Fig. 1.1
The SparkShield2(A) spark arrester reduces the risk of sparks,
cigarette butts or other sources of ignition reaching the filter to
an absolute minimum. Inspection hatches1(E) are placed
around the SparkShield to monitor the system and determine
the need for preventive maintenance.
The OilShield2 (F) limestone feeder is placed between the spark
arrester and the filter. Limestone is applied in small quantities
and makes sticky welding fumes behave like dry welding fume,
enhancing filter cleaning and filter cartridge life. The limestone
reduces the risk of fire due to sparks and spontaneous
combustion to a minimum.
The ShieldControl (J) fire detection panel processes the
detection sensor signals, sets the alarm and activates the

suppression system. In case of alarm, a fire alarm sounder
(K) will go off. Operational reliability in the event of a power
failure is assured by a battery pack. To secure the overall
functionality, ShieldControl monitors open or short circuit of
wiring loops of detectors and the suppression system.
When a fire is detected, the system can be activated manually
at the manual call point (L).
Automatic detection is triggered by heat, sparks or smoke. The
filter is fitted with heat detectors (H) above the dustbin and at
the top of the filter. Spark detectors (C) are placed near the
filter outlet and in the duct after the filter. A smoke detector
(D), suitable for air ducts, is placed in the duct after the filter.
The inlet and outlet duct of the filter are fitted with pneumatic
sliding valves (B). If there is a fire, the valves close and cut off
the oxygen, thereby choking it. This constrains the risk of
escalation. When the extraction system is switched off, the
valves are closed as well to create a safe situation. The valves
have reed contacts to monitor the closing function; the filter
system software runs a periodic check.
The filter is fitted with one or more FlameShield (I) aerosol fire
extinguishing generators. The generators are placed directly in
the filter housing and do not require plumbing. FlameShield
requires no maintenance and has a service life of 10 years. If
there is a fire, FlameShield is activated by the fire detection
panel after the sliding valves have closed. FlameShield self
activates at 300°C (572°F). Fire suppression is rapidly achieved
through interference between the aerosol and the flames’ free
radicals, terminating propagation of the fire. The aerosol
remains active during 30 minutes after activation, thus
preventing re-ignition. The amount of aerosol is proportional to
the filter volume and can be easily adapted by adding
generators.
The system control panel SCP (M) controls the filter and fan
operation. If there is a fire, it will get a signal from the fire
detection panel and close the sliding valves, stop the fan and
shut off the supply of compressed air. The filter compressed air
connection is fitted with a solenoid valve (G) that will allow the
compressed air tanks to depressurize outside of the filter and
prevent any fresh oxygen from reaching the fire.

1.4 System maintenance
The entire system including the ShieldControl panel must be
tested periodically in accordance with the national fire
protection association requirements or the authorities having
local jurisdiction.
The maintenance and testing procedure of the separate
components is described in the relevant chapter.
General instructions

The fire suppression system can be
activated in two ways:
- automatically by heat, sparks and/
or smoke detectors
- manually at manual call point
If there is a fire, the automatic
sequence of events is as follows:
- acoustic fire alarm goes off
- fan motor is switched off
- release of compressed air through
solenoid valve
After a delay of ± 5 seconds:
- sliding valves close
- release of aerosol by FlameShield generators during 60
seconds
After activation, the FlameShield aerosol remains active for at
least 30 minutes to prevent re-ignition of the fire. In this way,
damage to the filter installation, as well as consequential loss is
kept to a minimum.

