The most important characteristic of an electromagnetic device is the force of its separation. This indicator can vary from 150 to 1200 kg at break, while the usual average person not able to create forces more than 120 kg. Therefore, connecting the electromagnetic lock to metal door or any other is a good solution.

The magnets with the weakest adhesion are usually used for interior doors. Installation of an electromagnetic lock on the entrance door, for safety reasons, must be produced with a minimum separation value from 600 kg.

EMRs differ:

• type of locking;
• type of control.

These two types are divided in turn into subspecies. So, in the case of locking, they are sliding and restraining.

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

EMZ protection methods

To ensure maximum durability of the lock, a certain protective coating must be applied to the work surface.

There are the following ways:

• The most economical option for preserving the castle is to varnish it. This method is not the best, since with temperature extremes and frequent precipitation, the entire varnished layer comes off, resulting in rust and corrosion.
• When the surface is galvanized, the service life is significantly increased, since external factors do a minimum of harm.
• If nickel is used for protection, then all kinds of repair work can be avoided altogether.

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

The task of restricting access to a separate office, inside a large office, has a simple technical solution - it is enough to install a card / key reader, a controller (control unit) with a power supply on the outside of the office, and put an electromagnetic lock on the door with a door closer, and a button "exit "Inside the cabinet.

How does it work one door access control system with an electromagnetic lock? Firstly: those who do not have access will not get into the office / office on their own without using crowbar and other tools. Secondly: the remaining, small group of people who have access and, accordingly, have electronic keys or access cards, easily open the door, bringing their card to the reader. When the card is brought to the reader, a special controller checks whether it is stored in memory and if so, the electromagnetic lock is turned off for a few seconds, the system at this moment issues sound signal so that a person can orientate himself and open the door in time.
