CS 5000User Manual© 2009 GARRETT METAL DETECTORS 20 PN 1530100 REV H7. SUPERVISOR RESPONSIBILITIES7.1 CALIBRATIONCalibration settings of walk-through metal detectors are dependent upon individual security screeningrequirements and, therefore, must be the responsibility of the screening installation. Program andSensitivity settings should be established at a level that permits the detector to detect all forbiddenobjects that can be reasonably expected to appear at a particular screening station. Actual forbiddenobjects should be used as targets for initial calibration.NOTE: Types of Audio AlarmsUnderstanding the audio alarms the CS 5000 can sound will enable both supervisors and operators tounderstand the detector better and help assure totally accurate screening. Each of three unique audioalarms 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 READYlight (press OPERATE touchpad, if necessary). Person(s) who triggered the Set-up Alarm must passthrough the unit again.2. Standard Alarm: Occurs when red ALARM light appears and a targeted amount of metal isdetected according to Program and Sensitivity levels.3. Warble Alarm: Occurs when a large metal mass, such as a wheelchair, furniture or largemetal container is moved through or near the CS 5000. The large amount of metal hassaturated the detector’s receiver circuits and the warble alarm is an indicator that the operator shouldcorrect 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 objectsimilar in size, shape and composition to the smallest forbidden target. Once the walk-through metaldetector 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 calibrationwithout the necessity of having on hand actual weapons at the screening station on a daily basis.7.2 FAA TEST PIECEGarrett 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 beconsidered.7.3 TESTINGIt is imperative that a standard test program be developed for walk-through metal detectors within asecurity 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 foruse in such a test program.A test program should include passing the OTP and/or other objects through each metal detector atvarious 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 beestablished, and this testing system should be adhered to consistently.
