Metal detection security doors are widely used in crowded places such as stations, subways, airports, and government units. Their main function is to detect whether human bodies or objects carry metal objects. Although the installation of metal detection security doors is very simple, the correct installation of security doors is the first This contact is not easy. So how to adjust the disturbed metal detection security door?

Mechanical interference

Revolving door: The distance between the detector and the revolving door should be kept at 1000 mm. Make sure the revolving door opens outward. If there are two doors, the probe door should be installed on one of the doors. If it is a metal door, we recommend locking the other door. If it is a metal door, we recommend cutting off a corner of the metal door frame to isolate the metal ring. After installation, the revolving door turns back and forth to check the installation effect of the safety door.

Electronic interference

There are many things that cause electronic interference to security gates, such as elevators, engines, televisions, computers, telephone lines, mobile phones, etc. These objects should be kept away from the security gate, if there is continuous serious interference, please consult your dealer.

1. If it is to be used on the grid, the minimum distance between the two doors should be kept at more than 700 mm to avoid mutual interference between the security doors.

2, if the security gate is installed too close to the roadside, large vehicles entering and exiting may affect their normal work. Therefore, we recommend to keep the security door away from the roadside as much as possible during installation.

3. In order to reduce the false alarm rate, we must find out the reasons that affect the false alarm; because the security door x-ray machine uses the two-way transceiver technology, therefore, any electromagnetic source and electromagnetic radiation source should not be close to the security door, the interference is controlled by the electronic Box, radio frequency equipment, electronic computer and peripheral equipment, video monitor, high-power generator, AC power line, thyristor control circuit (high-power switching power supply, inverter welding machine) and old electronic filled fluorescent lamp work at the same time. Floor vibration, outdoor wind, and slight swing of the door body will affect the normal operation of the safety door. Keeping away from large metal objects, it is necessary to pay attention to the impact of the rolling gate, iron security door and gate mesh iron door on the security door to avoid false alarms.
