How to solve the problem of electromagnetic lock power failure

Electromagnetic locks have entered many families. We all know that this kind of lock is very safe. So what should we do if the electromagnetic lock loses power in our daily life?

In order to avoid the failure of access control after power outage, we can choose a power supply with a backup battery. Generally, it can maintain a working time of 5-8 hours, which is enough to deal with the control after power outage or wait. The design of electromagnetic force lock (or electromagnetic lock) is the same as that of electromagnet. It uses the principle of electromagnetism. When the current passes through the silicon steel sheet, the electromagnetic lock will generate a strong suction force to tightly absorb the adsorption iron plate to achieve the effect of locking the door.

Only a small current electromagnetic lock will generate a huge magnetic force. The access control system that controls the electromagnetic lock power supply will cut off the power after the person is correctly identified. The electromagnetic lock loses the suction force and the door can be opened. Because the electromagnetic lock does not have a complicated mechanical structure and the structure of the lock tongue, it is suitable for the passage control of escape doors or fire doors. The electromagnetic lock body is protected by an epoxy resin injection inside.

So we don’t have to worry about any accidents caused by the electromagnetic lock power failure.
