Durable Narrow Electric Bolt Lock

BL-N2000 electric bolt lock is controlled with an intelligent circuit, and its working voltage is DC12V.A

locking delay circuit is set at the side of the lock for choice among 0/3/6/9 seconds by the user.


Locking delay can be selected to prevent from bolt's being sprung out when the door is not closed stably. 

A door detection circuit is designed in the bolt lock, which is led out of the lock through a wire for the user to detect and monitor on/off status of the door.


II. Instruction for use and installation:


1. Prior to use, please read the instruction carefully, check if major parts are complete, and prior to installation, try to simulate connection as per electric wiring diagram following working way of the electric bolt lock and perform actual installation after the lock works normally.


2. The electric bolt lock consists of two major components (1) magnet seat and (2) main body of electric bolt lock. 

At installation, interval between the magnet seat and positive side of the bolt lock shall not be more than 3mm. 

Point the bolt hole on magnet seat right at the bolt on the lock and place the magnet in the center of the lock as shown in Figure 1.


3. Led wires of six colors stick out of the tail part of the lock: red, black, brown, grey, green and orange, as shown in Figure 1. Red wire is for positive pole of power supply of the bolt, which is connected to power of DC12V (+) or positive power line of a controlled power supply.


Black wire is for negative pole of power supply of the bolt, which is connected to power of DC12V (-).


Brown wire is door-opening control wire of the lock (OPEN). When it is connected to negative pole of power supply, 

the lock will be opened. It is under control of door-opening button or access control part.


Grey, green and orange wires are door detecting wire and they are used to detect if the door is in the open or closed state.


Grey wire is public point (COM)


green wire is normally open point (NO) and orange wire is normally closed point (NC), as shown in Figure 2. 

After the door is closed in place, the connecting states of normally open and normally closed points change with each other.
