exchange the bag,
or you will lose the seconds counting. (See paragraph 14)

How to Activate the System

6.

It is always recommended to fix the fog generator to a wall even when it is placed on a flat
surface. The optional bracket, mainly recommended for ceiling installation, can also simplify
standard installation, by allowing to use back holes for the passage of cables. Remember to

use the fixing screw placed in the bag compartment.
Always verify that the bracket or the support surface are suitable for the weight of the machine.
It is suggested not to install the machine behind walls in a limited closed area without a specific ventilation,
in order to prevent a possible overheating.
CAUTION: to avoid injuries please securely fix the fogging machine to the wall according to the installation
instructions. In case of installation behind a wall, it is possible to request a nozzle extension, (7 cm).

After removing the machine from the package, unscrew the two screws that stop the right side panel and
remove it. Remove tamper screw and shell screws from inside.
At this point it is possible to remove frontal shell and see electronic circuit, from here on called PCB.

To open the additional compartment in the lower part, it is necessary to remove bag compartment’s door
and take off the frontal shell, unscrew and remove the screws below.
The screw in lower left part of bag compartment’s door is longer than the others and its removal activates
the tamper output.

- 6 -

Installation and use manual for OT-U250PP & OT-U500PP

The screw in lower left part of bag compartment’s door is longer than the others and its removal activates
the tamper output. After the screw has been positioned correctly, the machine emits 4 beeps and
deactivates tamper output.

Main Power supply

7.

220V-230VAC power source supplies energy only to the heating system. The electronic board and the bag’s
pump are supplied from the alarm system and batteries. The heating element is of 0,3KW, at the very
beginning power consumption is about 250W and in some minutes it goes down reaching average
consumption is about 40W - 60W.

Do not use inverter or UPS if you are not sure that they generate a true sine wave, not a rebuilt
one. Ask please to the UPS manufacturer the correspondence of such features before
proceeding with the connection.

• The max current to be considered for the system is 4A

• The connection to the 230V electricity grid must be performed by a qualified technician.

• Connect the equipment to the electricity grid only after you have completed the installation.

• It is necessary to connect the ground terminal.

• The system must be connected to the mains trough on automatic switch:

(automatic switch, curie C, with Ih= 10 A and Idif= 30 mA,...) with breeching capacity based on the
assumed fault current of the fogging system in the sampling point.

PLEASE NOTE THAT, AS ALL POWERED EQUIPMENT FROM THE ELECTRICITY GRID REQUIRING
INSTALLATION, IT IS SUBJECT TO COMPLIANCE WITH RULES OF THE COUNTRY IN WHICH IT IS INSTALLED
For section and types of wires, fuses, suitability of materials to installation sites etc..

Description of input and output connections

9.

INPUTS

9.1.

+ 12V Power input

9.1.1.
In these inputs is necessary to provide a stable supply, between 11V and 14V DC from the alarm control

panel or from an external 12V power supply. This power is necessary to the operation of the LED. The
heating system checking and the battery recharge, the logic part.
In absence of voltage on this input, the logic part will continue to operate, but heating system and LEDS
(except for the BLUE one, arm) will stop working. Until when the heating system allows (about 2.30 h) the
machine may emit fog.
After that time the PCB will switch off automatically.

- 8 -

Installation and use manual for OT-U250PP & OT-U500PP

INPUT SIGNALS

9.1.2.

A

By connecting this input to positive, FOGGING SYSTEM is armed, blue frontal LED is switched on and

when the machine reaches proper temperature it means that it is ready for shooting.
In case of alarm, opening ARM input, the fog emission stops immediately, even if the time set wasn’t
reached.

S

Putting this input to positive, if FOGGING SYSTEM is hot and armed, starts fog emission for the set time

(see paragraph 12).

VALIDATION INPUT

9.1.3.
In order to validate this input, it’s necessary to insert the jumper W4. This input automatically generates

AND function with input S.
If any input receives the shooting command, the generator doesn’t emit fog if within 1 minute doesn’t
receive the command also from the 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 this input a validation sensor with a contact normally closed

connected to the terminal P-.
In order to check the correct operation of PV input, it’s necessary to remove the jumper W4.
When AND function is disabled, to each opening of PV input you will hear a “beep” for 5’’. At the end of the
test, re-establish AND function inserting jumper W4 again

OUTPUTS

9.2.

E

This output (NPN Open Collector) closes towards negative direction when the bag is empty. This output

(NPN open collector) closes towards negative when the fogging machine emitted fog for at least 100’’ or
when the bag is empty. The signal is activated by a sensor that detects the absence of liquid just while
shooting.
The empty bag signal is deactivated only making the RESET (see paragraph 14). For this reasons, if the bag is
not inserted, or there is an empty bag inside, FOGGING SYSTEM will detect it just after a shot.

