7. SUPERVISOR RESPONSIBILITIES
7.1 CALIBRATION
Calibration settings of walk-through metal detectors are dependent upon individual security screening
requirements and, therefore, . 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.
NOTE: Types of Audio Alarms
Understanding the audio alarms the CS 5000 can sound will enable both supervisors and operators to
understand the detector better and help assure totally accurate screening. Each of three unique audio
alarms is designed to call the operator’s attention to current circumstances:
1. Set-up Alarm: Produces two short beeps as a person is walking through the unit. This alarm indi-
cates that the metal detector is in a set-up mode and is not ready for operation. Wait for green READY
light (press OPERATE touchpad, if necessary). Person(s) who triggered the Set-up Alarm must pass
through the unit again.
2. Standard Alarm: Occurs when red ALARM light appears and a targeted amount of metal is
detected according to Program and Sensitivity levels.
Occurs when a large metal mass, such as a wheelchair, furniture or large
metal container is moved through or near the CS 5000. The large amount of metal has
saturated the detector’s receiver circuits and the warble alarm is an indicator that the operator should
correct the situation before allowing anyone to pass through the metal detector.
Calibration and verification can be performed with an Operational Test Piece (OTP), which is an object
similar in size, shape and composition to the smallest forbidden target. Once the walk-through metal
detector is properly calibrated, an OTP may be used to simulate the forbidden objects and verify cali-
bration on a regular basis. The OTP thereby offers a generally accepted means of verifying calibration
without the necessity of having on hand actual weapons at the screening station on a daily basis.
7.2 FAA TEST PIECE
Garrett manufactures an 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 prop-
erly calibrated and is detecting metal. The OTP has been designed to serve as a basic instrument 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 orientations.
The number of repetitions required at each level with corresponding successful alarms should be
established, and this testing system should be adhered to consistently.
