The airlock is in the form of a cabin made of armored materials. It is made up of two partitions which together relieve an exterior door and an interior door.

The airlock delimits a safety volume that must be crossed to enter the building. The two doors are slaved to each other, which ensures continuity of the security perimeter. Its installation at the entrance to the building allows, by creating a visible and therefore dissuasive obstacle, to obtain a very good safety approach.

All of the information necessary for the operation of the airlock is generated by electronic management thanks to a PLC which receives the various sensors as inputs (call, door status, etc.) and which controls the various actuators (locks, indicator lights, etc.) as inputs. … ..).

The doors are locked by electric CORNI type locks. In addition to conventional operation, these locks benefit from a Fire Safety application, allowing immediate opening in the event of an alarm. A control panel, in conjunction with the airlock management, makes it possible to choose different operating modes according to the requirements linked to the fluctuation in traffic and the variation in the level of security required.

The passage of people in the airlock is carried out according to procedures which call for various and various controls in order to:
Dissuade potential aggressors from taking action;
Prohibit access to the site to people at risk;
Oppose mechanical resistance to aggressors no longer hiding their intentions
