Getting a DFMD is a smart investment but it’s only as effective as its setup and care. Proper DFMD installation and maintenance ensures accuracy, uptime, and long-term durability. Whether you’re securing a mall or airport, these 5 essential tips will help keep your walkthrough metal detector performing at its best.
1. DFMD Installation in a Stable, Non Metallic Area
- Avoid placing your DFMD near metal walls or reinforced structures, as they can cause interference.
- Place the unit on a level, vibration free floor at the building’s entrance or security checkpoint.
- Ensure the environment is dry and well ventilated to prevent sensor degradation.
2. Perform Initial Calibration After Installation
- Run an auto calibration sequence using built in software (most modern DFMDs have this feature).
- Walk through the detector with known metal objects at various zones to verify sensitivity.
- Use the default factory settings as a baseline and tweak based on your site’s requirements.
3. Adjust Sensitivity to Match Foot Traffic and Risk Level
- High risk areas like airports may require 80–99 sensitivity.
- Public spaces like malls and cinemas may only need 40–60.
- Avoid overly high sensitivity, which may result in false alarms from belt buckles or phones.
4. Maintain Your DFMD Weekly or Monthly
- Clean dust or debris from sensor panels and base pads.
- Check power cables, LEDs, and audio alarms for wear or malfunctions.
- Run diagnostics using the remote control panel or built-in diagnostics module.
5. Secure the DFMD with Password Protection
- Use the password protection feature to prevent unauthorized access to sensitivity settings or diagnostic controls.
- Regularly update passwords and train authorized security staff on operational use.
Your DFMD installation and maintenance strategy is just as important as choosing the right model. With proper setup, periodic calibration, and consistent upkeep, you’ll enjoy accurate threat detection and long term performance from your system.
