The problem of restricting access to a separate office, inside a large office, has a simple technical solution - just install outside cabinet, a reader for cards / keys, a controller (control unit) with a power supply, and an electromagnetic lock on the door with a closer, and an “exit” button inside the cabinet.

How does it work single door access control system With electromagnetic lock? Firstly: those who do not have access will not be able to get into the office/office on their own without using a crowbar and other tools. Secondly: the remaining small group persons who have access and, accordingly, have electronic keys or access cards, can easily open the door by presenting their card to the reader. When the card is brought to the reader, a special controller checks whether it is written into memory and if so, the electromagnetic lock turns off for a few seconds, at which point the system emits a sound signal so that the person can orient himself and open the door in time.

The most important characteristic of an electromagnetic device is its pull-out force. This indicator may vary from 150 to 1200 kg tensile strength, despite the fact that the usual average person not capable of creating forces greater than 120 kg. Therefore, connecting an electromagnetic lock to metal door or any other is a good solution.

Magnets with the weakest adhesion are generally used for interior doors. Installing an electromagnetic lock on the entrance door, due to safety reasons, should be carried out with a minimum lift-off value from 600 kg.

EMZ differ:

• type of locking;
• type of control.

These two species are in turn divided into subspecies. So, in case of locking they are sliding And holding.

By type of control: with Hall sensors(require additional power supply) and Reed switch elements(no need to supply constant energy).

EMZ protection methods

To ensure maximum lock durability, work surface it is necessary to apply a certain protective coating.

The following methods exist:

• Most economical option The preservation of the castle is its varnishing. This method is not the best, since with temperature changes and frequent precipitation, the entire varnished layer comes off, resulting in the formation of rust and corrosion.
• When galvanizing the surface, the service life increases significantly, since external factors cause minimal harm.
• If you use nickel for protection, then you can completely avoid various types of repair work.

When installing electromagnetic locks and using them, there are some tricks and tricks that in the future will help make the operation as complete as possible, without damage and other unpleasant moments.
