Metal detectors 02PN7, 02PN8 and HI-PE / CF are designed to be built in cabins (sluices) equipped with two revolving doors, entrance and exit.

The principle of operation of such a system is as follows: before the inspection begins, the entrance door opens, the controlled person enters the cabin. Then the entrance door is closed, scanning is performed. In the case of positive verification, the exit door opens and the controlled person can enter the protected facility. Otherwise, if a dangerous object is detected, a person must leave the cabin through the entrance door, so he cannot get into the area of ​​the controlled object. Such a system is ideal for unattended access control, as it does not require the involvement of a supervisor. Metal detectors 02PN7, 02PN8 and HI-PE / CF can have alloys in the form of columns as well as panels. The first two are simpler models, the last, HI-PE / CF is characterized by much greater possibilities of discrimination, i.e. distinction between dangerous items such as firearms and personal items such as keys, coins, watches
