DESCRIPTION
Operating Principle
In general, a modern Metal Detector for checking people in transit comprises:
• An electronics unit, made up of:
• a variable magnetic field
generator
• a receiver
• a processing and control unit,
which determines if the variation
of the received signal is due to
metal masses in transit of a
certain shape, volume or
composition
• a transceiver antenna
comprising a pair of columns or
panels

SOME HELPFUL GUIDELINES FOR METAL DETECTORS
The parameters which best characterise a Metal Detector are
as follows :
• Discrimination:This parameter reflects the variation in
sensitivity between potentially dangerous metal objects
(due to their particular shape compared with their volume)
and personal effects (such as coins, keys, watches,
buckles, etc...). When a detector with low discrimination is
used, personal effects can cause a large number of false
alarms, rendering the system ineffective in practical terms.
• Uniformity in detection efficiency: This parameter is
closely connected with the linearity of the magnetic field
generated inside the Metal Detector. Generally speaking,
the greater the uniformity, the better the discrimination.
• Sensitivity: alarm activation threshold: the greater the
sensitivity, the smaller the metal mass which will cause an
alarm.
• Interception speed: the transit speed of a person through
the metal detector archway usually depends on situational
factors, and can vary considerably. The sensitivity of a
good Metal Detector should be independent of the speed
of transit.
• Programming: C.E.I.A. have designed their Metal
Detectors to include the possibility of selecting the
settings of the operational parameters: this predisposition
facilitates both the installation of the device (rejection of
external sources of interference) and adaptation to the
user’s requirements (orientation towards ferromagnetic
and/or non-magnetic metals). This feature is particularly
important in the detection of weapons made of light metal.
• Immunity to interference: environmental electromagnetic
interference of mechanical or electrical origin is the
principal cause of false alarms, because it augments the
effective signal of the mass to be detected. Particular
attention must therefore be paid to the Metal Detector’s
immunity to this type of interference.
• Harmlessness to life support systems and storage media:
the field emitted by the Metal Detector should be below the
values set by international standards which guarantee
harmlessness to life support systems such as pace-makers,
adrenaline pumps etc. Observance of these limits also
means that there is no effect whatsoever on computer-type
storage media.
• Synchronisation: multiple installations of Metal Detectors are
very common (just think of an airport departure terminal). To
allow several Metal Detectors to operate in a restricted area
without influencing each other, it must be possible to
synchronise them without the help of cable connections.
• Power supply flexibility: wide tolerance range for the input
voltage and emergency batteries which cut in automatically
ensure that the Metal Detector continues operating in the
case of variations or cuts in the mains supply.
•Set-up and calibration with respect to the reference sample:
a modern Metal Detector must allow its installation in
whatever environment, without any interference caused by
other external devices. The security level may usually be
adjusted acting on sensitivity: CEIA’s Metal Detectors are
also provided with a special command (IS) allowing the
direct selection of the functioning parameters which
determine a security level conforming to the International
Standards.
• Maintenance: a modern Metal Detector generally
incorporates a self-diagnosis system which identifies any
sabotage and which also signals accidental faults. Modular
construction furthermore allows the faulty parts to be
replaced quickly and easily, thereby minimising the time the
device is out of operation.

Construction of the Metal Detector
The CEIA Metal Detectors described in this manual are most commonly used in airlock-type access cabins.
They are made up of an electronics unit and an archway antenna;
The antenna is constructed in exceptionally strong synthetic material, and in the shapes described in the
following pages. The standard colour is light grey.
Each antenna unit comprises a transmitter and receiver antenna with identification marks (Cin the figures
below), both on the side which faces into the transit passageway and on the electronics unit connecting
cable. The labels are green on the transmitter antenna and red on the receiver. Connection between the
electronics unit and the antennae is via two cables (one for the transmitter and one for the receiver).

