Magnetic lock: the main tricks when choosing
Magnetic lock is a fundamentally new device that works on electricity. He protects against unlawful penetration. Its principle of action is elementary and at the same time very effective. The door is held thanks to a powerful electromagnet. In the construction market there are both small locks with a holding force of 170-200 kg, and super-powerful locks from 500 to 1000 kg. Agree, a simple person is very difficult to physically reproduce such an effort. The metal in Obninsk is now very popular, during construction and repair work it is very often used by metal.
The main disadvantage of such locks is a strong dependence in energy. Disconnecting light in the house or in the office will lead to the fact that all the doors will open. However, such magnetic door locks are equipped with an additional battery with a battery that can extend life for a while.
For light office doors, it is not rational to install large magnetic locks with 600 kg retention force. For interior doors, a small castle with a deduction of 170-310 kg is most suitable for the most suitable. And for metal doors, it is advisable to use a lock with a force of retention from 400 kg and above.
The magnet itself has a protective film that greatly affects the durability and reliability of the lock. When varnishing the surface of the lock, its service life is significantly reduced, since the external influences of the environment greatly affect the state of this coating. A completely different thing, this is galvanizing. This method of protection provides a magnetic castle with the most reliable protection for a long period.