F

This output (NPN Open Collector) closes towards negative when there is a malfunction (such as batteries

expired, fault of power supply or temperature control fault), which compromises the functioning of the
device and which requires a technical action.

T

This output (NPN Open Collector) closes towards negative direction when you open the bag door or

when the accelerometer detects a sudden movement (such as the detachment from the wall).

C

This output (NPN open collector) closes towards negative only after that the system has emitted fog for

the set time. If the emission of fog is interrupted (if there is an interruption of ARM command, if the glycol
finishes, if there is not thermal autonomy anymore) this output will not change its status.

Remember, it is necessary to connect all three outputs to an alarm central or an electronic
panel that can see all those information in real time and take proper action.
In order to avoid accidental activation with subsequent fog emission, the inputs are in

“negative security”, for this reason the disconnection of a wire does not cause activation.
So it is necessary to check carefully the reliability of connections and protect the cables to the control panel
to avoid the risk of accidental damages.

Example of connection of inputs with outputs of a standard alarm system

10.1.

In the diagram above the control panel, as example, provides to Orion Fogging system power supply
between 11 and 14V DC 250 mA max.
The ON/OFF output of this alarm is an Open Collector NPN opened when the system is off and it is stably
closed to negative as long as the system turned on.
The alarm output of the alarm is normally open and becomes positive during the alarm time.

Example of connection of inputs to an alarm with relay outputs

10.2.

ON/OFF output of this alarm central is an open relay when the system is off and it is stably closed to
positive as long as the system is turn on.

Example of connection of inputs with outputs of an alarm with open collector outputs

10.3.

Compared to B diagram, this alarm central has only open collector outputs.
The simplest action to take is to use 2 relays to create a connection similar to the one shown in the
previous diagram.

Example of connection of outputs to drive LEDS and / or relays

10.4.

In case of an empty bag, the EMP LED (EMPTY) will switch on.
In case of a fault, the FLT LED (FAULT) will switch on.
By opening the cylinders door, besides the TPR (TAMPER) turning on, the relay will switch as well.

Max power applicable on the outputs is 100mA

- 11 -

Example of connection of outputs with inputs of an alarm normally opened

10.5.

The outputs shown in the diagram are not always necessary, but only in cases where the voltage of pull-up
resistance is lower than that of power supply.

The outputs are normally opened and connected with input zones of the alarm control panel normally
opened

Example of connection of outputs with balanced inputs of an antitheft

10.6.

In this diagram, by putting a resistance with a value required by the alarm control panel used, in Orion
terminal with not used outputs the central will see the correct resistance. After the activation of an output,
a pull-down will occur causing the alarm in the corresponding zone.

Example of connection of outputs with anti-robbery connection.

10.7.

Using the special connector and enabling the option anti-robbery closing the Jumper W2,
you will obtain the immediate emission of the fog for the seconds that you have set even if
the fogging system is not armed.

N.B. Is recommend to use this function after a careful evaluation of the risks from a
security consultant

Meaning of front LEDS

11.

LED BLUE

When ON it means the machine is armed and, if hot, it’s ready to shoot.
Flashing means something is wrong.

LED RED

It is ON when the bag is empty

LED GREEN

Flashing means the heating process is in progress.
In this step the machine is heating but is not ready to shoot.
When ON (steady green light) means the machine is hot and ready for the fog
emission

IF THE BLUE LED IS FLASHING, TOGETHER WITH A CONTINUOUS SOUND FROM THE BUZZER, A

PROBLEM IS DETECTED. SEE PARAGRAPH 16

The symbol of empty bag, has the meaning of “RESERVE”
It means that, since the last bag reset the machine consumed at least 85% of the estimated range of the
bag.

Shooting time setting and fog Flow direction.

12.

To set the shooting time, after opening the cylinders compartment door, at the
top of the PCB, facing the board you must move the jumper in left position P3
(closer to the buttons S1/S2). Then, holding down the button S1 “SET”, 6 LEDs on
the front will flash and each flash is equivalent to one second.
If you press the button again, the shooting time is not added to the 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 any shooting

There might be cases in which, due to specific characteristic of the location, nozzle type, levels of
temperature and air pressure, degree of the fog density and light in the target area, the shooting time can
be increased or decreased accordingly by referring to the following formula:

(HxLxP) x D x V x I

HxLxP--------Height x Width x Depth of the area to protect
D-------------Density of the produced fog
V-------------Temperature and air pressure
R-------------Acceptable residue in case of saturation of V parameter
I--------------Intensity 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 humidity.

