1 Overview

1.1 Introduction

ZK-D1090 metal-detector is a walk-through metal-detector that is used for security

screening at access points in the prisons, courthouses, and train stations.

Metal-detectors are highly sensitive to magnetic metals and have a high detection

capability, with less ability to detect non-magnetic metals. They are used to detect

the concealed metal weapons on a person’s body. It offers high-speed detection

capability. It can detect large metal objects like knives and guns. Its screening

capacity is very large when compared to hand-held metal detectors.

Feature

 Up to 9 detection zones and 500 sensitivity levels allow precise contraband

detection.

 Accurate detection of a wide range of contrabands.

 Clear threat indication with synchronous sound alert and LED indicator.

 Displays the number of pedestrians passed and alarm count accurately.

 Automatic setting of sensitivity and channel.

 Simple installation and use.

3 Installation Setup

3.1 Safety Precautions

• Install the detector in a stable and smooth area. Make sure that the

detector is installed firmly in the selected area.

• It can be used for both indoor and outdoor purposes. If used outdoor,

cover it with a canopy to protect against rain.

• 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 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.

3.2 Instructions to Pedestrians

• A line must be drawn at 50cm away from the detector. The pedestrians

must pass through the detector one-by-one.

• Pedestrians should line up one-by-one to ensure the smooth operation of

the detector.

• Pedestrians should walk at a normal speed. They must not intentionally

form a crowd, rush, walk slowly, or crush the door panel.

• Before passing through the metal detector, the pedestrians must remove

all the carried metal objects (such as keys, mobile phone, watch, coins, etc.),

ZK-D1090 User Manual

Page | 14

and place it on the security chute or a table, and pick it up after the security

check.

• If the detector alarms when someone passes through, that means there

is/are some metal object(s) hidden in the body. The security guard can use

a hand-held metal detector to accurately detect the hidden position

according to the alarm zones.

3.3 Installation Site

The following section describes the requirements of the installation environment.

3.3.1 Stationary Metallic Items

The detector must be installed away at 50cm from the stationary metallic items

such as aluminum alloy/stainless-steel windows, doors, etc. to prevent false alarms

and affecting the sensitivity of the detector.

3.3.2 Portable Metallic Items

The portable metallic objects must be kept away at 2 meters from the detector to

avoid false alarms.

3.3.3 Floor Vibration

The installation floor must be flat and fixed to avoid false alarm from the movement

of the people walking through the detector.

3.3.4 Electromagnetic Radiation and Interference

Since the detector uses Bilateral receiver technology, the detector must be installed

away at a distance of at least 1 meter from the sources of electromagnetic radiation

or electromagnetic interference. The parameters that define the distance are

determined by the installation environment and the parameters vary for different

installation environments.

The sources of electromagnetic radiation and electromagnetic interference are

given below:

ZK-D1090 User Manual

Page | 15

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.

3.3.5 Parallel Installation

When two detectors are installed parallel to each other, the distance between two

detectors must be greater than 50cm. When three detectors are installed parallel to

each other, the distance between each detector must be greater than 80cm. They

must operate at a different frequency to avoid interference. The distance varies

according to the actual working environment, it is not recommended to mount

three detectors in parallel, the frequency can be adjusted according to the

environment.

3.4 Installation Steps

Make sure that the device is installed as per the following installation instructions. If

you want to open the chassis, you should contact the agent for permission.

Otherwise, you will bear any consequence resulting from your actions.

You can preset the metal size, by excluding the false alarm of coins, keys, jewelry,

belt buckle, etc.

Digital Pulse Technology: Digital signal processing and filtering system in the

detector has excellent anti-interference ability.

Count Statistics: The detector displays the number of pedestrians passed and Alarm

count accurately.

Harmless: The detector is harmless to heart pacemakers, pregnant women,

magnetic floppy disks, recording tapes, etc.

Easy to install: The detector has an integrated design and it can be effortlessly

installed or disassembled in 15 minutes.

6 Detection Zones

The detector can detect a wide range of threat objects/weapons composed of

magnetic, non-magnetic metals and alloys.

Chassis Panel: The screen shows the number of people passing the detector and

the number of alarms.

Alarm Zones:

3-zone Mode 6-zone Mode 9-zone Mode

There are two unique sets of precise positioning LEDs evenly distributed on the

door panels. If the detected metal object reaches or exceeds the preset value, the

red LED glows and an alarm will be triggered. If there are multiple alarm targets, the

LED of each target location will glow with alarm.

ZK-D1090 User Manual

Page | 20

Infrared Sensor

After connecting the power supply, the metal detector starts to work. When there is

no person or object passes through the detector, the infrared sensors can

effectively stop alarming to avoid false alarms. It also helps to maintain an accurate

count of pedestrians and alarms.

6.1 Adjustment of Detection Zone’s Sensitivity

1. The device must be in a stable position to achieve the best detection effect

(refer 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 not shaking after one

minute.

b) The device should not alarm when the testing person did not carry any

metal items while walking through the detector.

2. You can exclude the small portable metal objects such as rings, key, belt

buckle, shoes, and so on, by following the steps given below:

a) Choose a small metal as a sample. Increase the sensitivity, so that when

the testing person carries the sample and pass through the detector, and

it would alarm.

b) Decrease the sensitivity a little, carry the sample, and pass through the

detector again. If it still alarms, once again reduce the sensitivity, 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 relative zone. After implementing the above adjustments, the

metal smaller than the sample will not alarm, but the metal objects bigger than the

sample can be detected accurately.

Troubleshooting

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 a and b are OK, replace the infrared sensor.

What to do if the detector gives a false alarm?

a) If the device gives false alarms frequently after installation, perform the

following steps:

• 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.

• Make sure that the installation location is stable and free from physical

movements.

b) If the false alarm is not caused by the environment, reduce the sensitivity level

of all zones.

c) Change the frequency.

d) Change the installation location.
