7. SUPERVISOR RESPONSIBILITIES
7.1 CALIBRATION
Calibration settings of walk-through metal detectors are dependent upon individual security screen-
ing requirements and, therefore,
must be the responsibility of the screening installation .
Program and Sensitivity settings should be established at a level that permits the detector to detect
all forbidden objects that can be reasonably expected to appear at a particular screening station.
Actual forbidden objects should be used as targets for initial calibration.
7.2 FAA TEST PIECE
Garrett manufactures an Operational Test Piece (OTP) made to the specifications of the U. S.
Federal Aviation Administration (Garrett Accessory #1600600). This piece is intended to simulate a
small firearm.
If the OTP does not represent a specific security requirement then a different test piece(s) should
be considered.
7.3 TESTING
It is imperative that a standard test program be developed for walk-through metal detectors within a
security system. The various tests should be made on a regular basis to ensure that each unit is
properly calibrated and is detecting metal. The OTP has been designed to serve as a basic instru-
ment for use in such a test program.
A test program should include passing the OTP and/or other objects through each metal detector at
various specified heights and horizontal positions, with the OTP (objects) held in different orienta-
tions. The number of repetitions required at each level with corresponding successful alarms should
be established, and this testing system should be adhered to consistently.
Included in the test procedure should be the requirement that the tester be free of all metallic items,
including shoe shanks, prior to arming himself with the OTP. A hand-held metal detector can be used
to confirm that the tester is “clean” of extraneous metallic items.
7.4 ANKLE BOOST
The MT 5500 incorporates the ability to adjust the sensitivity at ankle level without increasing sen-
sitivity throughout the passageway. The factory setting is with standard ankle boost to allow easier
passage of shoes containing metal shanks. Two additional levels of boost are available for higher
levels of security.
This adjustment should be used only when sensitivity at ankle level needs to be increased.
7.4.1 PROCEDURE:
• Disconnect the unit from AC power source (switch off battery back-up module, if installed);
• Open access door of detection unit;
• Remove the three (3) screws that hold the controller cover:
• Move jumpers as shown in the diagram on Figure 7.4.1 to achieve the required level of boost
(all jumpers must be set to the same level);
• Replace cover and reconnect power;
• Test unit to assure desired performance level.
