Usually the electric mortise lock consists of two main parts


Lock body and keyhole. The key component in the lock body is the “lock tongue”, which cooperates with the “lock hole” to realize the “closed door” and “open door” states. That is, the locking tongue is inserted into the locking hole to close the door, and the locking tongue is separated from the locking hole to open the door. Because of the retractable function of the tongue, it was named the "electric plug". It is also because of this feature that electric mortise locks are often used on various swing doors (two-way opening). At the same time, its "hidden" installation features are more suitable for places with high security requirements for locks.


There are two types of electric plug locks, power-on unlocking and power-off unlocking. That is, the state when the former is energized is the state in which the lock tongue is inside, and the latter is reversed. However, under normal circumstances, fire protection requires the use of power to open the door to ensure that the door can automatically open when the fire occurs.


The lock has 2 cores (power + and -) 5 cores (power + and - and gate magnetic two state points and common points) and 8 cores (power + and - and door magnetic two state points and common points and lock cylinder 3 points).
