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 closer, and the “exit” button » inside the office.
How does it work single door access control system with electromagnetic lock? Firstly: those who do not have access will not get into the office / office on their own without using a 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 by 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 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 the force of its separation. This indicator may vary from 150 to 1200 kg at break, despite the fact that the average person is not able to create efforts of more than 120 kg. Therefore, connecting an 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 front door, due to safety reasons, must be produced with a minimum lift-off value from 600 kg.
EMZ are different:
- type of lock;
- type of control.
These two species are further subdivided into subspecies. So, in case of locking, they are sliding and holding back.
By type of management: with hall sensors(require additional food) and elements of the reed switch(no need for constant power supply).
EMP 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 its varnishing. This method is not the best, because with temperature changes 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 cause minimal harm.
- If nickel is used for protection, then various kinds of repair work can be completely avoided.
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.
