Definitions
Please find our explainations of some special nouns used in this manual.
WTMD– means walk through metal detector
Sensitivity– It is a parameter used to define the size of a metal object that
generates an alarm.The higher the sensitivity, the smaller the volume of
detectable metal objects. and vice versa.
Useless alarm– alarm caused by harmless metal articles carried by personnel
passing through security gates.
False alarm-alarm caused by causes other than metal objects (e.g. electronic
interference).Alarms caused by metal objects (useless or useful) are not false
alarms.
Alarm rate, percentage of the number of alerts caused by metal objects.
Throughput, The maximum number of people allowed to pass within a
specified period of time without affecting the detection performance
Calibration, According to the requirements of the operation site, in order to
achieve the best performance, adopt the steps of setting the parameters.
Use side-by-side– If multiple security doors are used side by side, it is
suggested that there should be a certain distance between the doors. Normally
0.4m-0.5m. To achieve the best detector effect.
Operation frequency, usually in places with more than two doors, the
magnetic fields of the doors interfere with each other.

accessories of the equipment, or the contents of this manual. Any changes are
not notified.
4. Brief Introduction
Specified Purpose
This equipment is used to detect all personnel carrying metal objects through
the security door, mainly for metal detection.
Typical application environments including:
Airport, port: passenger inspection
Court: visitor inspection
Jail: visitor inspection
Conference, public building, sports, entry control
Power plant, staff, visitors
Factory, Anti-theft to prevent the loss of raw materials
Hotels, restaurants, entertainment venues, visitors inspection.
If the equipment is used for purposes other than those described above, the
manufacturer will not be liable.
After a long-term experiment and research, the device adopts safe design and
existing knowledge, and operates according to instructions. It will not cause
health hazards to pregnant women and people wearing cardiac pacemakers.

Operational Principle
The operating principle is electromagnetic pulse magnetic field technology
Transmitter pulse can attenuate the eddy current of metal objects in the
sensitive area of the detection gate.
The eddy current induced by the receiver is sampled and processed by the
electronic component.
When the signal exceeds the alarm threshold, moving metal objects are
Sensed.

5. Installation
When planning to install a security gate site, there are several important
considerations. Only when these factors are taken into account, the best state
of detectors and the Maximum traffic at security checkpoints can be ensured.
To minimize the effect of different interference sources on the operation of
detection gates as much as possible, this is very important. When choosing
the installation site, please consider this suggestions.
Fixed metal
Fixed or immobile large metal objects should be at least 15 cm away from the
detection door. (Detection of large metal objects) . This has little effect on
sensitivity, but may cause the door to be affected by vibration.
Ground vibration
The ground should be flat with strong support to prevent vibration.Especially
when there is a metal structure vibrating under the ground, An unnecessary
alarm may be caused when a person passes through the detection door.

Moving metal objects
Large metal objects moving at outside of the detection door should be kept at a
distance of 0.5-2 m from the detection door, so as to avoid false alarm.
According to the size of the metal object, the distance between the moving
metal object and the detection door may be different.
Radiative electronic interference
The distance between the electronic interference source and the receiving coil
should be maximum. The recommended minimum distance is 0.5-4m.
However, the actual distance needs to be determined according to the specific
situation.For example, detection gates and interference sources that can move
with each other can directly find the best location.
Interference may include electronic control panels, radio devices and
computers, image displays, high-power motors and transformers, AC line,
transistor control circuit, flash fluorescent tube and arc welding equipment are
produced.
Conductive electronic interference
Connect the power cord to a circuit that is not connected to other heavy loads,
such as high-power motors, etc. They may cause greater power and voltage
shocks in the circuit.

6. Checkpoint Layout
In order to achieve maximize the flow of people, the layout of security
checkpoints should be carefully deployed before installing the equipment. In
addition to considering the mechanical and electronic interference factors at
the installation site, safety inspection should be properly organized and carried
out effectively. The functionality of checkpoints is largely affected by the
following factors:
Arrange the waiting queue of metal detection door so that only one person is in
the detection door at a time.
Searching for detected metal objects should not interfere with the normal
inspection operation of the detection door.
Inspection of hand luggage should be arranged to avoid false alarm.

If there is no security machine, the baggage should be checked manually.
7. Side-by-side Operation
Parallel operation refers to the operation of two or more detection doors close
to each other. When operating side by side, the through gate may interfere with
each other to some extent. The interference level depends on the distance
between the detection gates, their operating frequency and sensitivity.
The detection gates have different frequency choices, which can reduce the
interference of adjacent security gates and ensure that they can be applied
side by side. When operating the detector gates side by side, it is especially
recommended that the operating frequency be distinguished from each other,
and the sensitivity and distance be adjusted. The minimum distance between
side by side is 40 cm.

If two doors are working side by side. It is suggested to replace the working
frequence of
and . (If the working frequency of is 3, then the working
frequency of
is 8, it will be OK to stagger the frequency channel between
each other.)
