7.1 Product description and operation
Set of two infrared spark detectors. The spark detectors are
sensitive to the near IR light between 0.4 to 1.1 microns
wavelength.
When glowing particulate from the burning filter enters the field
of view of the detector, the detector responds by sending an
alarm to the ShieldControl fire detection panel.
7.2 Installation
Location:
- in filter outlet duct
- face to face (180° apart from each other) in the same vertical
plane
- min. 2,5x duct diameter from bend or branch
The spark detectors can be mounted without having access to
the inside of the duct. In this case you will need the supplied
insertion tool.
In case of a new or disconnected duct allowing access to the
inside , proceed as follows.
Fig. 7.1
•
Make a hole Ø 38 mm (1.5 in.) in the duct using the supplied
hole saw.
• Mount the flange (D) in the duct using the split washer (C),
washer (B) and nut (A).
• Tighten washer and nut on the flange.
Fig. 7.1
In case of no access to the inside of the duct, proceed as
follows.
Fig. 7.2
•
Make a hole Ø 38 mm (1.5 in.) in the duct using the supplied
hole saw.
• Slip nut (B), washer (C) and split washer (D) on the insertion
tool (A) until the tool fits tightly on the flange (E). The nut
and washer should be loose on the shaft of the tool.
• Push the flange completely through the hole in the duct and
insert the split washer by rotating it into the inside of the
duct.
• Gently pull the flange back through the hole with the
insertion tool so it rests against the split washer inside the
duct.
• Tighten washer and nut on the flange.
• Remove the insertion tool by loosening the wing nut and
pulling straight back and twisting if required.

•
Insert the spark detector lens (A) into the flange (C).
• Fasten the detector using the supplied fixation screw (B).
• Follow the same procedure for the second spark detector.

7.3 Electrical connection -Zone 1-
To be sourced locally:
- connection wire: 5 x 20 AWG shielded cable
Wiring
Fig. 7.4
The spark detectors (A) must be wired in parallel in the supplied
junction box (B). Each set consists of one spark detector with
EOL resistor (“EOL”) and one without (“no EOL”), which is
marked on the spark detector housing.

7 SPARK DETECTOR SET
Scope of supply:
- spark detector*) +
fixation screw
- spark detector REOL*)
**) + fixation screw
- junction box
- installation set (hole saw
Ø 38 mm + insertion
tool)
*) with alarm resistor (RAL)
**) with end of line resistor
(REOL)
WARNING
To avoid dirtying the lens, never mount the spark
detectors on the bottom of the duct.
Installation is easier if the inside of the duct is
accessible.
WARNING
To prevent false alarms, ensure that no light can get
between the flange and the duct. Seal any holes with
metal foil. Do
not use duct tape since this may let
through infrared light.
