7. SUPERVISOR RESPONSIBILITIES

7.1 CALIBRATION

Calibration settings of walk-through metal detectors are dependent upon individual

security screening 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.

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

indicates 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.

3. Warble Alarm: 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 ver-

ify calibration 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

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