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 capacity: 116 seconds equivalent to 1500 cubic meters

The first value indicates in m³ the area to protect, the second one indicates the seconds of emission. The
value in m³ may vary depending on the density that you desire to obtain. Considering the first value you
obtain a density that guarantees a visibility of zero meters. With the second value you obtain a density that
guarantees a visibility of 1.5 meters. Naturally, in places where a slight residue is not a problem, it is
possible to increase the time of shooting. We remind you that more fog is released more time it takes to
have visibility again. Higher levels of fog over suggested limits may fill the room and leave a residue.
Any residue usually goes away by itself within 24/48 hours, otherwise, being soluble in water, it is enough
to use a wet cloth for cleaning.
If you desire to obtain an average of 1 meter visibility after 60 seconds, as specified by the standard, as
used as reference by all manufacturers of Fog generators, the number of shooting seconds must be
doubled.

FOG FLOW DIRECTION

12.1.

To ensure the right direction of the fog flow, it is recommended to insert a
screwdriver of the diameter of the hole and, without forcing, orient the nozzle in
the correct fog emission direction. This allows you to clearly see the direction and
keep it in place while tightening. To screw and unscrew the nozzle you should use
a pair of pliers in good condition to avoid damaging the plating. Do not over screw
the nozzle; it is sufficient that the Teflon nozzle does not move.
Do not direct the fog jet towards objects and walls less than 2 meters away or to
the floor if it is installed at a height lower than 2.50 meters (we advise against the
installation on the floor).

WARNING! After the fog emission and for a few minutes the nozzle is very hot RISK OF BURNS IF
TOUCHED by bare hands.

- 15 -

Installation and use manual for OT-U250PP & OT-U500PP

Nozzle Tamper

13.

The check of the obstruction of the nozzle is done with a little air flow, while a sensor check the pressure of
the internal circuit.
In case the sensor detects an increase of the internal pressure, means that there is an obstruction inside
the nozzle.
In the meantime, the output of Tamper will be activated; the buzzer will emit a sound with a fast frequency
with the flash of the red LEDs.
This condition of the alarm will continue until the system is disarmed and armed again.
As the little compressor that introduces the air flow emits some vibrations, its activation occurs only in the
following cases:

• When you press the button RESET for more than 5 seconds, besides the activations of the drop of

the motors, will start a cycle of monitoring of 15 minutes, in order to simulate the obstruction and
check the correct working.

• When the system is armed the cycle of monitoring starts. This cycle is the most important, because

as the system was disarmed probably was easier to go near the machine and obstruct the nozzle.
After 15 minutes, the compressor will stop automatically. If the system is disarmed and armed
again, the cycle will start again for 15 minutes.

• After the emission of the fog, as normally the zone where the machine is installed is the last where

the visibility is reduced, the generator remains vulnerable, giving the possibility to who generated
the alarm to attempt the sabotage. For this reason, after the emission of the fog the 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 the screws of the door, is sufficient to remove the bag and reset the
LED of empty bag.

In order to make the reset the jumper P3 must be
on the right position as you can see in the picture.

After that, insert a new bag until you hear the “click” of the plastic support entering in its housing, then
close the door.

N.B. When you 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

any alarm

Maintenance

15.

Orion generators do not require special care however, it is recommended the support of qualified and
authorized personnel for periodic annual monitoring, taking into account the following:

• Annually verify the functioning of the pump.

• Check the air tightness of the circuit and the switch functioning.

• The efficiency of the batteries is crucial to guarantee the operation

CHECKING OF THE PNEUMATIC CIRCUIT AND THE PRESSURE CONTROL SYSTEM

THE TEST CAN BE DONE JUST BY QUALIFIED PERSONNEL

Before starting the test of the pressure control it’s necessary:

• to remove the bag

• to be sure that the nozzle is cold

• to be sure that the nozzle tamper pump is activated

The pneumatic seal test must be done within a few seconds when the pump for nozzle tamper control is
turned on, as the nozzle temperature rises rapidly reaching temperatures that may cause serious burns.

The air coming out of the nozzle exceeds 200° C.
IT’S ADVISABLE TO USE GLOWES

1. Obstruct the nozzle with soft and insulating material (for example an eraser).

2. Keep the nozzle obstructed, press the button P3 previously moved in RESET position (see paragraph

14) and keep it pressed until you hear that the pump is activated.

3. Wait 30’’ for the activation of the buzzer.

4. Remove the obstruction taking away your hand quickly to avoid being in contact with the hot

emission of air.

The buzzer must stop.

• If there is any loss inside the pressure circuit, within 30’’ the buzzer will be activated.

• If after 30’’ you don’t hear the buzzer, may be a loss inside the circuit; please contact the service

center.

• If after removing the obstruction the buzzer doesn’t stop, it means that there is an obstruction;

please contact the service center.

Reset from Fault condition

16.

This process is useful to discriminate false interpretations of faults caused by electrical shocks or serious
problems on power supply from thermal loop problems.

