2.3 Placement Considerations
- Place the detector on a stable, level surface.
- Ensure sufficient clearance around the archway for smooth pedestrian flow.
- Position away from large metal objects or other electronic devices that could cause interference. The anti-interference technology helps maintain stable detection near electronics.
- Suitable for both indoor and outdoor use, but protect from direct heavy rain if used outdoors for extended periods.
2.4 Power Connection
Connect the power adapter to the detector and then to a standard electrical outlet (AC 100-240V, 50/60Hz). The detector operates on DC 12V/5A.
3. Operating Instructions
Familiarize yourself with the control panel and detection zones for effective operation.
3.1 Control Panel Overview
The detector features a digital tube display for settings and status indicators. The control panel allows for sensitivity adjustments and alarm management.

Figure 3: Control panel and key detection features.
3.2 Powering On/Off
- To power on, connect the device to a power source. The system will perform a self-diagnostic check.
- To power off, disconnect the power source.
3.3 Sensitivity Adjustment
The MD50018Z offers 2000 levels of sensitivity. Use the control panel buttons (e.g., "ENTER", "+", "-") to navigate and adjust the sensitivity settings. Higher sensitivity detects smaller metallic objects, while lower sensitivity reduces false alarms from minor items.
3.4 Understanding Detection Zones
The detector is divided into 18 independent detection zones, allowing for precise localization of metallic objects on a person. When an object is detected, the corresponding zone on the LED display will illuminate.

Figure 4: Diagram illustrating the 18 detection zones on the walk-through metal detector.
3.5 Alarm System and People Counter
- Audible and Visual Alarms: Upon detection, the system triggers clear audible alarms and illuminates the side LED bars to indicate the zone and intensity of the detected metal.
- People Counter: The integrated counter tracks the total number of visitors and the total number of alarms, providing useful data for security management.
3.6 Tamper-Proof Settings
The detector includes a password protection feature to prevent unauthorized changes to settings. Refer to the control panel instructions for setting and changing the password.
4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your metal detector.
4.1 Cleaning
- Wipe down the exterior surfaces with a soft, damp cloth.
- Avoid using abrasive cleaners or solvents, as these can damage the finish and electronic components.
- Ensure the LED display and sensor areas are kept clean for accurate readings.
4.2 Safety and Durability
The MD50018Z is constructed with durable door panels and an aluminum alloy crossbeam and uprights, designed for long-term use. It is certified safe for humans and the environment, emitting no radiation, making it suitable for pregnant women and pacemaker users.
