Types of electric locks

Electric lock devices are mainly divided into two types: "power failure open" and "power failure lock". "Power failure open" type electric lock will be unlocked when the power supply is interrupted or can be opened from within the premises, while "power failure lock" type is still locked when the power supply is interrupted. If the electric lock device installed in the building is of the type of "blackout lock", when the fire alarm occurs, the power supply is affected, this type of electric lock device will pose a potential danger to the residents. Therefore, residents should ensure that the locks installed in the safety doors of the fire escape of the building can be opened from the building without using a key when the power supply is interrupted, which has ensured the safety of life.

However, if the power-off open electric lock is installed in the door of a private residence, in order to remedy the power failure and the door opening action, it is recommended to install an uninterruptible power system UPS. To increase security.