1. Serious fault signal occurs with a first phase when the buzzer emits a continuous sound for 20

minutes and blue led flashes, the output FAULT immediately switch (if the generator is
disconnected and connected again you can go directly at point 3)

2. After 20 minutes, the buzzer stops, while blue led goes on flashing, the FAULT output remains

closed. This phase remains permanently, until the machine is completely disarmed.

3. When you connect again the machine, blue and red LEDs flash alternately and no sound is emitted.

This phase lasts for 30 minutes, then, the output FAULT is reset and the generator start to work
again. If during this process the generator is disconnected, when you connect it again the time start
again from the beginning and for 30 minutes.

If at the end of this process, the generator start to work again regularly is not necessary any further
operation.
If occurs again the fault condition within the following 20 minutes, it’s necessary a check from the
assistance center, or to send the machine back to the factory.

Defects Possible solution

17.

DEFECT FOUND

POSSIBLE CAUSE

POSSIBLE SOLUTION

When you arm the machine
you hear an internal buzz, like
a motor

The compressor is checking that
there are no obstructions in the
circuit of fog emission

When the machine is armed, for 15
minutes the compressor will monitor the
nozzle. After this time it will deactivate
automatically: if the fogging system is
disarmed, the compressor will go on with
it reaches 15 minutes.
If the machine is disarmed and then armed
again, the count will start again from zero.

When you arm the fogging
system, a little fog flow goes
out from the nozzle even if the
machine has never shot
before

During testing phase in the
factory, we also test the quality
of fog in all produced systems, a
little quantity of the fog liquid
remains in the ducts

This emission occurs just at first activation,
it will decrease visibly with any activation,
until disappearing completely.
After an eventual disassembly and
reinstallation or after the transport of the
machine, with the first activations a little

flow of fog can occur again.
The 3 frontal LED are flashing
and the buzzer emits 1 beep
per minute

The tension on +12 V input is too
low or too high

Check the external power supply or the

alarm unit

The buzzer emits 2 beep per
minute

Low battery but possible shot

Verify/replace battery - See paragraph

MAINTENANCE
The buzzer emits 3 beep per
minute

Low battery but possible shot

Verify/replace battery - See paragraph

MAINTENANCE

The buzzer emits 10
continuous beep per minute

Batteries not present Insert battery
Connector not inserted correctly Remove and reinsert the connector
Verify that jumper W5 is inserted Insert jumper W5

The machine is armed
(BLUE LED ON)
but doesn’t shoot

The front RED LED is on

Bag reset has not been made Reset as

described in paragraph 15

Bag is in reserve or empty-Change the bag

as described in paragraph 15

The front GREEN LED flashes

The heat exchanger has not yet reached

the minimum temperature of shooting,

wait for the led to stop flashing standard

heating time: 60 min.

Installation and use manual for OT-U250PP & OT-U500PP

The machine doesn’t shoot
immediately after arming

For safety reasons and to avoid false fog

emissions during power on, when the

machine is armed, it becomes operative

only after 20’. After this time, the emission

is instantaneous.

Wiring error

Verify that the alarm, once activated has

tension on connectors of at least 12 V

between GND(5) + SHOOTS(4)

BLUE LED is flashing
The buzzer emits a continuous
sound
BLUE and RED LEDS are
flashing alternately

Overvoltage power line
(110/220 V)

Try to reset. See paragraph 17

In case of unsuccessful restore the PCB can

be damaged, contact the assistance

service.

Over temperature of the PCB

Check there is sufficient ventilation around

the machine. See paragraph 17

To reset see paragraph 17

Disturbance/ interference or
potential differences between
devices

In the case of strong interference

(lightning) can occur a thermocouple

reading error, make a reset.

See paragraph 17.

In case of unsuccessful restore can be

occurred a potential difference or a fault.

In large size plants or with more than on

fogging system connected with the same

central, in rare situations, it may occur

that there are potential differences

between the equipment and it could be

necessary to uncouple

Error in the thermal loop

Possible fault of: thermocouple, resistance

or fuse cable. Don’t try to repair

Contact the assistance service center.

Impossible to arm the
machine BLUE LED doesn’t
switch on

Wiring error

Check on the terminal with a tester that

when the alarm system is tuned on there

is a minimum voltage of 11 V between -

GND (5) + ARM (3).

Cannot arm, BLUE LED does
not become on.

Wiring error

Test the terminal that there is a minimum

voltage of between 11V - GND (5) + ARM

(3), when the anti-theft system is activated
When you press the reset
button you don’t hear the
sound of the buzzer, the
frontal LED are flashing but
the RED LED does not reset

The Jumper P3 is in the “SET”
position

Warning in this case shooting
time is reset to zero
Bag reset - Paragraph 15

Shooting time setting - Paragraph 12

Setting the shooting time, the
buzzer does not sound and
the LEDs do not flash

The jumper P3 stands in the
“RESET” position

See the setting mode of the shooting time

at paragraph 13
