MEDICAL SAFETY

Garrett Metal Detectors makes every effort to ensure its products are safe for use. Extensive research by Garrett
has produced no information which would indicate that its products have any adverse effects on medical
implants, pregnancy, recording media or magnetic strips. Garrett cooperates with medical device manufactur­ers and agencies such as the United States Food and Drug Administration and Health Canada as a means of
assuring product safety. The electromagnetic fields produced by Garrett products are similar to those encoun­tered in the daily environment and meet U.S. and International standards for electromagnetic emissions.

Garrett recognizes that certain medical devices may have additional requirements which may require special
care. Any recommendations or directives issued by personal physicians or medical device manufacturers
should be followed. If, for any reason, (e.g. doctors orders, etc.), a patron objects to being scanned with a metal
detector, it is recommended that alternative procedures be used.

The following should be considered when developing a security checkpoint screening plan:

• Traffic Flow - Traffic flow should remain unobstructed as a means of minimizing the time a per-

son remains within the archway of a walk-through metal detector.

• Alternative Screening - Alternative screening methods such as scanning with a hand held

metal detector, hand searching or denial of access should be clearly defined in checkpoint
screening procedures as approved alternatives to screening with the walk-through metal detec­tor.

• Personnel Training - Security screening personnel should be instructed in the care of persons

with special medical needs and use of alternative screening methods that meet the requirements
of medical practitioners or medical device manufacturers.

1. MT 5500 GENERAL DESCRIPTION

The Garrett MT 5500 Walk-Through Metal Detector features multi-dimensional, microprocessor-controlled cir-

cuitry and LCD presentation of all calibrating and operating information. It is capable of remote operation and

monitoring, when required, and is designed to be easily portable. The unit can be operated on battery power

alone through use of an optional battery pack, which further enhances its portability.

The detector is manufactured by Garrett Metal Detectors in Garland, Texas.

The MT 5500 uses microprocessors in both its detection and control circuitry. These integrated circuits contain

the necessary elements of a small digital computer and are preprogrammed to provide discrimination capabili-

ties that enable the MT 5500 to optimally detect weapons and other devices made of metal. At the same time,

multi-dimensional detecting informs the operator whether a target being detected is on the left, right or

center/balance of the detector. Multi-dimensional detecting increases throughput dramatically by minimizing

false alarms and the “down-times” that results from them.

The microprocessors permit the MT 5500 to be considerably more sophisticated in its programming and pro-

vide greater flexibility in the selectivity of the metals it detects. The detector also features excellent sensitivity,

stability and noise rejection. All electronics are built into an overhead panel of the unit to eliminate problems of

logistics and reliability often associated with a cable-connected console.

The LCD display on the face of the detector's overhead panel, backlit for easy viewing, reports information con-

cerning the unit’s calibration and operation. This includes program data, sensitivity settings, operator settings

and fault indication. Two bright LED bar graphs, easily visible from a distance, give an indication of the strength

of the alarm and report whether its is on the left or right side of the unit or in the middle. The audible alarm has

three distinct tones to reflect this positional detecting. Separate lights indicate ready and alarm conditions. All

regulation and control functions are “self-prompting” with necessary commands shown automatically on the

LCD. The unit also reports a traffic count on its LCD.

The system offers highly flexible capabilities with a continuously variable range of programs, including sever-

al that have been designed for specific purposes. Programs are regulated by state of the art touchpads and

reported visually on the LCD. Improved security of the unit’s detection settings comes from an advanced sys-

tem of access codes. Two levels of codes eliminate the need for bothersome keys for locked doors or other

protective devices, while the MT 5500 circuitry provides precise accuracy of calibration. Access Code #1 is

used by supervisors for selecting programs and sensitivity with Access Code #2 designed for initial set up and

overall control. All settings are encoded by touchpads and remembered in any resettable memory. Security of

the unit’s calibration settings is further protected by a non-resettable sequence code that allows supervisors to

MT 5500

User Manual

keep a log of all changes that are ever made as well as any unsuccessful attempts to change them. In addi-

tion, a tamper indication reports any unauthorized or incorrect attempts at access.

A complete and automatic self-diagnostic program is carried out by the MT 5500 each time the Operate touch-

pad is pressed. In addition, the detector utilizes self-testing circuitry that continuously monitors the critical func-

tions of the detector, reporting automatically the failure of any element that would affect operation of the unit.

2. CONTROLS & MODULES

2.1 DISPLAY PANEL

2.1.1 LED BAR GRAPHS

The two LED displays located on the Control Panel indicate the detection intensity which is based
on the amount and composition of metallic objects passing through the unit.

2.1.2 READY LIGHT

This green light appears when power is turned on and the unit is ready to operate. The light will also
indicate when an individual inspection has been completed by the unit and it is ready to accept the
next person. Operators should make certain the green light is visible before any individual is permit­ted to pass through the detector.

2.1.3 LCD PANEL

Large alpha/numeric LCD, backlit for easy viewing, reports all operating, setup and diagnostic infor­mation of the unit. Because the unit is designed to be “user-friendly”, all regulation and control func­tions are self-prompting with necessary commands shown on the LCD display.

