The Winkhaus keyTec RPS cylinder is suitable for mechanical master systems. With it, it is possible to create a locking logic according to the company's needs. The idea of the master system is to reduce the number of keys in the company to an optimal level without compromising its security. Most often, there is a master key that is used by the owner of the company and with which any room in the building can be accessed. At the same time, with a special monitoring procedure, the security can take over the same in emergency situations (flood, fire...) in order to react in a timely manner, and at the same time be sure that they will open the necessary door with that key. The floor manager can go through the necessary corridors and open only the floor he is in charge of. The employee also goes through all the corridors to the entrance to the floor where he works, enters through them and opens only his office. This is just one of the scenarios, in agreement with the client, the system is adapted to each client separately without any compromises.