Alarm resistor
The heat detectors are fitted with a 470 ohm alarm resistor
(RAL) placed in series with the switching contact circuit. The
alarm resistors have no active function but do not interfere with
the functionality of the ShieldControl 5k1 fire detection panel
either. In case of a short circuit it will activate the fire alarm.
• Connect the heat sensors in accordance with the electrical
diagram on page 29. Use shielded cables.
6.4 Functional test
The operation of the heat detectors can be checked in two ways;
by measuring the ohm resistance:
- Gently heat the detectors using a heat gun or heat lamp.
by connecting them to the fire detection panel:
- Gently heat the detectors using a heat gun or heat lamp.
- Check the system status. ShieldControl should indicate a fire
in Zone 2.
To perform the test, proceed as follows.
•Observe the functional testing instructions as
described in paragraph 4.4.
• Functionally test all heat detectors.
• Allow the detectors to cool down.
• Reconnect the heat detectors.
6.5 Maintenance
To be able to operate properly, the heat detectors must be kept
clean. They should be tested periodically in accordance with the
national fire protection association regulations or as directed by
the authorities having local jurisdiction.
• Clean the detectors regularly and gently.
• Test detectors for proper functioning; refer to paragraph 6.4.
• Place detectors back in the filter housing.
Any detector that has been involved in a fire, abused or
damaged must be tested and replaced if necessary.
WARNING
Not using shielded cables can lead to a false alarm by
external high voltage sources and might activate the
alarm.
ATTENTION!
Notify all parties involved that you will be testing the
fire safety system; refer to paragraph 1.4.
WARNING
Do not overheat the setpoint of the detector by more
than 55°C (131°F) because this can change the
default temperature setting.

• Mount the spark detector “EOL” in parallel after the one
without (“no EOL”) according to the electrical diagram on
page 29.
The spark detectors are provided with the following coloured
wires:
• Connect the red and black wire to the 24V auxiliary
connection of the ShieldControl fire detection panel.
• Connect the white and blue wire to Zone 1 of the
ShieldControl panel.
• Connect the green wire to earth/ground.
The EOL resistor over Zone 1 of the ShieldControl panel has
become obsolete and has to be removed because it is already
premounted in the spark detector.
• Remove the EOL resistor over Zone 1.
7.4 Functional test
The easiest way to test the spark detectors is to expose them to
daylight. Both detectors must be tested separately before the
system is put into operation.
To perform the test, proceed as follows.
•Observe the functional testing instructions as
described in paragraph 4.4.
• Loosen the fixation screw and remove one of the spark
detectors. That will expose the sensor to daylight.
• Check the system status. ShieldControl should indicate a fire
in Zone 1.
• Replace the spark detector and fasten it using the fixation
screw.
• Press the SYSTEM RESET button on the ShieldControl panel.
• Follow the same procedure for the other spark detector.
7.5 Maintenance
To be able to operate properly, the spark detectors must be kept
clean. Dirty lenses might influence their sensitivity. Both
detectors must be cleaned and tested periodically in accordance
with the national fire protection association regulations or the
authorities having local jurisdiction.
Cleaning intervals differ per situation and regular checks need
to be performed to set the cleaning interval for your specific
situation.
To clean and test the spark detectors, proceed as follows.
• Make sure the FlameShield module(s) is/are disconnected.
• Loosen the fixation screw and remove one of the spark
detectors.
• Clean the lens gently with a soft cloth or similar. In this way
it is exposed to daylight at the same time (ref. paragraph
7.4).
• Check the system status. ShieldControl should indicate a fire
in Zone 1.
• Replace the spark detector and fasten it using the fixation
screw.
• Press the SYSTEM RESET button on the ShieldControl panel.
• Follow the same procedure for the other spark detector.
If in both cases a fire is detected in Zone 1 of the ShieldControl
panel, the spark detectors are functioning properly. If no
detection takes place, the lens might still be polluted or the
spark detector is broken.
• Clean and test once more.
• If necessary: replace the broken spark detector.
• Reconnect the FlameShield module(s).
Any detector that has been involved in a fire, abused or
damaged must be tested and replaced if necessary.