2.1.4 ALARM LIGHTS

These red lights appear when the unit detects a targeted amount of metal on an individual, accord­ing to specifications of the Program and Sensitivity levels that have been selected. If only one light
appears, it will indicate which side (left or right) of the passageway the largest target can be found.
When both lights appear, the target(s) are centered, or balanced, within the archway. The lights will
appear even when Audio volume has been turned OFF. Operators should be instructed to respond
to all alarms. For any detector to be effective in a security system it is absolutely necessary that the
cause of EVERY ALARM be determined.

2.2 TOUCHPADS

Eight touchpads on the overhead Control Panel perform all control functions:

2.2.1 ON / OPERATE / TEST

Whenever this touchpad is pressed, the MT 5500 activates all circuits, initiates a self-diagnosis pro­gram and places the unit in the Operate Mode. This diagnostic program for instant fault detection
can be activated at any time by touching the OPERATE touchpad. If any faults are ever found, they
will be immediately reported on the LCD display. (See Section 4).

2.2.2 OFF

When this touchpad is pressed, the unit is turned OFF. All information and settings are stored in
memory and the unit is ready to be returned to full operation instantly when the OPERATE touch­pad is pressed.

2.2.3 COUNTER

When this touchpad is pressed, the traffic count is displayed on the LCD display. Pressing and hold­ing this touchpad for ten (10) seconds causes the counter to return to zero (0). Whenever the LCD
is displaying information other than the current traffic count, pressing this touchpad will cause the
count to appear along with the Sequence Number of changes that have been made to
Program/Sensitivity settings. CT (Number) and SEQ (Number) will appear. Each time the
Program/Sensitivity Mode (ACCESS touchpad) is accessed, the Sequence Code that appears on
the LCD will be advanced one number. It is recommended that a written notation be made on the
Operations Worksheet (see Section 11.1) whenever this code is accessed, explaining reasons for
the access. If the ACCESS touchpad has been pressed and an improper access code has been
entered, a * will appear before the sequence number (SEQ *37). This indicates that an unsuccess­ful (unauthorized) attempt has been made to gain access to the Program/Sensitivity setting.

2.2.4 VOLUME

When this touchpad is pressed, the volume level of the unit’s audible alarm will be shown on the
LCD display and the actual volume of the alarm will be heard. The + and - touchpads can be used
by operators to raise or lower the volume. Press OPERATE to return to the operate mode.

2.2.5 + AND -

These touchpads will be used to increase or decrease various numerical settings and for certain ON
/ OFF functions.

2.2.6 PROGRAM

When this touchpad is pressed, the settings for Program and Sensitivity will appear on the LCD dis­play.

SPECIAL NOTE: The above touchpad functions will be available to operators of the detector at all
times. Additional functions such as program and sensitivity settings and other adjustments neces­sary only at installation time may be selected by pressing the ACCESS touchpad and entering a
security code.

2.2.7 ACCESS

The ACCESS touchpad will be used only by supervisory management personnel. It permits chang­ing the Program and Sensitivity codes and also is used to control such functions as synchronization
of multiple units, pulse frequency, tone, etc. (See Section 5.3). The unit further protects security of
control settings by maintaining a non-resettable sequence code that indicates any attempt at seek­ing access to the settings. When this touchpad is pressed, audio of the system will “chirp” and
ENTER CODE will be displayed on the LCD, prompting the operator to enter an access code. If no
attempt is made to enter a code, the unit will continue chirping for ten (10) seconds and return to
Operate Mode. If the operator enters an incorrect code, audio will sound a Tamper Alarm and
ACCESS DENIED will appear on the LCD for five (5) seconds. An asterisk (*) will appear on the
Sequence Counter indicating that an unsuccessful attempt has been made to access the Installation
or Program/Sensitivity Modes of the unit.

Operator’s should never touch this control. If an operator should inadvertently press the ACCESS
touchpad, no further action should be taken and the unit will return automatically to the Operate
Mode in about ten (10) seconds.

2.3 INTERNAL MODULES

2.3.1 CONTROLLER MODULE

This module (in the center) contains all circuit boards necessary for operation of the detector. Two
cables (A and B) that connect this module to the side panels are to be plugged into the connectors

3. INSTALLATION INSTRUCTIONS

3.1 SITE SELECTION

The Garrett MT 5500 should be located on a level, stable floor with no large metal items within three
(3) feet. Any nearby large metallic object can interfere with operation of the detector. Moving metal­lic objects, such as an escalator or revolving door, close to the detector can cause false alarms. Such
alarms can also be caused by electrical interference from radio telephones, television monitors, pow­erful electronic motors and transformers, power cables and control circuits. A stabilizer base (PN
1603900 - not included) is required to stabilize the detector and help prevent the unit from being
pushed over. Be sure to follow installation directions carefully. (See Section 11.7).

Garrett’s special built-in circuitry is designed to suppress much of this electronic noise, especially X­ray monitor horizontal synchronization signals and closed circuit television. Multiple frequencies per­mit several MT 5500 units to operate simultaneously, in close proximity.

For information concerning the operation of multiple units, see Section 11.3.

The site for a MT 5500 should be selected with requirements for its pedestrian traffic and use in mind;
i.e. space for waiting lines, operators and areas for hand-scanning. Locate the archway where it will
not be subject to rain, mist or condensation. Protect the power cable from pedestrian as well as
vehicular traffic.

3.2 ASSEMBLY
