Electric mortise locks are divided into: two-wire electric mortise locks, five-wire electric mortise locks
Two-wire electric mortise lock: There are two wires, red and black, red is connected to power +12VDC and black is connected to GND. Disconnect either wire, the lock retracts, and the door opens. The two-wire electric lock is relatively simple in design and has no single-chip control circuit. The lock body is prone to heat and hot, and the inrush current is relatively large.
Five-wire electric mortise lock: There are two wires, red and black, red is connected to power +12VDC and black is connected to GND. There are also three lines of COM NO NC, which are the door magnetic signal lines, reflecting the open and closed status of the door. NO and NC respectively form two pairs of signals opposite to COM (one set of closed signal, one set of open signal). It outputs different switch signals to the access control controller through the door sensor, according to the current open or closed state of the door, for example, the illegal intrusion alarm of the access control, the door is not closed for a long time and other functions rely on these signals to make judgments. If these functions are required, the door magnetic signal line can be left unconnected. The five-wire electric mortise lock adopts a single-chip controller, with benign heat generation, delay control, and door magnetic signal output. It is a common type of electric lock with good cost performance.
The so-called delay control means that there is a DIP switch on the lock body, which can set the delay time for closing the door. Usually can be set to 0 seconds, 2.5 seconds, 5 seconds, 9 seconds. Each manufacturer's lock points and delays are slightly different.
