When the Metal Detector is centered with respect to the areas where luggage and metal
personal effects are deposited or recovered, these objects are unlikely to move close to the
device and cause alarms.
2 MD
orientation
The archway must be positioned with the TX antenna on the side of the X-ray unit. This layout
places the RX antenna - that is most sensitive part of the archway - as far as possible away from
the potential sources of electrical interference contained into the X-ray unit (mainly the monitor
and the conveyor belt motor).
NOTE: with this configuration, the power supply socket for the MD must be on the X-ray unit side.
3 Distance between the MD and the X-ray unit
Check the distance between the TX panel and the X-ray unit (refer to table ‘Recommended
minimum distance’ above).
4 X-ray unit anchoring
The X-ray unit must be firmly anchored to the floor to prevent its mechanical parts from
vibrations.
5 Sources of vibration:
Strong gusts of air:
remove the cause (f. i., a door slam), if possible. EVA procedure
(see EVA programming command) can be carried out to compensate vibrations.
Objects, panels or furniture in direct contact with the MD:
no objects, panels or
furniture shall be placed in direct contact with the MD.
6 Sources of vibration: Unstable Floor
The MD gate shall be anchored to a stable floor. Avoid installing on wood or metal platforms
unless necessary. In this latter case, contact CEIA for additional information
7 Anchoring the MD to the floor
ATTENTION: this step must be performed only once the setting and the environmental interference level
have been tested and found to be compatible. Refer to ‘Anchoring the MD to the floor’ section for details
.
The MD must be firmly anchored to the floor.
8 ‘Fixed’ metal masses
Any large object positioned close to the MD shall be only made of plastic or other non-metallic
material (refer to table ‘Recommended minimum distance’ above).
9 Moving metal objects
Doors or other large structures made of metal shall be kept far from the MD (refer to table
‘Recommended minimum distance’ above).
10 Low-power Electrical/Electronical Devices
The distance between the MD RX antenna and electric/electronic devices should be greater than
1 m (3.3 ft).
11 High-power electrical conductors and Electrical/Electronical Devices
These sources should be as far as possible from the MD RX antenna.
12 Distance between the MD and the Security Screener in charge
The position predisposed for the Security Screener in charge should not cause the MD to detect
his own metal objects (i.e. transceivers). Suggested distance is 0.5 m (20’) minimum.
