Assembly and Operation Manual 

the lock connector block. After that install the lock in the locating pocket of the door and fasten it 
with screws from the delivery set; 
4) 

Mount the lock cylinder (7) inside the lock (1) and fix it with the screw through hole on the 

front plate of the lock (1) (lock cylinder is not included in the delivery set); 
5) 

Adjust the door levers with escutcheon plates (3) and fasten them with screws (not 

included in the delivery set);  

 

Note 

When installing the reed switch ensure the firm contact closure at closing of the door. 

6) 

Check the lock operation in day-time mode.  

Insert the key (6) into lock cylinder (7) and turn it clockwise against stop (for right-handed doors 
– clockwise direction, for left-handed doors – counter clockwise on the door front side). Holding 
the key turn the lever. The bolt should fully move inside the lock without sticking. Check that the 
lever is blocked unless the key in lock cylinder is turned.  
Closing and blocking of the lock should be checked while the door is opened. Lock closing 
(sinking of the bolt) by turning the lever must be impossible when the key is taken out.  
Check the lock operation several times at the opened door.   
7) 

Check the lock operation in night-time mode. 

In order to change day-time mode to night-time mode move up the switch on the forend. After 
that the door can be closed and the lock will automatically switch to night-time mode.  
The imitation of closing at the opened door can be made by sinking the locking bolt. The day / 
night mode switch frees the locking bolt and after sinking it moves out for additional 7.5 mm. 
After that the bolt is blocked.  
Opening of the lock in night-time mode is made by a key turn (clockwise against stop) and after 
that holding the key turn the lever. The lever should turn freely without sticking. After releasing 
the lever the lock automatically switches to day-time mode (the bolt throw is limited). Check the 
lock operation several times at the opened door.  
8) 

Check the control signal passage before fixing the lock (1) by connecting the  control cable 

to lock connector block.   
When energized the lock is blocked and impossible to open by turning the door lever.  Closing of 
the lock is checked by sinking the locking bolt (the lock is energized at that). The locking bolt 
should move freely without sticking. After the lock is energized the turn of the lever is blocked.  
Do this checking several times. 
9) 

Mounting of the strike plate (8) should be made in the following order: 

  make the carving in the door frame according to Fig. 3; 

  mount the strike plate (8) into the door frame providing 1.5 – 3 mm spacing between 

the strike plate and the forend (2) when the door is closed. The channel of the strike 
plate (Fig. 3) must lay symmetrical to bolt’s cross section; 

  fix the strike plate with screws from the delivery set.  

If the lock is operated as a part of access control system (ACS) it is recommended to install the 
voltage regulator diode BZW06-15B or P6KE16CA (or another model with equal parameters) on 
contact clips.   

 

Note 

The voltage regulator diode is used for maintaining the device which sends the control 
signal.
