1 Overview
1.1 Introduction
ZK-D4330 Walk Through Metal Detector, also known as Security Door, is a fixed detection
device used primarily for inspecting the metal items concealed on the body. When a person
passes through the device carrying metal object(s) larger than the preset size, the device will
immediately generate alarms, and display the alarm location as well. The people detected
with metal need to be checked by the security guard thoroughly and the prohibited metal
articles should be ceased, if found. It is highly sensitive to magnetic metals and have a
strong detection capability, but are weak in detecting non-magnetic metals.
This device features faster induction, more accurate detection, higher sensitivity level, and
stronger interference immunity.

3 Installation
3.1 Safety Precautions
• Install the detector in a flat and stable area. Make sure that the detector is installed
firmly in the selected area.
• Before installation, make sure the left and right door panels are placed at the
corresponding location. Avoid high temperatures and wet environments.
• Wait for 1 minute for the self-diagnosis of the detector when it starts. Do not touch the
detector during a security check to avoid any false alarm.
• Install the detector away from radio-frequency devices to avoid interference. Make
sure that there is no large metal object or strong magnetic field around the detector
for at least 2 meters.
• Do not hit the detector hardly, as it may cause false alarms.
• Do not disassemble the unit without the guidance of a professional technician.
• Each device has a warranty card, with which users can have their devices maintained
or repaired free of charge within the warranty period.
If you want to install in semi-outdoor, please use it as follows:
1. Please select this model semi-outdoor configuration.
2. No soaking of device in water, prohibit prolonged contact with rainwater(no more
than 3 minutes).
3. Device can be used continuously for three months in a semi-outdoor dry
environment (humidity less than 60%), and for seven days in a semi-outdoor rainy or
humid environment.
3.2 Instructions for the Pedestrians
• A line must be drawn at a distance of 50 cm away from the detector. And the
pedestrians must cross the line one-by-one while passing through the detector to
ensure a smooth operation.
• Pedestrians should walk at a normal speed. They must not deliberately form a crowd,
rush, walk slowly, or damage the door panel.
• Before passing through the metal detector, the pedestrians must remove all the metal
objects he/she is carrying (such as keys, mobile phone, watch, coins, etc.), and place it

ZK-D4330 User Manual
Copyright©2024 ZKTECO CO., LTD. All rights reserved.
Page | 10
on the security chute or a table, and pick it up after the security check.
• If the detector alarms when someone passes through indicates that there is/are some
metal object(s) concealed in his/her body. The security guard can use a hand-held
metal detector to precisely detect the metals position according to the alarm zones.
3.3 Installation Site
The following section describes the requirements of the installation environment.
3.3.1 Metallic Items
The detector must be installed at a distance of 1 m from the fixed metallic items such as
aluminum alloy/stainless-steel windows, doors, etc. to prevent false alarms which may
affect the sensitivity of the detector. Also, the portable metallic objects must be kept at
least 2 m away from the detector to avoid false alarms.
3.3.2 Floor
The installation floor must be flat and rigid to avoid any shake from the movement of the
people walking through the detector.
3.3.3 Electromagnetic Radiation and Interference
Since the detector uses Bilateral Receiver technology, it must be installed at a distance of
at least 1 m away from the sources of electromagnetic radiation or electromagnetic
interference as it may affect the sensitivity of the detector. The parameters that define the
distance are determined by the installation environment and it varies for different
installation environments.
The sources of electromagnetic radiation and electromagnetic interference can be
Electrical Control Box, Radiofrequency equipment, Interphone, High Power Motor, Power
Transformer, Ac Power Lines, Thyristor Control Circuit (High Power Switching Power Supply,
Inverter Welder), Engine, Motor, etc.
3.3.4 Parallel Installation
No. of detectors installed parallelly Distance between the detectors
2 > 10 cm
3 > 30 cm
4 or more > 50 cm

ZK-D4330 User Manual

7 Detection Zones
A. 7'' Touch screen and control buttons
B. Detection zone display
There are four unique sets of precise
positioning LEDs evenly distributed on the
door panels, showing the status of 33
detection zones, as shown on the right. The
zone indicators can be turned on or off. If the
walkthrough metal detector detects metals of
the size that reach or exceed the preset value,
the alarm indicator of the detection zone turns
on, and an alarm is generated.
(No alarm is generated if the device is in mute
state.)
C. Infrared sensor
After being connected to a power supply, the
metal detector starts to work. When no person
or object passing through the device, the
infrared sensors stop alarming to avoid false
alarm and accurately count passengers and
alarm times.
7.1 Adjustment of Detection Zone’s Sensitivity
1. The device must be in a firm and stable position to achieve the best detection result
(refer to Installation Site
). To check whether the device is in a stable state, perform the
following steps:
a) Power on the detector and check whether it is shaking or not, after one minute.
b) The device should not alarm when the testing person is not carrying any metal
items while walking through the detector.
2. You can exclude the small portable metal objects from being scanned such as rings,
key, belt buckle, shoes, and so on, by following the steps given below :
A
B
B
C
C

ZK-D4330 User Manual

a) Choose a small metal as a sample. Increase the sensitivity, so that the device
alarms when the testing person carries the sample and pass through the
detector.
b) You need to decrease the sensitivity a little and pass through the detector again
carrying the sample. If it still alarms, you need to reduce the sensitivity once again,
until the device does not alarm when the sample is passed through.
Note: If you want to decrease the sensitivity in a certain zone, you must only adjust the
sensitivity of the related zone. After implementing the above adjustments, the metal smaller
than the sample will not generate an alarm, but the metal objects bigger than the sample
can be detected accurately.
8 Operational Procedure

Troubleshooting
What to do if an error is prompted during the auto testing?
a) When the message "EFT ZONE ERROR RIGHT ZONE ERROR" is prompted during the
auto testing, please pay attention to whether the left and right signal cable plugs are
inserted tightly.
b) When it prompts "The infrared receiving error", please check whether the left and right
signal wires of the door panel are connected properly, whether the infrared sensors
are connected properly, and whether the two sets of infrared sensors are blocked.
What to do if the Sensor could not count?
a) Check whether the probe cables are connected firmly with the door panels.
b) Check whether there is any infrared interference beside the device, such as infrared
surveillance system, infrared remote control, outdoor sunlight, etc.
c) If both, condition a and condition b are OK, then the issue is with the infrared sensor
and need to be replaced.
What to do if the detector gives a false alarm?
If the device gives false alarms frequently after installation, perform the following steps:
a) Firstly, check the installation environment. Make sure there are no movable or
stationary large metal objects around 1.5 meters from the detector. If there is any
metal object, try to place the device away from the large metal objects.
b) Make sure that the installation location is firm and stable and free from physical
movements. If not, change the installation location.
c) If the false alarm is not caused by environmental interference, then reduce the
sensitivity level of all zones.
d) Change the frequency.
