Explanation of terms

When the door is closed, the control latch extends to the striking plate and is pushed in. In combina-
tion with the position of the striking plate, a check of whether the deadbolt extends takes place ("Self-
locking", page 42).
The latch bolt engages in the locking plate and controls the function of the control latch and the auto-
matic locking.
For double-leaf variants only, unlocks the latch block by espagnolettes (passive leaf lock.)
The bolt is always extended by means of automatic locking when the door is closed.
The cylinder fixing screw is provided for the fixing of the locking cylinder in the lock case.
The face plate is screwed onto the door.
The handle pin is a square pin which is guided through the follower and ends in the door handle. With
locks with a split lock nut, the handle pin is also split.
The profile cylinder (locking cylinder) is installed in the profile cylinder cutout and screwed into place
with the cylinder fixing screw.
The backset is the distance from the keyhole centre to the front edge of the face plate.
The rear backset is the distance from the keyhole centre to the rear edge.
The striking plate is the counterpart to the lock installed in the door frame.
The rebate gap is the distance between the face plate and striking plate (Fig. 3).
