Electronic door locks have become an integral part of our lives. They allow you to forget the problems associated with handing over keys to relatives or guests from another city, restrict access to private premises or set up access control in an office building, as well as optimize the work of an administrator in a hotel.
One of the problems that is relevant for modernity is the preservation of material or personal values. Previously, it was easily resolved using a conventional padlock or mortise lock. However, today such funds are not enough.
Modern electronic locks are much more convenient and efficient than their mechanical counterparts. You can unlock such a lock with a simple key, and in a more convenient way. As the detector unlocking the electronic lock, a magnetic card, a barcode, a fingerprint or an alphanumeric code entered from the keyboard can be used.
In the case of an RFID key card, the lock operates on the principle of a FRID reader. By type of actuator, electronic door locks are electromechanical or electromagnetic.
The principle of operation of the electromagnetic lock is based, as the name implies, on the system of magnetization of metal surfaces located on the door and on the shutter body built into the door frame. Such a small device has a fairly high retention force.
For an ordinary door, this figure is 350 kg, while for an armoured door, more powerful models with a retention force of about half a ton are used.
The electronic locks are especially widely used in access control systems. They are used at various enterprises, in offices, in warehouses, etc. The possibilities offered by devices of this type are much wider than with a conventional mortise lock.
With their help, you can perform a number of accounting operations. In addition to the function of unlocking and locking doors, electronic locks allow, for example, to keep track of working hours. When an employee applies an RFID tag for unlocking, the system receives a door open signal, it records the time a particular employee arrived at the enterprise and the time he left.
Electromechanical locks look like an ordinary door lock. They are mortise or overhead. However, in order to open such a lock, voltage is required that comes from external control devices, such as a card reader, intercom, skud controller, etc.
The main feature of electromechanical locks is the electronic bolt control system. As practice has shown, in the scarcity of enterprises where a large number of people go, it is preferable to use electromagnetic models of locks.
The scope of these devices is very large. The sensor, which serves to open the electronic lock, can fulfil other roles. For example, in entertainment and sports facilities, a key card or electronic bracelet serves as an entrance ticket, as well as a key to a personal locker, and an electronic means of payment.
Digital Door Locks for hotels are much demanded today. They allow you to keep a separate record of the movements of staff: maids, technicians and other employees. At the same time, guests can enjoy the increased comfort that modern technologies provide.
