READY LIGHT
This green light appears when full power has been turned on and the unit is ready to detect. 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 individ-
ual is permitted to pass through the detector.
10.5
ALARM LIGHT
These red lights appear when the unit detects a targeted amount of metal on an individual, accord-
ing to specifications of the Program and Sensitivity levels that have been selected. If only one light
appear, 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.

TYPES OF AUDIO ALARMS
The MT 5500 has three types of alarms. Each of these unique alarms is designed to call the opera-
tor’s attention to current circumstances:
10.6.1
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
OPER-
ATE
touchpad, if necessary). Person(s) who triggered the Set-up Alarm must pass through the unit
again.
10.6.2
STANDARD ALARM
There are three different standard alarm tones. These tones indicate whether the target is on the
left side, right side or center / balanced within the archway. One of these alarms will sound when a
red ALARM light appears and a targeted amount of metal is detected according to Program and
Sensitivity levels.
10.6.3
WARBLE ALARM
Occurs when a large metal mass (a wheelchair) moves through or near the MT 5500. When a large
amount of metal saturates the detector’s receiver circuits the warble alarm indicates that the situa-
tion should be corrected before anyone passes through the detector.
10.7
BAR GRAPH
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.
10.8
TOUCHPADS
Eight touchpads on the overhead Control Panel perform all control functions.
10.8.1
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 when the OPERATE touchpad is
pressed. Operators should use all touchpads only as instructed by supervisors.
10.8.2
OPERATE
When this touchpad is pressed, the MT 5500 activates all circuits, initiates a self-diagnostic program
and places the unit in the Operate Mode within 10 seconds. This diagnostic program for instant fault