9.1 Product description and operation
Double activated pneumatic sliding valve with 5/2 solenoid, to
be installed by two pieces (before and after filter system).
When the filter system is in operation the valves are open. In
case of an alarm or power failure or when the fan is switched off
the valves are closed. Correct closing of the valves is monitored
by the reed contact.
In case of fire, the sliding valves close automatically, operated
by pneumatic cylinders. In sequence to a lack of oxygen the fire
is supposed to choke. This will also minimize risk of escalation
or spreading of smoke.
9.2 Installation
Location:
- 1st sliding valve: in filter inlet duct
- 2nd sliding valve: before or after spark and smoke sensors in
filter outlet duct
- to be mounted in vertical position
It is strongly recommended that the sliding valves be installed
indoors. If they are installed outside, however, ensure that they
are protected from rain and snow. Avoid installation where
compressed air can cool down below its dew point to prevent
damage to the pneumatics.
The sliding valves can be mounted:
- during installation of a new ductwork
- in an existing duct
To mount the sliding valves, proceed as follows.
Fig. 9.1
• In case of installation in an existing duct: cut away a piece
of the existing duct as indicated in the table below.
• Slide a connection flange (B) into both duct ends (A).
• Place the sliding valve (D) in between and fasten it using the
quick release clamps (C).
• Fasten the connection flanges using self-tapping screws.

Setting closing speed of the sliding valves
The closing speed of the valves can be set by the air pressure.
• Set the closing speed of the valves to 4-5 seconds arranged
by the air pressure.
Do not set the valves to faster than 4 seconds. If there is a fire
alarm, the fan is switched off and the sliding valves are closed.
The 4 seconds give the fan enough time to reduce speed and
prevents damage to the duct by negative pressure. Do not
select speeds slower than 5 seconds either, since the
FlameShield modules are activated 5 seconds after the fire
alarm.
Post installation checks
• Check electrical connections.
• Check pneumatic connections.
• Check bolts and nuts for correct tightening.
9.5 Functional test
The sliding valves can be tested manually by pushing the test
button (A) on the 5/2 solenoid valve.
• Functionally test both sliding valves.

9.6 Maintenance
In order to function properly the sliding valves must be
inspected regularly.
WARNING
Keep the compressed air feed line away from places
that can become hot by fire. Do not use the
compressed air supply from the filter because this will
be shut off in case of fire. Do not use filter or duct as
support for compressed air hoses.

10.1 Product description and operation
Fig. 10.1
Normally closed 3-way 2-position solenoid valve.
When the connected filter system is in operation, the solenoid is
activated and compressed air is supplied to the cleaning system
of the filter (port P and A are open). If there is a fire alarm or
power failure, the solenoid will return to its normally closed (NC)
position, closing port P and opening port R. In this position
compressed air escapes from the filter and it is unable to
execute a filter cleaning procedure. This prevents fresh oxygen
from reaching the filter in case of fire.
Fig. 10.1
10.2 Installation
Location
The solenoid valve is placed in the main compressed air line
between pressure reducer and filter unit. It is recommended to
mount the valve on the filter housing.
• Mount the solenoid valve at an appropriate position.

11.1 Product description and operation
FlameShield1is a fire suppression generator designed to be
installed directly into the filter system. FlameShield is activated
by the ShieldControl fire detection panel 5 seconds after a fire
alarm.
The FlameShield is designed to suppress or extinguish filter fires
of EN 2 Class A and NFPA 10 Class A (normal or solid
combustible material in Plymovent filters).
In 5 to 10 seconds, the filter volume closed by the sliding valves
is filled with a potassium aerosol. This material reacts with the
free radicals in the flame. The free radicals react with the
aerosol instead of the fuel and the chain reaction is stopped
immediately. The residue is a negligible amount of harmless and
stable potassium hydroxide salt (KOH). This reaction also uses
energy from the fire.
After activation the aerosol remains active for at least 30
minutes, which also prevents the fire from starting up again.
11.1.1 Transport and storage
To avoid damage, the following conditions for transport and
storage should be adhered to.
- Do not drop.
- Store between -50 and +100°C (-58 and +212°F).
- Relative humidity during transport and storage: max. 98%.
If FlameShield is stored in accordance with the above-
mentioned conditions, shelf life of the aerosol generator is 15
years.
11.2 Installation
• Refer to Fig. I on page 28 for the required number, type2and