INSTALLATION
Before proceeding to install the device read the warnings and instructions in this section carefully. Please
note that CEIA is not responsible for any damage that may result from installations that do not follow these
guidelines.
General installation notes
Unpacking the Metal Detector
Handle the material with care during unpacking operations.
All accessories needed for installation of the Metal Detector (screws, wrenches etc.) are supplied with the
device.
Transit requirements
The probe will be positioned, according to the requirements dictated by the transit, in such a way as to allow
the maximum flow of people and observance of the rules for installation.
Stability
To operate properly the antenna should not be subject to shocks or movement. Follow the installation
instructions and ensure that the Metal Detector probe is stable and anchored firmly to the ground.
Perpendicularity and alignment
During assembly of the panel antenna, carefully check the perpendicularity and alignment of the transmitter
and receiver sections, ensuring that they are anchored at the right distance.
Holes
It is strictly forbidden to make holes in the Metal Detector antenna or to insert screws in positions, or of
lengths, not expressly indicated by CEIA. Damage due to such actions is not covered by the product
warranty.
Mains power supply
Check that the voltage supplied by the mains corresponds to the detector’s supply voltage: this latter is
indicated near the device’s power supply socket and on the test card.
A protection switch should be connected up between the mains supply and the detector.
The use of a different mains voltage may damage the equipment. The protective ground conductor must not
be fused.
Models with electronics unit separate from the probe
During set-up, the connecting cables between the electronics unit and the antennae should be suitably
distanced from other electrical cables and mains supply lines. If this is not possible, enclose the cables in
iron pipe shielding of suitable diameter.

Electromagnetic compatibility
C.E.I.A Metal Detector is an apparatus which adapts well to the widest possible range of working
conditions, and is especially immune to parasitic electromagnetic interference; however, to obtain best
results, particularly at high sensitivity, a few precautions relating to the structure in which the detector is
going to be placed should be taken. Sources of interference can be of two types:
a) of a mechanical nature
b) of an electrical nature
Interference of a mechanical nature
As you know, a Metal Detector generates an electromagnetic field able to induce in its receiving section an
electromotive force which, when modified by metal objects in transit, makes the appliance operate. The flux
of the magnetic field, however, also invests the space surrounding the probe.
The first rule is to ensure maximum rigidity in neighbouring metal structures and stable anchoring of
the metal detector probe.
Neighbouring metal structures can introduce field absorption, which can be caused by:
1) the movement of metal masses, either large or particularly near the antenna (doors, ceilings,
etc.);
• Fixed metallic structures located in the immediate vicinity of the Metal Detector can be more
suitably replaced with panels in Formica, Bakelite, polycarbonate or other insulating materials. If such
structures make up the supporting structure of a cabin, they must be extremely solid so as to avoid any
possible shifting during the movement of the doors. It is however advisable to distance the metal
detector from lateral metal panels by at least 6cm (the actual distance will, however, depend on the
mass of the structure).
• Ceilings of sealed cabins:allow breathing spaces so as to avoid movement of the ceilings due to
compression of air during movement of the doors.
• Doors:if the doors are made of metallic material, they must be located at a distance of at least 50cm
in the panel models, and 60 cm in the column models (such distances are approximate and may vary
depending on the structure of the doors); the loop formed by the metallic profiles of the door must be
insulated (see fig. II-2a/b/c).
If the doors are of insulating material the precautions described above are not necessary. It is
however advisable, especially if the doors open towards the Metal Detector, that the lock be placed on
the door-post and that the opening into which the door-bolt enters be made of a non-metallic material
(for example, Teflon). The hinges should be limited in size and in peripheral movement. Any swing-
back brackets should have their body attached to the door-post and not to the door. Any decorations,
movement mechanisms, screws, etc., should preferably be made from insulating material: if this is not
possible, it is advisable to limit the size of such fixtures and to use non-magnetic material (brass,
aluminium, stainless steel, etc.).
• Weighing devices: should have the minimum possible number of moving metal parts adjacent to the
Metal Detector antennae.
2) presence of electromagnetic loops made up of structural components (metal frames, glass doors,
metallic ceiling strips, etc.) that because of movements or vibrations are not stable. If the loops
are subject to movement, they must be distanced from the antennae or eliminated by means of insulating
(see fig II-2a/b/c). Should the loops be fixed, originating from structures and sections that surround the
Metal Detector, they must be insulated by means of an appropriate split or made electrically stable by
welding .
• Metal door-frames, metallic ceiling strips or unstable supporting floors: place at a distance,
replace with non-metallic materials or insulate with appropriate cuts the loops formed by such fixtures.
• Doors:insulate any possible structural loops (see fig. II-2a/b/c); if there are spring levers for swing
doors they should be insulated so as to avoid forming a loop.
• Thresholds:if made of metal they should not touch the base of the cabin thereby forming an unstable
loop.

