5.
The test in 4 above should be repeated with differing size target items as appropriate to the
operational requirements and at varying speeds as above,
6.
Should a target item fail to be detected check the Sensitivity Level is correctly set for that
size of object,
7.
Any failure or malfunction should be investigated immediately,
8.
Once tests have been completed the Alarm Counter (see section 4.1.5) and the Traffic
Counter (see section 4.1.6) may be reset ready for the day’s operation.
5.3 ALARM STATE
If a person triggers an alarm when passing through the archway, the operator should instruct the
individual to step outside the walk-through and remove any metal objects from their body and/or
clothing. The operator should then either scan the person with a hand-held metal detector
(
ThruScan
s-dS-dV-dX), or ask the person to re-enter the WTMD.
If an alarm sounds after the person re-enter the walk-through, he/she must be rescanned with a
hand-held metal detector-HHMD and the cause of activation should be determined. One should also
remember a metal possibility by prosthesis organs.. i.e. pacemakers, etc.
The zone lights facilitate the screening process by indicating the location of all
causes of alarm
activation within 9 zone areas. In cases where there is more than one object, the lights appear in
each array that requires investigation. This enables the operator to know from which area(s)
objects require removal and to concentrate on the problem areas when hand scanning, resulting in
improved overall security and increased transition.
If the operator finds a weapon or another forbidden object, he or she should follow the
in-house screening procedures and the supervisor’s instructions regarding the appropriate
response.
NOTE: Remember that the cause of every alarm MUST be determined. If in doubt the
operator should consult their authorized personnel or manager
.
6 TECHNICAL SPECIFICATIONS
6.1 ELECTRONICS
Digital-controlled, pulse induction, multi-zone metal detector; target location is discernible on the
left and right sides of the body, from head to toe in 9 distinct zones. (Both the detection and
control circuitries comprise microprocessors.) Modular-designed electronics facilitate mounting and
maintenance easily.
6.2 DETECTION FIELD
ThruScan
’s multi-zone detection field provides and completes horizontal and vertical uniformity.
The sensitivity of each field can be adjusted to meet the requirements of specific security
applications
(*only for
sX/sX-i/sX-WP
).
ThruScan
’s unique design enables the operator to
identify targets within 9 zones. Detection is precise, regardless of a target’s location or orientation
within the archway.
