Electric plug lock basic buy common sense.

Electric plug lock basic buy common sense.

First of all, the lock surface should have a metallic luster, can not have an obvious scratch, standby current 300mA or so, action current should be less than 900mA. After a long time of power, the surface is slightly hot, but not hot. Electric plug lock bounce strength to be sufficient, after the press down the lock can automatically bounce and powerful, it is best to carry out 4000 times on and off test, if, found in the process of the lock is weak, or not bounce in place, or not bounce up, as unqualified. Some engineering providers ask: is the choice of two lines or multi-line plug lock? It is like this, the multi-line electric plug lock is controlled by a single-chip microcomputer, the running current of the electric lock is controlled by the single-chip microcomputer, the lock body is not too hot, and it has the function of delay control and door magnetic detection; The time delay control function can adapt to the use of the door with poor ground spring, and the door magnetic monitoring function can provide the controller with the real-time monitoring function of the opening and closing state of the door. Although these functions may not be used by you, the quality and stability of the electric lock controlled by the single-chip microcomputer and the electric lock controlled by the single-chip microcomputer are not on a level. Therefore, it is recommended that you do not have to save a little money. The two-wire electric plug lock has a very simple internal structure, which is just a current driving electromagnetic coil. The working current is large, and the heating is serious enough to damage the electric lock at some point.

The appearance should be delicate, the surface can not have obvious scratches or rust, the key to the magnetic lock is to see its resistance to tension; This requires professional equipment to measure, so only after the installation, with the hand suddenly fo rced way to pull a pull, pull not open as normal, but pay attention to the installation of electromagnetic lock body suction to match, iron suction is not installed too tight, otherwise it will affect the tension resistance.

In the selection of locks, first of all, we should distinguish the 90-degree door (one-way door) and 180-degree door (two-way door) two cases, the 180-degree door must use the electric lock, the 90-degree door can use a magnetic lock, electric lock, cathodic lock, glass door clip lock, electric lock, etc. The door closers are determined by the weight of the door, which is determined by the volume and material of the door. The stand was chosen for aesthetics, safety, and convenience.