Electrical interference
Such interference is caused by the proximity to the antennae of power supply cables (electromagnetic field
generated by alternating currents) or impulsive sources of electromagnetic interference (electric motors
with a high ignition absorption and related power supply cables, fluorescent lights, emergency generators, air
conditioning units, remote-control switches, etc.).
1) Power supply cables: these should be at a distance of at least 20cm from the sensitive probe,
particularly from the receiving part (the distance depends on the circulating current) and twisted with a
pitch not greater than 2,5cm (should this not be possible, they should be inserted into a screening tube
made of ferrous material at least 2mm thick). The cables serving lights or other equipment should not
under any condition create loops in the vicinity of the probe.
2) Impulsive sources: these should either be placed at a distance, eliminated or screened.
•Fluorescent lights:place the lamps and related reactors at a distance from the Metal Detector,
particularly from the receiving part marked with a red stamp; where possible substitute fluorescent
lights with filament lights.
•Electric motors: Equip electric motors with adequate mains screening and filters. Use of a.c.
rather than d.c. motors is recommended. Motors in the immediate vicinity of the Metal Detector's
probe should be screened by means of cylindrical iron casings with diameters big enough to
enclose the motors and with a minimum thickness of 2 mm; these cylinders must be drawn, of the
type without lengthways welding.
• Electrical locks:if these are positioned near the probe of the Metal Detector, it is advisable to use
a type provided with screening. The use of motorised locks is preferable, since they absorb a lower
level of current on ignition.
•Electromagnets, remote-control switches and continuous current motors:twist the related
power supply cables with a pitch not greater than 2.5 cm.
•Loudspeakers, transformers, intercoms:screen or place at a distance from the receiving part of
the Metal Detector (recognisable by its red mark); to this end it is also possible to swap the
positions of the receiving and transmitting antennae. In the case of a sealed cabin intercom it is
advisable to arrange that it be fastened to both sides of the door, and to place it next to the
transmitting antenna.
• Detector mats:it is advisable to use resistance-varying or pneumatic models: electrical-contact
types should only be used with the insertion of a resistance of at least 10Ωin series at each
segment.
Inhibition of the Metal Detector
As a further resource, there is always the possibility of inhibiting the Metal Detector in correspondence
with the interfering phenomenon, but only in cases where such action does not undermine the overall
security of the apparatus..
Orientation of the columns
If there is a localised source of electrical interference, the effects can be minimised by rotating the columns
on their axes: see the procedure described in the Maintenance section.

Installation of coupled metal detectors - synchronisation
When two or more Metal Detectors are to operate near each other (generally within 10 metres), they must be
synchronised by choosing an appropriate transmission channel for each one (CH function).
1. Follow precisely the arrangement of the TX and RX antennas and the minimum distances indicated.
The TX antenna can be recognised by the power supply connector.
2. Select the 0 setting for the NL function (only on model 02PN8 HI-PE).

a Metal Detector effects a data transfer, the line
goes down to "low" level ( 0V ) and indicates to the
other devices that the network is busy.*
